The interviewer is asking this question to assess the candidate's ability to interpret arterial blood gas. Interpreting arterial blood gas can be difficult and confusing which can lead to incorrect diagnosis. There are many ways that a candidate can successfully answer this question, including speaking about the references they keep on hand to help them interpret results, or they can even speak to their clinical knowledge and expertise on the subject. A particularly strong answer to this question will include an example of when the candidate faced a difficult situation with an arterial blood gas result and was able to use their knowledge and expertise to interpret it.

"In my current anesthesiology assistant role, I consistently have to interpret arterial blood gas, and unfortunately, it is never an easy task. Because of how difficult it is to interpret arterial blood gas sometimes, and the severe consequences of misinterpretation, I keep a quick guide in my pocket so I can reference it if needed. While I do not have to reference the quick guide each time I read an arterial blood gas, I find that having the quick guide is helpful, because if I am in a tight situation, I am able to quickly pull it out and make a confident decision by looking at the chart and determining the abnormal values."
