Answer to Question 1

A, B, C, D, E

Feedback
Correct Exposure to radiation and a number of infections may result in profound congenital deformities. These include but are not limited to varicella, rubella, syphilis, parvovirus, cytomegalovirus, and toxoplasmosis. Certain maternal conditions such as diabetes and phenylketonuria may also affect organs and other parts of the embryo during this developmental period. Drugs such as antiseizure medication and some antibiotics, as well as chemicals, including lead, mercury, tobacco, and alcohol, also may result in structural and functional abnormalities.
Incorrect None

Answer to Question 2

C
The confirming diagnosis of AIDS usually occurs at a CD4 T-cell count of less than 200 cells/microliter. The normal CD4 T-cell count is 1,000 cells/microliter. The client's depleted CD4 T-cell count is not a manifestation of AZT efficacy.
