Critical Care Registered Nurse (CCRN) Practice Exam

What must patients do during a lumbar puncture procedure?

1. Remain completely still

2. Walk around regularly

3. Stay awake for the entire procedure

4. Consume food prior to the procedure

The correct answer is: Remain completely still

During a lumbar puncture procedure, it is essential for patients to remain completely still. This requirement is crucial because any movement can disrupt the positioning of the needle, potentially leading to complications such as nerve injury or a failed procedure. The accuracy of the needle placement is vital for obtaining cerebrospinal fluid safely and effectively. Being still also helps to reduce anxiety and allows healthcare professionals to focus on the technical aspects of the procedure without distractions. While there may be situations where a patient can be relaxed or sedated, their ability to stay still remains paramount throughout the entirety of the procedure to ensure both safety and success. The other considerations—such as the need for walking around, staying awake, or consuming food before the procedure—do not directly support the primary objective of a lumbar puncture, which centers on obtaining a clear and safe sample of cerebrospinal fluid.
