NR-302 Exam 2 Review Questions with Correct
Answers
When examining the eye, the nurse notices that the patients eyelid margins approximate
completely. The nurse recognizes that this assessment finding:
Is expected
- The palpebral fissure is the elliptical open space between the eyelids, and, when closed, the
lid margins approximate completely, which is a normal finding.
During ocular examinations, the nurse keeps in mind that movement of the extraocular
muscles is:
Stimulated by CNs III, IV, and VI
- Movement of the extraocular muscles is stimulated by three CNs: III, IV, and VI.
The nurse is performing an external eye examination. Which statement regarding the
outer layer of the eye is true?
The outer layer of the eye is very sensitive to touch.
- The cornea and the sclera make up the outer layer of the eye. The cornea is very sensitive to
touch. The middle layer, the choroid, has dark pigmentation to prevent light from reflecting
internally. The trigeminal nerve (CN V) and the facial nerve (CN VII) are stimulated when
the outer surface of the eye is stimulated. The retina, in the inner layer of the eye, is where
light waves are changed into nerve impulses.
When examining a patients eyes, the nurse recalls that stimulation of the sympathetic
branch of the autonomic nervous system:
Elevates the eyelid and dilates pupil
,The nurse is reviewing causes of increased intraocular pressure. Which of these factors
determines intraocular pressure?
Amount of aqueous produced resistance to its outflow at the angle of the anterior chamber
The nurse is conducting a visual examination. Which of these statements regarding
visual pathways and visual fields is true?
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?
Pupillary constriction when looking at a near object
A patient has a normal pupillary light reflex. The nurse recognizes that this reflex
indicates that:
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:
By approximately 3 months of age, infants develop more coordinated eye movements and can
fixate on an object.
The nurse is reviewing in age-related changes in the eye for a class. Which of these
physiologic changes is responsible for presbyopia?
Loss of lens elasticity
- The lens loses elasticity and decreases its ability to change shape to accommodate for near
vision. This condition is called presbyopia
,Which of these assessment findings would the nurse expect to see when examining the
eyes of a black patient?
Dark retinal background
A 52-year-old patient describes the presence of occasional floaters or spots moving in
front of his eyes. The nurse should:
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?
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:
The patient can read at 20 feet what a person with normal vision can read at 30 feet.
A patient is unable to read even the largest letters on the Snellen chart. The nurse
should take which action next?
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:
Has poor vision
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:
Consider this a normal finding
, The nurse is performing the diagnostic positions test. Normal findings would be which
of these results?
Parallel movement of both eyes
During an assessment of the sclera of a black patient, the nurse would consider which of
these an expected finding?
Presence of small brown macules on the sclera
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?
Observe the distance between the palpebral fissures.
During an examination of the eye, the nurse would expect what normal finding when
assessing the lacrimal apparatus?
Absence of drainage from the puncta when pressing against the inner orbital rim
When assessing the pupillary light reflex, the nurse should use which technique?
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?
Convergence of the axes of the eyes
In using the ophthalmoscope to assess a patients eyes, the nurse notices a red glow in the
patients pupils. On the basis of this finding, the nurse would:
Consider the red glow a normal reflection of the ophthalmoscope light off the inner retina.
