Heart Failure Nursing Care Plans: 12 Nursing Diagnosis

The heart failure patient lives or dies by trends, not single numbers. A 3-pound overnight weight gain, a new S3, crackles creeping up the lung fields, nocturia that wakes them four times: these are the early signals that the failing pump is losing ground. Your job is to catch decompensation before it becomes pulmonary edema, keep fluid and electrolytes in range, protect the patient from the side effects of the drugs that are keeping them alive, and teach hard enough that they do not bounce back through the door in two weeks. Education and vigilant monitoring are what move the needle on morbidity and mortality here.

What is Heart Failure?

Heart failure (HF), historically called congestive heart failure (CHF), is a clinical syndrome in which the heart cannot pump enough blood to meet the body's metabolic needs after structural or functional impairment of ventricular filling or ejection. It is not a disease in itself. It is the common endpoint of chronic hypertension, coronary artery disease, valvular disease, and other cardiac insults. Whatever the cause, pump failure produces hypoperfusion of tissues followed by pulmonary and systemic venous congestion. It is progressive and chronic, managed with significant lifestyle change and medical therapy.

Heart failure usually hits the left side first, and the side that fails drives the picture.

Left-sided heart failure backs blood up into the lungs: dyspnea on exertion, pulmonary congestion and crackles, a cough that starts dry and nonproductive, frothy sputum that may be blood-tinged, weak thready pulse, tachycardia, oliguria with nocturia, and fatigue from inadequate tissue perfusion.

Right-sided heart failure backs blood up into the body: peripheral and visceral congestion, lower-extremity edema, hepatomegaly, ascites, anorexia and nausea, weakness, and weight gain from fluid retention.

Nursing Care Plans and Management

Nursing Problem Priorities

1. Improve myocardial contractility and perfusion. Support the pump with medications, vital-sign monitoring, and fluid balance so organs stay perfused.
2. Manage fluid volume. Track balance, watch for retention, give diuretics, weigh daily, and hold the line on a low-sodium diet.
3. Prevent complications. Stay ahead of pulmonary edema, arrhythmias, and thromboembolism.
4. Promote activity tolerance. Build toward 30 minutes of daily activity as tolerated, pace it, and prioritize.
5. Reduce anxiety. Comfort, psychological support, and concrete anxiety-management skills.
6. Minimize powerlessness. Pull the patient into decision-making.
7. Teach the disease and its prevention. Lifestyle change, medication adherence, and when to call for help.

Nursing Assessment

Assessment in heart failure is about tracking the response to treatment and the patient's adherence to self-management. Report worsening signs early so therapy can be adjusted, and address mood: heart failure is chronic, and depression and psychosocial distress travel with it.

Health history. Ask about dyspnea, shortness of breath, fatigue, and edema. Ask specifically about sleep interrupted by sudden shortness of breath. Explore what the patient understands about HF, what self-management strategies they use, and whether they can and will follow them.

Physical examination. Auscultate the lungs for crackles and wheezes and the heart for an S3. Check for jugular vein distention. Evaluate sensorium and level of consciousness. Assess dependent areas for perfusion and edema. Check the liver for hepatojugular reflux. Measure urine output to set a baseline for diuretic response, and weigh the patient daily.

Watch for tachycardia, ECG changes, BP swings (hypotension or hypertension), extra heart sounds (S3, S4), oliguria, diminished peripheral pulses, orthopnea, crackles, JVD, edema, chest pain, weakness, fatigue, dysrhythmias, dyspnea, pallor, diaphoresis, weight gain, respiratory distress, and abnormal breath sounds.

Common contributing factors include altered myocardial contractility and conduction, decreased cardiac output, structural defects (valvular disease, ventricular aneurysm), poor cardiac reserve, medication side effects, an oxygen supply-demand imbalance, prolonged bed rest and immobility, reduced glomerular filtration with increased ADH and sodium and water retention, diuretic use, invasive procedures, prolonged hospitalization, alveolar edema from elevated ventricular pressure, retained secretions, and the increased metabolic demand of a superimposed pneumonia.

Nursing Diagnosis

Formulate the diagnosis from your assessment and clinical judgment. Labels are a framework, not the point; in practice your judgment shapes the care plan to the patient in front of you. Common labels include Decreased Cardiac Output, Excess Fluid Volume, Impaired Gas Exchange, Ineffective Tissue Perfusion, Acute Pain, Activity Intolerance, Imbalanced Nutrition, Anxiety, and Risk for Ineffective Health Maintenance.

Nursing Goals

The patient will maintain adequate cardiac output (vital signs in acceptable range, dysrhythmias absent or controlled, no HF symptoms), engage in activities that reduce cardiac workload, meet self-care needs, maintain stable fluid volume (balanced I&O, clearing breath sounds, stable weight, no edema), verbalize their individual dietary and fluid restrictions, maintain skin integrity, manage pain, identify anxiety-reduction strategies, and participate actively in their treatment regimen.

1. Initiating Interventions for Decreased Cardiac Output

Cardiac output falls in heart failure because the muscle is too weak or too stiff to contract and relax normally. Catch the drop early and you can slow the disease and head off complications.

Auscultate the apical pulse and assess heart rate. Tachycardia is an early sign. A faster rate is the body's first attempt to compensate for low cardiac output, and it helps at first, but sustained tachycardia is harmful and worsens HF. Good rate control tracks with fewer hospitalizations and lower mortality.

