1. Which laboratory value requires immediate action for a patient on
spironolactone?
• A. Sodium 135 mEq/L
• B. Potassium 5.8 mEq/L
• C. Chloride 100 mEq/L
• D. Glucose 110 mg/dL
Correct Answer: B
Rationale: Spironolactone is potassium-sparing. A potassium level of 5.8 mEq/L
indicates hyperkalemia, which can cause cardiac arrest.
2. A nurse is administering enoxaparin subcutaneously. Which technique is
correct?
• A. Expel air bubble before injection
• B. Massage site after injection
• C. Inject into abdomen, pinch skin, do not aspirate
• D. Rub vigorously to enhance absorption
Correct Answer: C
Rationale: Enoxaparin is given subcutaneously into the abdominal fold, with skin
pinched. Do not expel air bubble (it prevents leakage). Do not massage, as this causes
bruising.
3. A patient on amiodarone develops pulmonary fibrosis. Which assessment
finding supports this complication?
