module test

1. a lumbar puncture may be performed to obtain which of the following for lab analysis?

brain tissue
neuroglial tissue
cerebrospinal fluid
bone marrow

Explanation:

Lumbar puncture, also known as a spinal tap, is a medical procedure where a needle is inserted into the spinal canal, usually in the lower back. The main purpose is to obtain cerebrospinal fluid (CSF). CSF surrounds the brain and spinal cord and can provide important diagnostic information when analyzed in a lab. Brain tissue is not obtained via lumbar puncture as that would require a biopsy. Neuroglial tissue (supportive cells in the nervous system) is not the target of a lumbar puncture. Bone marrow is obtained via a bone marrow biopsy (usually from the hip or sternum), not a lumbar puncture.

Answer:

Cerebrospinal fluid
