Correct Answer is A

Explanation

A. Cushing syndrome is characterized by central obesity (excess adipose tissue in the trunk), slender extremities, a moon-shaped face, and other features like a buffalo hump. This is due to prolonged exposure to elevated cortisol levels.
B. High levels of potassium and low levels of sodium are not associated with Cushing syndrome, which typically presents with hypokalemia and hypernatremia.
C. Wasting of the abdomen is not a feature of Cushing syndrome. The skin may become fragile, but it is not typically calloused.
D. Edema is not a primary feature; rather, fat redistribution to the trunk and face is more common.

A. "Drink 8 ounces of fluid every hour while awake." B. "Consume 15 grams of carbohydrates every 1 to 2 hours." C. "Monitor blood glucose levels every 4 hours." D. "Take the usual dosage of insulin."

Correct Answer is C

A. Drinking fluids is important to prevent dehydration, but it is not the priority over monitoring blood glucose levels.
B. Consuming carbohydrates is necessary to prevent hypoglycemia, but this is not the primary concern during illness.
C. Monitoring blood glucose levels every 4 hours is the priority action because blood glucose can fluctuate significantly during illness, increasing the risk of hyperglycemia or diabetic ketoacidosis.
