The correct answer is A
The disease is Pneumocystis pneumonia, which is caused by an agent now believed to be a fungus rather than true bacteria. Pneumocystis carinii pneumonia is seen in immunocompromised patients, particularly in those with AIDS, cancer, and in malnourished children. It can be the AIDS-defining illness.
Congestive heart failure (choice B) predisposes the patient to pulmonary edema.
Pulmonary embolus (choice C) can cause pulmonary infarction or sudden death.
Rheumatoid arthritis (choice D), particularly in miners, can cause formation of lung nodules similar to subcutaneous rheumatoid nodules.
Systemic lupus erythematosus (choice E) can cause pleuritis, but is not associated with a significantly increased incidence of pneumonia.