Take a focused health history on HF symptoms and self-management. It tells you whether the patient is decompensating and whether they understand and follow their regimen.

Note heart sounds. An S3 (ventricular gallop) comes from a large volume of fluid hitting the ventricle in early diastole and is an early sign of rising ventricular volume and worsening HF. S1 and S2 may be soft from weak contraction. Murmurs may reflect valvular incompetence.

Assess rhythm and document dysrhythmias on telemetry. Both atrial and ventricular dysrhythmias are common. Myocardial stretch, fibrosis, and chamber dilation distort the conduction paths. Atrial fibrillation is the most common dysrhythmia in HF, rises with HF severity, and promotes atrial thrombus. Also watch for premature atrial contractions, paroxysmal atrial tachycardia, PVCs, multifocal atrial tachycardia, ventricular tachycardia, and ventricular fibrillation.

Assess for palpitations or an irregular heartbeat. Patients may report a fast or irregular beat from dysrhythmias or from a failing heart speeding up to compensate for low flow.

Palpate peripheral pulses. Low output shows as diminished radial, popliteal, dorsalis pedis, and posterior tibial pulses. Marked diminution or absence can mean severely depressed stroke volume or occlusive vascular disease. Pulsus alternans (a strong beat alternating with a weak one) may be present. Cool, pale, or cyanotic skin with weak pulses points to low output.

Monitor blood pressure. In acute HF, BP may be elevated from increased systemic vascular resistance and guides therapy (vasodilators, vasopressors). In chronic HF, BP gauges whether pharmacologic therapy is adequate or excessive.

Inspect the skin for mottling, pallor, and cyanosis. Low output drops perfusion to the extremities and can produce mottling, a blue-gray skin coloring. Increased tissue oxygen extraction in chronic HF can make the skin look dusky. Cool, clammy, pale skin signals hypoperfusion and helps the provider choose pharmacotherapy.

Monitor urine output, noting decreasing volume and concentrated urine. Reduced renal perfusion makes the kidneys retain sodium and water, and patients may grow resistant to diuretics. Output is often low during the day as fluid shifts into tissues and rises at night (nocturia) when supine positioning improves renal perfusion.

Note changes in sensorium: lethargy, confusion, disorientation, anxiety, depression. Cerebral hypoperfusion from low output and brain hypoxia shows as confusion, forgetfulness, or restlessness. Depression is 4 to 5 times more common in HF patients and carries a twofold risk of mortality and higher readmission rates. Assess level of consciousness for any decline in cerebral perfusion.

Examine the lower extremities for edema and rate its severity. Edema is a core HF finding and guides diuretic and fluid management.

Assess the abdomen for tenderness, hepatomegaly, and ascites. These point to hepatic congestion and guide treatment.

Assess jugular vein distention. JVD estimates central venous pressure and flags right ventricular failure. Distention greater than 4 cm above the sternal angle suggests elevated venous pressure.

Monitor labs and diagnostics. HF signs are nonspecific and mimic other conditions. The goal is to find the underlying cause and gauge the response to treatment.

Monitor oxygen saturation and ABGs, and give oxygen as indicated. Baseline saturation helps establish the diagnosis and severity in acute settings and reflects the heart's ability to perfuse tissue. Supplemental oxygen raises myocardial oxygen availability and relieves hypoxemia, ischemia, and activity intolerance; titrate to the degree of congestion and hypoxia, and use continuous pulse oximetry to track need and effect.

Provide a restful environment and protect rest and sleep. Cutting controllable stressors reduces cardiac workload and oxygen demand. The degree of rest depends on severity: severe HF may need bed rest, while mild to moderate HF can stay ambulatory with limited activity. During acute or refractory HF, enforce physical rest to improve contraction efficiency and cut myocardial oxygen demand and workload.

Provide a quiet environment and address emotional stress. Explain the plan, help the patient avoid stressful situations, and respond to their feelings. Psychological rest reduces the vasoconstriction, BP, and heart-rate rise that emotional stress drives.

Position in high Fowler's. This improves chest expansion and pulmonary capacity, reduces venous return, relieves pulmonary congestion, and eases pressure on the diaphragm. It also helps the chronic nonproductive cough that worsens when recumbent.

Check for calf tenderness, diminished pedal pulses, swelling, redness, or pallor. Bed rest, low output, and venous pooling raise the risk of thrombophlebitis.

Elevate the legs, avoiding pressure behind the knee. This decreases venous return and preload and may reduce thrombus or embolus formation.

Reposition every 2 hours. Prolonged immobility deconditions the patient and raises pressure-ulcer risk, especially over edematous skin where circulation is already poor.

Provide a bedside commode and stool softeners, and avoid the Valsalva maneuver. A commode is less work than reaching the bathroom or struggling with a bedpan. HF patients have autonomic dysfunction, and straining during defecation or breath-holding during position changes drops mean arterial pressure and cerebral blood flow, leaving them open to hypoperfusion, ischemia, and stroke.

Encourage active and passive exercise and increase activity as tolerated. Outside of acute HF, when temporary bed rest may be indicated, aim for 30 minutes of physical activity daily.

Withhold digitalis as indicated and report marked changes in rate, rhythm, or signs of toxicity. Toxicity is common (incidence around 20%) because of the narrow margin between therapeutic and toxic ranges. Digoxin may have to be held with toxic levels, a slow heart rate, or low potassium.

