Answer to Question 1

Ans:
C, D, E

Feedback:

Children differ as to their clinical presentation of HIV infection when compared to adults. Failure to thrive (gain weight/height), CNS abnormalities (listlessness), and developmental delays are the most prominent primary manifestation of HIV infection in children. Answers A and B are normal growth and developmental tasks of a 6-month-old.

Answer to Question 2

Ans:
A

Feedback:

Although this phenomenon is not well understood, increasing proportions of lymphocytes become unresponsive with age, and CD4+ T lymphocytes are the most severely affected. B lymphocytes recognize more antigens, not fewer, and expression of cytokines and their cellular receptors decreases.
