Let's say you are caring for a patient in our PACU whose respiratory function has taken a turn for the worse. Tell me how you would proceed.

"In a situation like this, I understand that it is important to gather as much information about the patient and the patient's current situation before proceeding with any additional respiratory treatment. I always consider oxygen levels following a major procedure. I would have the nurses continue to monitor all vitals and the number of breaths per minute. The next steps depend on how the patient responds. Simply supplementing oxygen often helps the lungs improve following a long surgery. However, there are some situations in which a ventilator may be needed."

To effectively answer this question, explain that you would collect all pertinent information on the patient, including respiratory rate O2 saturation for hypoxemia and other respiratory signs, and then make a medical determination. Depending on the situation and your assessment, this can and should include an ABG analysis, supplemental oxygen, or ventilatory support if needed.
