Nursing care plan for heart failure: priority diagnoses, interventions and rationales
Written and reviewed by Kevin Patel, MSN, RN, CCRN · 5 min read · Updated November 2026
Short answer
A nursing care plan for heart failure usually ranks impaired gas exchange first when the client is breathless lying flat or has crackles, then excess fluid volume, decreased cardiac output, activity intolerance and self-management teaching. The daily weight ties the plan together: it is the measurable cue for fluid volume and the core of discharge teaching.
Heart failure care plan table in priority order
These labels come from NANDA-I, the taxonomy most programs grade against. Rank them for a hypothetical adult admitted with worsening heart failure; a client who is comfortable at rest and only needs teaching would start lower down.
| Nursing diagnosis | Goal or outcome | Nursing interventions | Rationale |
|---|---|---|---|
| 1. Impaired gas exchange related to fluid in the lungs | Breathes without distress at rest and oxygen saturation stays at the prescribed target within 24 hours | Sit the client upright, give oxygen as prescribed, listen to lung sounds each assessment, report pink frothy sputum or breathlessness when lying flat at once | Fluid backing into the lungs causes breathlessness lying down and a cough with pink, foamy sputum |
| 2. Excess fluid volume related to sodium and water retention | Weight trends down toward the client's usual weight; edema decreases by discharge | Weigh every morning on the same scale before breakfast, keep strict intake and output, check edema, follow the prescribed sodium and fluid limits, watch response to diuretics | Weight change is the most objective early measure of fluid gained or lost |
| 3. Decreased cardiac output related to reduced pumping | Heart rate, rhythm, blood pressure and urine output stay within prescribed limits | Check apical pulse and blood pressure before cardiac medications and hold or report per protocol, track urine output, report new confusion or cool skin | Several heart failure drug classes lower heart rate or pressure, and poor output shows up as low urine and altered mentation |
| 4. Activity intolerance related to imbalance of oxygen supply and demand | Walks the hallway with rest stops and stable vital signs by day 3 | Space care, increase activity in steps, measure pulse and breathing before and after | Activity guidance is individual, so tolerance is measured rather than assumed |
| 5. Deficient knowledge related to home self-management | States weight limits to report and lists high-sodium foods to avoid before discharge | Teach daily weights and when to call, sodium limits, symptom diary, teach-back | Home weight gain and new symptoms are the early signals of decompensation |
Interventions describe what the nurse does and monitors. Starting or changing a diuretic is a provider decision, so the plan says give as prescribed and evaluate, which is also the part instructors expect to see written out.
Why breathing sits above fluid volume
Excess fluid is the underlying problem, but where that fluid sits decides urgency. Fluid in the lungs threatens oxygenation now, so impaired gas exchange goes first by the ABCs. Edema in the ankles is uncomfortable but not an immediate threat, so it lives in the fluid volume row.
Decreased cardiac output follows because it is the reason fluid builds up, and its cues (low urine output, cool skin, confusion) need prompt reporting. Students often swap rows two and three. Either can be defended when the cues back it, but writing decreased cardiac output with only edema as evidence is a mismatch instructors notice.
Assessment cues and the daily weight numbers
MedlinePlus lists the home warning signs: breathlessness when lying down or an hour or two after falling asleep, swelling in the feet, ankles or legs, needing to urinate at night, and a persistent cough with pink, foamy spit. The first and last point to the gas exchange row, swelling to fluid volume.
For the teaching row, MedlinePlus advises weighing every morning on the same scale after using the bathroom and before eating, in similar clothes, and calling the provider for a gain of more than 2 to 3 pounds in a day or 5 pounds in a week. It cites a sodium limit of 1,500 to 2,300 mg per day, though the client's own plan may differ. NHLBI lists diuretics, ACE inhibitors, ARBs, beta blockers, SGLT-2 inhibitors and digoxin among treatment classes, which is why pulse and pressure checks belong in row three.
Evaluating the plan with a worked example
Hypothetical example: a 66-year-old client gained 4 pounds in two days, sleeps on three pillows and has crackles at both bases. Diagnostic statement: impaired gas exchange related to alveolar fluid as evidenced by orthopnea, bibasilar crackles and a falling oxygen saturation on room air.
Evaluation checks each goal against data, not impressions. By day two the client lies at 30 degrees without breathlessness, crackles are limited to one base and weight is down 3 pounds: the gas exchange goal is partly met, so continue it. A goal written as client will feel better cannot be evaluated, which is the most common care-plan rewrite request.

MedlinePlus: Heart failure - fluids and diuretics. Daily weight method, call thresholds of 2 to 3 pounds in a day or 5 pounds in a week, sodium 1,500 to 2,300 mg per day, symptoms to report including orthopnea and pink foamy sputum.
NHLBI: Heart Failure Treatment. Medication classes used in heart failure, lowering sodium, and activity levels set individually with the provider.

Common questions
What is the priority nursing diagnosis for heart failure?
When the client has crackles, orthopnea or pink frothy sputum, impaired gas exchange is the priority because the airway and breathing come first. Without lung signs, excess fluid volume or decreased cardiac output usually leads, depending on which cues the assessment shows.
What are SMART goals for a patient with heart failure?
Goals should be specific, measurable and dated: for example, client weighs themselves each morning and states the 2 to 3 pound daily gain to report by discharge, or walks 50 feet with one rest stop and no breathlessness by day 3.
What are nursing interventions for heart failure?
Position upright, give oxygen as prescribed, assess lung sounds and edema, weigh daily on the same scale, record intake and output, check pulse and pressure before cardiac medications, space activity, and teach weight monitoring and sodium limits with teach-back.
