Place the steps for analyzing arterial blood gases in the proper order
1 . Assess HCO3– level for metabolic abnormalities.
2 . Assess PaO2 for hypoxemia.
3 . Examine PaCO2 for acidosis or alkalosis.
4 . Re-examine pH to determine level of compensation.
5 . Examine pH for acidemia or alkalemia.
a. 5, 1, 2, 4, 3 c. 1, 2, 4, 3, 5
