NOTE: Please explain why the other answers are not correct.

3 pts. 12. You are shadowing an endocrinologist during her rounds in the hospital. You enter the room of a man who was admitted from the emergency department with a wide array of symptoms. Blood tests reveal hyperglycemia. The results of a glucose tolerance test are normal. Other blood tests show that he has normal levels of epinephrine and thyroid hormone, but levels of cortisol are abnormally high and ACTH is abnormally low. He (truthfully)says that he has not been taking any drugs or medications. Wanting to impress the doctor, you carefully consider these facts and suggest that (c) a. the patient has diabetes. b. the patient has Grave's disease c. the patient has a hypersecreting tumor of the adrenal cortex. d. the patient has a hypersecreting tumor of the adrenal medulla e. the patient is suffering side effects from long-term glucocorticoid therapy

Explanation / Answer

a)the patient doesnt have diabetes as excess of cortisol secretion has increased the level of sugar in the blood. blood sugar level has increased not because of decreased secretion of insulin

b)patient doesnt have graves disease as the level of ACTH is low. in graves disease, thyroid hormone secretion increases ACTH level

d)since the level of epinephrine is normal , there is no hypersecretion of adrenal medulla

e) patient mentions that he has not been under any medication, then glucocoticoid therapy can be ruled out in this situation

hence (c) is the correct option

hope the answer is clear to you
