Step-by-step explanation:
If the nurse is having difficulty palpating the thyroid while examining the patient's neck, the next appropriate action would be to document this finding as abnormal. Difficulty in palpating the thyroid may indicate an issue with the size or location of the thyroid gland. However, further investigation is required to determine the cause of this finding, and it is not within the nurse's scope of practice to diagnose a slow growing goiter or signs of hypothyroidism without consulting a physician.
