Question 1 of 5
A nurse is caring for a client who has acute kidney injury (AKI). Which of the following arterial blood gas values would the nurse expect this client to have?
Correct Answer: A
Rationale: The correct answer is A: pH 7.26, HCO₃ 14, PaCO₂ 30. In acute kidney injury (AKI), the kidneys cannot regulate acid-base balance, leading to metabolic acidosis. The pH is low (acidosis), HCO₃ is low indicating metabolic acidosis, and PaCO₂ is low due to compensatory respiratory alkalosis.
Choices B and D have high pH values, which are not consistent with metabolic acidosis.
Choice C has a normal HCO₃ value, which is not expected in AKI.
Choice C also has a high PaCO₂, which is not consistent with compensatory respiratory alkalosis in metabolic acidosis.
