A nurse is preparing to administer a rectal suppository to a client. In which of the following positions should the nurse place the client for insertion of the suppository?

A. Supine: The supine position is not ideal for inserting a rectal suppository. In this position, it can be difficult for the nurse to adequately visualize the rectum and for the client to relax the anal sphincter, making insertion more challenging and potentially uncomfortable. B. Lying on the right side: Although the right side position is commonly used for other types of procedures, it is not the most recommended for rectal suppository insertion. The left side (Sim's position) is preferred for easier access. C. Prone position: The prone position (lying on the stomach) is not commonly used for inserting a rectal suppository, as it can be uncomfortable and not provide optimal access to the rectum. D. Sim's position: Sim's position (lying on the left side with the lower arm behind the body, and the upper leg bent toward the chest) is the most appropriate position for inserting a rectal suppository. This position allows easy access to the rectal area and is more comfortable for the client.
