ABG (Arterial Blood Gas) Interpretation-
The Basics Exam Questions And Answers
The nurse is interpreting the following ABG results: pH 7.29, PaCO2
48, HCO3 25. Which of the following is occurring?
A.Metabolic acidosis
B.Respiratory alkalosis
C.Respiratory acidosis
D.Metabolic alkalosis -
correct answer ✅Answer: C
following is occurring?
Respiratory acidosis
Normal ranges are as follows: pH 7.35-7.45 PaCO2 35-45, HCO3 22-
26. This client's pH shows acidosis, the PaCO2 is high, and the HCO3
is normal. This client is in respiratory acidosis.

The Basics Exam Questions And Answers
Respiratory alkalosis
The pH shows acidosis, not alkalosis.
Metabolic acidosis
This client's PaCO2 is out of range, which means the source of the
imbalance is respiratory, not metabolic.
Metabolic alkalosis
The pH shows acidosis, not alkalosis. Additionally, the client's HCO3
is normal, so this imbalance does not have a metabolic source.
The nurse is interpreting the following ABG results: pH 7.44, PaCO2
50, HCO3 30. Which of the following is occurring?
A.Fully compensated respiratory alkalosis
B.Partially compensated metabolic alkalosis
C.Partially compensated respiratory alkalosis

D.Fully compensated metabolic alkalosis -
correct answer ✅Answer : D
Fully compensated metabolic alkalosis
Normal ranges are as follows: pH 7.35-7.45 PaCO2 35-45, HCO3 22-
26. This client's pH is normal, the PaCO2 reflects acidosis, and the
HCO3 reflects alkalosis. Since the PaCO2 and HCO3 is out of range,
there is an acid-base imbalance occurring, but since the pH is
normal, this client is fully compensated. The pH, while normal, is
closer to alkalosis than acidosis, so it can be concluded that the
client's body is compensating for alkalosis. Since the HCO3 matches
alkalosis, this client is in fully compensated metabolic alkalosis.
Partially compensated metabolic alkalosis
The client is fully compensated because the pH is back into the
normal range.
Fully compensated respiratory alkalosis
The client's source of this imbalance is not respiratory, because the
pH is closer to alkalosis and the respiratory source (PaCO2) reflects
acidosis. Since these do not match, the source is not respiratory but
metabolic.
