The nurse is setting up the equipment to assist with a sigmoidoscopy while the practical nurse (PN) positions the client in a flat prone position. Which action should the nurse implement?

A. Demonstrate to the PN how to position the client more effectively for the procedure: The nurse is responsible for ensuring correct positioning to optimize visualization and safety during a sigmoidoscopy. Providing guidance or demonstration supports safe practice and enhances the PN’s competence. B. Arrange for unlicensed assistive personnel to assist the PN during the procedure: While additional assistance may be helpful, it does not address whether the client is positioned correctly, which is the immediate priority for procedural safety and effectiveness. C. Assume care of the client and assign the PN to the care of a different client: Reassigning responsibilities may delay the procedure and does not utilize the opportunity for the PN to learn proper technique. Collaboration and teaching are preferred. D. Acknowledge that the PN has positioned the client safely and correctly: Simply acknowledging the position without verifying or guiding may result in suboptimal visualization or risk to the client. The nurse must ensure accuracy rather than assume correctness.
