A nurse dorsiflexes a patient's right ankle 90 degrees and then uses a reflex hammer to strike
the appropriate tendon. What is the expected response for this deep tendon reflex?
a. Extension of the right lower leg
b. Plantar flexion of the right toes
c. Dorsiflexion of the right foot
d. Plantar flexion of the right foot - ANS :ANS: D
Feedback
A This is the expected response for the patellar deep tendon reflex.

B This is the expected response for the plantar reflex (Babinski).
C This is an incorrect response because the nurse is holding the patient's foot in dorsiflexion,
therefore dorsiflexion would not be an expected response.
D Plantar flexion is the expected response of the Achilles deep tendon reflex.
The nurse moves a wisp of cotton lightly across the anterior scalp, paranasal sinuses, and lower
jaw to test the function of which cranial nerve?
a. CN IV (trochlear nerve)
b. CN V (trigeminal nerve)
c. CN VI (abducens nerve)
d. CN VII (facial nerve) - ANS :ANS: B
Feedback
A The CN IV (trochlear nerve) supplies downward and inward eye movement.
B The CN V (trigeminal cranial nerve) supplies sensation to the cornea, iris, lacrimal glands,
conjunctiva, eyelids, forehead, nose, nasal and mouth mucosa, teeth, tongue, ear, and facial
skin.
C The CN VI (abducens nerve) supplies lateral eye movement.
D The CN VII (facial nerve) supplies movement of facial expression muscles except the jaw,
closes the eyes, and allows labial speech sounds (b, m, w, and rounded vowels).
A nurse who is assessing a patient's eyes finds that the pupils are equal, round, and react to
light and accommodation (PERRLA). These findings verify the expected functioning of which
cranial nerve?
a. Optic cranial nerve (CN II)
b. Oculomotor cranial nerve (CN III)

c. Trochlear cranial nerve (CN IV)
d. Abducens cranial nerve (CN VI) - ANS :ANS: B
Feedback
A The optic cranial nerve (CN II) provides vision.
B The oculomotor cranial nerve (CN III) provides these eye functions.
C The trochlear cranial nerve (CN IV) provides eye movement downward and inward.
D The abducens cranial nerve (CN VI) provides lateral eye movement.
In assessing a patient with a tumor in the pons, the nurse expects to find which abnormalities
due to pressure on cranial nerves?
a. Dilated pupils and ptosis
b. Facial asymmetry and impaired hearing
c. Difficulty swallowing
d. Impaired gag reflex - ANS :ANS: B
Feedback
A These abnormalities represent pressure on the oculomotor (CN III) that exits from the
midbrain.
B These abnormalities represent pressure on the facial and acoustic cranial nerves. The nurse
correlates the cranial nerves that exit from the pons which are trigeminal (CN V), abducens (CN
VI), facial (CN VII), and acoustic (CN VIII).
C This abnormality represents pressure on the three cranial nerves that affect swallowing:
glossopharyngeal (CN IX), vague (CN X), and hypoglossal (CN XII). These cranial nerves exit the
brainstem in the medulla oblongata.

D This reflex is controlled by the vagus cranial nerve (CN IX), which exits the brainstem in the
medulla oblongata.
The nurse assesses the glossopharyngeal nerve (CN IX) by testing which reflex?
a. Corneal reflex
b. Gag reflex
c. Blink reflex
d. Cough reflex - ANS :ANS: B
Feedback
A The corneal reflex is controlled by the trigeminal cranial nerve (CN V).
B Movement of the posterior pharynx and gag reflex test is controlled by the glossopharyngeal
cranial nerve (CN IX).
C The blink reflex is another name for the corneal reflex.
D The cough reflex is controlled from the medulla oblongata.
Which cranial nerve is assessed when a nurse asks a patient to stick out the tongue and move it
side to side?
a. Vagus nerve (CN X)
b. Facial nerve (CN VII)
c. Abducens nerve (CN VI)
d. Hypoglossal nerve (CN XII) - ANS :ANS: D