Give IV solutions cautiously, restricting total volume, and avoid saline. With elevated left ventricular pressure, the patient may not tolerate added preload, so monitor administered fluid closely. HF patients also excrete less sodium, which drives retention and cardiac workload.

Monitor for fluid and electrolyte imbalances. Fluid shifts and diuretics can cause excessive diuresis and hypokalemia (ventricular dysrhythmias, hypotension, generalized weakness). Hyperkalemia can occur with ACE inhibitors, ARBs, or spironolactone.

Monitor serial ECG and chest x-ray. ST-segment depression and T-wave flattening can develop from increased myocardial oxygen demand even without coronary artery disease. The film may show an enlarged heart and pulmonary congestion.

Measure cardiac output and functional parameters as indicated. Cardiac index, preload, afterload, contractility, and cardiac work can be measured noninvasively with thoracic electrical bioimpedance, useful for judging response to therapy and activity.

2. Monitoring Diagnostic Procedures and Laboratory Studies

These studies establish severity, track progress, and guide treatment.

BUN and creatinine. Elevation reflects decreased renal perfusion from HF or medications (diuretics, ACE inhibitors). Serum creatinine and BUN are also the standard markers for kidney function, which is commonly impaired in HF and affects drug choice and dosing.

Liver function studies (AST, LDH). May reveal hepatic congestion and signal the need for smaller medication doses.

PT and aPTT. Identify patients at risk for excessive clotting and track anticoagulant effect.

Atrial natriuretic peptide (ANP). Secreted by right atrial cells when pressure rises; elevated in HF.

B-type natriuretic peptide (BNP). Secreted by the ventricles in response to volume and fluid overload; rises as HF symptoms worsen.

Electrocardiogram (ECG). Can point to the underlying cause; ST-segment depression and T-wave flattening can appear from increased myocardial oxygen demand even without coronary artery disease.

Echocardiogram. Shows chamber size and thickness, contraction strength, and ejection fraction (the percentage of blood pumped with each beat). Repeated over time to track cardiac function.

Cardiac stress test. Evaluates the heart's response to exertion or pharmacologic stress, assesses exercise capacity, and uncovers exercise-induced arrhythmias or coronary blockages.

Complete blood count (CBC). Identifies anemia, infection, or other abnormalities that affect HF management.

Electrolyte levels. Sodium, potassium, and magnesium imbalances affect rhythm and cardiac function.

Chest x-ray. May show an enlarged heart and pulmonary congestion.

3. Administering Medication and Pharmacological Interventions

Medications manage symptoms, improve heart function, prevent complications, and extend survival.

Diuretics. First-line for any patient with volume overload. They cut blood volume and lower venous pressure, arterial pressure, pulmonary and peripheral edema, and cardiac dilation. Conventional diuretics reduce the risk of death and worsening heart failure versus placebo in CHF (about 80 deaths avoided per 1,000 people treated) and improve exercise capacity by roughly 28% to 33% over other active drugs.

Diuretic type	Examples	Mechanism	Use in heart failure	Adverse effects
Thiazide	Hydrochlorothiazide (Microzide)	Inhibits sodium reabsorption in the distal convoluted tubule, promoting sodium and water excretion	Long-term therapy in moderate edema; effective when GFR is adequate	Hypokalemia (raises risk of digoxin-induced dysrhythmias); ineffective in low GFR and severely reduced cardiac output
Loop	Furosemide (Lasix), ethacrynic acid (Edecrin)	Inhibits the Na-K-2Cl cotransporter in the ascending loop of Henle, producing significant diuresis	Preferred for severe HF; effective even in low GFR	Hypokalemia, severe hypotension from excessive fluid loss; reduces alveolar congestion and improves gas exchange
Potassium-sparing	Spironolactone (Aldactone)	Antagonizes aldosterone receptors in the collecting ducts, reducing sodium reabsorption and potassium excretion	Counters potassium loss from thiazide and loop diuretics; reduces risk of digoxin-induced dysrhythmias	Hyperkalemia (principal adverse effect)

Nursing actions for diuretics: document fluid intake and output with daily weights, since weight change is an early marker of fluid shifts. Monitor serum potassium regularly; loop and thiazide diuretics drive potassium loss and hypokalemia. Teach the low-sodium diet and fluid restriction, which reduce overload and the need for diuretics. Assess for orthostatic hypotension and kidney injury. With aldosterone antagonists like spironolactone, monitor serum creatinine and potassium closely during initiation for renal impairment or hyperkalemia. Evaluate the response and watch for worsening cardiorenal syndrome.

Vasodilators, arterial dilators, and combinations. These raise cardiac output, reduce circulating volume, and lower systemic vascular resistance, cutting ventricular workload.

• Isosorbide dinitrate (ISDN) (Nitro-Dur, Isordil) selectively dilates veins; in severe refractory HF it reduces congestive symptoms and improves exercise capacity. Watch for orthostatic hypotension and reflex tachycardia.
• Hydralazine (Apresoline) selectively dilates arterioles and improves cardiac output and renal blood flow. It is always paired with ISDN (for example, BiDil, a fixed-dose combination of hydralazine and ISDN).
• Nitroglycerin given IV is a powerful vasodilator that sharply reduces venous pressure and relieves acute severe pulmonary edema. Main adverse effects are hypotension and reflex tachycardia.
• Sodium nitroprusside (Nitropress) rapidly dilates arterioles and veins, reducing afterload (raising cardiac output) and venous pressure (relieving congestion). Monitor BP continuously.
• Nesiritide produces rapid balanced vasodilation, dropping right and left ventricular filling pressures and systemic vascular resistance while raising stroke volume and cardiac output without changing heart rate.

