Diabetes Mellitus Nursing Care Plans: 20 Nursing Diagnosis

Diabetes is the patient you will see on every unit, in every specialty, at every age. Your job rarely starts and stops with the glucose number on the meter. You are watching for the lows that drop a patient before lunch, the highs that tip a type 1 into ketoacidosis, the silent MI, the foot ulcer that started as a blister, and the teaching gaps that send people back through the door. Keep glucose in range, catch the acute swings early, and build the self-care skills that keep the patient out of the hospital. That is the work.

What is Diabetes Mellitus?

Diabetes mellitus (DM) is a chronic disease in which the pancreas makes too little insulin or the body cannot use the insulin it makes. Glucose climbs in the bloodstream (hyperglycemia), and carbohydrate, protein, and fat metabolism all go off. Sustained hyperglycemia damages nearly every tissue, with the eyes, nerves, kidneys, and blood vessels taking the heaviest hits.

Classifications:

• Type 1 diabetes: destruction of pancreatic beta cells leading to absolute insulin deficiency, including latent autoimmune diabetes of adulthood.
• Type 2 diabetes: progressive loss of pancreatic beta cells with insulin resistance and impaired insulin secretion.
• Specific types due to other causes: monogenic syndromes (neonatal diabetes, maturity-onset diabetes of the young), exocrine pancreatic disease (cystic fibrosis, pancreatitis), and drug- or chemical-induced diabetes (glucocorticoids, HIV/AIDS treatment, organ transplantation).
• Gestational diabetes mellitus (GDM): diabetes diagnosed in the second or third trimester that was not overt diabetes before conception.

Screening and diagnostic criteria for prediabetes and diabetes:

Screening Test	Prediabetes	Diabetes
A1C	5.7-6.4%	6.5% or greater
FPG	100-125 mg/dL	126 mg/dL or greater
2-hour plasma glucose, 75-g OGTT	140-199 mg/dL	200 mg/dL or greater
Random plasma glucose	N/A	200 mg/dL or greater

Nursing Care Plans and Management

The goal is normal or near-normal blood glucose with the fewest complications, using insulin or oral agents, a balanced diet, and exercise. Most of your leverage is in teaching. Tailor it to the patient's needs, abilities, and developmental stage, and make the link between glucose control and long-term health concrete.

Nursing Problem Priorities

1. Glycemic control. Keep blood glucose in range with medication, diet, and lifestyle.
2. Education and self-management. Medication administration, glucose monitoring, meal planning, exercise, and recognizing hypo- and hyperglycemia.
3. Preventing complications. Address cardiovascular risk, nephropathy, retinopathy, and neuropathy.
4. Weight management. Promote a healthy weight through nutrition and activity, accounting for comorbidities.
5. Foot care. Hygiene, daily inspection, and early action on neuropathy or ulcers to prevent amputation.

Nursing Assessment

Symptoms track with how high the glucose runs: polyuria, polydipsia, polyphagia, plus fatigue, vision changes, numbness, dry skin, slow wound healing, and recurrent infection. Diagnosis rests on blood glucose. Ongoing assessment for complications is part of every encounter.

Assess for the following subjective and objective data:

• Polyuria from osmotic diuresis.
• Polydipsia from fluid loss and dehydration.
• Polyphagia from the catabolic state of insulin deficiency and breakdown of protein and fat.
• Fatigue and weakness.
• Sudden vision changes.
• Tingling or numbness in the hands or feet.
• Dry, rough, or flaky skin.
• Slow-healing wounds.
• Recurrent infections.
• Sudden weight loss (type 1).
• Nausea, vomiting, or abdominal pain (type 1 with DKA).

Nursing Diagnosis

After assessment, nursing diagnoses are shaped by your clinical judgment and the patient's specific picture. Common ones in diabetes:

• Imbalanced Nutrition: Less Than Body Requirements related to inadequate or excessive intake and increased metabolic demand, as evidenced by weight loss, decreased muscle mass, and fatigue.
• Unstable Blood Glucose Levels related to inconsistent meals, inactivity, and insufficient knowledge of management.
• Knowledge Deficit related to new diagnosis, as evidenced by questions about disease management and insulin administration.
• Risk for Infection as evidenced by hyperglycemia and delayed wound healing.
• Ineffective Health Maintenance related to limited understanding, as evidenced by irregular monitoring and missed doses.
• Fatigue related to decreased energy production.
• Risk for Impaired Skin Integrity as evidenced by decreased sensation and poor circulation.
• Activity Intolerance related to muscle weakness.
• Risk for Disturbed Sensory Perception as evidenced by blurred vision.

Nursing Goals

Goals and expected outcomes may include:

• The patient maintains blood glucose less than 180 mg/dL, fasting glucose less than 140 mg/dL, and A1C below 7%, and identifies the factors that affect glucose stability.
• The patient demonstrates insulin injection technique, recognizes and treats hypoglycemia, and understands dietary requirements.
• The patient acknowledges feelings of helplessness, names healthy coping strategies, and takes responsibility for self-care.
• The patient demonstrates diabetes self-care and explains the disease process, potential complications, and the rationale for their actions.
• The patient consumes appropriate calories and nutrients, shows usual energy, and stabilizes or trends toward target weight with lab values in range.

Nursing Interventions and Actions

1. Providing Patient Education on Diabetes Management

Good diabetes care runs on diabetes self-management education and support (DSMES). Assess the need for it at four critical points: diagnosis, annual reviews or when targets are missed, when complications arise, and during life and care transitions. Keep it person-centered, individual or group, with the whole care team involved. Education drives adherence more than almost anything else you do.

Nursing Diagnosis

• Knowledge Deficit related to diabetes management, as evidenced by limited understanding of the disease, treatment, and self-care.
• Readiness for Enhanced Health Management as evidenced by interest in learning, active participation, and questions about self-care.

Expected Outcomes

• The patient explains the disease process and the importance of glucose control.

Assessing readiness to learn

Assess the patient's and family's readiness to learn so you can match pace and approach to their emotional readiness and capacity.

