Answer to Question 1

ANS: D
50 mm Hg is abnormal so the nurse will follow up. Normal capnography results are 35 to 45 mm Hg.

Answer to Question 2

ANS: B
Oxygen must be used cautiously in these types of patients. Hypoxemia helps to control ventilation in patients with chronic lung disease. Because low levels of arterial O2 provide the stimulus that allows a patient to breathe, administration of high oxygen levels may be fatal for patients with chronic lung disease. Patients with chronic lung disease have ongoing hypercarbia (elevated CO2 levels) and do not need to have CO2 administered or rebreathed with a paper bag.
