Pulmonary function tests

Question 1

The amount of air inhaled or exhaled during normal breathing is 
A) Forced residual capacity
B) Tidal volume
C) Minute volume 
D) None of the above

Answer 1

Answer: B 
Tidal volume (VT) is the amount of air inhaled or exhaled during normal breathing.

Question 2

The total amount of air exhaled per minute is...
A) Tidal Volume
B) Residual Volume
C) Total lung capacity
D) None of the above

Answer 2

Answer: D. None of the above. 
Minute volume (MV) is the total amount of air exhaled per minute.

Question 3

The total volume of air that can be exhaled after inhaling as much as you can is...
A) Vital capacity
B) Minute expiratory volume
C) Total lung capacity 
D) None of the above

Answer 3

Answer: A Vital capacity
Vital capacity (VC) is the total volume of air that can be exhaled after inhaling as much as you can.

Question 4

What is the fastest rate that you can force air out of your lungs?
A) Forced Expiratory Flow (FEF)
B) Forced expiratory volume (FEV)
C) Peak expiratory flow rate (PEFR)
D) Forced vital capacity (FVC)

Answer 4

Answer: C

Peak expiratory flow rate (PEFR) is the fastest rate that you can force air out of your lungs.

Question 5

What is the amount of air left in lungs after exhaling normally?
A) Forced vital capacity (FVC)
B) Total lung capacity
C) Residual volume
D) Functional residual capacity (FRC)

Answer 5

Answer: D

Functional residual capacity (FRC) is the amount of air left in lungs after exhaling normally.

Question 6

What is the amount of air left in the lungs after exhaling as much as you can?
A) Tidal volume
B) Functional volume
C) Residual volume
D) None of the above

Answer 6

Answer: C

Residual volume is the amount of air left in the lungs after exhaling as much as you can

Question 7

What is the total volume of the lungs when filled with as much air as possible?
A) Total lung capacity
B) Minute expiratory volume
C) Residual volume
D) Peak expiratory flow rate

Answer 7

Answer: A

Total lung capacity. This is the total volume of the lungs when filled with as much air as possible.

Question 8

Forced vital capacity is what?
A) The total volume of air exhaled
B) The amount of air exhaled forcefully and quickly after inhaling as much as you can
C) The amount of air expired during the first, second, and third seconds of the FVC test
D) The fastest rate that you can force air out of your lung

Answer 8

Answer: B

Forced vital capacity (FVC) is the amount of air exhaled forcefully and quickly after inhaling as much as you can

Question 9

Forced expiratory volume (FEV) is what?
A) The amount of air expired during the first, second, and third seconds of the FVC test
B) The amount of air inhaled or exhaled during normal breathing.
C) The total volume of air that can be exhaled after inhaling as much as you can
D)The total amount of air exhaled per minute.

Answer 9

Answer: A
Forced expiratory volume (FEV). This is the amount of air expired during the first, second, and third seconds of the FVC test.

Question 10

Forced expiratory flow (FEF) is what?
A) The amount of air inhaled or exhaled during normal breathing.
B) The fastest rate that you can force air out of your lungs.
C) The total volume of the lungs when filled with as much air as possible.
D) The average rate of flow during the middle half of the FVC test.

Answer 10

Answer: D

Forced expiratory flow (FEF). This is the average rate of flow during the middle half of the FVC test.
