1Lung Volumes
- ATidal volume is the amount of air inhaled with a normal breath from the resting level - about 500 ml
- BIRV - The max amount of additional air that can be inhaled beyond the tidal volume
- CERV - the max amount of air that can be exhaled following a normal exhalation from the resting level
- DResidual volume - the amount of air that remains after a normal expiration
- E1,2,3 are correct
- Fall are correct
2Lung Capacities which of the following is not true
- ATLC and FRC are 2 capacities with RV as part of the capacities
- BVC and IC are 2 capacities without RV
- CTLC = VC + RV
- DFRC = IRV + RV
3Elastic recoil of chest wall and lungs determines FRC
- AVerdadero
- BFalso
4Regarding FRC all are true except
- AIs what remains after a normal breath
- BFRC can be measured by spirometry
- CFRC increases with age
- DFRC decreases with lying down
5With age all of the following are true except?
- AIncreased RV
- BIncreased FRC
- CIncreased VC
- DNone of the above
6Lying down decreases FRC, VC is unchanged because of increased IRV
- AVerdadero
- BFalso
7In pregnancy all of the following changes are true except?
- ADecreased ERV
- BDecreased RV
- Cdecreased FRC
- Ddecreased Tidal volume
8Which of the following is the most reliable spirometry measurement
- AFVC
- BFEV1
- CFEF 25-75
- Dall of the above
9Highest airway resistance is seen in the mid sized bronchi
- AVerdadero
- BFalso
10Men have greater lung capacity and volume than women, but both sexes have equal tidal volumes
- AVerdadero
- BFalso
11all of the following are correctly matched except
- Anormal spirogram
- BCOPD
- CRestrictive lung disease
- DTracheal stenosis (fixed large airway)
- EVariable intrathoracic obstruction
- FVariable extrathoracic obstruction
- GNone of the above
- Anormal spirogram
12In Obstructive lung disease all are true except?
- AFEV1 is decreased
- BFVC is decreased
- CFEV1/FVC is increased
13In restrictive lung disease all are true except
- AFEV1 is decreased
- BFVC is increased
- CFEV1/FVC is increased
14Methacholine challenge test differentiates between bronchial asthma and the other obstructive lung diseases like chronic bronchitis and emphysema
- AVerdadero
- BFalso
15All of the following are restrictive lung diseases except?
- AIntrinsic lung diseases like interstitial fibrosis of lung or pneumonia
- BExtrinsic lung diseases that mechanically compress the lungs and limit their expansion
- CNeuromuscular diseases of the respiratory muscles
- Dnone of the above
16TLC
- ACan be measured by Gas dilution method
- BOr by body plethysmography
- CGas dilution method under estimates trapped gas
- Dif TLC pleth/TLC gas dilution is > 1,2 trapped gas is present
- Eall of the above are correct
17Diffusing capacity (Dl CO)
- ADecreased in emphysema (obstructive lung disease)
- Bdecreased in interstitial lung disease (restrictive lung disease)
- CIncreased in asthma (obstructive lung disease) - due to increased blood flow to lung
- Dused to distinguish between intrinsic lung disease from extrinsic lung disease
- Eall of the above are correct
