A nurse is caring for a client who reports constipation. The provider has prescribed an enema. Identify the sequence of steps the nurse should take to administer the enema.

Choice A rationale Verification of the client's identity is the critical first step in the nursing process to prevent medical errors. Using at least two identifiers, such as the name and date of birth on the wristband, ensures the right procedure is performed on the right patient. This aligns with national patient safety goals and must occur before any equipment is prepared or interventions are initiated. Failure to verify identity can lead to significant legal and clinical complications in care. Choice B rationale Providing privacy is a fundamental aspect of nursing ethics and patient dignity, especially during invasive procedures involving the perineal area. Closing the curtains or door minimizes the client's psychological stress and embarrassment, which can otherwise lead to muscle tension. Relaxation of the external anal sphincter is necessary for the comfortable insertion of the tubing. Maintaining a professional environment by securing privacy fosters a therapeutic relationship and encourages the client to cooperate with the procedure. Choice C rationale The Sims' position involves the client lying on their left side with the right knee flexed toward the chest. This position is scientifically preferred because it uses the natural anatomy of the colon to facilitate fluid flow. In this position, the sigmoid colon is situated lower than the rectum, allowing gravity to help the enema solution move deeper into the bowel. This enhances the effectiveness of the treatment in softening stool and stimulating peristalsis for easier evacuation. Choice D rationale Proper insertion of the enema tip is the final step in the preparation sequence before fluid administration. The nurse should lubricate the tip and insert it approximately 7 to 10 centimeters toward the umbilicus in an adult. This direction follows the natural curve of the rectal canal, preventing mucosal injury or perforation. Accurate placement ensures the fluid enters the rectal vault directly, which triggers the stretch receptors necessary to initiate the defecation reflex and relieve constipation.
