MULTIPLE CHOICE

1. A client is diagnosed with an inability to recognize visual information. The nurse realizes that which of the following cranial nerves is involved in the transmitting of visual stimuli to the brain for interpretation?
1.
CN II
2.
CN III
3.
CN IV
4.
CN VI

ANS: 1
The optic nerve is the second cranial nerve and is responsible for the transmitting of visual stimuli. Cranial Nerves III, IV, and VI control extraocular eye movements.

PTS: 1 DIF: Analyze REF: Anatomy and Physiology of the Eye

2. A client is diagnosed with a vision disorder. The nurse realizes that the client will experience an alteration in sensory information because the eyes transmit what percentage of all sensory information to the brain?
1.
30%
2.
50%
3.
70%
4.
90%

ANS: 3
Approximately 70% of all sensory information reaches the brain through the eyes.The other percentages are incorrect.

PTS: 1 DIF: Analyze REF: Anatomy and Physiology of the Eye

3. The nurse is performing an assessment on a client. To test the optic nerve’s function, what should the nurse do?
1.
Check for extraocular movement.
2.
Check the pupils for reaction to light.
3.
Check to see if the patient can blink.
4.
Use a Snellen chart.

ANS: 4
A Snellen chart is used to assess visual acuity of the optic nerve. Extraocular movements assess cranial nerves III, IV, and VI. Pupil reaction to light and eye blinking are not functions of the optic nerve.

PTS: 1 DIF: Apply REF: Assessment of the Eye

4. The nurse realizes that a client, diagnosed with chronic dry eyes, may have a disorder of the lacrimal gland because it:
1.
covers the eye for protection.
2.
produces tears to lubricate the eye.
3.
helps the eye keep its shape.
4.
provides blood to the eye.

ANS: 2
The lacrimal gland moistens the eye by producing and distributing tears to lubricate the eye. The lacrimal gland does not cover the eye for protection, help the eye keep its shape, or provide blood to the eye.

PTS: 1 DIF: Analyze REF: External Eye
