A patient's PaO2 level is 76 mm Hg. This finding is not causing the nurse concern because
1. the patient is 83 years old.
2. the patient is intubated.
3. the patient has diabetes.
4. the patient is recovering from anesthesia.
1
Rationale: Age affects normal ABG values. Elderly people have a lower PaO2 level with a decrease in approximately 10 mm Hg per decade. Normal ABG values are ranges for normal, healthy adults. It is important to establish a baseline for the individual because abnormal values become "normal" for some individuals. There is not enough information about the patient to determine if intubation would impact this patient's PaO2 level. Diabetes would not impact this patient's PaO2 level. There is not enough information about the patient to determine if anesthesia is impacting this patient's PaO2 level.
