Answer to Question 1

ANS: A
The right side of the Pulmonetic Systems LTV 1000 contains the following: (1) a small opening for the alarm sound that should never be covered, (2) a 22-mm connector for the main inspiratory flow line, (3) an external connection for the exhalation valve, and (4) two flow-transducer con-nectors that attach to the patient Y-adapter.

Answer to Question 2

ANS: C
Locate the minute volume of 10 L/min on the right side of the chart. Follow the 10 L/min line down until it intersects with the 0.70 vertical line. Follow the vertical line left to read the input oxygen flow (L/min).
