Answer to Question 1

ANS: B, C
Daptomycin has been approved only for bloodstream and skin infections caused by S. aureus, including MRSA infections, and would not be indicated for a CAP infection. In patients with CAP, daptomycin poses a higher risk of serious cardiorespiratory side effects. Daptomycin does not cause renal impairment and is no more likely to produce bacterial resistance than other antibiotics. Daptomycin can be used to treat MRSA infections.

Answer to Question 2

ANS: A, D
Bacitracin and Polymyxin B are both topical antibiotics. Daptomycin, ofloxacin, and rifampin are not formulated to be administered topically.
