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

Choice A rationale Allowing a patient to walk independently after receiving antianxiety preoperative medications, such as benzodiazepines, is a major safety risk. These medications frequently cause drowsiness, ataxia, and orthostatic hypotension, which significantly increase the risk of falls and related injuries. The nurse must prioritize physical safety by ensuring the patient remains in bed or is assisted by staff if movement is absolutely necessary. Independent ambulation is strictly contraindicated once these central nervous system depressants are administered. Choice B rationale Informed consent must be obtained before the administration of any mind-altering or sedative medications. Antianxiety drugs impair the client's cognitive function, judgment, and ability to process complex information, rendering them legally unable to provide truly informed consent. If the nurse allows the client to sign after medication administration, the consent is considered invalid and unethical. All legal documentation regarding the procedure must be finalized while the client is fully alert, oriented, and mentally competent. Choice C rationale Education regarding the surgical procedure should ideally occur during the preoperative phase before any sedative medications are given. Antianxiety medications interfere with memory consolidation and the ability to focus, meaning the client is unlikely to retain or understand the information provided. Effective patient teaching requires an alert mind. Attempting to educate the client at this stage is ineffective and could lead to post-operative confusion or non-compliance because the patient cannot recall the instructions or risks explained. Choice D rationale Placing side rails in an upright position is a standard safety intervention after a patient receives preoperative sedation or antianxiety medication. These drugs cause altered levels of consciousness and decreased coordination, which makes the patient vulnerable to accidentally falling out of bed. Ensuring the side rails are up provides a physical barrier and serves as a reminder for the patient to stay in bed. This action is a direct nursing responsibility aimed at maintaining a safe environment.