ACE inhibitors (benazepril, captopril, lisinopril, enalapril, quinapril, ramipril, moexipril) block the renin-angiotensin-aldosterone system by inhibiting conversion of angiotensin I to angiotensin II. They reduce mortality, morbidity, hospitalizations, and symptoms, improve hemodynamics, and favorably alter cardiac remodeling. Watch for symptomatic hypotension, hyperkalemia, cough, and worsening renal function. Nursing actions: monitor BP before and after dosing (these promote vasodilation and can drop pressure), monitor serum potassium for hyperkalemia (worse with concurrent diuretics), teach adherence and the importance of followup, assess for a dry persistent cough (a common side effect that can also signal worsening ventricular function), and watch for angioedema (face, lip, or throat swelling), which is rare but life-threatening and requires immediate discontinuation and emergency care.

ARBs (eprosartan, irbesartan, valsartan) are for patients who cannot tolerate ACE inhibitors, usually because of cough. They block angiotensin II at its receptor, reduce afterload, improve LV ejection fraction, cut symptoms and hospitalizations, raise exercise tolerance, and lower mortality. Monitoring matches ACE inhibitors.

Cardiac glycosides (digoxin, Lanoxin). Digoxin increases myocardial contractile force (positive inotropy), raising cardiac output, and slows AV node conduction. It does not lower mortality but prevents readmission and reduces symptoms of systolic HF, and is now a second-line agent. Monitor renal function and serum potassium to adjust dose and prevent toxicity. Assess and document signs of toxicity: anorexia, nausea, visual disturbances, confusion, and bradycardia. Draw serum digoxin levels if renal function changes or toxicity is suspected, and teach the patient the toxicity signs and the need for adherence and prompt reporting.

Inotropic agents (milrinone (Primacor), dobutamine (Dobutrex), amrinone, vesnarinone) are for short-term treatment of HF that does not respond to glycosides, vasodilators, and diuretics. Given IV, they increase contractility and produce vasodilation, and have reduced mortality by 50% while improving quality of life. Nursing actions: give IV milrinone or dobutamine to hospitalized patients with acute decompensated HF who fail routine therapy. Milrinone promotes vasodilation and can cause hypotension, so monitor BP closely before and during infusion, especially in hypovolemic patients, and monitor BP, ECG, and rhythm during and after infusion for hypotension and ventricular dysrhythmias. Dobutamine stimulates beta-1 receptors to raise contractility and renal perfusion but can raise heart rate and trigger ectopy and tachydysrhythmias, so monitor rate and rhythm closely. Document hemodynamic data with all IV inotropes, vasodilators, and diuretics, and assess the need for continuous home inotropic therapy in patients who cannot be weaned and have end-stage HF.

Beta-blockers (carvedilol (Coreg), bisoprolol (Zebeta), metoprolol (Lopressor)) are first-line. They blunt sympathetic overdrive, producing vasodilation, lower BP, reduced afterload, and reduced cardiac workload. They improve functional status, reduce mortality and morbidity, raise LV ejection fraction and exercise tolerance, slow HF progression, and prolong survival. Watch for worsening HF symptoms, hypotension, fatigue, and bradycardia. Nursing actions: monitor BP and heart rate before and after dosing. Teach that the dose is started low and titrated up over weeks and that therapeutic effects are delayed. Document the response and side effects (dizziness, hypotension, bradycardia, fatigue, depression), which are most common in the early weeks; reassure the patient these often settle. Assess respiratory status in patients with bronchospastic disease such as uncontrolled asthma, since beta-blockers can cause bronchoconstriction, and report significant cardiovascular or respiratory changes.

Morphine sulfate. Decreases vascular resistance and venous return, lowering myocardial workload, especially with pulmonary congestion. Reserve it for myocardial ischemia refractory to drugs that improve oxygen supply and demand, and do not use it for chest pain that has not first been treated with nitrates and beta-blockers. It also eases anxiety and breaks the anxiety-catecholamine cycle.

Antianxiety agents and sedatives. Promote rest, reducing oxygen demand and myocardial workload. HF patients are often restless and anxious and overwhelmed by breathlessness; emotional stress activates the sympathetic nervous system and raises cardiac workload, so reducing anxiety reduces the load. HF also carries a high rate of depression, which is linked to increased morbidity and mortality.

Anticoagulants (low-dose heparin, warfarin (Coumadin)). For patients with atrial fibrillation or a thromboembolic history, given prophylactically against thrombus and embolus in the setting of venous stasis, bed rest, dysrhythmias, and prior clots. Monitor INR and PT to keep the patient in the therapeutic range and minimize bleeding or clotting.

Bronchodilators (aminophylline). Increases oxygen delivery by dilating small airways and has a mild diuretic effect that helps reduce pulmonary congestion.

4. Maintaining or Improving Respiratory Function

As HF progresses, fluid backs up into the lungs, compromising gas exchange and breathing.

Assess respiratory rate, accessory muscle use, air hunger, lung excursion, cyanosis, and vital-sign changes. These are warning signs of rising respiratory distress that need immediate attention.

Auscultate breath sounds for crackles and wheezes. Crackles mean edematous airways and alveoli popping open; wheezes suggest bronchospasm with congestion. Decreased sounds can mean fluid overload or altered ventilation.

