Cardiovascular Drugs
1. A client is prescribed digoxin (Lanoxin) for heart failure.
Which finding indicates digoxin toxicity?
A. Heart rate of 72 bpm
B. Anorexia, nausea, and visual disturbances (yellow-green
halos)
C. Blood pressure 120/80 mm Hg
D. Serum digoxin level 1.0 ng/mL
Answer: B. Anorexia, nausea, and visual disturbances (yellow-
green halos)
Rationale: Early signs of digoxin toxicity include GI symptoms
(anorexia, nausea, vomiting) and visual changes (yellow-green
halos, blurred vision). Therapeutic digoxin level is 0.5–2.0
ng/mL.
,2. A client with atrial fibrillation is prescribed warfarin
(Coumadin). Which laboratory value indicates therapeutic
anticoagulation?
A. aPTT 60 seconds
B. INR 2.5
C. Platelet count 150,000/mm³
D. PT 12 seconds
Answer: B. INR 2.5
Rationale: For atrial fibrillation, therapeutic INR range is 2.0–
3.0. aPTT monitors heparin. PT alone is insufficient.
3. A client is receiving furosemide (Lasix) IV push. Which
electrolyte imbalance should the nurse monitor most
closely?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
Answer: B. Hypokalemia
Rationale: Furosemide is a loop diuretic that causes potassium
wasting. Hypokalemia increases risk of digoxin toxicity and
cardiac dysrhythmias.
,4. A client with hypertension is prescribed lisinopril
(Prinivil). Which adverse effect should the nurse report
immediately?
A. Dry cough
B. Angioedema (swelling of lips/tongue)
C. Dizziness
D. Fatigue
Answer: B. Angioedema (swelling of lips/tongue)
Rationale: Angioedema is a life-threatening allergic reaction to
ACE inhibitors. Dry cough is common but not emergent.
5. A client with angina is prescribed nitroglycerin
sublingual. Which instruction is correct?
A. Take one tablet every 5 minutes up to three doses for chest
pain. Call 911 if pain persists.
B. Swallow the tablet with a full glass of water.
C. Take the tablet at the first sign of chest pain and then wait 30
minutes before the next dose.
D. Store the tablets in a humid bathroom cabinet.
Answer: A. Take one tablet every 5 minutes up to three doses
for chest pain. Call 911 if pain persists.
Rationale: Standard dosing: one tablet sublingually or spray,
, may repeat every 5 minutes for up to 3 doses. Seek emergency
care if pain continues after 3 doses. Nitroglycerin should be
stored in a cool, dark, dry place.
6. A client on metoprolol (Lopressor) has a heart rate of 52
bpm and reports dizziness. What should the nurse do first?
A. Administer the medication as prescribed
B. Hold the dose and notify the healthcare provider
C. Increase the dose to raise the heart rate
D. Give atropine immediately
Answer: B. Hold the dose and notify the healthcare provider
Rationale: Beta-blockers should be held if heart rate <60 bpm
(or per protocol). The provider should be notified for possible
dose reduction.
7. A client is prescribed amiodarone (Cordarone). Which
baseline test is essential?
A. Pulmonary function tests
B. Thyroid function tests
C. Liver function tests
D. All of the above
