Question

(1).

Your patient's laboratory results indicate hyponatremia, hyperkalemia, and low serum corticosteroid levels even after ACTH has been administered. Your patient is most likely diagnosed with:

Select one:

a. Cushing Syndrome

b. Addison Disease

c. Graves Disease

d. SIADH

(2).Exophthalmos is a condition associated with

Answer 1

Correct answer is

B. Addison Disease.

Because : In case of addison disease adrenal glands secrete less amount of cortisol and aldosterone.A deficiency of aldosterone in particular causes the body to excrete large amounts of sodium and retain potassium, leading to low levels of sodium and high levels of potassium in the blood.

Excess excretion of Sodium causes hyponatremia

Less excretion of Potassium causes hyperkalemia.

Why other options are not correct :

A. Cushing syndrome: In case of cushing syndrome level of corticosteroid hormones get increased. So low serum corticosteroid is not possible.

C. Grave's disease: It is associated with over production of thyroid hormone. It has no relationship with corticosteroid.

D. SIADH: in case of SIADH hyponatremia is seen. But Potassium level remains normal.It is associated with abnormal ADH hormone secretion.