Assess baseline knowledge of pathophysiology, treatment, and recognition, treatment, and prevention of acute complications. This tells you where to start and lets you build an individualized plan.

Assess the social situation: literacy, finances, insurance, daily schedule, family support, learning disabilities, and cultural beliefs. These are the barriers that derail a plan, and naming them lets you work around them.

Provide emotional support through the grieving that follows diagnosis. Patients move through shock, denial, anger, depression, bargaining, and acceptance. Support helps them get to a place where teaching lands.

Reassess self-care in patients who have had diabetes for years. Errors creep in over time. Watch a return demonstration rather than trusting self-report.

Ask about the patient's and family's biggest fears and concerns. This surfaces misconceptions you can correct and lowers anxiety.

Initiating diabetes education

Give simple, direct information to clear up misconceptions about diabetes, its treatment, and self-management.

Teach the basics: what diabetes is, normal glucose ranges, and target glucose levels. Patients who understand the why are more likely to stick with the plan.

Teach the treatment tools: insulin, oral agents, meal planning, and monitoring of glucose and urine ketones. Self-monitoring skills put the patient in the driver's seat.

Teach recognition, treatment, and prevention of hypoglycemia and hyperglycemia. Catching acute swings early keeps people out of the ED.

Frame education as lifelong, both formal and informal.

Build a deeper plan around the patient's interests: carbohydrate counting, insulin adjustment, and prevention of long-term complications.

Prioritize foot care and eye care. Early detection here is what prevents amputations and blindness.

For hospitalized patients, start basic skills early so they can practice under supervision before discharge. Lengths of stay are short, so do not wait.

Plan for followup in the home setting to reinforce what was learned on the unit.

Adapt the plan to the patient's cultural beliefs and practices, which directly affect adherence.

Bring in the multidisciplinary team, including diabetes educators and specialists, for advanced and individualized teaching.

Considerations for pediatric patients

Assess the parent's and child's understanding, learning capacity, and developmental level. Children ages 8 to 10 can often take on some of their own care.

Teach in a quiet space, in small amounts, with demonstration and return demonstration. Start one day after diagnosis and keep sessions to 30 to 60 minutes.

Include as many family members as possible to build understanding, support, and the child's sense of security.

Teach cause, disease process, and pathology using pamphlets and aids matched to the child's age and the parents' comprehension.

Teach insulin administration: drawing insulin into the syringe, rotating the vial rather than shaking, drawing clear insulin first when mixing two types in one syringe, subcutaneous injection, storage, site rotation, dose adjustment, and safe syringe and needle disposal.

Teach the use of a syringe-loaded injector as an alternative for a child afraid of skin puncture.

Teach operation of a portable insulin pump for continuous subcutaneous insulin infusion.

Teach blood glucose monitoring 4 times a day (before meals and before bed) with a lancet and meter or reagent strip, plus urine testing with Ketostix or Clinitest for glucose and ketones.

Teach meal planning: proper meal times, adequate calories for age, how activity changes intake, judging portion sizes, and acceptable choices from fast-food restaurants.

Teach how exercise changes food and insulin needs with increased or decreased activity.

Teach skin care, regular dental exams, foot care, nail care, infection prevention, eye exams, and immunizations.

Teach the family to keep a record of insulin, glucose readings, diet and exercise responses, and any deviations, so the provider can adjust the regimen.

Teach the child to wear or carry identification with disease, treatment, and provider information for emergencies.

Considerations for older adults

Regularly evaluate self-care skills (insulin, glucose monitoring, foot care, diet), especially with declining vision or memory. Timely reassessment lets you adapt and add support.

Match the glucose meter to the patient's vision, cognition, and dexterity so monitoring stays accurate and doable at home.

Provide written instructions and handouts to take home as a reference for the patient and family.

Involve family members in basic skills when physical or cognitive limits make tasks hard.

2. Achieving Glycemic Control and Blood Glucose Monitoring

The point of glucose control is to head off the neuropathic and vascular complications that do the long-term damage. Tight control slows their development and progression.

Nursing Diagnosis

• Risk for Unstable Blood Glucose Levels as evidenced by limited diabetes knowledge, inconsistent self-care, and barriers such as limited resources, lack of support, or cultural beliefs.

Expected Outcomes

• The patient maintains glucose within target through self-monitoring and adherence.
• The patient recognizes early hypo- and hyperglycemia and responds appropriately.

Self-Monitoring of Blood Glucose (SMBG)

SMBG lets patients personalize treatment and hold glucose in range.

Teach proper SMBG technique so readings are accurate and treatment decisions are sound.

Assess visual acuity, fine motor coordination, and cognition to pick the right SMBG method. Success depends on the patient being able to do the task.

Encourage calibrating readings to plasma values and checking validity with control solutions to confirm the meter and strips are working.

Evaluate technique regularly, comparing SMBG against laboratory glucose to catch errors and retrain as needed.

Provide guidance on meter cleaning and maintenance.

Help the patient understand insurance coverage for meters and strips so cost does not interrupt monitoring.

Set SMBG frequency to the patient's insulin regimen, medication changes, activity, and suspected highs or lows.

Teach the patient to keep a logbook or app and read the patterns, linking diet, medication, and activity to their glucose.

Use positive reinforcement and work through barriers like cost. Supported patients keep monitoring.

Continuous Glucose Monitoring System (CGMS)

Teach the purpose, function, and use of CGMS so the patient can act on the data.

Assist with inserting and connecting the sensor and device for accurate, reliable readings.

Work with the team to download and analyze the data and adjust the plan.

Explain that CGMS gives 24-hour monitoring, catching fluctuations across day and night that spot checks miss.

CGMS is especially useful in type 1 diabetes, where patients depend on external insulin and need the trend data to dose well.

Monitoring Glycated Hemoglobin (A1C)

A1C reflects glucose control over the past 3 months.

Teach what A1C means and how to read it, so the patient understands their long-term control and stays engaged in care.

Work with the patient on strategies to reach and hold target A1C. The typical range is 4% to 6% (near-normal glucose); the target in diabetes is less than 7%.

