Accurate Questions and Answers |
South University Graded A

Question 1

A patient with hypertension is prescribed lisinopril. What is the primary mechanism of action?
A. Blocks beta receptors
B. Inhibits angiotensin-converting enzyme
C. Inhibits calcium channels
D. Increases potassium excretion

Correct Answer: B
Rationale: Lisinopril, an ACE inhibitor, inhibits angiotensin-converting enzyme, reducing
angiotensin II production, which leads to vasodilation and decreased blood pressure.



Question 2

A patient with type 2 diabetes is prescribed metformin. What should the nurse monitor for as a
rare but serious side effect?
A. Hypoglycemia
B. Lactic acidosis
C. Hyperkalemia
D. Weight gain

Correct Answer: B
Rationale: Metformin can cause lactic acidosis, particularly in patients with renal impairment or
other risk factors. Hypoglycemia is rare with metformin, and it typically causes weight loss, not
gain.



Question 3

A patient with heart failure is prescribed furosemide. What electrolyte imbalance is most likely
to occur?
A. Hyperkalemia
B. Hypokalemia

, 2


C. Hypernatremia
D. Hypomagnesemia

Correct Answer: B
Rationale: Furosemide, a loop diuretic, increases potassium excretion, leading to hypokalemia,
which can cause arrhythmias or muscle weakness.



Question 4

A patient with atrial fibrillation is prescribed warfarin. What lab value should the nurse monitor?
A. aPTT
B. INR
C. Platelet count
D. Hemoglobin

Correct Answer: B
Rationale: Warfarin’s anticoagulant effect is monitored via INR to ensure therapeutic levels
(typically 2–3 for atrial fibrillation). aPTT is used for heparin.



Question 5

A patient with asthma is prescribed albuterol. What is the expected therapeutic effect?
A. Reduced inflammation
B. Bronchodilation
C. Decreased mucus production
D. Increased oxygen saturation

Correct Answer: B
Rationale: Albuterol, a beta-2 agonist, causes bronchodilation, relieving acute bronchospasm in
asthma. It does not directly reduce inflammation or mucus.



Question 6

A patient with depression is prescribed fluoxetine. How long does it typically take for
therapeutic effects to occur?
A. 1–2 days
B. 2–4 weeks
C. 6–8 weeks
D. 24 hours

, 3


Correct Answer: B
Rationale: Fluoxetine, an SSRI, requires 2–4 weeks to achieve therapeutic effects due to gradual
serotonin level changes in the brain.



Question 7

A patient with a bacterial infection is prescribed amoxicillin. What should the nurse teach the
patient to report immediately?
A. Mild diarrhea
B. Rash and difficulty breathing
C. Nausea
D. Fatigue

Correct Answer: B
Rationale: Rash and difficulty breathing suggest a severe allergic reaction (anaphylaxis) to
amoxicillin, requiring immediate medical attention.



Question 8

A patient with heart failure is prescribed spironolactone. What should the nurse teach the patient
to avoid?
A. Potassium-rich foods
B. High-fiber foods
C. Dairy products
D. Grapefruit juice

Correct Answer: A**: Spironolactone, a potassium-sparing diuretic, can cause hyperkalemia.
Avoiding potassium-rich foods (e.g., bananas, oranges) prevents complications.



Question 9

A patient with a seizure disorder is prescribed phenytoin. What adverse effect should the nurse
monitor?
A. Gingival hyperplasia
B. Weight gain
C. Hypokalemia
D. Hypertension

, 4


Correct Answer: A
Rationale: Phenytoin commonly causes gingival hyperplasia, requiring good oral hygiene. Other
effects are less typical.



Question 10

A patient with a peptic ulcer is prescribed omeprazole. What is the mechanism of action?
A. Neutralizes gastric acid
B. Inhibits proton pump
C. Enhances mucus production
D. Kills H. pylori

Correct Answer: B
Rationale: Omeprazole, a proton pump inhibitor, blocks the H+/K+ ATPase pump, reducing
gastric acid secretion.



Question 11

A patient with COPD is prescribed ipratropium. What is the primary therapeutic effect?
A. Reduces inflammation
B. Inhibits bronchoconstriction
C. Increases mucus production
D. Enhances oxygen diffusion

Correct Answer: B
Rationale: Ipratropium, an anticholinergic, inhibits bronchoconstriction by blocking
acetylcholine, improving airflow in COPD.



Question 12

A patient with a deep vein thrombosis is prescribed heparin. What lab value should the nurse
monitor?
A. INR
B. aPTT
C. Platelet count
D. Hemoglobin

Correct Answer: B
Rationale: Heparin’s anticoagulant effect is monitored via aPTT to ensure therapeutic levels.
INR is used for warfarin.
