Question 28#

Excessive administration of normal saline for fluid resuscitation can lead to what metabolic derangement?

A. Metabolic alkalosis
B. Metabolic acidosis
C. Respiratory alkalosis
D. Respiratory acidosis

Correct Answer is B

Comment:

Sodium chloride is mildly hypertonic, containing 1 54 mEq of sodium that is balanced by 1 54 mEq of chloride. The high chloride concentration imposes a significant chloride load on the kidneys and may lead to a hyperchloremic metabolic acidosis. Sodium chloride is an ideal solution, however, for correcting volume deficits associated with hyponatremia, hypochloremia, and metabolic alkalosis.
