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. Check the blood pressure: Assessing blood pressure is not the immediate priority when a client is found unresponsive. Vital signs should be taken after confirming the client’s responsiveness, pulse, and breathing, and after activating emergency help if necessary. B. Obtain emergency help: The first and most critical action is to call for emergency assistance to initiate the facility’s emergency response system. Immediate help ensures that advanced life support measures and resuscitation equipment can be provided without delay. C. Bring a glucometer to the room: Checking blood glucose is important if hypoglycemia is suspected, but it should only be done after confirming airway, breathing, and circulation. Delaying emergency activation while obtaining equipment may waste resuscitation time. D. Feel for a carotid pulse: Assessing the carotid pulse is part of the initial assessment sequence but should occur simultaneously or immediately after emergency help is called. The PN should ensure help is on the way before beginning pulse or breathing checks.
