c. By approximately 3 months of age, infants develop more coordinated eye movements and
can fixate on an object.

physiologic changes is responsible for presbyopia?
a. Degeneration of the cornea
b. Loss of lens elasticity
c. Decreased adaptation to darkness
d. Decreased distance vision abilities - ANSWER: b. Loss of lens elasticity
11. Which of these assessment findings would the nurse expect to see when examining the
eyes of a black patient?
a. Increased night vision
b. Dark retinal background
c. Increased photosensitivity
d. Narrowed palpebral fissures - ANSWER: b. Dark retinal background
An ethnically based variability in the color of the iris and in retinal pigmentation exists, with
darker irides having darker retinas behind them.
12. A 52-year-old patient describes the presence of occasional floaters or spots moving in
front of his eyes. The nurse should:
a. Examine the retina to determine the number of floaters.
b. Presume the patient has glaucoma and refer him for further testing.

ANSWER: d. Know that floaters are usually insignificant and are caused by condensed
vitreous fibers.
The nurse is preparing to assess the visual acuity of a 16-year-old patient. How should the
nurse proceed?
,a. Perform the confrontation test.
b. Ask the patient to read the print on a handheld Jaeger card.
c. Use the Snellen chart positioned 20 feet away from the patient.
d. Determine the patients ability to read newsprint at a distance of 12 to 14 inches. -
ANSWER: c. Use the Snellen chart positioned 20 feet away from the patient.
A patients vision is recorded as 20/30 when the Snellen eye chart is used. The nurse interprets
these results to indicate that:
a. At 30 feet the patient can read the entire chart.
b. The patient can read at 20 feet what a person with normal vision can read at 30 feet.
c. The patient can read the chart from 20 feet in the left eye and 30 feet in the right eye.
d. The patient can read from 30 feet what a person with normal vision can read from 20 feet.
- ANSWER: b. The patient can read at 20 feet what a person with normal vision can read
at 30 feet.
The top number indicates the distance the person is standing from the chart; the denominator
gives the distance at which a normal eye can see.
A patient is unable to read even the largest letters on the Snellen chart. The nurse should take
which action next?
a. Refer the patient to an ophthalmologist or optometrist for further evaluation.
b. Assess whether the patient can count the nurses fingers when they are placed in front of his
or her eyes.
c. Ask the patient to put on his or her reading glasses and attempt to read the Snellen chart
again.
d. Shorten the distance between the patient and the chart until the letters are seen, and record
that distance. - ANSWER: d. Shorten the distance between the patient and the chart until
the letters are seen, and record that distance.
A patients vision is recorded as 20/80 in each eye. The nurse interprets this finding to mean
that the patient:
a. Has poor vision.
b. Has acute vision.
c. Has normal vision.
, d. Is presbyopic. - ANSWER: a. Has poor vision.
The nurse is performing the diagnostic positions test. Normal findings would be which of
these results?
a. Convergence of the eyes
b. Parallel movement of both eyes
c. Nystagmus in extreme superior gaze
d. Slight amount of lid lag when moving the eyes from a superior to an inferior position -
ANSWER: b. Parallel movement of both eyes
A 60-year-old man is at the clinic for an eye examination. The nurse suspects that he has
ptosis of one eye. How should the nurse check for this?
a. Perform the confrontation test.
b. Assess the individuals near vision.
c. Observe the distance between the palpebral fissures.
d. Perform the corneal light test, and look for symmetry of the light reflex. - ANSWER: c.
Observe the distance between the palpebral fissures.
Ptosis is a drooping of the upper eyelid that would be apparent by observing the distance
between the upper and lower eyelids. The confrontation test measures peripheral vision.
Measuring near vision or the corneal light test does not check for ptosis.
22. When assessing the pupillary light reflex, the nurse should use which technique?
a. Shine a penlight from directly in front of the patient, and inspect for pupillary constriction.
b. Ask the patient to follow the penlight in eight directions, and observe for bilateral pupil
constriction.
c. Shine a light across the pupil from the side, and observe for direct and consensual pupillary
constriction.
d. Ask the patient to focus on a distant object. Then ask the patient to follow the penlight to
approximately 7 cm from the nose. - ANSWER: c. Shine a light across the pupil from the
side, and observe for direct and consensual pupillary constriction.
The nurse is assessing a patients eyes for the accommodation response and would expect to
see which normal finding?
