Answer to Question 1

ANS: A
The most common uses for MRI in the chest are for imaging the mediastinum, large vessels in the lung, and hilar regions of the lungs.

Answer to Question 2

ANS: B
It is critically important to avoid taking conventional metal objects near the MRI machine, be-cause the powerful magnet will pull the metallic object into the magnet with great force, exposing patients and health care providers in its path to life-threatening risk.

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.
