A nurse is explaining the purpose of a computed tomography (CT) scan to a client with suspected leukemia. What is the primary goal of a CT scan in the diagnostic evaluation of leukemia?
Assess bone density and strength
Identify enlarged lymph nodes and organs
Measure the client's lung capacity
Monitor the client's cardiac function

Questions
Correct Answer is A
Explanation
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.
