1. A client with heart failure is prescribed furosemide 40 mg
IV push. Which assessment finding requires immediate
action?
A. Weight increase of 1 lb in 24 hours
B. Serum potassium 3.2 mEq/L
C. Urine output 30 mL/hr
D. Blood pressure 130/80 mmHg
Correct Answer: B. Serum potassium 3.2 mEq/L
Rationale: Furosemide is a loop diuretic that causes potassium
wasting. Hypokalemia (normal 3.5–5.0) increases risk of
,Page 3 of 197
digoxin toxicity and cardiac dysrhythmias. Weight gain of 1
lb is minimal; 30 mL/hr urine output is adequate; BP is normal.
2. A client with unstable angina is started on IV heparin.
The aPTT level 6 hours later is 110 seconds. What should
the nurse do first?
A. Continue infusion as ordered
B. Stop the heparin infusion
C. Give protamine sulfate
D. Increase infusion rate
Correct Answer: B. Stop the heparin infusion
Rationale: Therapeutic aPTT for heparin is 1.5–2.5 times
control (approx 60–80 sec). 110 seconds indicates excessive
anticoagulation and bleeding risk. Stop infusion; notify
provider. Protamine is for severe bleeding, not first action.
3. A client post-MI develops crackles in both lung bases, S3
gallop, and BP 90/60 mmHg. Which condition does the
nurse suspect?
, Page 4 of 197
A. Cardiogenic shock
B. Pericarditis
C. Pulmonary embolism
D. Cardiac tamponade
Correct Answer: A. Cardiogenic shock
Rationale: S3 gallop + crackles indicate left ventricular
failure. Hypotension with these signs suggests cardiogenic
shock post-MI. Pericarditis causes chest pain relieved by
leaning forward. Tamponade shows muffled heart sounds,
distended neck veins, hypotension (Beck’s triad).
4. A client with hypertension is prescribed lisinopril. Which
finding indicates a therapeutic effect?
A. Heart rate 100 bpm
B. Urine output 20 mL/hr
C. Blood pressure 128/78 mmHg
D. Potassium 5.8 mEq/L
