Answer to Question 1

ANS: B
The predicted normal FVC for a 20-year-old, 180-cm man approaches 5.60 L.

Answer to Question 2

ANS: B
The FEV1 is a measurement of the volume exhaled in the first second of the FVC (Figure 20-2, A). To ensure validity of the FEV1, the measurement must originate from a set of three acceptable FVC trials. The first second of forced exhalation begins at the zero time point (Figure 20-3). To ensure reliability of the FEV1, the largest FEV1 and second largest FEV1 from the acceptable tri-als should not vary by more than 0.150 L. Consistent with its definition, the largest FEV1 (body temperature, ambient pressure, saturated BTPS) measured is the patient's FEV1. The largest FEV1 sometimes comes from a different trial than the largest FVC.
