The nurse is conducting a visual examination. Which of these
statements regarding visual pathways and visual fields is true?
a. The right side of the brain interprets the vision for the
right eye.
b. The image formed on the retina is upside down and
reversed from its actual appearance in the outside world.
c. Light rays are refracted through the transparent media of
the eye before striking the pupil.
d. Light impulses are conducted through the optic nerve to
the temporal lobes of the brain. - CORRECT ANSWER-b. The
image formed on the retina is upside down and reversed from
its actual appearance in the outside world.
,The nurse is testing a patients visual accommodation, which
refers to which action?
a. Pupillary constriction when looking at a near object
b. Pupillary dilation when looking at a far object
c. Changes in peripheral vision in response to light
d. Involuntary blinking in the presence of bright light -
CORRECT ANSWER-a. Pupillary constriction when looking at a
near object
A patient has a normal pupillary light reflex. The nurse
recognizes that this reflex indicates that:
a. The eyes converge to focus on the light.
b. Light is reflected at the same spot in both eyes.
c. The eye focuses the image in the center of the pupil.
d. Constriction of both pupils occurs in response to bright
light. - CORRECT ANSWER-d. Constriction of both pupils
occurs in response to bright light.
,A mother asks when her newborn infants eyesight will be
developed. The nurse should reply:
a. Vision is not totally developed until 2 years of age.
b. Infants develop the ability to focus on an object at
approximately 8 months of age.
c. By approximately 3 months of age, infants develop more
coordinated eye movements and can fixate on an object.
d. Most infants have uncoordinated eye movements for the
first year of life. - CORRECT ANSWER-c. By approximately 3
months of age, infants develop more coordinated eye
movements and can fixate on an object.
10. The nurse is reviewing in age-related changes in the eye
for a class. Which of these 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 - CORRECT 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 - CORRECT 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.
c. Consider these to be abnormal findings, and refer him to an
ophthalmologist.
