ABG interpretation Exam Questions with CORRECT Answers (Grade A+)
Question 1:
What are normal ABG values for PaCO₂?
Answer:
PaCO₂ 35-45 mmHg
Question 2:
What are normal ABG values for HCO₃⁻?
Answer:
HCO₃⁻ 22-26 mmol/L
Question 3:
What are normal ABG values for PaO₂?
Answer:
PaO₂ 80-100 mmHg
Question 4:
What are normal ABG values for SaO₂?
Answer:
SaO₂ > 94%
Question 5:
What are normal ABG values for pH?
Answer:
pH 7.35-7.45
Question 6:
What do the normal ABG values for pH, PaCO2, HCO3, PaO2, SaO2
reflect?
Answer:
These values reflect balanced respiratory and metabolic function.
Question 7:
What is the first step in interpreting an ABG?
Answer:
Assess pH to determine if the patient is acidotic (<7.35) or alkalotic (>7.45). This guides whether the
disorder is likely respiratory or metabolic.
Question 8:
What is respiratory acidosis?
Answer:
A primary increase in PaCO₂ (>45 mmHg) causing pH < 7.35. It occurs when ventilation is inadequate
