Difficulty: MediumBasic Care and Comfort

Following a diagnostic lumbar puncture, a client is monitored in the outpatient observation area. The practical nurse is responsible for the client's immediate recovery care. Which positioning strategy should the nurse implement?

  1. Keep the client flat in a supine position.Answer
  2. B
    Place the client in a high-Fowler's position.
  3. C
    Maintain the client in a side-lying position with knees drawn to the chest.
  4. D
    Position the client prone with a pillow under the chest.

Answer

Keep the client flat in a supine position.
After a lumbar puncture, the client must remain flat (usually supine) for a period prescribed by the provider (often 4 to 8 hours). This specific positioning strategy minimizes tension and hydrostatic pressure on the dural puncture, preventing cerebrospinal fluid (CSF) from leaking out. CSF leakage leads to decreased intracranial volume, resulting in a severe, throbbing spinal headache.

Step-by-Step Solution

1
Identify the nature of the procedure.
A lumbar puncture involves inserting a needle into the subarachnoid space to withdraw cerebrospinal fluid (CSF).
Understanding the anatomical disruption helps predict potential post-procedure complications.
2
Determine the most common complication.
The most frequent complication is a spinal headache caused by the continued leakage of CSF from the dural puncture site.
Nursing interventions must prioritize the prevention of this specific adverse event.
3
Select the appropriate intervention to mitigate the risk.
Positioning the client flat (supine) minimizes gravity-induced hydrostatic pressure on the puncture site, allowing the dura to seal and preventing CSF loss.
Proper mechanical positioning is a direct and effective basic care measure within the practical nurse's scope.
