Which action is recommended after a lumbar puncture?

• A. Lie Flat With No Pillow for at Least 4 Hours
• B. Stand and Move Around Slowly
• C. Take a Hot Bath to Relieve Pain
• D. Engage in Vigorous Exercise

Answer: (B)

After a lumbar puncture, the goal is to minimize leakage of cerebrospinal fluid at the puncture site to prevent a post-dural puncture headache. Lying flat with minimal pillow support for several hours helps keep CSF pressure stable and gives the puncture site time to seal. Standing, moving around, or increasing activity too soon can promote CSF leakage and trigger or worsen a headache. Hot baths or vigorous exercise aren’t helpful for this healing process and can aggravate the puncture site. If a severe headache develops, a clinician might consider further interventions, but the initial best practice is prolonged lying flat to protect the puncture site.
