Chapter 49 : Introduction to the Endocrine System Questions
Question 1 of 5
The nurse is reviewing the plan of care for a client with a disorder of the thyroid gland. Which diagnostic test will the nurse expect the physician to order to evaluate thyroid hormones?
Correct Answer: B
Rationale: A radioimmunoassay evaluates thyroid hormone function, specifically T3 and T4 levels. A CT or magnetic resonance imaging scan is used to detect a suspected tumor and to determine organ size and placement. Cortisol levels are used to assess adrenal function, not thyroid function.
Question 2 of 5
An instructor is preparing a teaching plan for a class on the various pituitary hormones. Which hormone is released by the posterior pituitary gland?
Correct Answer: C
Rationale: The posterior pituitary gland releases oxytocin and antidiuretic hormone. Somatotropin, prolactin, and adrenocorticotropic hormone are secreted by the anterior pituitary gland.
Question 3 of 5
A group of students is reviewing material about endocrine system function. The students demonstrate understanding of the information when they identify which of the following as secreted by the adrenal medulla?
Correct Answer: D
Rationale: The adrenal medulla secretes epinephrine and norepinephrine. Glucocorticoids and mineralocorticoids are produced by the adrenal cortex, while glucagon is secreted by the pancreas.
Question 4 of 5
A group of students is reviewing for a test on hormones. The students demonstrate understanding of the material when they state which of the following as being secreted by the kidneys?
Correct Answer: C
Rationale: The kidneys release renin and erythropoietin. Atrial natriuretic peptide is secreted by the atria of the heart, estrogen by the ovaries and placenta during pregnancy, and gastrin by the stomach to increase hydrochloric acid production.
Question 5 of 5
An instructor has just finished teaching a class about the endocrine system. The instructor determines that the students need additional instruction when they identify which of the following as an endocrine gland?
Correct Answer: D
Rationale: Although the kidneys secrete renin and erythropoietin, they are not typically considered endocrine glands. The pancreas, adrenal glands, and testes are recognized as endocrine glands due to their primary role in hormone secretion.
