NR 302 Exam 2 Questions and 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?
