The nurse is evaluating a client's neck for thyroid enlargement. Which action by the nurse is appropriate during the evaluation?
- A. Inspect changes in pigmentation in the neck.
- B. Perform repeated palpation of the thyroid gland.
- C. Palpate the thyroid gland gently.
- D. Examine the skin of the neck for excessive oiliness.
Correct Answer: C
Rationale: The nurse should inspect the neck for thyroid enlargement and gently palpate the thyroid gland. Repeated palpation can lead to a sudden release of thyroid hormones in cases of thyroid hyperactivity, which may have serious implications. Changes in pigmentation or oiliness of the neck are not relevant to thyroid assessment.

- A. Glucocorticoids
- B. Mineralocorticoids

A nursing student asks the instructor why the pituitary gland is called the 'master gland.' What is the best response by the instructor?
- A. It regulates the function of other endocrine glands.
- B. It is the gland that is responsible for regulating the hypothalamus.
- C. The gland does not have any other function other than to cause secretion of the growth hormones.
- D. It regulates metabolism.
Correct Answer: A
Rationale: The pituitary gland is called the master gland because it regulates the function of other endocrine glands through its hormone secretions. However, the hypothalamus influences the pituitary, and the pituitary secretes multiple hormones beyond growth hormone, not just regulating metabolism.
The nurse is attempting to locate the thyroid gland of a client in order to determine if it is enlarged. Where should the nurse palpate the thyroid gland?
- A. Mid trachea
- B. Distal to the carotid arteries
- C. The lower neck anterior to the trachea
- D. The upper neck posterior to the trachea
Correct Answer: C
Rationale: The thyroid gland is located in the lower neck anterior to the trachea, divided into two lateral lobes joined by the isthmus. Palpation in this area helps assess for enlargement.
What does the nurse understand will be released to maintain a relatively constant level of blood sugar in a client with normal function of the pancreas?
- A. Cortisol
- B. Glucagon
- C. Insulin
- D. Somatostatin
Correct Answer: D
Rationale: Somatostatin, secreted by pancreatic delta cells, inhibits the release of insulin and glucagon, helping maintain stable blood sugar levels. Cortisol, glucagon, and insulin have more direct roles in raising or lowering blood sugar.
