Answer to Question 1

ANS: A
Daptomycin is active against MRSA. Levofloxacin, TMP/SMZ, and ciprofloxacin are not active against MRSA.

Answer to Question 2

ANS: A, B, D
There are many reasons for the emergence of drug-resistant organisms in the treatment of TB. They include erratic patient adherence, drug doses that are too low, and drug regimens with too few drugs. The immunocompetence of the host does not affect drug resistance, nor does the fact that some agents are bacteriostatic.
