What is the first instruction a practical nurse (PN) should give to a UAP when they find a client unresponsive?

In this situation, the most appropriate first instruction for a practical nurse (PN) to give to a UAP when encountering an unresponsive client is to feel for a carotid pulse. This action is critical because it helps determine whether the client has any signs of life, specifically circulation.

Assessing the carotid pulse allows the UAP to quickly establish if the client has a heartbeat, which is essential for deciding the next steps in care. If the pulse is found, further interventions can follow, whereas finding no pulse would necessitate immediate activation of emergency protocols and initiation of CPR.

Starting CPR immediately, checking blood pressure, or calling for emergency assistance are all important, but they are contingent upon the assessment of the client's condition. Therefore, the immediate priority of checking for a carotid pulse ensures that the response is directed appropriately based on the client's status.
