Case 2: Cyanosis in a Patient with AIDS

You answered:

B Stop zidovudine and adminster high-dose folic acid.

This answer is incorrect. The patient could have zidovudine-related anemia or lactic acidosis, but the clinical history and arterial blood gas suggest a different diagnosis.

Choose another answer:

A Start intravenous pentamidine for presumptive treatment of Pneumocystis pneumonia.
C Stop dapsone and administer intravenous methylene blue.
D Administer high-dose corticosteroids for Kaposi’s sarcoma immune reconstitution inflammatory syndrome.
