While palpating the neck of a client diagnosed with a thyroid disorder, the nurse takes special care to be very gentle. What is the rationale for the nurse's action? Deep palpation of the thyroid can result in excessive release of thyroid hormone. The nurse must be careful not to risk occluding neck vessels and disrupting circulation. Care must be taken to avoid causing a choking sensation and subsequent hormone release as a response. The thyroid is likely swollen, and pain must not be compounded by touch that is rough.
