The nurse positions a patient for an eye examination. After repeated attempts, the patient is able to read all the letters on the Snellen chart without difficulty at a distance of 15 feet. From this finding the nurse determines that the patient:
 
  1. has normal 20/20 vision.
  2. has normal reading vision.
  3. has visual impairments.
  4. has a normal pupillary reflex.

Question 2

A patient has sustained an injury to the inner layer of the left retina. The nurse realizes that this patient will have difficulty with:
 
  1. tear production.
  2. blinking.
  3. reading.

Answer to Question 1

Correct Answer: 3
The patient must stand closer than normal to read the chart. For people with normal vision, the distance from the viewed object at which the eyes require no accommodation is 20 feet. This test is not used to assess reading vision or pupillary reflex.

Answer to Question 2

Correct Answer: 4
The retina is the innermost lining of the eyeball. It has a pigmented outer layer and an inner neural layer. The transparent inner layer is made up of millions of light receptors in structures called rods and cones. Rods enable vision in dim light as well as peripheral vision. Cones enable vision in bright light and the perception of color. Tear production and blinking are not controlled by the inner retina. Reading will still be possible with this type of injury.
