Question 5 of 5
Which abnormal value requires immediate intervention to improve oxygenation?
Correct Answer: D
Rationale: All the values are abnormal, but the low PaO2 indicates that the patient is at the point on the oxyhemoglobin dissociation curve where a small change in the PaO2 will cause a large drop in the O2 saturation and a decrease in tissue oxygenation. The nurse should intervene immediately to improve the patient's oxygenation.