Monitoring Ketones

Ketones are byproducts of fat breakdown that accumulate in blood and urine. Urine ketone testing is indicated in type 1 diabetes with glycosuria or glucose persistently over 240 mg/dL (13.2 mmol/L) on two consecutive tests, during illness, in pregnancy with preexisting diabetes, and in gestational diabetes.

Teach correct use of urine dipsticks (Ketostix, Chemstrip uK, or others) for ketones and glucose. These flag deteriorating control.

Have the patient test urine ketones whenever there is glycosuria or glucose stays above 240 mg/dL (13.2 mmol/L) for two readings in a row, so insulin deficiency is caught early.

Explain the link between ketones in the urine and insulin deficiency to reinforce regular monitoring.

Have the patient increase ketone testing frequency during illness or pregnancy, when insulin needs shift.

Patients who are NPO

Adjust insulin for NPO status to prevent highs and lows. This may mean holding rapid-acting insulin, decreasing intermediate-acting insulin, or switching to basal insulin or frequent rapid-acting dosing.

Give basal insulin to type 1 patients who are NPO. Eliminating insulin entirely in type 1 invites DKA.

Test glucose and dose insulin regularly during prolonged NPO. Regimens may include NPH insulin every 12 hours, frequent rapid-acting doses, or an IV insulin drip, with dextrose infusions to supply calories and limit ketosis.

Teach clear-liquid choices that hold glucose steady. Juice and gelatin are simple carbohydrates that spike glucose if taken alone.

Patients on enteral tube feedings

Dose insulin on a schedule aligned with the feeding, such as NPH every 12 hours or regular insulin every 4 to 6 hours, since high-carbohydrate formulas raise glucose during continuous feeds.

Coordinate with the team before any feeding is held. Stopping a feed in a patient who got insulin can cause hypoglycemia, so plan a dose adjustment or IV dextrose ahead of time.

Respond fast to feeding problems (dislodgement, clogging, held feeds). Notify the provider, increase glucose checks, and give IV dextrose when indicated.

Patients on parenteral nutrition

Add IV insulin to the parenteral nutrition container for continuous PN to control glucose and prevent hyperglycemia.

Coordinate subcutaneous insulin with limited-duration PN so insulin peaks line up with the infusion.

Monitor glucose regularly on PN and adjust insulin to prevent highs and lows.

Glucose control during stress

Monitor glucose closely during physiologic stress such as infection or surgery, which drives hyperglycemia and can precipitate DKA or hyperosmolar hyperglycemic state (HHS).

Support the patient emotionally during hospitalization. Stress worsens control, so lowering it helps.

Teach the stress-glucose link and the importance of staying with the plan during stressful stretches.

Teach stress management and coping: deep breathing, mindfulness, exercise, social support, and professional help when needed. Build these into the broader diabetes education.

3. Insulin Therapy and Normalizing Insulin Activity

Type 1 patients need insulin for life. Type 2 patients may need it when other treatments fall short. Either way, monitoring and dose adjustment keep glucose steady and complications down.

Nursing Diagnosis

• Deficient Knowledge related to insulin therapy, as evidenced by limited understanding of administration technique, timing, and complications.

Expected Outcomes

• The patient demonstrates correct administration with proper timing and site rotation.
• The patient explains insulin types and their onset, peak, and duration, and how they relate to meals and glucose.
• The patient demonstrates safe storage, preparation, and syringe disposal.

Educating patients on insulin therapy

Assess readiness and ability to take on insulin therapy so you can match the regimen to the patient's lifestyle.

Assess cognitive and physical ability to manage a complex regimen of multiple injections, monitoring, and record-keeping, or simplify it.

Assess injection technique and correct any errors or misconceptions.

Administer insulin as prescribed. In type 1, exogenous insulin is required for life; in type 2, it is added long-term when other options fail or insulin deficiency develops.

Insulins

Teach the available insulin regimens with their tradeoffs so the patient can take part in the decision.

Teach how meals drive insulin needs. Rapid- or short-acting insulins cover the post-meal glucose rise; intermediate-acting insulins cover later meals.

Teach SMBG and carbohydrate counting so the patient can match doses to intake and keep flexibility in meals.

Teach the practical logistics: where to buy and store insulin, syringes, and supplies, and when and how to reach the provider.

Teach timing. Rapid-acting insulins go shortly before meals; basal insulins are taken consistently regardless of meals.

Monitor the response to insulin, including glycemic control and adverse effects, and adjust the regimen.

Watch for hypo- and hyperglycemia. Early detection allows prompt correction.

Teach prevention and management of hypoglycemia. Intensive regimens carry higher hypoglycemia risk.

Teach consistent, error-free preparation, since dosing errors and wrong-insulin errors undercut control.

Teach the order for mixed insulins: draw regular insulin first for accurate, consistent dosing.

Do not inject cloudy insulin into a vial of clear insulin. It contaminates the vial and alters insulin action.

Offer alternatives for patients who struggle to mix insulins: premixed insulins, prefilled syringes, or separate injections.

Insulin storage and syringe safety

Refrigerate unused vials and pens, including spares, to preserve potency.

Keep insulin away from extreme temperatures: freezing, direct sunlight, and hot car interiors all degrade it.

Keep the in-use vial at room temperature to reduce injection-site irritation.

A vial in use can stay at room temperature for up to 1 month without losing effectiveness.

Mix cloudy insulins by inverting the vial or rolling it between the hands for an even, consistent dose.

Check the expiration date on every insulin before use.

Inspect intermediate-acting insulin for flocculation, a frosted whitish coating that signals temperature damage. Discard it.

Match syringe size to the dose. Insulin syringes come in 1mL, 0.5mL, and 0.3mL sizes with different unit increments; the right size prevents measurement errors.

Use a new disposable needle for each injection to keep needles sharp, reduce pain and infection risk, and ensure accurate delivery.

Keep the needle capped when not in use to maintain sterility.

Do not share syringes. Sharing transmits bloodborne infections, including HIV and hepatitis.

