b. Sodium 150 mEq/L and potassium 3.6 mEq/L
c. Sodium 135 mEq/L and potassium 6.9 mEq/L
d. Sodium 148 mEq/L and potassium 5.5 mEq/L

Question 2

Answer to Question 1

ANS: C
Severe hyperkalemia, with a potassium level of 6.9 mEq/L, requires aggressive treatment with Kayexalate and sorbitol to increase the body's excretion of potassium. The normal range for serum potassium is 3.5 to 5.5 mEq/L, so patients with the other potassium levels would not be treated aggressively or would need potassium supplementation.

Answer to Question 2

ANS: D
Hypomagnesemia, like hypokalemia, enhances the action of digitalis and causes digitalis toxicity. Laxatives and diuretics can deplete both of these electrolytes.
