Final answer:
The action by the UAP that requires the nurse to intervene is placing the client on the back with the client's head to the side. Hence the correct answer is option B
Step-by-step explanation:
The action by the UAP that requires the nurse to intervene is Option B. Placing the client on the back with the client's head to the side is a contraindicated position for a client with right-sided paralysis. This position can increase the risk of aspiration and compromise respiratory function. The nurse should intervene and ensure that the client is positioned properly to maintain their safety and well-being.