Teach safe syringe disposal: clip the needle or use a sharps container to prevent needlestick injuries.

Point the patient to local regulations and resources (refuse company or waste authority) for disposing of used syringes.

For travel, pack used syringes in a secure container to prevent accidental needlesticks.

Insulin pumps (continuous subcutaneous insulin infusion)

Assess suitability. Pump therapy fits patients who want continuous infusion and will commit to frequent monitoring and close work with the team.

Provide extensive education on operation, site care, troubleshooting, monitoring, and dose calculation from carbohydrate counting.

Teach the risks: occlusions in the set or tubing, interrupted insulin flow, and a higher risk of ketoacidosis. Teach the patient to recognize occlusions, give manual injections when needed, and seek help fast.

Teach care and maintenance, including regular infusion-set changes, hygiene, safe storage, and battery replacement.

Monitor the response and adjust doses and troubleshoot to keep control.

Support the patient around wearing the pump 24 hours a day, including options for temporary disconnection for showering, exercise, swimming, or sexual activity.

Insulin pens

Pens suit patients who inject one type of insulin at a time or use premixed insulins. Assess the regimen and needs to decide if a pen fits.

Teach technique and safety: loading the cartridge, dialing the dose, attaching the disposable needle, and injecting.

Teach storage and maintenance: avoid temperature extremes, clean regularly, and replace needles.

Monitor the response and adjust doses to keep control.

Insulin jet injectors

Jet injectors deliver insulin without a needle. Assess the regimen, preferences, and needs to decide if one fits.

Provide thorough training and supervision when starting, covering operation, hygiene, and troubleshooting.

Teach that absorption rate, peak activity, and insulin levels can differ from needle injection, so self-management may need adjusting.

Warn about possible bruising at the site.

4. Preventing Complications of Insulin Therapy

Insulin can cause local reactions (redness, swelling, tenderness, wheals at the site) and, rarely, systemic reactions (generalized urticaria or anaphylaxis).

Preventing allergic reactions

Assess and monitor injection sites for local reactions. If they persist, an alternative insulin may be prescribed.

Teach the patient about systemic reactions. They are rare but can present as urticaria or anaphylaxis, and the patient must seek immediate care. Desensitization with gradually increasing doses may be needed.

Preventing lipodystrophy

Teach lipodystrophy and site rotation. Lipodystrophy is a localized reaction at injection sites, either lipoatrophy (loss of subcutaneous fat) or lipohypertrophy (fibrofatty masses). Human insulin has cut its incidence; rotating sites prevents lipohypertrophy and the delayed absorption that comes with it.

Watch for insulin resistance and work with the team on doses. Some patients need higher doses for adequate control.

Managing morning hyperglycemia

Teach the causes of morning hyperglycemia: the dawn phenomenon, insulin waning, and the Somogyi effect. Overnight monitoring identifies which one is at play so doses and timing can be adjusted.

Address insulin waning with timing. Waning is a progressive glucose rise from bedtime to morning; giving the evening NPH dose at bedtime rather than before dinner prevents it.

5. Administering Oral Antidiabetic Agents

Oral antidiabetic agents are for type 2 patients who do not respond to medical nutrition therapy (MNT) and exercise alone. They supplement, not replace, the rest of the plan, and may need to be held for insulin if hyperglycemia develops.

Assess the patient's understanding of oral agents and their role, since adherence depends on it.

Assess knowledge of the drug classes and their mechanisms so the patient can take part in the plan.

Teach that oral agents work alongside MNT and exercise, which boost their effectiveness.

Monitor glucose regularly, especially during infection, trauma, or surgery, which may force a temporary switch to insulin.

Teach insulin as a possible add-on, especially for newly diagnosed type 2 patients with symptomatic hyperglycemia and high glucose and A1C. Clearing up fears about insulin improves acceptance.

Stress regular followup and labs to evaluate the response and adjust treatment.

Have the patient report adverse effects or symptom changes promptly so problems get caught early.

6. Promoting Nutritional Balance and Weight Management

Nutrition is where most patients win or lose glucose control. Healthy choices, portion control, and balanced meals move glucose, lipids, and blood pressure together.

Dietary assessment

Assess dietary history, preferences, lifestyle, and cultural background. A plan that ignores these will not be followed.

Calculate energy and caloric needs from age, sex, height, and weight for the baseline intake that maintains weight.

Factor in activity level for a more accurate calorie target.

Subtract 500 to 1000 calories from the daily total for safe, gradual loss of 1 to 2 pounds per week.

Meal planning

Simplify meal-planning information and build in practice and repetition. Exchange systems trip people up; repetition builds confidence.

Distribute calories across carbohydrate, protein, and fat to the patient's needs.

Teach the recommended caloric distribution:

• Carbohydrates. About 60% of calories. Carbohydrates raise glucose the most because they digest fastest; take them in moderation to blunt postprandial spikes.
• Fats. About 20-30% of calories, kept under 30% with limited saturated fat. Keep dietary cholesterol under 300 mg/day to reduce coronary artery disease, the leading cause of death and disability in diabetes.
• Protein. About 10-20% of intake. Use nonanimal sources (legumes, whole grains, nuts) to cut saturated fat and cholesterol.
• Fiber. Increase it. Fiber improves glucose, lowers insulin needs, and lowers total and LDL cholesterol.

Emphasize fiber for glucose, cholesterol, and satiety, from legumes, whole grains, fruits, and vegetables.

Increase fiber gradually with a dietitian. Sudden increases cause GI discomfort and may require insulin or oral-agent dose changes to prevent hypoglycemia.

Teach exchange lists to organize foods by similar calorie and macronutrient content for balanced, varied meals.

Teach label reading and carbohydrate content, which patients on premeal insulin need to dose accurately.

Teach carbohydrate counting, which gives flexibility while holding glucose, in both type 1 and type 2.

Teach healthy choices, portion control, and serving sizes using standard portions or the MyPlate Food Guide.

Discuss the glycemic index, how much a food raises glucose compared with an equivalent amount of glucose.

