To get this one correct, there is a very important detail in the question that you needed to notice, and it is: The patient is breathing room air!
Now, when you look at their results, you should know that a PaO2 above 120 torr is not possible for a patient that is only breathing room air. This would require that the patient is receiving some type of supplemental oxygen. So you know that there is an error with the sample.
In the case, you wouldn’t want to report these erroneous results and there is no indication for a bronchodilator at this time. So now you know that the correct answer has to be C.
The correct answer is: C. Discard the sample and obtain a new one
