Answer to Question 1

ANS: D
The bell factor for a 13.5-L water-sealed spirometer is 41.73 mL/mm. Therefore, 41.73 mL/1 mm = X mL/28 mm; X = 1168 mL, or 1.168 L.

Answer to Question 2

ANS: B
The bell factor for a 9-L water-sealed spirometer is 20.93 mL/mm. Therefore, 20.93 mL/1 mm = X mL/25 mm; X = 523 mL, or 0.523 L.
