question from saunders book

ok so i was reviewing about the addisons and cushings from saunders book, took some notes about the signs and symptoms.

Cushings:

hypokalemia, hypocalcemia, etc etc...

After that, i did a 10-item quiz and encountered a question from the cd about s/s of cushings syndrome.

W/c of the ff lab findings would the nurse expect to note in this client with cushings syndrome:

a. glucose 110

b. potassium 5.5

c. wbc 6000

d. platelet 200,000.

So everything looked normal to me except for option B. But i was like "no, it cant be! in the book it says, patients with cushings syndrome has hypokalemia!" But as i went throught the rationale, it says that:

The client with Cushing's syndrome experiences HYPERKALEMIA, hyperglycemia, an elevated WBC count, and an elevated plasma cortisol and ACTH levels. These abnormalities are due the effects of excess glucocorticoids and mineralocorticoids in the body.

SO which one is right?? the saunders book that says clients with cushing has hypokalemia or the saunders cd that says they have hyperkalemia??
