ATI HEALTH ASSESSMENT VERSION A
A nurse is examining the eyes of a client who has complained of
having a feeling of a foreign body in his eye. The nurse examines the
thin, transparent, continuous membrane that lines the inside of the
eyelids and covers most of the anterior eye. The nurse recognizes this
membrane as which of the following?
a) Cornea
b) Conjunctiva
c) Retina
d) Sclera - ...ANSWER...Conjunctiva
Explanation:
The conjunctiva is a thin, transparent, continuous membrane that is
divided into two portions: a palpebral and a bulbar portion. The
palpebral conjunctiva lines the inside of the eyelids, and the bulbar
conjunctiva covers most of the anterior eye, merging with the cornea
at the limbus. The innermost layer, the retina, extends only to the
ciliary body anteriorly. It receives visual stimuli and sends them to the
brain. The sclera is a dense, protective, white covering that physically
supports the internal structures of the eye. The transparent cornea (the
"window of the eye") permits the entrance of light, which passes
through the lens to the retina.
Which of the following findings should a doctor expect to note when
assessing the six cardinal fields of gaze?
a. The presence of nystagmus in all fields
,b. Symmetrical corneal light reflex
c. Presence of the red reflex
d. Smooth, coordinated movement of the eyes - ...ANSWER...
EXPLANATION: Smooth, coordinated movement of the eyes-the
six cardinal fields test eye movements and the muscle of the eye.
normal findings include smooth, coordinated movement of the eyes
with occasional mild nystagmus (jerking) in extreme lateral gaze.
nystagmus in all six fields is an abnormal finding that requires further
evaluation. a symmetrical corneal light reflex is the expected response
of the corneal light reflex test. the red reflex is assessed when using
the ophthalmoscope.
A nurse is presenting a class to a local community group about vision
and eye health. As part of the presentation, the nurse explains how
visual perception occurs. Which of the following would the nurse
include in the explanation?
a) It primarily involves the lens of the eye.
b) It allows the eyes to focus on near objects.
c) It begins with light rays striking the retina.
d) It refers to a client's subjective appraisal of his or her vision. -
...ANSWER...It begins with light rays striking the retina.
Explanation:
Visual perception occurs as light rays strike the retina, where they are
transformed into nerve impulses, conducted to the brain through the
optic nerve, and interpreted. The lens does not contribute directly to
visual perception. Accommodation is the process that allows the eyes
to focus on near objects.
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. - ...ANSWER...B
RATIONALE: The image formed on the retina is upside down and
reversed from its actual appearance in the outside world. The light
rays are refracted through the transparent media of the eye before
striking the retina, and the nerve impulses are conducted through the
optic nerve tract to the visual cortex of the occipital lobe of the brain.
The left side of the brain interprets vision for the right eye.
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. -
...ANSWER...D
EXPLANATION: The pupillary light reflex is the normal
constriction of the pupils when bright light shines on the retina. The
other responses are not correct.
In using the ophthalmoscope to assess a patient's eyes, the nurse
notices a red glow in the patient's pupils. On the basis of this finding,
the nurse would:
a.Suspect that an opacity is present in the lens or cornea.
b.Check the light source of the ophthalmoscope to verify that it is
functioning.
c.Consider the red glow a normal reflection of the ophthalmoscope
light off the inner retina.
d.Continue with the ophthalmoscopic examination, and refer the
patient for further evaluation. - ...ANSWER...C
EXPLANATION: The red glow filling the person's pupil is the red
reflex and is a normal finding caused by the reflection of the
ophthalmoscope light off the inner retina. The other responses are not
correct.
The nurse is examining a patient's retina with an ophthalmoscope.
Which finding is considered normal?
, a.Optic disc that is a yellow-orange color
b.Optic disc margins that are blurred around the edges
c.Presence of pigmented crescents in the macular area
d.Presence of the macula located on the nasal side of the retina -
...ANSWER...A
RATIONALE: The optic disc is located on the nasal side of the
retina. Its color is a creamy yellow-orange to a pink, and the edges are
distinct and sharply demarcated, not blurred. A pigmented crescent is
black and is due to the accumulation of pigment in the choroid.
When performing the corneal light reflex assessment, the nurse notes
that the light is reflected at 2 o'clock in each eye. The nurse should:
a.Consider this a normal finding.
b.Refer the individual for further evaluation.
c.Document this finding as an asymmetric light reflex.
d.Perform the confrontation test to validate the findings. -
...ANSWER...A
EXPLANATION: Reflection of the light on the corneas should be in
exactly the same spot on each eye, or symmetric. If asymmetry is
noted, then the nurse should administer the cover test.
The nurse is performing an eye-screening clinic at a daycare center.
When examining a 2-year-old child, the nurse suspects that the child
has a "lazy eye" and should:
a.Examine the external structures of the eye.
b.Assess visual acuity with the Snellen eye chart.
c.Assess the child's visual fields with the confrontation test.
d.Test for strabismus by performing the corneal light reflex test. -
...ANSWER...D
Testing for strabismus is done by performing the corneal light reflex
test and the cover test. The Snellen eye chart and confrontation test
are not used to test for strabismus.
Which of the following terms describes involuntary, jerking, rhythmic
movements of the eyes?
a. diplopia
b. exophthalmos
