Question 1 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 2 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 3 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.
Question 4 of 5
The nurse is caring for a client with diabetes who developed hypoglycemia. What can the nurse administer to the client to raise the blood sugar level?
Correct Answer: B
Rationale: Glucagon, secreted by pancreatic alpha cells, raises blood sugar levels by stimulating glycogenolysis in the liver. Insulin lowers blood sugar, while cortisone and estrogen do not directly affect blood glucose levels.
Question 5 of 5
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?
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.
