5 Heart Failure Meds You Must Know For NCLEX
🧠EPISODE NOTES1. Furosemide (Lasix) – “The Diuretic Dynamo”
Mnemonic: “Furosemide flushes fluid fast but watch for falling potassium.”
Mechanism: Loop diuretic; blocks sodium & chloride reabsorption in the Loop of Henle.
Watch for:
Hypokalemia (↓ potassium → arrhythmia risk)
Hypotension, dehydration, ototoxicity (with rapid IV push)
Nursing actions:
Daily weights, strict I&O, monitor BP & labs.
Hold & notify provider if potassium critically low.
2. Carvedilol (Coreg) – “The Beta Blocker Boss”Mnemonic: “Carvedilol carves out congestion—but check pulse before blocking.”
Mechanism: Non-selective beta blocker with alpha-blocking → lowers HR & afterload.
Benefits: Reduces remodeling, improves survival in chronic HFREF.
Watch for:
Bradycardia, hypotension, bronchospasm (especially in asthma/COPD).
Nursing actions:
Check apical pulse for one full minute.
Hold if <50–60 bpm.
Never stop suddenly → rebound hypertension.
3. Spironolactone (Aldactone) – “The Potassium-Sparing Powerhouse”Mnemonic: “Spironolactone spares potassium but screen for swelling breasts.”
Mechanism: Aldosterone antagonist; reduces sodium reabsorption & prevents fibrosis.
Watch for:
Hyperkalemia (↑ potassium → peaked T-waves).
Endocrine side effects: gynecomastia, menstrual changes.
Nursing actions:
Monitor K+, BUN/Creatinine.
Avoid K+ supplements & salt substitutes.
4. Entresto (Sacubitril/Valsartan) – “The Dynamic Duo”Mnemonic: “Entresto enhances natriuresis but no ACE overlap.”
Mechanism:
Sacubitril: Inhibits neprilysin → ↑ beneficial natriuretic peptides.
Valsartan: ARB that blocks angiotensin II → ↓ vasoconstriction.
Key rule: 36-hour washout between ACE inhibitors & Entresto to prevent angioedema.
Watch for: Angioedema, hypotension, hyperkalemia.
Teaching: Report any facial or throat swelling immediately.
5. SGLT2 Inhibitors (Empagliflozin, Dapagliflozin) – “The Glucose Guardians”Mnemonic: “SGLT2 sweeps sugar and sodium but scrub for infections.”
Mechanism: Blocks sodium-glucose cotransporter 2 → promotes excretion of glucose & sodium.
Benefits: ↓ hospitalizations and mortality in both HFREF & HFpEF, even without diabetes.
Watch for:
Genital infections (yeast, UTI), dehydration, hypotension.
Nursing teaching:
Encourage hygiene & hydration; monitor urine changes.
đź©· Nursing PearlsDaily weights, potassium levels, BP, and heart rate are your best indicators.
Know when to hold and when to notify the provider.
Heart failure management is about balance: not too dry, not too wet, and always watching potassium.
đź“ť NCLEX Practice QuestionA patient on furosemide and spironolactone reports eating two bananas a day and using salt substitute.
Which lab result is most concerning?
A) Sodium 140
B) Potassium 6.1
C) Potassium 3.2
D) Calcium 9.5
Answer: B → Hyperkalemia risk due to spironolactone and potassium intake.