Have the patient check glucose after specific foods to build their own glycemic index and adjust meals and doses accordingly.

Stress consistent meal timing and portions. Skipped meals cause swings and overwork the pancreas.

Support lifestyle change with motivation and education.

Encourage weight loss and maintenance, which is central for patients with obesity. Losing weight improves glucose, cuts medication needs, and can delay progression from prediabetes to type 2.

Address the emotional side of dietary change, including feelings of deprivation. Frame meal planning as a new way of thinking about food, not a punishment.

Provide behavioral therapy and ongoing nutrition counseling to sustain new habits.

Collaborate with a registered dietitian for medical nutrition therapy matched to the patient's needs and goals.

Communicate clearly between the patient and dietitian, reinforcing the plan and answering questions.

Teach the food-insulin relationship. Consistent calories and carbohydrates at each meal matter most for patients using insulin to control glucose.

Alcohol consumption

Stress moderation and teach the diabetes-specific risks of alcohol.

Warn about hypoglycemia, especially with insulin or insulin secretagogues, and the need to eat when drinking.

Pair food with alcohol to lower hypoglycemia risk, while noting that carbohydrates taken with alcohol can raise glucose.

Discuss alcohol's effect on weight, hyperlipidemia, and glucose, and the need to count its calories in the plan.

Sweeteners and sugar-free foods

Suggest lower-calorie or less-sweet drinks such as light beer or dry wine.

Teach the types of sweeteners and use them in moderation. Distinguish nutritive sweeteners (fructose, sorbitol, xylitol) from nonnutritive ones, since the nutritive ones carry calories and affect glucose.

Flag side effects such as the laxative effect of sorbitol.

Explain that "sugarless" and "sugar-free" foods made with nutritive sweeteners still carry calories and can raise glucose, so they are not unlimited.

7. Encouraging Regular Exercise and Physical Activity

Exercise lowers glucose, improves insulin use, and cuts cardiovascular risk. It is one of the few interventions that works on all three at once.

Give frequency and duration guidelines: at least 3 sessions per week with no more than 2 consecutive days off. The American Diabetes Association recommends:

• Children and adolescents with type 1, type 2, or prediabetes: at least 60 minutes per day of moderate- to vigorous-intensity aerobic activity, plus vigorous muscle- and bone-strengthening activity at least 3 days per week.
• Most adults with type 1 or type 2: 150 minutes or more of moderate- to vigorous-intensity aerobic activity per week over at least 3 days. Younger, fit individuals may do shorter vigorous or interval training (minimum 75 minutes per week). Resistance exercise 2-3 times per week on nonconsecutive days.

Teach adults with type 2 to cut sedentary time and interrupt prolonged sitting every 30 minutes for glucose benefit. Older adults should add flexibility and balance training 2-3 times per week (yoga, tai chi). Have patients raise non-sedentary activity above their baseline.

Discuss the benefits of exercise plus diet in type 2, especially with overweight or obesity: better glucose metabolism, more fat loss, improved insulin sensitivity, and lower medication needs.

Increase exercise duration gradually to avoid strain and injury.

Recommend walking. It is low-impact, accessible, needs only good shoes, and fits into daily life.

Have the patient see their provider for a medical evaluation before starting, to clear underlying problems and tailor the plan.

Exercise precautions

Check glucose and ketones before exercise. If glucose exceeds 250 mg/dL (14 mmol/L) with ketones in the urine, postpone until ketones are negative and glucose is closer to normal. Exercising with high glucose drives it higher.

Teach a pre-exercise snack for insulin-treated patients: a 15-g carbohydrate snack, or complex carbohydrate with protein, before moderate exercise to prevent hypoglycemia.

Teach management of post-exercise hypoglycemia, which can hit hours later in insulin-treated patients. A snack after exercise and at bedtime plus more frequent monitoring helps; capable patients can learn to adjust doses with a diabetes educator.

Teach glucose monitoring before, during, and after extended exercise, with carbohydrate intake adjusted to stay in range.

Tell exercise partners and observers about the patient's diabetes so they can help during severe hypoglycemia.

Modify exercise for patients with complications such as retinopathy, autonomic neuropathy, sensorimotor neuropathy, and cardiovascular disease.

Stress proper footwear and protective equipment, especially with peripheral neuropathy and reduced lower-extremity sensation.

Have the patient inspect the feet daily after exercise to catch blisters or wounds before they become ulcers.

Advise avoiding exercise in extreme heat or cold and during periods of poor metabolic control.

Exercise precautions in older adults

Assess physical capacity and functional limits before starting an exercise program.

Build an individualized plan with low-impact activity (walking, swimming), balance work (tai chi), and flexibility training (stretching) to improve mobility and cut fall risk.

Stress gradual progression and frequent rest breaks, since older adults need more recovery time.

Teach the use of assistive devices (canes, walkers) and safe exercise technique to prevent falls and strains.

Use social support and group activities for motivation and adherence.

8. Preventing Hyperglycemia

Hyperglycemia is common in hospitalized patients. Drivers include regimen changes, corticosteroids, inadequate insulin with IV dextrose, poor insulin management, and mismatched meal and insulin timing.

Assess the patient's home routine for insulin, meals, and activity so you can approximate it in the hospital.

Monitor glucose regularly. It is a vital sign and tells you when extra insulin is needed.

Get orders for extra insulin doses when glucose is elevated, given at the right times.

Do not withhold insulin when glucose is normal. Withholding it lets glucose climb.

Test glucose before meals and dose insulin then to prevent postprandial spikes.

Give short-acting insulin to cover post-meal glucose, even when premeal glucose is normal.

Use corticosteroids (for example, prednisone) cautiously and monitor glucose closely, adjusting insulin as needed.

Use normal saline rather than dextrose solutions for IV antibiotics when possible, to limit dextrose load.

Avoid overly aggressive treatment of hypoglycemia, which causes rebound hyperglycemia.

9. Preventing Hypoglycemia

In the hospital, hypoglycemia usually comes from too much insulin or delayed meals.