Monitor oxygen saturation and ABGs. A pulse oximetry value of 92% or less, decreased PaO2, and increased PaCO2 signal worsening oxygenation. Pulse oximetry can read up to 7% higher than actual saturation in patients with abnormal cardiac index, so confirm with ABGs when the picture does not fit.

Observe skin, mucous membranes, and nail beds for peripheral cyanosis. Cyanosis of the nail beds may reflect vasoconstriction or a response to fever or chills.

Monitor potassium. Hypokalemia is likely in patients on diuretics.

Instruct in effective coughing and deep breathing, and encourage frequent position changes. Clears the airway, improves oxygen delivery, and helps prevent atelectasis and pneumonia.

Position in high Fowler's with the head of the bed up to 90 degrees. Promotes maximal inspiration and expectoration.

Suction secretions as needed to clear an obstructed airway.

Administer supplemental oxygen as indicated. For acute decompensated HF, give high-flow oxygen via nonrebreather mask, positive airway pressure, or intubation and mechanical ventilation; as the patient improves, titrate to keep saturation above 92%.

Assist with relaxation techniques to reduce muscle tension and the work of breathing.

5. Managing Fluid Volume and Electrolyte Imbalance

Track fluid status with lung auscultation, daily weights, and low-sodium adherence. Severe HF often needs IV diuretics; milder symptoms are managed with oral diuretics. A single diuretic dose can move a large volume of fluid within hours.

Monitor urine output: amount, color, and timing of diuresis. Output is often scant and concentrated during the day from reduced renal perfusion and increases at night or with bed rest, when recumbency favors diuresis. Oliguria or anuria may signal renal dysfunction.

Calculate 24-hour intake and output. In patients on IV fluids and medications, watch intake closely; ask the provider or pharmacist whether medications can be double-concentrated to cut fluid volume. Diuretics can produce a sudden loss that leaves the patient circulating-hypovolemic even while edema or ascites persists.

Maintain chair or bed rest in semi-Fowler's during the acute phase. Elevating the head of the bed, adding pillows, or using a recliner reduces venous return, relieves pulmonary congestion, and eases diaphragmatic pressure. Supporting the lower arms on pillows relieves shoulder strain.

Set a fluid-intake schedule if fluids are restricted, building in beverage preferences. Give frequent mouth care; ice chips count toward the allotment. Involving the patient improves their sense of control and cooperation.

Weigh daily and monitor BUN, creatinine, and serum potassium, sodium, chloride, and magnesium. A weight gain of 5 pounds is roughly 2 liters of retained fluid; diuresis can swing it the other way. Build the fluid plan with the patient so it fits prescribed limits and their preferences.

Assess for distended neck and peripheral vessels and check dependent areas for pitting edema; note generalized edema (anasarca). Peripheral edema starts in the feet and ankles and ascends as failure worsens. Pitting edema is usually obvious only after at least 10 pounds of retained fluid.

Auscultate breath sounds for adventitious sounds and note dyspnea, tachypnea, orthopnea, paroxysmal nocturnal dyspnea, and persistent cough. Left-sided congestion tends to present acutely; right-sided respiratory symptoms build more gradually and are harder to relieve.

Investigate sudden extreme dyspnea, air hunger, a need to sit straight up, a sensation of suffocation, or panic. This can mean acute pulmonary edema or embolus and, unlike orthopnea or PND, develops rapidly and needs immediate intervention.

Give oral diuretics in the morning. Morning dosing avoids interrupting nighttime rest and reduces nocturia, urgency, and incontinence, which matters most in older patients.

Promote a low-sodium diet. Teach label reading and avoidance of canned, processed, and convenience foods. Sodium restriction limits retention and cardiac workload.

Assess for and prevent pressure ulcers. Edematous skin has poor circulation and breaks down faster; reposition and offload pressure routinely.

Monitor BP and central venous pressure. Hypertension and elevated CVP suggest fluid volume excess and developing congestion.

Assess bowel sounds and note anorexia, nausea, abdominal distension, and constipation. Visceral congestion in progressive HF alters intestinal function.

Measure abdominal girth as indicated. In progressive right-sided failure, fluid shifts into the peritoneal space and girth increases (ascites).

Palpate the abdomen and note right-upper-quadrant pain and tenderness. Venous congestion produces hepatomegaly and pain, alters liver function, and prolongs drug metabolism.

Provide small, frequent, easily digestible meals. Reduced gastric motility impairs digestion; small meals ease discomfort.

Maintain fluid and sodium restrictions and consult a dietitian. Restriction reduces total body water and prevents reaccumulation; the dietitian helps meet caloric needs within the sodium limit.

Assist with ultrafiltration, dialysis, or mechanical fluid removal as indicated. Though not used often, these rapidly reduce circulating volume in pulmonary edema refractory to other therapies.

6. Providing Perioperative and Device Support

Several procedures and devices treat heart failure or support the failing pump. Across all of them, monitor vital signs and cardiac function, manage pain, watch for bleeding and infection, support deep breathing and coughing, and teach wound care and activity restrictions.

Coronary artery bypass graft (CABG). Creates a new path around blocked or narrowed coronary arteries.

Heart valve replacement. Replaces a damaged valve with a prosthetic; add medications to prevent clots and monitor anticoagulation.

Angioplasty. A minimally invasive procedure that opens a blocked or narrowed vessel with a balloon-tipped catheter. Obtain informed consent, prepare the patient physically and emotionally, monitor vital signs throughout, and teach post-procedure wound care, activity restrictions, and medications.

