ABG Interpretation Exam Questions with CORRECT Answers (Grade A+)
Question 1:
ABG Analysis: Questions to Ask Yourself
Is the pH normal?
Answer:
The best answer is the response that directly addresses the question stem.
Question 2:
Is the CO2 normal?
Is the HCO3 normal?
Match the CO2 or the HCO3 with the pH
Answer:
The best answer is the response that directly addresses the question stem.
Question 3:
Does the CO2 or the HCO3 go the opposite direction of the pH?
Are the pO2 and the O2 saturation normal?
Step One
Answer:
The best answer is the response that directly addresses the question stem.
Question 4:
The first step in analyzing ABGs is to look at the pH. Normal blood pH is 7.4, plus or minus 0.05, forming
the range 7.35 to 7.45. If blood pH falls below 7.35
it
Answer:
The best answer is the response that directly addresses the question stem.
Question 5:
is acidic. If blood pH rises above 7.45, it is alkalotic.
If
Answer:
is acidic. If blood pH rises above 7.45, it is alkalotic. If
Question 6:
it falls into the normal range, label what side of 7.4 it
falls on. Lower than 7.4 is normal/acidic, higher than
Answer:
The best answer is the response that directly addresses the question stem.
, Question 7:
7.4 is normal/alkalotic.
Answer:
7.4 is normal/alkalotic.
Question 8:
Step One pH
Answer:
look at the pH
Normal blood pH is 7.4, plus or minus 0.05
the range 7.35 to 7.45
blood pH falls below 7.35 it is acidic
blood pH rises above 7.45, it is alkalotic
pH is in the normal range,
label what side of 7.4 it falls on
Lower than 7.4 is normal/acidic
higher than 7.4 is normal/alkalotic
Question 9:
Step Two pCO2
Answer:
examine the pCO2
Normal pCO2 levels are 35-45mmHg
Below 35 is alkalotic
above 45 is acidic.
Question 10:
Step Three HCO3
Answer:
HCO3 level
Normal HCO3 level is 22-26 mEq/L
below 22, the patient is acidotic
above 26, the patient is alkalotic
Question 11:
Step Four
Answer:
Next match either the pCO2 or the HCO3 with the pH to determine the acid-base disorder. For
example, if the pH is acidotic, and the CO2 is acidotic, then the
acid-base disturbance is being caused by the respiratory system. Therefore, we call it a
respiratory
acidosis. However, if the pH is alkalotic and the HCO3
is alkalotic, the acid-base disturbance is being caused
by the metabolic (or renal) system. Therefore, it will be a metabolic alkalosis.
