Chapter 62: Assessment of the Endocrine System

1. What is the relationship between a hormone and its receptor?

A. When hormones bind to their specific receptors sites, they are protected from degradation.
B. Hormones will only produce effects on tissues that contain receptor sites for that hormone.
C. Receptor sites carry hormones in the blood to their proper target tissue.
D. A specific type of receptor site will secrete only one type of hormone.

2. What is the trigger for decreased hormone secretion for hormones regulated by negative feedback mechanisms? Increased:

A. enzymatic conversion of prohormone to active hormone.
B. circulating levels of secretory granules.
C. circulating levels of hormone.
D. target body tissue activity.

3. Which statement regarding hypothalamic function is true? The:

A. hypothalamus directly controls the secretion of all endocrine hormones.
B. hypothalamus uses neural and hormonal influences to regulate pituitary hormone secretion.
C. major role of the hypothalamus is to degrade circulating hormones when hormone secretion is no longer needed.
D. hypothalamus forms a barrier to prevent the nervous system from overriding the activity of the endocrine system.

4. What type of difficulty would you expect to find in the client who has had an infarct of the posterior pituitary gland?

A. Acid-base imbalance
B. Temperature regulation
C. Fluid and electrolyte imbalance
D. Maintenance of normal blood glucose levels

5. Which clinical manifestation(s) alerts you to a possible problem with adrenal function?

A. Peeling skin on the soles of the feet
B. Sudden-onset hypertension
C. Unplanned weight loss
D. Chronic bad breath

6. The client has a very low intake of dietary calcium. Which hormone will respond to this low calcium level?

A. Aldosterone
B. Thyrocalcitonin
C. Corticosteroids
D. Parathyroid hormone

7. Which statement about pancreatic endocrine function is true?

A. Pancreatic hormones are important but not essential for life.
B. Insulin and glucagon have opposite effects on carbohydrate metabolism.
C. Pancreatic hormones have the most complex of all feedback controlling mechanisms.
D. Insulin and glucagon have no roles in either protein metabolism or fat metabolism.

8. The risk for which endocrine-related problem increases with aging?

A. Dehydration
B. Muscle cramping
C. Chronic hypoglycemia
D. Excessive diaphoresis in warm environments

9. What is the purpose of suppression testing for endocrine function? To:

A. prevent neural input into endocrine function.
B. assess the effectiveness of counterregulatory hormone production and release.
C. determine the presence of hyperfunctioning of a specific endocrine gland or tissue.
D. suppress the normal feedback control systems so that each endocrine gland can be evaluated individually.
