🩺
📒 The 1-minute cheat sheet
📌 Types
Left → pulmonary congestion
Right → peripheral edema, JVD
🩺 Signs
Dyspnea, crackles, orthopnea
Pink frothy sputum = pulm edema
Weight gain, JVD, ↑ BNP
✅ Do
High Fowler's, O2, daily weight
Low Na+ diet, fluid restrict
Report > 2-3 lb/day gain
🧪 Meds
ACE/ARB, beta-block, diuretics
Digoxin, monitor K+ levels
📚 Heart Failure — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Heart failure is the heart's inability to pump enough blood to meet the body's needs. Left-sided failure backs blood up into the lungs (pulmonary congestion); right-sided failure backs blood up into the body (systemic/peripheral congestion). Memory aid: Left = Lungs, Right = Rest of body.
Right-sided: peripheral edema, jugular vein distention, weight gain, ascites, hepatomegaly
Daily weight is the most reliable indicator of fluid status (1 kg ≈ 1 L fluid)
Elevated BNP supports the diagnosis
✅
Nursing priorities
What to do, in order
Place in high-Fowler's position and give oxygen to ease dyspnea
Daily weights, strict I&O, low-sodium diet, fluid restriction as ordered
Give diuretics, ACE inhibitors/ARBs, and beta blockers as prescribed
Monitor potassium with loop diuretics; watch for digoxin response
🚩
Red flags — report now
Escalate immediately
Sudden weight gain > 2–3 lb in a day or 5 lb in a week — report it
Pink frothy sputum and severe dyspnea signal pulmonary edema — emergency
🧪
Labs & values
Numbers to know
BNP elevated in heart failure (> 100 pg/mL)
🗣️
Patient teaching
What patients must know
Weigh yourself daily at the same time and report rapid gains
Limit sodium; take medications even when feeling well
❓ Heart Failure: NCLEX FAQs
What are the priority nursing interventions for Heart Failure?
Place in high-Fowler's position and give oxygen to ease dyspnea. Daily weights, strict I&O, low-sodium diet, fluid restriction as ordered. Give diuretics, ACE inhibitors/ARBs, and beta blockers as prescribed. Monitor potassium with loop diuretics; watch for digoxin response.
What are the warning signs of Heart Failure a nurse must report?
Sudden weight gain > 2–3 lb in a day or 5 lb in a week — report it. Pink frothy sputum and severe dyspnea signal pulmonary edema — emergency.
What do I need to know about Heart Failure for the NCLEX?
Left-sided: dyspnea, orthopnea, crackles, pink frothy sputum, fatigue. Right-sided: peripheral edema, jugular vein distention, weight gain, ascites, hepatomegaly. Daily weight is the most reliable indicator of fluid status (1 kg ≈ 1 L fluid). Elevated BNP supports the diagnosis.
What patient teaching is important for Heart Failure?
Weigh yourself daily at the same time and report rapid gains. Limit sodium; take medications even when feeling well.
