Which statement is true regarding ventilation?

a. Hypoventilation causes hypocapnia.
b. Hyperventilation causes hypercapnia.
c. Hyperventilation causes hypocapnia.
d. Hyperventilation results in an increased partial pressure of arterial carbon dioxide (PaCO2).

ANS: C
Hyperventilation is alveolar ventilation that exceeds metabolic demands. The lungs remove carbon dioxide at a faster rate than produced by cellular metabolism, resulting in decreased PaCO2 or hypocapnia.

Pulmonary edema and pulmonary fibrosis cause hypoxemia by which mechanism?

a. Creating alveolar dead space
b. Decreasing the oxygen in inspired gas
c. Creating a right-to-left shunt
d. Impairing alveolocarpillary membrane diffusion

ANS: D
Diffusion of oxygen through the alveolocapillary membrane is impaired if the alveolocapillary membrane is thickened or if the surface area available for diffusion is decreased. Abnormal thickness, as occurs with edema (tissue swelling) and fibrosis (formation of fibrous lesions), increases the time required for diffusion across the alveolocapillary membrane

Which condition is capable of producing alveolar dead space?

a. Pulmonary edema
b. Pulmonary emboli
c. Atelectasis
d. Pneumonia

ANS: B
A pulmonary embolus that impairs blood flow to a segment of the lung results in an area where alveoli are ventilated but not perfused, which causes alveolar dead space.

Which pleural abnormality involves a site of pleural rupture that acts as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing during expiration?

a. Spontaneous pneumothorax
b. Tension pneumothorax
c. Open pneumothorax
d. Secondary pneumothorax

ANS: B In tension pneumothorax, the site of pleural rupture acts as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing up during expiration. As more and more air enters the pleural space, air pressure in the pneumothorax begins to exceed barometric pressure.
