A nurse is caring for an older adult client who has acute delirium. Which of the following actions should the nurse take first?

Choice A Reason: Determining the client's level of consciousness is correct. Delirium is characterized by a sudden change in mental status, including altered consciousness, confusion, and impaired attention. Assessing the client's level of consciousness helps the nurse understand the severity of the condition and whether the client is experiencing any immediate risks. Choice B Reason: Administer an anxiolytic medication is incorrect. Medication administration should not be the first action because the nurse needs to assess the client's condition first to determine if medication is appropriate. Additionally, the underlying cause of the delirium should be identified and treated if possible. Choice C Reason: Keep lights on in the client's room is incorrect. While maintaining proper lighting can be important for safety, it is not the first action because it doesn't address the underlying cause or assess the client's level of consciousness. Choice D Reason: Encouraging visits from family members is incorrect. Involving family members can provide emotional support, but it's not the first action because the client's condition should be assessed and stabilized before involving others in care.