Cardiomyoplasty. An experimental procedure wrapping the latissimus dorsi around the heart and stimulating it to contract with each beat, used to augment ventricular function while awaiting transplant. Benefits are limited and it is usually not recommended.

Transmyocardial revascularization. Uses a CO2 laser to create multiple 1-mm channels in viable but underperfused myocardium.

Pacemaker. May be placed to correct bradydysrhythmias unresponsive to drugs, which can aggravate failure and produce pulmonary edema.

Ventricular assist device (VAD). A battery-powered pump positioned between the cardiac apex and the descending thoracic or abdominal aorta. It receives blood from the left ventricle and ejects it into the systemic circulation, often letting the patient resume a near-normal life while awaiting recovery, transplant, or a decision.

Intra-aortic balloon pump (IABP). Temporary support for the failing heart in a critically ill patient with potentially reversible HF. It demands continual assessment and expert knowledge of the cardiovascular system, the device's effects, and its adverse events. With end-stage HF, cardiac transplantation may be indicated.

7. Managing Acute Pain and Discomfort

Acute pain in HF can come from angina (reduced coronary flow), musculoskeletal strain, or complications such as pleural effusion or edema.

Assess pain intensity with a rating scale, plus location and precipitating factors. This supports accurate diagnosis.

Monitor vital signs, especially pulse and BP, every 5 minutes until pain subsides. Tachycardia and elevated BP accompany angina and reflect sympathetic compensation.

Assess the response to medications every 5 minutes to judge effectiveness and the need for more intervention.

Give or assist with vasodilators as ordered. Nitroglycerin enhances myocardial blood flow and reduces venous return, lowering preload and workload.

Provide comfort measures and a quiet environment. Nonpharmacologic pain relief, and a quiet room reduces energy demand.

Elevate the head of the bed to improve chest expansion and oxygenation.

Teach relaxation techniques. Anginal pain is often triggered by emotional stress that relaxation can relieve.

Teach the patient to distinguish angina from a myocardial infarction. Some chest pain is more serious than stable angina; the patient needs to recognize the difference to seek emergency care in time.

8. Promoting Adequate Cardiac Tissue Perfusion

Perfusion is the whole game. Inadequate perfusion drives fatigue, dizziness, reduced exercise tolerance, organ dysfunction, and impaired healing. Catch falling perfusion before an organ is injured.

Monitor vital signs, especially pulse and BP, every 15 minutes (or more often if unstable). Watch for any drop greater than 20 mm Hg below baseline or related changes such as dizziness or altered mental status. Hypotension is a major effect of HF management and of the disease itself.

Assess the extremities for color, temperature, capillary refill, and pulse amplitude. Peripheral vasoconstriction from sympathetic compensation produces pallor, coolness, capillary refill longer than 2 seconds, and weak pulses; edema may be present from overload.

Assess overall cardiac and circulatory status to establish a baseline and detect changes in output or perfusion.

Assess mental status for anxiety, memory loss, confusion, depression, restlessness, lethargy, stupor, or coma. These can signal reduced cerebral perfusion and oxygenation.

Review cardiac markers (CK, CK-MB, total LDH, LDH-1, LDH-2, troponin, myoglobin). These rise at different times after myocardial infarction and help rule MI in or out as the cause of chest pain.

Monitor cardiac rhythm and the 12-lead ECG for tracings that indicate ischemia.

Give vasodilators and beta-blockers as ordered. Nitroglycerin enhances myocardial blood flow and lowers preload and workload; beta-blockers reduce myocardial oxygen consumption and prevent further angina.

Provide oxygen and monitor saturation. Raising circulating oxygen increases delivery to the myocardium, reducing ischemia and pain.

Reposition every 2 hours to prevent pressure injury, and offer small, frequent feedings to limit heartburn and indigestion.

9. Promoting Nutritional Balance and Low-Sodium Adherence

Assess the patient's ability to follow the sodium restriction, and account for preferences, cultural food patterns, and nutritional needs. A personalized plan strikes a workable balance between restriction and adherence while keeping nutrition adequate.

Teach the low-sodium diet, typically no more than 2 g/day, to reduce fluid retention and congestion. Sodium restriction supports fluid balance and decreases myocardial workload.

Monitor adherence and assess for dietary indiscretions that can sharply worsen symptoms and drive readmission.

Involve family in supporting the diet. Adherence improves when family members follow the diet too.

Collaborate with a dietitian for balanced, individualized nutritional guidance.

Evaluate the response: symptom resolution, weight management, and overall improvement in HF status.

10. Maintaining Skin Integrity and Preventing Pressure Ulcers

Impaired peripheral circulation, immobility, edema, and poor nutrition all gang up on the skin.

Inspect the skin, noting bony prominences, edema, altered circulation, obesity, or emaciation. These mark the skin as high-risk.

Check the fit of shoes and slippers and change as needed. Dependent edema makes footwear fit poorly and raises the risk of pressure and breakdown on the feet.

Encourage frequent position changes and active and passive range-of-motion exercises. Reduces pressure, improves circulation, and shortens the time any area is deprived of blood flow.

Provide frequent skin care and minimize contact with moisture and excretions. Excessive dryness or moisture damages skin and speeds breakdown.

Avoid the intramuscular route. Interstitial edema and poor circulation impede absorption and predispose to breakdown and infection.

