Answer to Question 1

ANS: C
When the eye is examined, the light will reflect off the tumor, giving the eye a whitish appearance. This is called a cat's eye reflex. A late sign of retinoblastoma is a red, painful eye with glaucoma. Amblyopia, or lazy eye, is reduced visual acuity in one eye. The eye socket is not sunken.

Answer to Question 2

ANS: B
The nurse's role in a penetrating eye injury is to prevent further injury to the eye. A Fox shield (if available) should be applied to the injured eye and a regular eye patch to the other eye to prevent bilateral movement. It may cause more damage to the eye to apply a regular eye patch, apply ice until the physician is seen, or irrigate the eye copiously with a sterile saline solution.
