Answer to Question 1

D
Prostaglandin analogs are first-line agents for treating POAG, and early treatment can stop the progression. Angle-closure glaucoma has a rapid onset of painful symptoms. POAG is more common in African Americans but angle-closure glaucoma is not. Surgery, not drugs, is the de-finitive treatment for angle-closure glaucoma.

Answer to Question 2

D
The object of Type IV hypersensitivity (delayed-type hypersensitivity) is to rid the body of bac-teria that replicate within macrophages. The macrophage activates the CD4 cell, which in turn activates the macrophage. The other cells listed are not a part of this response.
