Final answer:
a) epoetin alfa.
To mitigate organ damage from chemotherapy, the doctor is likely to prescribe epoetin alfa, which is a synthetic form of erythropoietin to treat anemia and improve oxygen delivery to body tissues.
Step-by-step explanation:
To protect Teegan's heart and kidneys from damage caused by chemotherapy drugs, his doctor might prescribe a medication to manage the side effects of treatment. Given the provided options, the most likely drug to be prescribed in this context is epoetin alfa. Epoetin alfa is a synthetic form of erythropoietin (EPO), which is used medically to treat anemia resulting from chronic kidney disease or from chemotherapy. This medication stimulates the production of red blood cells (RBCs), which helps to increase oxygen delivery to tissues throughout the body and can ameliorate the anemia caused by chemotherapy.
Chemotherapy can lead to organ damage, including damage to the kidneys, which are responsible for the natural production of EPO. By administering synthetic EPO, the body can compensate for reduced kidney function and alleviate some of the strain on these organs. It's important to note that while epoetin alfa can be beneficial in treating chemotherapy-induced anemia, it is also associated with some risks such as increasing the viscosity of the blood which can lead to complications if not monitored properly.
