NURS 5334 ANTIMICROBIAL RECALL QUIZ
PART 1: QUESTIONS 1–25 (WITH ANSWERS + RATIONALES)
1. Which antibiotic class inhibits bacterial cell wall
synthesis?
A. Tetracyclines
B. Penicillins
C. Aminoglycosides
D. Macrolides
Answer: B. Penicillins
Rationale: Penicillins (beta-lactams) inhibit bacterial cell
wall synthesis by binding to penicillin-binding proteins,
leading to cell lysis. Other classes target protein synthesis.
,2. Vancomycin is primarily effective against:
A. Gram-negative bacteria
B. Gram-positive bacteria
C. Fungi
D. Viruses
Answer: B. Gram-positive bacteria
Rationale: Vancomycin blocks cell wall synthesis in Gram-
positive organisms, including MRSA.
3. Which lab value should be monitored during
aminoglycoside therapy?
A. Liver enzymes
B. Creatinine and BUN
C. Hemoglobin
D. Troponin
Answer: B. Creatinine and BUN
,Rationale: Aminoglycosides are nephrotoxic, so kidney
function must be monitored.
4. What is the most serious adverse effect of vancomycin?
A. Ototoxicity
B. Hyperglycemia
C. Hypertension
D. Constipation
Answer: A. Ototoxicity
Rationale: Vancomycin can damage the auditory nerve
leading to hearing loss.
5. Tetracyclines should NOT be given to:
A. Adults over 60
B. Children under 8 and pregnant women
C. Patients with hypertension
D. Patients with diabetes
, Answer: B. Children under 8 and pregnant women
Rationale: Tetracyclines cause permanent tooth
discoloration and bone growth inhibition.
6. What is the mechanism of action of macrolides?
A. Inhibit DNA replication
B. Inhibit 50S ribosomal subunit
C. Destroy cell wall
D. Increase folic acid synthesis
Answer: B. Inhibit 50S ribosomal subunit
Rationale: Macrolides block protein synthesis in bacteria.
7. Which antibiotic is commonly used to treat MRSA?
A. Amoxicillin
B. Vancomycin
C. Ciprofloxacin
D. Metronidazole
