Answer to Question 1

ANS: A
Cytomegalovirus pneumonia is an example of a latent infection that can reactivate during chronic immunosuppression, especially in solid organ and bone marrow transplant recipients.

Answer to Question 2

ANS: C
The spread of infection through the bloodstream from a remote site is called hematogenous dis-semination. This is an uncommon cause of pneumonia, which may occur in patients with right-sided bacterial endocarditis in whom fragments of an infected heart valve break off, embo-lize through the pulmonary arteries to the lungs, and produce either pneumonia or septic pulmo-nary infarcts.
