A client with suspected leukemia is scheduled for a lumbar puncture. What is the primary purpose of this procedure in the diagnostic evaluation of leukemia?
Assess cerebrospinal fluid for leukemic cells
Evaluate liver and kidney function
Measure blood glucose levels
Determine the client's platelet count
The Correct Answer is A
A) This choice is correct. A lumbar puncture is performed to assess cerebrospinal fluid (CSF) for the presence of leukemic cells in cases where leukemia may have spread to the central nervous system. This procedure helps determine if the client requires specific treatment to target leukemia in the CNS.
B) This choice is incorrect because a lumbar puncture is not primarily used to evaluate liver and kidney function.
C) This choice is incorrect because measuring blood glucose levels is not the primary purpose of a lumbar puncture.
D) This choice is incorrect because determining the client's platelet count is not the primary purpose of a lumbar puncture. Platelet counts are typically obtained through a blood test.

Correct Answer is B
Explanation
A) This choice is incorrect because exposure to benzene is indeed a known risk factor for developing leukemia. Benzene is a chemical compound found in certain industrial settings and can increase the risk of developing leukemia, particularly acute myeloid leukemia (AML).
B) This choice is correct. Exposure to benzene is associated with an increased risk of leukemia. Benzene is a known carcinogen and can cause damage to blood-forming cells in the bone marrow, leading to the development of leukemia in some individuals.
C) This choice is incorrect because while benzene exposure is associated with an increased risk of leukemia, it is not primarily linked to skin cancer.
D) This choice is incorrect because benzene exposure can affect individuals of all ages, not just children. It is a risk factor for leukemia development in adults as well as children.
Questions
Correct Answer is B
Explanation
A) This choice is incorrect because mild fatigue and weakness are common symptoms in leukemia and may be expected in the client's condition.
B) This choice is correct. Bruising and petechiae are signs of decreased platelet count and potential clotting abnormalities, which can lead to bleeding complications. Immediate intervention is necessary to prevent serious bleeding.
C) This choice is incorrect because a weight loss of 2 pounds in a month is not alarming and can be caused by various factors unrelated to leukemia.
D) This choice is incorrect because occasional headaches and dizziness are not immediate concerns in leukemia and may have other causes.
