Exhibits A nurse in an emergency department is assessing a client who has major depressive disorder. Which of the following actions should the nurse take first? (Click on the exhibit tabs for additional information about the client. There are three tabs that contain separate categories of data.)

Rationale: A. Administer ondansetron to the client for nausea: Treating nausea is important for comfort, but it does not address the most urgent risk. Nausea is not immediately life-threatening compared with potential complications from medication overdose. B. Obtain a blood glucose level: Checking blood glucose can provide useful information, but there is no indication of hypoglycemia or diabetes-related crisis in this scenario. It is not the priority action. C. Implement seizure precautions for the client: The client has been doubling the bupropion dose, which significantly increases the risk of seizures, especially at doses above the prescribed maximum. Seizure precautions address an immediate life-threatening risk and should be the first intervention. D. Obtain the client's weight: Monitoring weight is important for assessing nutritional status and the severity of depression, but it is not an immediate safety concern. Life-threatening risks, such as seizures, take priority.
