Feedback:
During the arterial blood gas test, the nurse should implement measures to prevent complications after the arterial puncture. The nurse would not be involved in measuring the partial pressure of oxygen dissolved in plasma or the percentage of hemoglobin saturated with oxygen. In most cases, collection of the sample is not performed independently by the nurse.
