Question 2

Answer to Question 1

Ans:
D

Feedback:

There is a subset of slow progressors: the long-term nonprogressors, who account for 1 of all HIV infections. These people have been infected for at least 8 years, are antiretroviral naive, have high CD4+ cell counts, and usually have very low viral loads. They are being investigated to determine how they maintain viral suppression of HIV.

Answer to Question 2

Ans:
C

Feedback:

Chronic granulomatous disease, because it affects phagocytic function, increases susceptibility to soft tissue infections, particularly of the skin, lungs, lymph nodes, and liver. Selective IgA deficiency and deficient IgG2 subclass antibodies can predispose people to infection, but those infections respond readily to antibiotic treatment. Ataxia-telangiectasia can cause skin and liver problems, but its primary manifestations are ataxia and telangiectasia.
