Question

Quizplus · Accepted Answer

A lumbar puncture is primarily performed to measure the pressure of cerebrospinal fluid and to collect a sample of it for analysis, which can help in determining intracranial pressure among other diagnostic purposes. It does not directly measure electric potentials of the brain, muscle response to stimulation, or the status of the respiratory system.
