An 8-year-old child with the diagnosis of meningitis is to have a lumbar puncture. What should the nurse explain is the purpose of this procedure?

  • A. To measure the pressure of cerebrospinal fluid
  • B. To obtain a sample of cerebrospinal fluid for analysis
  • C. To relieve intracranial pressure
  • D. To assess the presence of infection in the spinal fluid
Correct Answer: B

Rationale: The primary purpose of a lumbar puncture is to obtain a sample of cerebrospinal fluid for analysis. This sample helps in diagnosing conditions such as meningitis by evaluating the presence of pathogens or abnormalities in the cerebrospinal fluid. Measuring the pressure of cerebrospinal fluid (Choice A) is not the main objective of a lumbar puncture, although it can be done during the procedure. Relieving intracranial pressure (Choice C) is not the direct purpose of a lumbar puncture, as other interventions are typically used for this purpose. Assessing the presence of infection in the spinal fluid (Choice D) is related to the overall goal of obtaining a sample for analysis, making it a secondary outcome of the procedure.
