Before performing a lumbar puncture, which preparation is recommended?

• A. Have the patient empty the bladder
• B. Have the patient fast for 12 hours
• C. Administer a laxative
• D. Shave the lumbar area

Answer: (A)

Focusing on pre-procedure comfort and maintaining a stable, clean field is the key concept here. Having the patient empty the bladder before a lumbar puncture helps minimize discomfort and the urge to void during the procedure, which keeps the patient still and reduces chances of movement that could complicate needle placement. It also helps maintain a clean, sterile area around the insertion site. Fasting isn't required for a lumbar puncture, a laxative isn't indicated, and shaving the lumbar area isn't routinely done—hair removal is not a standard step unless hair interferes with access.
