A 29-year-old African American female was diagnosed with schizophrenia
approximately three years ago. After many trials of antipsychotics, she was finally
stabilized on haloperidol during the past six months. Three weeks ago she began
exhibiting mild pseudo-Parkinson's symptoms.
Which class of medications would be most appropriate for treating these side effects?
Muscarinic 1 antagonist
Histamine 1 antagonist
Alpha 1 adrenergic agonist
Cholinesterase inhibitor - ANSWER - Correct answer: Muscarinic 1 antagonist
Extrapyramidal symptoms are drug-induced side effects that affect motor functioning
and muscle movement. Extrapyramidal symptoms are associated with a deficiency of
dopamine and an excess of acetylcholine in the nigrostriatal pathway. A common type
of extrapyramidal symptom is called pseudo-Parkinson's, which presents with a
shuffling gait, motor slowing, mask-like facial expression, tremors, and muscle rigidity.
Muscarinic 1 antagonist medications reduce the effects of excess acetylcholine and
relieve extrapyramidal symptoms.

As a nurse practitioner, you are responsible for assessing cranial nerves as a part of the
neurological exam. What cranial nerve assessment tests hearing?
Oculomotor nerve (CN III)
Trochlear nerve (CN IV)
Vestibulocochlear nerve (CN VIII)
Trigeminal nerve (CN V) - ANSWER - Correct answer: Vestibulocochlear nerve (CN
VIII)
Olfactory nerve (CN I)
The olfactory nerve transmits information to the brain regarding a person's sense of
smell. This cranial nerve assessment is performed by having the client close their eyes
to identify familiar odors.
Optic nerve (CN II)
The optic nerve transmits information to the brain regarding a person's vision.
Oculomotor nerve (CN III)
The oculomotor nerve helps control muscle movements of the eyes. The oculomotor
nerve provides movement to most of the muscles that move the eyeball and upper
, eyelid, known as extraocular muscles. The oculomotor nerve also helps with involuntary
functions of the eye.
Trochlear nerve (CN IV)
The trochlear nerve is also involved in eye movement. The trochlear nerve, like the
oculomotor nerve, originates in the midbrain. It powers the contralateral superior oblique
muscle that allows the eye to point downward and inward.
Trigeminal nerve (CN V)
The trigeminal nerve is the largest cranial nerve and has both motor and sensory
functions. Its motor functions help a person to chew and clench the teeth and gives
sensation to muscles in the tympanic membrane of the ear. This test is performed by
touching the face and corneal reflex of the eye with a wisp of cotton and pin-pricking the
skin and mucosa to test touch.
Abducens nerve (CN VI)
The abducens nerve also helps control eye movements. It helps the lateral rectus
muscle, which is one of the extraocular muscles, to turn the gaze outward.
Facial nerve (CN VII)
The facial nerve functions to produce facial expressions and has both motor and
sensory functions.
Vestibulocochlear nerve (CN VIII)
