Following a lumbar puncture, which position is typically recommended to prevent headaches?

• A. Supine
• B. Prone
• C. Sitting
• D. Standing

Answer: (A)

Lying flat on the back after a lumbar puncture helps prevent post-procedure headaches by minimizing CSF leakage through the puncture site and maintaining stable CSF pressure. When you stay horizontal, gravity doesn’t promote further leakage and the brain is less likely to sag, which reduces the single most common cause of post-LP headaches. Typically, this means staying supine for several hours and then gradually resuming activity as tolerated, with good hydration and monitoring for any headache or other symptoms. Sitting, standing, or other upright positions would increase the likelihood of CSF leakage and headache in the immediate recovery period.
