Question 2

Common complications of chemotherapy include:

A)bleeding.
B)infection.

Answer 2

D
Because chemotherapy reduces the rate of cell division of rapidly dividing cells,the ability of the bone marrow to replace cells is reduced,affecting leukocyte,erythrocyte,and platelet counts.

Question 3

Answer 3

A
Bone marrow should be HLA matched,but ABO matching is not critical.
