Critical care air methods test
questions with correct answers
100% PASS
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