Provide pressure-relieving surfaces (alternating-pressure or egg-crate mattress, heel and elbow protectors) to offload the skin and improve circulation. Gentle massage around (not directly on) reddened areas can improve blood flow; never massage a compromised area directly, since that can injure the tissue.

11. Managing Activity Intolerance and Fatigue

Reduced activity deconditions the HF patient and worsens symptoms, but exercise training improves functional capacity, reduces dyspnea, and raises quality of life. Temporary bed rest is appropriate during an acute exacerbation; otherwise, push for daily activity within the patient's limits.

Check vital signs before and immediately after activity, especially with vasodilators, diuretics, or beta-blockers. Orthostatic hypotension can follow from vasodilation, diuresis, or compromised pumping.

Document the cardiopulmonary response to activity: tachycardia, dysrhythmias, dyspnea, diaphoresis, pallor. A heart that cannot raise stroke volume answers activity with a jump in rate and oxygen demand, worsening weakness and fatigue.

Assess for other causes of fatigue (treatments, pain, medications). Beta-blockers, tranquilizers, and sedatives can all cause fatigue.

Identify factors that limit activity and motivation: age, pain, breathing problems, vision or hearing loss, functional decline. Fatigue affects both actual and perceived ability to participate.

Monitor the response to activity. The heart rate should return to baseline within 3 minutes after activity. Check vital signs and saturation before, during, and after activity in the hospital; at home, gauge the degree of fatigue afterward. Adjust intensity, duration, and frequency to the response, and refer to cardiac rehabilitation for newly diagnosed patients or those needing more support.

Consider the 6-minute walk test to gauge physical ability by measuring the distance walked over 6 minutes.

Help identify and overcome barriers to activity. For example, sitting while chopping or peeling vegetables conserves energy.

Encourage daily physical activity and build a personalized exercise schedule with the provider and patient that paces and prioritizes activities and balances them with rest.

Provide safety guidelines: start low and slow. Use low-impact activities like walking, include warm-up and cool-down, avoid extreme temperatures and humidity, wait 2 hours after meals before exercising, and confirm the patient can talk during activity. If they cannot talk, the intensity is too high.

Evaluate accelerating activity intolerance, which may signal worsening decompensation rather than overactivity. Risk during exercise rises with age, presence of heart disease, and exercise intensity.

Promote adherence to exercise training and refer to cardiac rehabilitation for supervised sessions, structure, and encouragement.

Assist with self-care as needed while encouraging independence within limits. Meeting needs while reducing workload, and involving the patient, builds a sense of control.

Pace care and provide rest before and after exertion (bathing, eating, exercise). Allow older patients extra time; they are more vulnerable to falls and injury.

Cluster nursing care to allow rest periods without undue myocardial stress.

Implement a graded cardiac rehabilitation program. A gradual increase in activity strengthens cardiac function under stress while avoiding excessive workload and oxygen consumption.

Adjust daily activities and stop any that cause undesired changes. Halt all activity if severe shortness of breath, pain, or dizziness develops, and teach the patient and family to recognize overexertion.

Encourage adequate rest and sleep in a calm, quiet environment, and reinforce daily or weekly progress to support motivation, morale, and wellbeing. Patients need both motivation and self-efficacy to become more active.

12. Reducing Anxiety, Fear, and Powerlessness

Anxiety in HF comes from both psychosocial pressures and the physiologic activation of neurohormones such as catecholamines. It is fed by fear of decompensation, role changes, and worry about the ability to function. Reducing it reduces cardiac workload.

Assess for restlessness and anxiety as possible signs of hypoxia from pulmonary congestion. Prompt recognition allows interventions that improve oxygenation.

Promote physical comfort and provide psychological support. A calm environment and comfort measures (letting the patient sit in a recliner) reduce anxiety. A family member's presence, pet visitation, or animal-assisted therapy can reassure.

Administer oxygen during acute anxiety, which reduces the work of breathing and increases comfort.

Validate the patient's anxiety directly ("Are you feeling anxious now?") and acknowledge their feelings, which communicates acceptance. Interact calmly; a calm approach lowers anxiety and cardiac work.

Encourage the patient to express fears and feelings and identify the coping measures they already use, which helps gauge what works.

Screen for depression. Symptoms of depression and anxiety are present in about one-third of HF patients, at markedly higher rates than the general population.

Help the patient name what triggers anxiety and develop new coping skills (relaxation, deep breathing, positive visualization, guided imagery, reassuring self-statements). Avoid unnecessary reassurance, which can increase worry, and eliminate sources of anxiety where possible.

Explain all activities and procedures in advance using plain language and calm, slow speech, and confirm understanding. Predictability reduces anxiety; preadmission education leaves patients with less distress and better coping.

Use simple, brief statements, since moderate to severe anxiety limits comprehension, and educate the patient and family on the symptoms of anxiety so they can intervene early.

For powerlessness: assess for contributing factors, apathy, hopelessness, and depression, and evaluate decision-making competence. Powerlessness is the sense of having lost control over one's own interests. Recognize routines done without the patient's consent that foster it, and appraise its impact on appearance, intake, hygiene, and sleep.

Give information thoughtfully. Too much can overwhelm and add to powerlessness; the right information lets a patient act in their own interest and can strengthen independence.

Provide decision-making opportunities with increasing frequency and significance, help the patient reexamine unrealistic negative perceptions, and separate what they can control from what they cannot. Avoid coercive approaches, which deepen powerlessness and erode self-esteem.

