Answer to Question 1

ANS: C
Classes of antiretroviral agents include nucleoside reverse transcriptase inhibitors (e.g., zidovudine, didanosine, stavudine, lamivudine, abacavir), nonnucleoside reverse transcriptase inhibitors (e.g., nevirapine, delavirdine, efavirenz), and protease inhibitors (e.g., indinavir, saquinavir, ritonavir, nelfinavir, amprenavir, lopinavir, ritonavir). Dapsone, pentamidine, and Bactrim are anti-infectives.

Answer to Question 2

ANS: D
The basic defect of hemophilia A is a deficiency of factor VIII. The partial thromboplastin time measures abnormalities in the intrinsic pathway (abnormalities in factors I, II, V, VIII, IX, X, XII, HMK, and KAL). The prothrombin time measures abnormalities of the extrinsic pathway (abnormalities in factors I, II, V, VII, and X). Fibrinogen level is not dependent on the intrinsic pathway. Platelets are not affected with hemophilia A.
