Chapter 50 Questions
Question 1 of 5
The nurse is evaluating the laboratory results for a patient who has increased secretion of the anterior pituitary hormones. Which of the following findings should the nurse anticipate when reviewing the laboratory findings?
Correct Answer: C
Rationale: Increased secretion of adrenocorticotropic hormone (ACTH) by the anterior pituitary gland will lead to an increase in serum and urinary cortisol levels. An increase, rather than a decrease, in thyroxine level would be expected with increased secretion of thyroid-stimulating hormone (TSH) by the anterior pituitary. Aldosterone and catecholamine levels are not controlled by the anterior pituitary.
Question 2 of 5
The student nurse is caring for a patient with goitre and possible hyperthyroidism. Which of the following actions by the student nurse should cause the nursing instructor to intervene?
Correct Answer: A
Rationale: Palpation can cause the release of thyroid hormones in a patient with an enlarged thyroid and should be avoided. The other actions by the student nurse are appropriate when caring for a patient with an enlarged thyroid.
Question 3 of 5
The nurse is caring for a patient in the outpatient clinic who has a prescription for blood cortisol testing. Which of the following instructions should the nurse provide for the patient?
Correct Answer: C
Rationale: Cortisol levels are usually drawn in the morning when levels are highest. The other instructions would be given to patients who were having other endocrine testing.
Question 4 of 5
The nurse is interviewing a patient who has a possible thyroid disorder. Which of the following questions will provide the most useful information?
Correct Answer: D
Rationale: Because thyroid function affects metabolic rate, changes in weight may indicate hyper- or hypofunction of the thyroid gland. Nocturia, visual difficulty, and changes in stress level are associated with other endocrine disorders.
Question 5 of 5
The nurse is teaching a patient how to prepare for an oral glucose tolerance test (OGTT). Which of the following patient response indicates that the teaching has been effective?
Correct Answer: A
Rationale: Fasting for 12 hours before the procedure demonstrates that teaching has been effective. The patient is to be NPO 12 hours prior to the test. A clear fluid diet 12 hours pretest is not indicated. A full fluid diet 6 hours pretest is not indicated.
