Chapter 16. Eye
1. When examining the eye, the nurse notices that the patients eyelid margins
approximate completely. The nurse recognizes that this assessment finding:
a. Is expected.
b. May indicate a problem with extraocular
muscles. c. May result in problems with tearing.
d. Indicates increased intraocular pressure.
ANS: A
The palpebral fissure is the elliptical open space between the eyelids, and, when closed, the
lid margins approximate completely, which is a normal finding.
, 2. During ocular examinations, the nurse keeps in mind that movement of the
extraocular muscles is:
a. Decreased in the older child.
b. Impaired in a patient with cataracts.
c. Stimulated by cranial nerves (CNs) I and
II. d. Stimulated by CNs III, IV, and VI.
ANS: D
Movement of the extraocular muscles is stimulated by three CNs: III, IV, and VI.
3. The nurse is performing an external eye examination. Which statement regarding the
outer layer of the eye is true?
a. The outer layer of the eye is very sensitive to touch.
b. The outer layer of the eye is darkly pigmented to prevent light from
reflecting internally.
c. The trigeminal nerve (CN V) and the trochlear nerve (CN IV) are
stimulated when the outer surface of the eye is stimulated.
d. The visual receptive layer of the eye in which light waves are changed into
nerve impulses is located in the outer layer of the eye.
ANS: A
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.
4. When examining a patients eyes, the nurse recalls that stimulation of the sympathetic
branch of the autonomic nervous system:
a. Causes pupillary constriction.
