What to do first
1. Check blood pressure and symptoms of dizziness or syncope.
2. Ask about face, lip, tongue, or throat swelling.
3. Review potassium, creatinine, pregnancy status, and potassium-containing supplements or salt substitutes.
ACE Inhibitors NCLEX Priority Sheet
ACE inhibitor questions test cough, angioedema, hyperkalemia, renal function, blood pressure, pregnancy risk, and interactions with potassium supplements or potassium-sparing drugs.
Study aid - not medical advice. Not a clinical decision tool. For NCLEX pharmacology review only.
Hold If
Notify the provider and follow protocol for angioedema symptoms, pregnancy, severe hypotension, hyperkalemia, acute kidney function worsening, or inability to breathe/swallow normally.
Angioedema is an emergency clue, not a routine side effect.
Labs to Watch
Watch K+, BUN, creatinine, eGFR, and blood pressure.
ACE inhibitors can increase potassium and creatinine. Current clinical interpretation depends on baseline kidney disease, indication, and provider plan.

NCLEX Review Notes
Suffix Rule
NCLEX memory rule: ACE inhibitors often end in -pril, such as lisinopril, enalapril, and captopril.
Common side effect: dry cough.
Emergency side effect: angioedema.
Common side effect: dry cough.
Emergency side effect: angioedema.
NCLEX Trap
Trap: a patient taking lisinopril reports tongue swelling and trouble breathing, and the option says schedule a routine visit.
Safer answer: treat as possible angioedema, stop/hold per protocol, seek emergency help, and notify the provider.
Safer answer: treat as possible angioedema, stop/hold per protocol, seek emergency help, and notify the provider.
Related Pattern
ACE inhibitor vs loop diuretic: ACE inhibitors can raise K+; loop diuretics can lower K+.
Potassium caution: avoid potassium supplements or salt substitutes unless specifically directed.
Potassium caution: avoid potassium supplements or salt substitutes unless specifically directed.
Mini Quiz
Question: A patient on lisinopril has K+ 5.8 mEq/L and reports muscle weakness. What is the priority?
Answer: hold per protocol, assess rhythm/symptoms, notify the provider, and anticipate ordered hyperkalemia management.
Answer: hold per protocol, assess rhythm/symptoms, notify the provider, and anticipate ordered hyperkalemia management.
