5000 milliliters per minute
36,000 milliliters per minute
48,000 milliliters per minute

The amount of air that can be forcefully exhaled after a normal tidal volume exhalation is called the ________.
inspiratory reserve
expiratory reserve
vital capacity
tidal volume
expiratory reserve
To measure forced vital capacity (FVC) and forced expiratory volume (FEVT), the subject should ________.
take a deep inspiration, then calmly and carefully exhale as much air as possible
exhale as much air as possible, then inhale as much air as possible
take a deep inspiration, then rapidly and forcefully exhale as much air as possible
take a deep inspiration, then rapidly and forcefully exhale as much air as possible
Atelectasis is a collapsed lung. Explain how a pneumothorax might result in a collapsed lung and what should be done to restore the negative pressure of the pleural cavity.
A pneumothorax occurs when fluid builds up in a lung and causes the lung to rupture. Restoring lung function requires draining the fluid from the chest cavity.
A pneumothorax occurs when the pleura is punctured, and air becomes trapped in the thoracic cavity, the resulting pressure collapses the lung. To restore the negative pressure, an incision through the chest wall is made to release the air.
A pneumothorax occurs when the thoracic cavity is punctured, allowing air to enter the chest cavity and collapse the lung. Oxygen therapy is used to reinflate the lung.
Lung cancer can result in a pneumothorax if the tumor ruptures the pleura membrane. Surgery is required to remove the tumor and repair the pleura.
A pneumothorax occurs when the pleura is punctured, and air becomes trapped in the thoracic cavity, the resulting pressure collapses the lung. To restore the negative pressure, an incision through the chest wall is made to release the air.
Pectus excavatum is a condition in which the anterior thoracic cage is caved inward because of abnormal development of the sternum and ribs. What effect would you expect this condition to have on vital capacity, and why? Vital capacity will increase because the sunken chest creates more lung surface area. Vital capacity will decrease because the tidal volume is lower. Vital capacity is not affected by pectus excavatum because vital capacity is dependent on lung size and is not affected by the shape of the ribcage Vital capacity will decrease because the deformed ribcage limits the volume of air that can be inhaled.Vital capacity will decrease because the deformed ribcage limits the volume of air that can be inhaled.The vital capacity, or maximal amount of air that one can move, is the sum of ________. inspiratory capacity and functional residual capacity inspiratory capacity and residual volume inspiratory capacity and residual volume inspiratory reserve volume, tidal volume, and expiratory reserve volumeinspiratory reserve volume, tidal volume, and expiratory reserve volumeIn testing a patient who has tuberculosis, you would expect that the ________. FVC will be increased FVC will be decreasedFVC will be decreased
