1. A patient is prescribed lisinopril for hypertension. Which mechanism of action correctly
describes this medication?
A. Blocks the binding of Angiotensin II to its receptors
B. Directly inhibits the release of renin from the kidneys
C. Inhibits the enzyme responsible for converting Angiotensin I to Angiotensin II
D. Antagonizes aldosterone receptors in the distal tubule
Answer: C
Conceptual Explanation: Lisinopril is an ACE inhibitor, which prevents the conversion of
Angiotensin I to Angiotensin II, a potent vasoconstrictor.
2. A client with a history of asthma is diagnosed with hypertension. Which beta-blocker
should the nurse clarify with the provider?
A. Metoprolol
B. Propranolol
C. Atenolol
,D. Esmolol
Answer: B
Conceptual Explanation: Propranolol is a non-selective beta-blocker that can cause
bronchoconstriction by blocking Beta-2 receptors, making it dangerous for patients with
asthma.
3. The nurse is assessing a patient taking Digoxin. Which symptom is the most specific early
indicator of digoxin toxicity?
A. Anorexia and nausea
B. Hyperkalemia
C. Yellow-green visual halos
D. Tachycardia
Answer: A
Conceptual Explanation: Gastrointestinal symptoms like anorexia, nausea, and vomiting
are often the earliest signs of digoxin toxicity, though visual changes are more specific to
late-stage toxicity.
4. A patient receiving a heparin infusion has an aPTT of 120 seconds (Control 30). What is the
priority nursing action?
A. Increase the infusion rate
B. Stop the infusion and prepare Protamine Sulfate
, C. Administer Vitamin K intramuscularly
D. Continue the infusion and recheck in 4 hours
Answer: B
Conceptual Explanation: An aPTT of 120 is significantly above the therapeutic range
(usually 1.5 to 2.5 times the control). Protamine Sulfate is the antidote for Heparin.
5. Which laboratory value must the nurse monitor closely for a patient taking Furosemide?
A. Serum Calcium
B. Serum Potassium
C. White Blood Cell count
D. Hemoglobin
Answer: B
Conceptual Explanation: Furosemide is a loop diuretic that causes significant excretion of
potassium, putting the patient at risk for hypokalemia.
6. A patient is scheduled for surgery and takes Warfarin daily. Which medication does the
nurse anticipate administering to reverse Warfarin’s effects?
A. Protamine Sulfate
B. Vitamin K
C. Glucagon
