EE Chapter 98 Antimicrobial Agents Q&A (1 OF 112) Sample Questions
1. Test shows a drug is resistant to Amoxicillin and Oxacillin but sensitive to Erythromycin, Vancomycin and some other penicillin. What kind of resistance is suspected?
- A. Methicillin-Resistant Staphylococcus Aureus (MRSA)
- B. Vancomycin-Resistant Enterococcus (VRE)
- C. Multidrug-Resistant Mycobacterium Tuberculosis (MDR-TB)
- D. Carbepenem-resistant Enterobacteriaceae (CRE) gut bacteria
1. Read the question. You are asked to identify a specific antibiotic resistance.
2. Look for cues and keywords. There are multiple cues here: resistant to Amoxicillin and Oxacillin, sensitive to Erythromycin, Vancomycin and some other penicillin. Key phrase, suspected resistance, using your cues you can eliminate options B and D. Between A and C, be guided by the fact that Mycobacterium tuberculosis is not sensitive to cell-wall synthesis inhibitors that include the groups of penicillins and cephalosporins.
3. Thus, the correct answer is A.
