Answer to Question 1

ANS: C
Patients with healthy lungs achieve a steady state in only 5 min after changes, whereas those with chronic obstructive pulmonary disease (COPD) may require as long as 20 to 30 min. For example, if the patient's FiO2 is changed, the measured PaO2 will accurately reflect the patient's gas ex-change status within 5 min in healthy people but may require 20 to 30 min in patients with COPD.

Answer to Question 2

ANS: C
An elevated baseline (higher than 0 mm Hg) indicates rebreathing.
