1. A patient with heart failure is prescribed digoxin. Which
finding requires immediate nursing intervention?
• A) Apical pulse 58 bpm
• B) Serum potassium 4.0 mEq/L
• C) Digoxin level 1.2 ng/mL
,Page 2 of 156
• D) Weight gain of 1 lb in 24 hours
Correct Answer: A – Apical pulse <60 bpm is an indication
for holding digoxin due to risk of toxicity. Rationale: Digoxin
slows AV conduction; bradycardia increases risk of heart
block.
2. A patient on furosemide reports muscle cramps and
weakness. Which lab is most important to check?
• A) Sodium
• B) Potassium
• C) Calcium
• D) Magnesium
Correct Answer: B – Furosemide is a loop diuretic that causes
potassium wasting. Hypokalemia leads to muscle cramps,
weakness, and arrhythmias.
3. A patient taking warfarin has an INR of 4.5. There is no
bleeding. What should the nurse do first?
,Page 3 of 156
• A) Administer vitamin K
• B) Hold the next warfarin dose
• C) Give fresh frozen plasma
• D) Continue warfarin as ordered
Correct Answer: B – For INR 4.5 without bleeding, hold
warfarin; vitamin K is for higher INR or bleeding.
4. A patient on amiodarone develops pulmonary crackles and
dyspnea. What is the priority?
• A) Give furosemide
• B) Obtain chest x-ray
• C) Hold amiodarone and notify provider
• D) Increase oxygen
Correct Answer: C – Amiodarone can cause pulmonary
fibrosis; symptoms require immediate drug discontinuation.
5. A patient receives IV diltiazem for atrial fibrillation. BP
drops to 85/50. What is the priority?
, Page 4 of 156
• A) Stop the infusion
• B) Give IV fluids
• C) Administer atropine
• D) Continue infusion and monitor
Correct Answer: A – Diltiazem (calcium channel blocker)
causes hypotension; stop infusion first.
6. A patient on clopidogrel is scheduled for colonoscopy.
When should the drug be stopped?
• A) 24 hours before
• B) 5–7 days before
• C) 12 hours before
• D) Day of procedure
Correct Answer: B – Clopidogrel (antiplatelet) should be held
