1. For a patient prescribed hydrochlorothiazide (HydroDIURIL), the nurse should closely monitor which laboratory test value? A. Sodium B. Glucose C. Calcium D. Chloride Correct answer: B. Glucose Thiazide and thiazide-like diuretics are associated with adverse metabolic effects of hyperglycemia; therefore, close monitoring of blood glucose levels are needed. Other metabolic disturbances include hyperlipidemia and hyperuricemia. 2. The nurse is providing education to a patient prescribed spironolactone (Aldactone) and furosemide (Lasix). What information does the nurse explain to the patient? A. Using two drugs increases blood osmolality and the glomerular filtration rate. B. This combination promotes diuresis but decreases the risk of low levels of potassium. C. The lowest dose of two different types of diuretics are more effective than a large dose of one type. D. This combination maintains water balance to protect against dehydration and electrolyte imbalance. Correct Answer: B Spironolactone is a potassium-sparing diuretic; furosemide is a potassiumlosing diuretic. Giving these together minimizes potassium loss. 3. Which laboratory test result is a common adverse effect of furosemide (Lasix)? A. Hypokalemia B. Hypernatremia C. Hyperchloremia D. Hypophosphatemia Correct answer: A Furosemide is a potent loop diuretic, and the most common adverse effect of loop diuretics is electrolyte imbalances. This results in major electrolyte losses of potassium and sodium and, to a lesser extent, calcium. 4. The nurse would question the use of mannitol (Osmitrol) for which patient condition? A. Increased intraocular pressure
