Quizplus · Accepted Answer

Exposure to a large air bubble would cause a decrease in the partial pressure of oxygen (PO2) in the arterial blood sample, resulting in a decreased PCO2 as well. This is because the air bubble would replace some of the oxygen and carbon dioxide in the blood. However, the exposure would not affect the pH of the sample. Therefore, only options I and III are incorrect, and the correct answer is B.
