1. A nurse is assessing a client with heart failure who reports
shortness of breath and 2+ pitting edema in the lower
extremities. Which of the following findings requires
immediate intervention?
A) Jugular vein distension
B) Weight gain of 1 kg in 24 hours
C) Crackles in the lung bases
D) Oxygen saturation of 88%
Answer: D) Oxygen saturation of 88%
Rationale: An O2 sat below 90% indicates hypoxemia and
requires immediate oxygen therapy. While JVD, crackles, and
weight gain are concerning, airway and breathing take priority.
2. A client is receiving digoxin 0.25 mg daily. Which finding
indicates toxicity?
A) Heart rate of 62 bpm
, B) Blurred yellow vision
C) Blood pressure 130/80 mmHg
D) Serum potassium 4.0 mEq/L
Answer: B) Blurred yellow vision
Rationale: Yellow or green halos around vision (xanthopsia) is a
classic sign of digoxin toxicity. Other signs include nausea,
vomiting, bradycardia, and arrhythmias.
3. A client post-cardiac catheterization has a femoral sheath
in place. Which action is most important?
A) Keep the affected leg straight
B) Apply heat to the insertion site
C) Ambulate with assistance
D) Encourage coughing and deep breathing
Answer: A) Keep the affected leg straight
Rationale: Keeping the leg straight prevents kinking of the sheath
and reduces bleeding risk. The leg should remain straight for 4–6
hours post-procedure.
4. A nurse is administering furosemide IV to a client with
heart failure. Which lab value should be monitored most
closely?
A) Sodium
, B) Potassium
C) Calcium
D) Magnesium
Answer: B) Potassium
Rationale: Furosemide is a loop diuretic that causes potassium
wasting. Hypokalemia can increase the risk of digoxin toxicity and
cardiac arrhythmias.
5. A client with angina reports chest pain rated 6/10. The
nurse administers nitroglycerin sublingually. After 5 minutes,
the pain is 5/10. What should the nurse do next?
A) Call the provider immediately
B) Administer a second dose
C) Administer morphine IV
D) Reassess in 15 minutes
Answer: B) Administer a second dose
Rationale: Nitroglycerin can be given every 5 minutes for up to 3
doses. If pain is not relieved after 3 doses, notify the provider.
6. A client is 1 day post-operative coronary artery bypass
graft (CABG). Which assessment finding requires immediate
action?
A) Temperature 100.4°F (38°C)
, B) Chest tube drainage 75 mL/hr
C) Jugular vein distension
D) Heart rate 110 bpm
Answer: C) Jugular vein distension
Rationale: JVD indicates possible cardiac tamponade or heart
failure post-CABG. This requires immediate provider notification.
7. A client with hypertension is started on lisinopril. Which
adverse effect should the nurse teach the client to report
immediately?
A) Dry cough
B) Swelling of the lips
C) Headache
D) Fatigue
Answer: B) Swelling of the lips
Rationale: Angioedema (swelling of lips, tongue, throat) is a life-
threatening allergic reaction to ACE inhibitors. The client should
seek emergency care.
8. A nurse is caring for a client with a pacemaker. Which ECG
finding indicates proper pacemaker function?
A) P wave before every QRS
B) Spike before every QRS complex
