Answer to Question 1

D
Alveolar-capillary membrane function is measured by the pulmonary diffusion capacity of the carbon monoxide test. A very small amount of carbon monoxide (CO) is inhaled by the patient to perform the test. But the CO level is not measured in the blood, and CO is not removed from the blood.

Answer to Question 2

C
Chest radiology findings will include, but are not limited to, retraction of lung segments secondary to fibrosis and scarring and right-sided heart enlargement due to cor pulmonale.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
