Answer to Question 1

A, C, D, E
All options listed are important teaching points for cast care except blowing warm air into the cast. If itching occurs, cool air will be most helpful.

Answer to Question 2

B
The tonometer reads the pressure exerted by the aqueous humor in the anterior chamber. The sclera is the part of the eyeball that is opaque white and covers the posterior portion of the eye-ball. The vitreous humor is the substance found in the posterior chamber of the eye between the lens and the retina. The cornea is a transparent structure in the eye that allows light to hit the lens. It is involved in the bending of light rays.
