Answer to Question 1

ANS: D
The most successful BMTs come from suitable HLA-matched donors. The timing of a BMT depends on the disease process involved. It usually follows intensive high-dose chemotherapy or radiotherapy. Usually, parents only share approximately 50 of the genetic material with their children. A one in four chance exists that two siblings will have two identical haplotypes and will be identically matched at the HLA loci. The decision to continue chemotherapy or radiotherapy if BMT fails is not appropriate to discuss with the parents when planning the BMT. That decision will be made later.

Answer to Question 2

ANS: B
Bone marrow from a donor is infused intravenously, and the transfused stem cells migrate to the recipient's marrow and repopulate it.
