Which of the following actions is NOT appropriate for the nurse during the lumbar puncture procedure?

Filming the procedure for educational purposes is not appropriate during a lumbar puncture. This is primarily due to the need for maintaining the patient's privacy and confidentiality, especially in pediatric patients who may require special considerations. Recording such procedures may expose sensitive information and can lead to ethical and legal implications. Additionally, the focus during a lumbar puncture must be on the safety and comfort of the child, ensuring that they are adequately supported and attended to.

In contrast, the other actions are vital components of care during such a procedure. Using distraction techniques can help alleviate anxiety and fear in children, making the experience more manageable for them. Strict aseptic techniques are critical to prevent infection at the site of the lumbar puncture. Providing reassurance to the child can also significantly contribute to their comfort and compliance during the procedure. Each of these actions is founded on best practices in pediatric nursing care, aiming to foster a supportive and safe environment for the patient.
