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 D
Explanation
A) This choice is incorrect because gentle stretching exercises are generally safe and do not significantly increase the risk of bleeding in clients with low platelet counts.
B) This choice is incorrect because deep vein thrombosis (DVT) prophylaxis, such as leg exercises and anti-embolism stockings, is essential to prevent blood clots but is not directly related to bleeding risk.
C) This choice is incorrect because using a soft-bristled toothbrush helps prevent gum bleeding and trauma to the oral mucosa but does not address the risk of bleeding from other areas.
D) This choice is correct. Vigorous nose blowing can lead to trauma to the nasal mucosa and increase the risk of bleeding, especially in clients with low platelet counts who are prone to bleeding episodes.
Correct Answer is B
Explanation
A) This choice is incorrect because chemotherapy for acute lymphocytic leukemia (ALL) usually lasts much longer than a few weeks. ALL treatment consists of several phases, and the overall duration can extend over several years.
B) This choice is correct. Treatment for acute lymphocytic leukemia (ALL) typically involves multiple phases, including induction, consolidation, and maintenance therapy. The induction phase aims to achieve remission, the consolidation phase aims to eliminate any remaining cancer cells, and the maintenance phase aims to prevent relapse and keep the leukemia in remission. Overall, the treatment can extend over several years, depending on the client's response to therapy and risk factors.
C) This choice is incorrect because it does not accurately reflect the standard treatment approach for ALL. Clients with ALL do not typically switch from chemotherapy to radiation therapy after a few days.
D) This choice is incorrect because ALL treatment typically involves multiple rounds of chemotherapy, not just a single round. The goal is to achieve long-term remission and prevent relapse, which requires a more comprehensive treatment approach over an extended period.
