Question 1 of 5

Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

Correct Answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis.

Choices A, C, and D are incorrect.
Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis.
Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status.
Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
