Final answer:
Option 1: "If I cannot detect the client's pulse, I will have another AP verify this with me."
Step-by-step explanation:
A do-not-resuscitate (DNR) order is a legal document that states that medical personnel should not take steps to revive or resuscitate a patient if their heart stops or they stop breathing. The correct statement by the assistive personnel (AP) that indicates an understanding of caring for a client with a DNR order is Option 1: "If I cannot detect the client's pulse, I will have another AP verify this with me." This statement shows that the AP understands the importance of confirming the absence of a pulse before initiating any resuscitation efforts.