Follow the hospital hypoglycemia protocol for consistent, safe treatment.

Assess the pattern of glucose values and avoid repeated insulin doses that keep causing lows.

Repeat treatment if the first does not raise glucose enough, following the set interval (for example, 15 minutes).

Limit successive doses of subcutaneous regular insulin to no more than every 3 to 4 hours, since stacking doses causes lows.

Use caution with supplemental regular insulin in patients already on intermediate insulin before breakfast and dinner, to avoid overlapping peaks.

Arrange snacks when meals are delayed for procedures, physical therapy, or other activities.

Monitor for hypoglycemia: sweating, tremor, tachycardia, confusion, and behavior changes.

Give fast-acting carbohydrate (fruit juice, glucose gel) as ordered to raise glucose.

Give glucagon as prescribed when the patient is unconscious or cannot swallow. It triggers hepatic glucose release and can be lifesaving.

Support the patient emotionally during episodes to lower anxiety and keep them engaged.

Teach the patient and caregivers to recognize and manage hypoglycemia, including fast-acting carbohydrate and glucagon.

Teach early recognition and prompt treatment to keep episodes from worsening.

Teach fast-acting carbohydrate management (fruit juice, glucose tablets) and the right amounts.

Teach caregivers glucagon use for emergencies when the patient is unconscious or cannot swallow.

Stress glucose monitoring before driving or other potentially dangerous activities.

Teach the lifestyle factors behind hypoglycemia: meal timing, activity, and medication adherence.

Have the patient carry a source of simple sugar (glucose tablets) at all times.

10. Preventing Diabetic Ketoacidosis (DKA)

Monitor for DKA: hyperglycemia, dehydration, electrolyte imbalance, and acidosis.

Give IV fluids (normal saline or half-strength NS) as ordered to rehydrate, restore perfusion, and help clear glucose and ketones.

Monitor vital signs, including blood pressure, heart rate, and orthostatic changes, to guide fluid replacement.

Monitor electrolytes, especially potassium, and replace as indicated. DKA causes hyperkalemia or hypokalemia, and cautious potassium replacement prevents rapid shifts and dysrhythmias.

Give insulin as prescribed, usually continuous IV infusion, to stop ketone production and correct acidosis until subcutaneous insulin can resume.

Teach sick-day rules, above all never to eliminate insulin doses during nausea or vomiting.

11. Preventing Hyperosmolar Hyperglycemic State (HHS)

Monitor for HHS: hypotension, profound dehydration, tachycardia, and neurologic changes.

Give IV fluids (0.9% or 0.45% normal saline) as ordered to rehydrate and restore volume.

Monitor vital signs, intake and output, and electrolytes. Watch fluid balance and urine output closely given the high risk of kidney failure from severe dehydration. HHS mostly affects older patients, so assess cardiovascular, pulmonary, and kidney function through the acute and recovery phases.

Give potassium supplements as indicated and monitor levels to prevent dysrhythmias.

Give insulin as prescribed. It plays a smaller role than in DKA, usually as a continuous low-rate infusion.

Monitor neurologic status closely, including mental status and focal deficits, to gauge response and catch cerebral dehydration.

Teach self-management to prevent recurrence: medication adherence, lifestyle changes, and regular monitoring.

12. Minimizing Risk for Cardiovascular Disease

Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of death in diabetes. It hits the medium and large vessels, producing thickening, sclerosis, and plaque that obstruct flow. The three main macrovascular complications are coronary artery disease, cerebrovascular disease, and peripheral arterial disease.

Assess cardiovascular risk factors: obesity or overweight, hypertension, dyslipidemia, smoking, family history of premature coronary disease, chronic kidney disease (CKD), and albuminuria. Patients with diabetes have a higher risk of myocardial infarction, with more complications and recurrence, and MIs may be silent because of autonomic neuropathy.

Teach risk-factor control: weight, blood pressure, lipids, and smoking cessation.

Monitor blood pressure at every visit and encourage home monitoring. Individualize targets to cardiovascular risk and patient preference. Use lifestyle interventions (weight loss, DASH eating pattern, reduced sodium, more activity) and start antihypertensive drugs when blood pressure stays elevated, often in combination.

Encourage lifestyle modifications: MNT, weight loss when indicated, DASH eating pattern, reduced sodium, moderate alcohol, and more activity.

Administer prescribed medications for blood pressure, lipids, and glucose. For lipids, use a Mediterranean or DASH pattern, reduce saturated and trans fats, increase activity, and use statin therapy for primary and secondary prevention based on age, ASCVD risk, and baseline LDL. Add agents such as ezetimibe or icosapent ethyl in selected cases. Use aspirin antiplatelet therapy for secondary prevention in patients with a history of ASCVD; consider dual antiplatelet therapy after an acute coronary syndrome. Do not screen for coronary artery disease in asymptomatic patients whose risk factors are well treated, but investigate with atypical cardiac symptoms, signs of vascular disease, or ECG changes.

Monitor glucose in patients with symptoms of acute diabetic complications or stroke. High glucose worsens stroke outcomes and can mimic acute diabetic emergencies, so prompt assessment helps distinguish them. Cerebrovascular disease is more common in diabetes, and atherosclerosis in the lower-extremity vessels raises the risk of gangrene and amputation.

Promote statin adherence for lipid management, especially with ASCVD or high cardiovascular risk.

13. Minimizing Risk for Diabetic Retinopathy

Patient teaching here centers on regular eye exams, glucose and blood pressure control, and self-care.

Perform frequent visual exams to catch early retinal changes and refer to ophthalmology. Screening includes initial and followup dilated exams by an ophthalmologist or optometrist, more often if retinopathy is present or progressing.

Teach the importance of regular eye exams, medication adherence, and eye self-care. Retinal photography can serve as an alternative screen. Refer promptly for macular edema and any nonproliferative or proliferative retinopathy.

Stress glucose control. Near-normal glucose through intensive therapy significantly cuts the risk and progression of retinopathy in type 1 and type 2.

Help with transportation so patients can keep ophthalmology and followup appointments.

