Answer to Question 1

ANS: A
Serum potassium (K+) levels would be less than 3.5 mEq/L. Hypokalemia is especially likely to occur when a patient exhibits vomiting, diarrhea, or heavy diuresis. Between 3.5 and 4.5 mEq/L is the low end of normal range for serum potassium. Between 4.6 and 5 mEq/L is the high end of normal range for serum potassium. Serum K+ levels higher than 5.5 mEq/L indicate hyperkalemia, which occurs most commonly when a patient is given excessive amounts of potassium supplementation.

Answer to Question 2

ANS: C
Acetazolamide is used to reduce intraocular pressure associated with glaucoma. Mannitol is an osmotic diuretic used to decrease intracranial pressure. Diuretics such as furosemide or ethacrynic acid are used to reduce fluid volume in extravascular spaces. Diuretics are not used to treat periorbital edema.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
