Answer to Question 1
B
The effects of chemotherapy on bone marrow cause immunosuppression because bone marrow produces many immune factors. Chemotherapy does not generally increase allergic reactions. Certain types of chemotherapy may cause nausea and vomiting or loss of lean body mass, but these side effects are not caused by the drugs' effects on bone marrow.
Answer to Question 2
B
Bone marrow cells and cells lining the gastrointestinal tract have a rapid turnover rate, which makes them highly susceptible to damage caused by chemotherapy. The drugs do not target these cells specifically, nor are they exposed to higher doses of the drugs. The impact of chemotherapy drugs on these cells is not related to absorption and excretion.
