A 20-year-old patient is experiencing difficulty with near vision. The nurse realizes that this finding is:
 
  1. consistent with the aging process.
  2. normal in a 20-year-old patient.
  3. evidence of presbyopia.
  4. evidence of hyperopia.

Question 2

While exiting a burning building, a patient's eyebrows and lashes were burned. The nurse recognizes that this patient might experience:
 
  1. wound infections.
  2. fluid and electrolyte imbalance.
  3. foreign bodies in the eyes.
  4. itchiness as the hair grows back.

Question 3

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 4

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.
  4. peripheral vision and color perception.

Question 5

A patient with an injury to the right eye has received an eye patch. The nurse understands that this patient might experience difficulty with:
 
  1. depth perception.
  2. reading.
  3. light perception.
  4. color perception.

The answer to question 1

Correct Answer: 4
Changes in near vision, especially in patients over 45, can indicate presbyopia, which is impaired near vision that results from a loss of elasticity of the lens related to aging. In younger patients, this condition is referred to as hyperopia or farsightedness. This is not a normal finding in a 20-year-old.

The answer to question 2

Correct Answer: 3
The eyebrows shade the eyes and prevent perspiration from entering the eyes. When stimulated, the eyelashes cause the blink reflex, which serves to protect the eyes from foreign bodies. The lack of eyelashes and eyebrows would not increase risk of wound infection or lead to fluid and electrolyte imbalance. Some discomfort might be experienced as the hair grows back, but this is a minor concern compared to another possibility.

The answer to question 3

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.

The answer to question 4

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.

The answer to question 5

Correct Answer: 1
Depth perception depends on visual input from two eyes that function well. Reading may be contraindicated if the treatment plan warns against moving the eyes. Light and color will still be discernible to the good eye.
