الإجابة: D. Pneumocystis jiroveci pneumonia
An IV drug user with sexual risk and major weight loss most likely has advanced HIV. Fever, exertional dyspnea, marked hypoxia and bilateral interstitial infiltrates are the classic picture of Pneumocystis jirovecii pneumonia, which the sources link to HIV with CD4 <200. CMV, varicella and Candida pneumonias are much less likely here.
