Chapter 49 Questions
Question 1 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 2 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.
Question 3 of 5
A client is scheduled to have a test to determine thyroid function. What should the nurse ask the client prior to scheduling the testing?
Correct Answer: A
Rationale: The nurse should ask about recent diagnostic tests using iodine, as these can interfere with thyroid function tests. Payment ability, fluid intake, and birth control pills are not relevant to thyroid testing accuracy.
Question 4 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 5 of 5
A client is scheduled for a diagnostic test to measure blood hormone levels. The nurse expects that this test will determine which of the following?
Correct Answer: C
Rationale: Measuring blood hormone levels helps determine the functioning of endocrine glands. A radioimmunoassay determines the concentration of substances in plasma, while radiographs assess organ size and location. Blood sugar levels are measured separately, typically for diabetes management.
