NCLEX-PN® ExaminationReduction of Risk PotentialEasy
A client is scheduled for a lumbar puncture. The LPN should ensure the client is placed in which position for the procedure?
- ASupine with legs extended.
- BProne with head turned to the side.
- CSide-lying with knees drawn to the chest and chin tucked.
- DHigh Fowler's with arms supported.
Show answer & explanationAnswer & explanation
Correct answer: C. Side-lying with knees drawn to the chest and chin tucked.
The side-lying fetal position (knees drawn to the chest, chin tucked) or a sitting position leaning over a table helps to maximize the space between the vertebrae, facilitating easier and safer insertion of the spinal needle during a lumbar puncture.
Why the other options are wrong
- A. Supine with legs extended does not open the intervertebral spaces effectively for a lumbar puncture.
- B. The prone position is incorrect and would make access to the lumbar spine difficult.
- D. High Fowler's position is for breathing or feeding, not for a lumbar puncture.
Lumbar Puncture Positioning
The specific body position required for a client undergoing a lumbar puncture to optimize access to the subarachnoid space and ensure client safety.
- Goal: maximize space between lumbar vertebrae
- Common positions: side-lying fetal position or sitting position leaning forward
- Proper positioning is crucial for successful and safe needle insertion
