Chapter 49 : Introduction to the Endocrine System Questions
Question 1 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 2 of 5
The nurse is evaluating a client's neck for thyroid enlargement. Which action by the nurse is appropriate during the evaluation?
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.
Question 3 of 5
During physical examination of a client with a suspected endocrine disorder, the nurse assesses the body structures. The nurse gathers this data based on the understanding that it is an important aid in which process?
Correct Answer: A
Rationale: The evaluation of body structures helps detect evidence of hormone hypersecretion or hyposecretion, aiding in the assessment of specific endocrine gland dysfunctions. Radiographs are used to detect tumors or determine organ size and location, while testosterone levels are assessed through blood tests.
Question 4 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.
Question 5 of 5
A client is experiencing an increase in blood glucose levels. The nurse understands that which of the following hormones would be important in lowering the client's blood glucose level?
Correct Answer: A
Rationale: Insulin, released by the beta islet cells of the pancreas, lowers blood glucose levels when they rise above normal. Parathormone regulates calcium levels, melatonin influences sleep cycles and mood, and calcitonin inhibits calcium release from bones.
