Chapter 14: Eyes
Jarvis: Physical Examination & Health Assessment, 7th Edition
MULTIPLE CHOICE
1. When examining the eye, the nurse notices that the patient’s 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.
DIF: Cognitive Level: Understanding (Comprehension) REF: p. 281
MSC: Client Needs: Physiologic Integrity: Physiologic Adaptation
2. During ocular examinations, the nurse keeps in mind that movement of the
extraocular muscles is:
a. Decreased in the older adult.
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.
DIF: Cognitive Level: Remembering (Knowledge) REF: p. 283
MSC: Client Needs: Physiologic Integrity: Physiologic Adaptation
,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.
DIF: Cognitive Level: Understanding (Comprehension) REF: p. 283
MSC: Client Needs: Physiologic Integrity: Physiologic Adaptation
, 4. When examining a patient’s eyes, the nurse recalls that stimulation of the
sympathetic branch of the autonomic nervous system:
a. Causes pupillary constriction.
b. Adjusts the eye for near vision.
c. Elevates the eyelid and dilates the pupil.
d. Causes contraction of the ciliary body.
ANS: C
Stimulation of the sympathetic branch of the autonomic nervous system dilates
the pupil and elevates the eyelid. Parasympathetic nervous system stimulation
causes the pupil to constrict. The muscle fibers of the iris contract the pupil in
bright light to accommodate for near vision. The ciliary body controls the
thickness of the lens.
DIF: Cognitive Level: Understanding (Comprehension) REF: p. 283
MSC: Client Needs: Physiologic Integrity: Physiologic Adaptation
5. The nurse is reviewing causes of increased intraocular pressure. Which of
these factors determines intraocular pressure?
