Exam Questions
1. A patient is prescribed 500 mg of amoxicillin every 8 hours. How many
grams will the patient receive in 24 hours?
A. 1 g
B. 1.5 g
C. 2 g
D. 2.5 g
Rationale: 500 mg every 8 hours means 3 doses in 24 hours (24 ÷ 8 = 3). Total dose:
500 mg × 3 = 1500 mg = 1.5 g.
2. What is the primary action of furosemide?
A. Increase blood pressure
B. Promote diuresis
, C. Enhance clotting
D. Reduce pain
Rationale: Furosemide, a loop diuretic, inhibits sodium and chloride reabsorption in
the loop of Henle, promoting fluid excretion.
3. A patient receiving IV heparin should be monitored for which lab value?
A. INR
B. aPTT
C. Hemoglobin
D. Creatinine
Rationale: Activated partial thromboplastin time (aPTT) monitors heparin’s
anticoagulant effect, ensuring therapeutic dosing.
4. Which medication is used to treat acute bronchospasm in asthma?
A. Montelukast
B. Albuterol
C. Theophylline
D. Fluticasone
Rationale: Albuterol, a short-acting beta-2 agonist, rapidly relieves bronchospasm by
relaxing airway smooth muscles.
5. What is a common side effect of lisinopril?
A. Hypokalemia
B. Dry cough
C. Tachycardia
D. Hypoglycemia
Rationale: Lisinopril, an ACE inhibitor, causes bradykinin accumulation, leading to a
dry cough.
6. A patient is prescribed morphine. What is a priority nursing assessment?
A. Blood pressure
B. Respiratory rate
C. Temperature
D. Pulse oximetry
Rationale: Morphine, an opioid, can cause respiratory depression, making respiratory
rate monitoring critical.
7. Which antibiotic class is associated with ototoxicity and nephrotoxicity?
A. Penicillins
B. Aminoglycosides
C. Macrolides
D. Cephalosporins
Rationale: Aminoglycosides (e.g., gentamicin) can damage the kidneys and inner ear.
