A nurse is caring for a patient who has acute kidney injury. The patient's ABG results are: pH: 7.26
PaCO2: 30 mm Hg HCO3: 14 mEq/L
Which of the following acid-base imbalances should the nurse identify the patient is experiencing?
Metabolic alkalosis
Respiratory acidosis
Metabolic acidosis
Respiratory alkalosis
The Correct Answer is C
Choice A reason: Metabolic alkalosis is characterized by a high pH and a high HCO3 level, which is not present in this scenario.
Choice B reason: Respiratory acidosis is characterized by a high PaCO2 and a low pH. Although the pH is low here, the PaCO2 is also low, ruling out respiratory acidosis.
Choice C reason: Metabolic acidosis is indicated by a low pH and a low HCO3 level, which aligns with the patient's ABG results.
Choice D reason: Respiratory alkalosis would present with a high pH and a low PaCO2, which is not the case here.
