3.5.1 Anion Gap Flashcards
Cation Gap is used as a form of quality control for electrolyte measurements
T or F
F
Anion
May be used to distinguish between normochloremic and hyperchloremic
metabolic acidosis
Anion Gap
Normochloremic = Low anion gap
Hyperchloremic = High anion gap

Formulas for Anion Gap:
AG = (Na + K)-(HCO3 + Cl)
AG = Na - (HCO3 + Cl)
