The nurse is reviewing a patient's arterial blood gas results and realizes that the oxygen saturation level reflects which of the following?
1. ratio of oxygenated hemoglobin to total hemoglobin
2. evidence of autoregulation
3. percentage of cardiac output
4. content of oxygen in arterial blood
1
Rationale: The measurement of SaO2 or oxygen saturation by arterial blood gas analysis is a measurement of the ratio of oxygenated hemoglobin to total hemoglobin. The oxygen saturation level within the arterial blood gas analysis is not evidence of autoregulation or the percentage of cardiac output. The content of oxygen in arterial blood is expressed as CaO2.
