After a lumbar puncture, which measure helps reduce headache?

• A. Encourage fluids
• B. Restrict fluids
• C. No position changes
• D. Immediate ambulation

Answer: (A)

Post-lumbar puncture headaches come from CSF leaking at the puncture site, which lowers CSF pressure and causes pain that is often worse when upright. Encouraging fluids helps by increasing CSF production and volume, which can raise pressure at the leak site and lessen the headache. Restricting fluids or moving around too soon would not address the leak and can worsen symptoms, and immediately ambulating would likely increase CSF loss. So, keeping the patient well-hydrated is the most helpful measure to reduce the headache after a lumbar puncture.
