A nurse is preparing to assess a client's thyroid gland. Which of the following actions should the nurse plan to take?

A. "Instruct the client to take small sips of water." Having the client take small sips of water helps the nurse observe the thyroid gland as it moves up and down with swallowing, making abnormalities more noticeable. B. "Ask the client to hyperextend their neck during palpation." The client should slightly extend (not hyperextend) their neck to relax the muscles and allow for better palpation of the thyroid gland. C. "Inspect the isthmus as the client holds their breath for 5 seconds." The thyroid gland is best observed during swallowing, not by holding the breath. D. "Assist the client to a supine position prior to the assessment." Thyroid assessment is performed with the client in a sitting or standing position, not lying down.
