Critical care air methods test
questions well answered
Five rules of ABG interpretation - correct answer ✔✔1. Evaluate the pH is it normal?
Two. Evaluate the PCO2. Is it acute or chronic for respiratory disorder?
Three. Evaluate the HCO3 and calculate the anion gap for metabolic disorder or delta gap. Check
if metabolic acidosis is present.
Four. Identify the primary disorder.
Five determine if compensation is present in the degree of compensation using winter's
formula. Is there more than one disorder?
Anion gap formula, and normal values - correct answer ✔✔AG = NA -(Cl + HCO3). Normal range
12 +/- 4. Abnormal >16
ABG normal ranges - correct answer ✔✔pH: 7.35 - 7.45
PaCO2: 35 -45
HCO3 (bicarb): 22 - 26
pO2. : 80-100
Anion gap metabolic acidosis causes - correct answer ✔✔MUDPILERS
Methanol
Uremia
DKA
Propylene glycol
Iron, Isoniazide
