A nurse has administered preoperative medications to a client. Which of the following actions should the nurse implement?

A. Educate the client about the surgical procedure.: Patient education regarding the surgical procedure and risks must be completed before any sedative or anesthetic agents are administered. Medication administration can impair cognitive function and the ability to process complex information. Teaching provided after preoperative medication is ineffective and does not meet the standards for informed participation. B. Provide assistance to the bathroom.: Preoperative medications often include sedatives or opioids that cause orthostatic hypotension and impaired coordination. Allowing a medicated client to ambulate, even with assistance, increases the risk of falls and injury. The client should be encouraged to void before medication administration and remain in bed afterward. C. Have the client sign the informed consent.: Informed consent must be obtained while the client is fully conscious and cognitively intact, prior to the administration of mind-altering medications. A signature obtained after preoperative sedation is legally invalid and ethically compromised. The nurse must verify that the consent is signed and on the chart before giving the medication. D. Place side rails in an upright position.: Safety is the priority after the administration of preoperative medications that induce drowsiness or dizziness. Raising the side rails provides a physical barrier to prevent the client from attempting to get out of bed unassisted. This action is a standard nursing intervention to prevent falls in the immediate preoperative period.
