Final answer:
The nurse refrains from shouting from a distance, which is least helpful when communicating with a client with a hearing impairment.
Step-by-step explanation:
The nurse refrains from shouting from a distance, which is least helpful when communicating with a client with a hearing impairment. Shouting from a distance can distort sound and make it difficult for the client to understand. Instead, the nurse should speak loudly and clearly, facing the client directly. The nurse can also use gestures and facial expressions to enhance communication.
