Question 1 of 5
The nurse is reviewing a client's laboratory studies and determines that the client has an elevated calcium level. What does the nurse know will occur as a result of the rise in the serum calcium level?
Correct Answer: D
Rationale: A rise in serum calcium stimulates the thyroid gland to release calcitonin, which inhibits calcium release from bones to lower blood calcium levels and maintain homeostasis.
Question 2 of 5
A client has a dysfunction in one of his glands that is causing a decrease in the level of calcium in the blood. The nurse knows which gland should be evaluated for dysfunction?
Correct Answer: B
Rationale: The parathyroid glands secrete parathormone, which increases blood calcium levels when serum calcium decreases. The thyroid, thymus, and adrenal glands do not primarily regulate calcium levels.
Question 3 of 5
The nurse is caring for a client with an immunodeficiency disorder. Lab results show that the client does not have an adequate number of T lymphocytes needed to improve immune function. Which gland should be investigated for dysfunction?
Correct Answer: A
Rationale: The thymus gland secretes thymosin and thymopoietin, which are essential for T lymphocyte development, critical for immune function. The parathyroid, thyroid, and adrenal glands do not directly influence T lymphocyte production.
Question 4 of 5
The nurse is caring for a client who is having difficulty with falling asleep and staying asleep. The nurse suggests the client try over-the-counter melatonin to help with this issue. The nurse explains that what gland is responsible for the decreased secretion of melatonin?
Correct Answer: A
Rationale: The pineal gland secretes melatonin, which regulates sleep cycles and mood. Decreased melatonin secretion can contribute to sleep difficulties. The adrenal, thyroid, and thymus glands do not secrete melatonin.
Question 5 of 5
The nurse is caring for a client having chronic pain from arthritis. What type of hormone is released in response to the stress of this pain that suppresses inflammation and helps the body withstand stress?
Correct Answer: C
Rationale: Glucocorticoids, such as cortisol, are released by the adrenal cortex to suppress inflammation and help the body cope with stress, such as chronic pain from arthritis. Testosterone, mineralocorticoids, and estrogen have different functions.
