Health Assessment Jarvis Ch 15: Eyes questions
with verified answers
9. A mother asks when her newborn infant's 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." Ans✓✓✓C. "By approximately 3 months of age, infants develop
more coordinated eye movements and can fixate on an object."
Eye movements may be poorly coordinated at birth, but by 3 to 4
months of age, the infant should establish binocularity and should be
able to fixate simultaneously on a single image with both eyes.
A 2-week-old infant can fixate on an object but cannot follow a light or
bright toy. The nurse would:
a. Consider this a normal finding.
b. Assess the pupillary light reflex for possible blindness.
c. Continue with the examination, and assess visual fields.
,d. Expect that a 2-week-old infant should be able to fixate and follow an
object. Ans✓✓✓A. Consider this a normal finding.
By 2 to 4 weeks an infant can fixate on an object. By the age of 1 month,
the infant should fixate and follow a bright light or toy.
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.
d. Know that floaters are usually insignificant and are caused by
condensed vitreous fibers. Ans✓✓✓D. Know that floaters are usually
insignificant and are caused by condensed vitreous fibers.
Floaters are a common sensation with myopia or after middle age and
are attributable to condensed vitreous fibers. Floaters or spots are not
usually significant, but the acute onset of floaters may occur with retinal
detachment.
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 individual's near vision.
c. Observe the distance between the palpebral fissures.
d. Perform the corneal light test, and look for symmetry of the light
reflex. Ans✓✓✓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.
A 68-year-old woman is in the eye clinic for a checkup. She tells the
nurse that she has been having trouble reading the paper, sewing, and
even seeing the faces of her grandchildren. On examination, the nurse
notes that she has some loss of central vision but her peripheral vision is
normal. These findings suggest that she may have:
a. Macular degeneration.
b. Vision that is normal for someone her age.
c. The beginning stages of cataract formation.
d. Increased intraocular pressure or glaucoma. Ans✓✓✓A. Macular
degeneration.
Macular degeneration is the most common cause of blindness. It is
characterized by the loss of central vision. Cataracts would show lens
opacity. Chronic open-angle glaucoma, the most common type of
