Respiratory Therapist Exam — Sample

An arterial blood gas shows pH 7.24, PaCO2 58 mm Hg, HCO3 24 mEq/L, and PaO2 68 mm Hg while the patient breathes room air. Which interpretation is most accurate?

A Uncompensated respiratory acidosis with hypoxemia

B Uncompensated metabolic acidosis with normal oxygenation

C Fully compensated respiratory acidosis with normal oxygenation

D Partially compensated metabolic alkalosis with hypoxemia

Explanation. The pH is below 7.35 and the PaCO2 is above 45 mm Hg, while the HCO3 is still inside the normal 22 to 26 mEq/L range. That is an acute, uncompensated respiratory acidosis. A PaO2 of 68 mm Hg on room air is below the usual 80 mm Hg threshold, so hypoxemia is present as well.
