Before a lumbar puncture, the client should be advised to do what?

Before a lumbar puncture, advising the client to void prior to the procedure is essential for several reasons. A lumbar puncture involves inserting a needle into the lower back to access the spinal canal, which can be uncomfortable and may put pressure on the bladder. If a client has a full bladder, this can increase discomfort during the procedure and may pose a risk of bladder injury.

Additionally, having an empty bladder can help enhance the clinician’s access to the spinal canal, as a full bladder can create tension in the surrounding abdominal and pelvic areas, complicating positioning and technique. Ensuring that the client has voided before the procedure not only helps to make the experience more comfortable but also minimizes potential complications.

The other options do not align with the best practice recommendations for this procedure. For instance, drinking a large amount of water could lead to discomfort, and eating a heavy meal is generally not advisable as it could distract or potentially complicate the procedure if there’s any need for sedation. Resting for several hours is typically unnecessary right before the procedure unless otherwise indicated by specific health conditions. Therefore, encouraging the client to void is the most relevant and beneficial guidance before a lumbar puncture.
