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.

Pink eye is a term that refers to conjunctivitis, which is inflammation of the thin, clear membrane (conjunctiva) over the white part of the eye (sclera). It may be triggered by a virus, bacteria, or foreign body in the eye.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