Teach correct administration, dosing schedules, and side effects of prescribed eye medications.

Monitor for complications such as macular edema or vitreous hemorrhage and report changes promptly.

Teach eye self-care: hygiene, UV protection, and the warning signs that need immediate attention.

14. Minimizing Risk for Chronic Kidney Disease

Nephropathy comes from microvascular damage. Sustained high glucose stresses the filtration system, leaks protein, and raises pressure in the kidney's vessels.

Monitor glucose regularly. Intensive control reduces early nephropathy in type 1 and lowers overt nephropathy in type 2.

Assess urinary albumin annually and check for microalbumin, the earliest sign of kidney damage. Patients with type 1 (duration 5 years or more) and all patients with type 2 get an annual urinary albumin (spot UACR) and eGFR. Established diabetic kidney disease (DKD) gets urinary albumin and eGFR 1-4 times per year depending on stage.

Monitor serum creatinine and BUN to evaluate kidney function and guide treatment.

Give ACE inhibitors or angiotensin receptor blockers (ARBs) as indicated for hypertension in diabetes with kidney disease. They lower blood pressure and reduce proteinuria. Do not use them for primary prevention of CKD in patients with normal blood pressure, normal urinary albumin, and normal eGFR.

Teach a low-sodium, low-protein diet. Low sodium controls blood pressure; low protein reduces the kidney's workload.

Monitor for worsening function: increased proteinuria, decreased urine output, fluid retention, and electrolyte changes.

15. Minimizing Risk of Infection

Infections are more frequent and more serious in diabetes. The hyperglycemic environment impairs neutrophil function, the antioxidant system, and humoral immunity, and micro- and macroangiopathy, neuropathy, reduced antibacterial activity of urine, GI and urinary dysmotility, and frequent procedures all add risk.

Nursing Diagnosis

• Risk for Infection as evidenced by hyperglycemia, impaired immune function, and potential skin and mucous membrane breakdown.

Expected Outcomes

• The patient stays free of infection (normal temperature, no purulent drainage, clear urine) during the hospital stay.

Monitor for signs of infection and inflammation: fever, flushed appearance, wound drainage, purulent sputum, cloudy urine. An infection may have precipitated the ketoacidosis, and nosocomial infection is a risk too.

Teach and promote hand hygiene, the single most effective way to prevent transmission.

Maintain asepsis during IV insertion, medication administration, and wound or site care, and rotate IV sites as indicated. High glucose is an excellent medium for pathogens.

Provide catheter or perineal care and teach female patients to clean front to back. UTIs and vaginitis are more common in diabetes.

Provide meticulous skin care, gently massaging bony areas and keeping skin dry, with dry, wrinkle-free linens. Poor peripheral circulation raises the risk of breakdown.

Recommend vaccines as indicated. Streptococcus pneumoniae and influenza are the most common respiratory infections in diabetes, and patients are six times more likely to need hospitalization during influenza epidemics. Pneumococcal and influenza vaccines are recommended.

16. Preventing Diabetic Neuropathies

Neuropathy affects peripheral, autonomic, and spinal nerves. Sustained high glucose drives it, and control reduces its incidence. The mechanisms are vascular and metabolic: capillary basement membrane thickening, capillary closure, demyelination, and disrupted nerve conduction.

Nursing Diagnosis

• Risk for Peripheral Neurovascular Dysfunction as evidenced by impaired glucose metabolism, diminished sensory perception, and potential for foot injury or infection.

Expected Outcomes

• The patient demonstrates proper foot care, including daily inspection, moisturizing, and protective footwear.
• The patient shows improved mobility, balance, and proprioception without falls or injury.

Peripheral neuropathies

Peripheral neuropathy hits the distal nerves, mostly the lower extremities, usually symmetrically, and can move proximally.

Assess and document sensory and motor function, including paresthesias, burning, and numbness in the lower extremities. Neuropathy can be silent or present as paresthesias and numbness, with decreased proprioception, light touch, and an unsteady gait. Reduced pain and temperature sensation raises the risk of unnoticed foot injury and infection, and Charcot joints and foot deformities can develop. Exam shows decreased reflexes and vibratory sensation. Rule out other causes.

Teach optimal glucose control, which delays the onset and progression of neuropathy and reduces symptoms.

Teach foot care and hygiene: daily inspection, cleaning, moisturizing, and protection to prevent injury, infection, and deformity.

Give prescribed analgesics for neuropathic pain. First-line options include gabapentinoids, serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and sodium channel blockers.

Autonomic neuropathy

Management aims to relieve symptoms and modify risk factors.

Assess sensory and motor function in the lower extremities and perform regular neurologic checks (deep tendon reflexes, vibratory sensation, proprioception). Autonomic neuropathy affects cardiac, GI, renal, and sexual systems, producing tachycardia, orthostatic hypotension, delayed gastric emptying, diabetic constipation or diarrhea, urinary retention and neurogenic bladder, hypoglycemic unawareness, reduced sweating (sudomotor neuropathy), and sexual dysfunction.

Assess deep tendon reflexes to track neurologic status.

Provide education and support for sexual dysfunction, including erectile dysfunction in men and changes in women, with counseling and referral as needed.

Teach glucose management through insulin adherence and self-monitoring, which slows neuropathy progression.

Guide management of diabetic diarrhea (bulk-forming laxatives or antidiarrheals) and delayed gastric emptying (low-fat diet, small frequent meals, glucose monitoring, prokinetics). Manage constipation with a high-fiber diet, hydration, and medication when needed.

Connect the patient to physical and occupational therapy to improve balance, gait, and proprioception and reduce falls.

Teach daily foot inspection and self-care to prevent injury and infection. Keep feet clean, dry, and moisturized.

Teach protective footwear with cushioning and support to reduce trauma and pressure ulcers.

Monitor skin integrity, especially the feet, and turn and reposition to prevent pressure ulcers.

17. Diabetes Foot Care

Between 50% and 75% of lower-extremity amputations occur in patients with diabetes, and over 50% of these are preventable with proper foot care. Assessment, prevention, and teaching are the whole game here.

