The nurse is caring for a client who overdosed on lorazepam. What is the priority nursing assessment?

A. Current weight: Weight is useful for medication dosing and nutritional assessment, but it does not guide immediate management of benzodiazepine overdose. Lorazepam toxicity primarily affects neurologic and respiratory function. Weight assessment can be deferred until the client is stabilized. B. Capillary refill: Capillary refill reflects peripheral perfusion and circulatory status. Lorazepam overdose typically does not cause primary vascular compromise. This finding is less urgent than assessing neurologic and respiratory depression. C. Level of consciousness: Lorazepam is a benzodiazepine that causes central nervous system depression. Altered level of consciousness increases the risk for airway obstruction and respiratory failure. Immediate assessment guides airway protection and need for supportive interventions. D. Pain level: Pain assessment is important for overall care but is not a priority in sedative overdose. CNS depression may blunt pain perception. Stabilization of neurologic status takes precedence.