Eliminate unpredictability by preparing the patient for tests and procedures, support planning for increased future responsibility with realistic short-term goals, and provide home safety measures (alarm systems, shower and bathtub safety devices) when indicated.

13. Health Teaching and Patient Education

Treating heart failure means complex regimens and major lifestyle change for the patient and family. Readmissions are most often driven by noncompliance with diet, fluid restriction, and medications, and by poor care coordination and inadequate followup. This is where nurses prevent the bounce-back.

Explain normal heart function and how the patient's heart differs, and distinguish a heart attack from heart failure. Understanding the disease supports adherence.

Reinforce the treatment rationale and include the family, especially for complex regimens like home dobutamine infusion for patients who cannot be weaned or are awaiting transplant. Patients often alter the regimen when they feel well or feel poorly, which worsens symptoms. Home IV therapy requires committed caregivers to manage infusion pumps, PICC-line dressings, I&O, and HF signs.

Encourage a regular home exercise program and provide guidelines for sexual activity (sex in the morning when rested, patient on top, other physical expressions of affection), which preserves a satisfying relationship while managing exertion. Stress staying as active as possible without exhaustion, with rest between activities, since overexertion further weakens the heart.

Teach sodium limitation. Provide a list of high-sodium foods to avoid and limit, and encourage label reading. Dietary sodium greater than 3 grams per day can offset the effect of diuretics. The biggest sources are table salt and obviously salty foods, but canned soups, luncheon meats, and dairy can also run high.

Refer to a dietitian for counseling specific to the patient's dietary customs, especially with nausea, vomiting, or cardiac cachexia. Six small meals with liquid and vitamin supplements can limit inappropriate weight loss.

Review medications, purpose, and side effects with both oral and written instructions. Understanding the regimen and reporting side effects promptly prevents drug-related complications; written material lets patients refresh their memory later. Take the diuretic early in the morning to allow its effect before bedtime and protect sleep.

Teach and obtain a return demonstration of taking and recording daily pulse and BP, and when to notify the provider (rate or rhythm above or below preset parameters). This supports self-monitoring and early detection of problems such as digitalis toxicity.

Discuss controlling risk factors and aggravating factors: smoking (potentiates vasoconstriction), high-salt diet (promotes retention and edema), inactivity, overexertion, and temperature extremes (which can exhaust the patient, increase myocardial workload, and raise the risk of respiratory infection). Alcohol depresses cardiac contractility; limit it to social occasions or a maximum of 1 drink per day unless the cardiomyopathy is alcohol-induced, which requires complete abstinence.

Review the signs that require immediate attention: rapid significant weight gain, edema, shortness of breath, increased fatigue, cough, hemoptysis, and fever. A weight gain of more than 3 pounds in a week requires medical adjustment of diuretic therapy. The patient should weigh daily in the morning, without clothing, after voiding, and before eating.

Open time for questions and concerns. The chronic, debilitating nature of HF exhausts the patient's and family's coping and can lead to depression.

Teach infection avoidance: stay away from crowds and people with respiratory infections, get the yearly influenza vaccine, and get the one-time pneumonia vaccine. Circulatory compromise raises infection risk.

Stress reporting signs of digitalis toxicity: GI and visual disturbances, changes in pulse rate and rhythm, and worsening heart failure.

Identify community resources, support groups, and home health, and encourage outpatient cardiac rehabilitation, which helps with self-monitoring and home management as HF progresses.

Discuss advance directives and communicating plans to family and providers. Up to 50% of HF deaths are sudden, many at home, sometimes without significant worsening. If the patient refuses life-support measures, designate an alternative contact rather than 911 in the event of cardiac arrest.

Assess candidacy for advanced interventions. In underlying coronary artery disease, consider revascularization with PCI or CABG. For severe left ventricular dysfunction at high risk for life-threatening dysrhythmias, typically an ejection fraction less than 35% with NYHA class II or III, consider an implantable cardioverter defibrillator to prevent sudden death. For patients who do not respond to standard therapy and have a prolonged QRS with left bundle branch block, consider cardiac resynchronization therapy with a biventricular pacemaker to synchronize ventricular contraction, reduce mitral regurgitation, and improve output. For severe fluid overload resistant to diuretics, monitor ultrafiltration (output, BP, hemoglobin). For end-stage HF eligible for long-term survival, consider referral for cardiac transplantation.

Address the older adult specifically. Older patients on diuretics can develop bladder distention from prostatic obstruction, so monitor urinary frequency, urgency, and fullness and palpate or scan the suprapubic area. They may present atypically (weakness, somnolence rather than dyspnea), have reduced renal function that alters diuretic response, and have mobility limits that compound urinary problems.

Evaluation

Expected outcomes include tolerance for increased activity, maintained fluid balance, reduced anxiety, sound decision-making about care and treatment, and adherence to the self-care regimen.

Discharge and Home Care Guidelines

Teach the patient and family medication management, the low-sodium diet, activity and exercise recommendations, smoking cessation, and how to recognize worsening HF. Encourage questions so understanding is clear and complete. Discharge goals: cardiac output adequate for individual needs, complications prevented or resolved, an optimum level of activity and functioning attained, the disease process and regimen understood, and a plan in place to meet needs after discharge.

Documentation Guidelines

Document assessment findings, I&O and fluid balance, the degree of fluid retention, lab and diagnostic results, the response to interventions and teaching, and progress toward desired outcomes.
