The practical nurse (PN) and unlicensed assistive personnel (UAP) enter a client's room and find the client lying on the bed. The PN determines that the client is unresponsive. Which instruction should the PN give the UAP first?

A. Feeling for a carotid pulse is part of the assessment process but is not the first step in responding to an unresponsive client. Immediate action to summon emergency help is the priority. B. Bringing a glucometer to the room is not appropriate at this stage. While checking blood glucose might be necessary, the first step is to get emergency assistance. C. Obtaining emergency help is the most critical first step when encountering an unresponsive client. Emergency help ensures that appropriate interventions are initiated promptly. D. Checking the blood pressure is part of a complete assessment but is not the most urgent action. The priority is to call for emergency assistance rather than performing further assessments.
