A nurse in the emergency department is implementing a plan of care for an older adult client who is experiencing delirium tremens. Which of the following actions should the nurse take first?

A. Starting IV fluids is important to correct fluid and electrolyte imbalances, but not the first priority. B. The priority action for a client experiencing delirium tremens (DTs)—a severe form of alcohol withdrawal—is to administer benzodiazepines, such as diazepam, to prevent seizures, reduce agitation, and stabilize vital signs. C. Raising the side rails is a safety measure, but controlling the symptoms of DTs with medication takes priority to reduce risk of injury, seizures, and death. D. While obtaining a medical history is necessary for complete care, it is not the immediate priority in this emergency situation.
