A client with leukemia is scheduled to undergo a stem cell transplant. The client asks, "Where do the stem cells come from?" What is the nurse's best response?
"Stem cells are extracted from the client's cancerous tissues."
"Stem cells are collected from the bone marrow of a matched donor."
"Stem cells are taken from a tumor and processed for transplantation."
"Stem cells are harvested from the client's peripheral blood."
The Correct Answer is B
A) This choice is incorrect because stem cells used in transplantation are typically not extracted from the client's cancerous tissues.
B) This choice is correct. In a stem cell transplant, stem cells are collected from the bone marrow of a matched donor (allogeneic transplant) or the client themselves (autologous transplant). These stem cells are then infused into the client's bloodstream to replace the damaged bone marrow and produce healthy blood cells.
C) This choice is incorrect because stem cells used in transplantation are not taken from a tumor.
D) This choice is incorrect because stem cells used in transplantation are not harvested from the client's peripheral blood.

Correct Answer is C
Explanation
A) This choice is incorrect because leukemia does not primarily affect the lymph nodes. It is a cancer of the blood and bone marrow, where abnormal white blood cells are produced.
B) This choice is incorrect because leukemia is not characterized by the overproduction of platelets. Platelets are involved in blood clotting, and their overproduction is not a feature of leukemia.
C) This choice is correct. Leukemia is a type of cancer characterized by the uncontrolled proliferation of abnormal white blood cells in the bone marrow. These abnormal cells then enter the bloodstream, crowding out healthy blood cells and impairing normal blood cell function.
D) This choice is incorrect because leukemia is not an autoimmune disorder. It is a cancerous condition involving abnormal white blood cell growth.
Correct Answer is B
Explanation
A) This choice is incorrect because assessing bone density and strength is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
B) This choice is correct. A CT scan is commonly used to identify enlarged lymph nodes and organs, which can occur in leukemia as a result of cancerous cell proliferation and infiltration into the lymphatic system and other organs.
C) This choice is incorrect because measuring lung capacity is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
D) This choice is incorrect because monitoring cardiac function is not the primary goal of a CT scan in the diagnostic evaluation of leukemia.