Teach proper foot care and daily practice: foot assessment, self-care, and risk-factor management. Patients with sensory loss, prior ulceration, or amputation get their feet inspected at every visit. Teach self-exam by palpation or visual inspection with an unbreakable mirror.

Perform foot assessments at visits, or at least once per year for high-risk patients. Include skin inspection, foot deformity assessment, neurologic assessment with monofilament and other sensory testing, and vascular assessment with leg and foot pulses.

Teach foot hygiene to prevent infection and breakdown. Preventive measures include:

• Daily inspection for cuts, blisters, red spots, and swelling.
• Washing with warm water, drying thoroughly (especially between the toes), and applying lotion without leaving moisture between the toes.
• Closed-toed, well-fitting shoes, with orthotics or custom shoes for specific needs.
• Trimming toenails straight across, avoiding sharp corners.
• Reducing risk factors such as smoking and elevated blood lipids.
• Avoiding high-risk behavior: walking barefoot, using heating pads, open-toed shoes, soaking the feet, or shaving calluses.
• Seeing a podiatrist for pressure areas, calluses, and toenail care.
• Avoiding home remedies and self-medication for foot problems.
• Keeping glucose controlled to improve resistance to infection and prevent neuropathy.

Have the patient wear closed-toed, well-fitting shoes for protection.

Teach straight-across toenail trimming, filing sharp corners to the contour of the toe. Refer patients with visual impairment or thickened toenails to a podiatrist.

Screen for peripheral artery disease (PAD): lower-extremity pulses, capillary refill, skin color changes with dependency and elevation, and venous filling time. Refer patients with leg fatigue, claudication, rest pain relieved by dependency, or decreased or absent pedal pulses for ankle-brachial index and further vascular workup.

Discuss reducing PAD risk factors such as smoking and elevated blood lipids to improve circulation and wound healing.

Advise against home remedies, over-the-counter agents, and self-medication for foot problems. Refer to the provider or podiatrist.

Stress glucose control to keep up resistance to infection and prevent neuropathy.

18. Providing Emotional Support Through Effective Coping

A new diagnosis can leave patients feeling they have no control. The relentless self-care wears on people and undercuts management. Acknowledge negative feelings, name strengths, correct misinformation, and steer toward problem-solving.

Assess how the patient has handled problems before and identify locus of control. Patients with an internal locus look for ways to control their own program; those with an external locus want to be cared for and may blame outside factors.

Acknowledge that the patient's reactions are normal. Diabetes management is a full-time job and a constant reminder of the disease.

Give the significant other (SO) a chance to express concerns and discuss how to help.

Encourage the patient and SO to express feelings about hospitalization and the disease.

Ask about the patient's and SO's expectations and goals. Unrealistic expectations or outside pressure breed frustration and loss of control.

Determine whether the relationship with the SO has shifted. The constant demands of management often change the focus of a relationship.

Support participation in self-care and give positive feedback, which builds a sense of control.

Assess family coping, dynamics, and expectations around long-term care, including the response of siblings, use of support systems, and any guilt, anxiety, overprotection, or overeating. A child with long-term needs can strain family relationships, and overprotection can harm growth and development.

Let family members and the child voice hard areas and anxiety and explore solutions.

Help the family set short- and long-term goals for the child and involve the child in family activities and care routines.

Encourage family members to express feelings and define which coping patterns help or hinder adjustment.

Bring in social workers, counselors, or clergy as needed.

Teach the family about long-term care and treatment.

Teach the family that overprotection can stunt growth and development, and to treat the child as normally as possible.

Stress the importance of followup appointments for exams and labs.

19. Promoting Self-Care and Hygiene

Hospitalization is a chance to watch and reinforce self-care. Observe insulin administration, glucose monitoring, and foot care rather than relying on what the patient tells you.

Assist with daily dental care. Diabetes raises the risk of periodontal disease.

Assess the oral cavity and skin carefully for dryness, cracks, breakdown, redness, and pressure points.

Keep skin clean and dry, especially where skin meets skin (groin, axilla, under the breasts), where chafing and fungal infection are common.

Prevent breakdown at pressure points, especially the heels. Sensory neuropathy hides the pain and pressure that would normally protect them.

Clean, dry, and lubricate the feet, except between the toes, and inspect them frequently.

Elevate the lower legs on a pillow in the supine position, heels over the edge, to offload the heels.

Position the feet to keep pressure off the heels when the patient is seated.

Give preventive care to the unaffected foot and specialized care to an affected foot with an ulcer.

Teach female patients measures to prevent vaginal infection, especially when glucose is high.

Stress daily personal hygiene during the hospital stay so the habit carries home.

Self-care and hygiene in older adults

Assess barriers to learning and self-care: decreased vision, hearing loss, memory deficits, and reduced mobility.

Give brief, simplified instructions with plenty of practice time.

Use assistive devices: a magnifier for insulin syringes, insulin pens, or mirrors for foot inspection.

20. Glycemic Control During Surgery

Surgical stress raises glucose through stress hormones. Frequent monitoring is the backbone of perioperative control.

Perform frequent glucose monitoring. Uncontrolled hyperglycemia during surgery causes osmotic diuresis with fluid and electrolyte loss, and type 1 patients risk ketoacidosis under stress.

Give IV insulin and dextrose as prescribed. Insulin controls glucose; dextrose prevents hypoglycemia and offsets the insulin.

Follow preoperative fasting guidelines to prevent highs and lows, especially if surgery is delayed after a morning dose of intermediate-acting insulin.

Monitor vital signs, including blood pressure, heart rate, and oxygen saturation, to catch complications early.

Assess level of consciousness and cognition. Altered LOC or cognition may signal hypo- or hyperglycemia needing immediate correction.

Protect the patient from injury: limit restraints when LOC is impaired, keep the bed low, and pad the bedrails if the patient is prone to seizures.

Monitor for wound infection and skin breakdown postoperatively. Impaired healing and reduced sensation raise the risk.
