Case 2: Cyanosis in a Patient with AIDS

You answered:

A Start intravenous pentamidine for presumptive treatment of Pneumocystis pneumonia.

This answer is incorrect. Although this patient is at risk for Pneumocystis pneumonia given his low CD4 count, the clinical history and arterial blood gas findings are not consistent with this diagnosis. In addition, the patient is taking dapsone, which would further diminish the likelihood that he has Pneumocystis pneumonia.

Choose another answer:

B Stop zidovudine and adminster high-dose folic acid.
C Stop dapsone and administer intravenous methylene blue.
D Administer high-dose corticosteroids for Kaposi’s sarcoma immune reconstitution inflammatory syndrome.
