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.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
