a. 500 mL

b. 1000 mL

c. 2000 mL

d. 2500 mL

4) Which of the following represents the sum of vital capacity and residual volume?

a. IC + FRC

b. IRV + TV + ERV + RV

c. TLC

d. All of the above

5) Pulmonary function tests (PFT) that measure flow rates include

a. FEV₁

b. FEV₁/FVC ratio

c. FVC

d. All of the above

e. A and B only

Answer 1

Ans:-

1.

D,

Residual volume,

we can not measure residual volume with the help of the spirometry because there is no way of knowing the volume remaining in the lungs after a maximal expiration.

2.

C,

Moderate obstruction,

An FEV1 value of 70% indicates moderate obstruction.

3.

A,

500ml, is a normal tidal volume value.

4.

C,

TLC( total lung capacity), represents the sum of the vital capacity and residual volume.

TLC :- TV + IRV+ ERV+ RV,

AND Vital capacity:- TV+ IRV+ERV.

5.

D,

Pulmonary function tests that measure flow rates includes all of these:- FEV1, FVC And FEV1/ FVC.
