A nurse is caring for a client with leukemia who has developed severe anemia and thrombocytopenia. Which process in the pathophysiology of leukemia contributes to these complications?
Increased production of normal red blood cells
Accumulation of normal platelets in the blood
Suppression of normal bone marrow stem cells
Infiltration of healthy tissues by cancerous cells
The Correct Answer is C
A) This choice is incorrect because leukemia does not lead to the increased production of normal red blood cells. Instead, it causes the overproduction of abnormal white blood cells.
B) This choice is incorrect because leukemia does not lead to the accumulation of normal platelets in the blood. Thrombocytopenia, or low platelet count, is common in leukemia due to the suppression of normal platelet production in the bone marrow.
C) This choice is correct. In leukemia, the proliferation of abnormal white blood cells crowds out and suppresses the normal bone marrow stem cells responsible for producing red blood cells, platelets, and other white blood cells. This suppression leads to anemia and thrombocytopenia.
D) This choice is incorrect because while cancerous cells may infiltrate healthy tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not other organs or tissues.

Correct Answer is C
Explanation
A) This choice is incorrect because chemotherapy may cause a decreased platelet count, leading to a risk of bleeding, rather than increased blood clotting and thrombosis.
B) This choice is incorrect because chemotherapy does not typically cause elevated blood pressure and hypertension.
C) This choice is correct. Nausea, vomiting, and hair loss are common side effects of chemotherapy due to its effect on rapidly dividing cells, including hair follicles and cells lining the digestive tract.
D) This choice is incorrect because excessive bleeding and hemorrhage are not common side effects of chemotherapy in leukemia treatment.
Correct Answer is C
Explanation
A) This choice is correct. Using a soft-bristled toothbrush helps prevent gum bleeding and trauma to the oral mucosa, reducing the risk of infection in clients with low platelet counts.
B) This choice is incorrect because during leukemia treatment, outdoor activities may expose the client to potential sources of infection. It is better to avoid crowded places and maintain good hand hygiene.
C) This choice is correct. Raw fruits and vegetables may carry bacteria and pathogens, and the client with leukemia, particularly those undergoing chemotherapy, is at a higher risk of infection. It is advised to thoroughly wash and cook fruits and vegetables before consumption.
D) This choice is incorrect because although emotional support from friends and family is essential, it is crucial to limit the number of visitors to reduce the risk of exposure to potential infections.
