Total-body irradiation is used as part of the destruction of the child's immune system necessary for a bone marrow transplant. The child is at great risk for complications because there is no supportive therapy until engraftment of the donor marrow takes place. Irradiation for palliative care is done selectively. The area that is causing pain or potential obstruction is irradiated. Lymphoma and leukemia are treated through a combination of modalities. Total-body irradiation is not indicated.
Answer to Question 2
ANS: B
When an allergic reaction is suspected, the drug is immediately discontinued. Any drug in the line should be withdrawn, and a normal saline infusion begun to keep the line open. The intravenous infusion is stopped to minimize the amount of drug that infuses. The infusion rate can be confirmed at a later time. Observation of the child for 10 minutes is essential, but it is done after the infusion is stopped. These signs are indicative of an allergic reaction, not an expected response.
