A 28-year-old woman is found to have a CD4+ T-lymphocyte count of 150 cells/µL. She is HIV-positive and not currently on antiretroviral therapy. Which opportunistic infection prophylaxis should be initiated?
✓ Correct Answer: Option C
Prophylaxis for Pneumocystis jirovecii pneumonia (PCP) with trimethoprim-sulfamethoxazole is indicated when the CD4 count falls below 200 cells/µL. MAC prophylaxis (azithromycin) is for CD4 < 50 cells/µL.
