Answer to Question 1

ANS: D
Correction of metabolic alkalosis is aimed at restoring normal fluid volume and electrolyte con-centrations, especially K+ and Cl levels. Inadequate fluid volume, especially if coupled with hypochloremia, causes excessive secretion and loss of H+ and K+ ions because of the great need to reabsorb Na+ ions. Thus, in treating this type of alkalosis, it is important to supply adequate fluids containing Cl ions. If hypokalemia is a primary factor, then KCl is the preferred corrective agent. In cases of severe metabolic alkalosis, acidifying agents, such as dilute hydrochloric acid or ammonium chloride may be infused directly into a large central vein.

Answer to Question 2

ANS: A
A normal BE is 2 mEq/L. A positive BE (>+2 mEq/L) indicates a gain of base or loss of acid from nonrespiratory causes. A negative BE (<2 mEq/L) indicates a loss of base or a gain of acid from nonrespiratory causes.
