ANTIMICROBIAL RECALL ACTUAL EXAM
SCRIPT 2026 FULL QUESTIONS AND
CORRECT ANSWERS GRADED A+
●● broad spectrum penicillins. Answer: - ampicillin and amoxicillin
- good oral absorption (amoxicillin = excellent)
- broad spectrum (improved against gram negative organisms - e.coli,
salmonella, shingella, H. Influenza, H pylori, proteus)
●● How do penicillins and cephalosporins work?. Answer: By
weakening the cell wall and promoting lysis and death
●● Bactericidal drugs are. Answer: Directly lethal to bacteria at
achievable concentrations
●● Why are narrow spectrum drugs preferred over broad spectrum
antibiotics?. Answer: Broad spectrum antibiotics do the most to facilitate
emergence of resistance
●● How does bacterial resistance develop with penicillins?. Answer: -
production of penicillin binding proteins that have low affinity for
penicillins
-inability of penicillins to reach their target
, -inactivation of penicillins by bacterial enzymes
