MULTIPLE CHOICE
1. When a nurse administers medication that focuses on the management of Parkinsondisease,
what is the focus of the associated evaluation?
a. Spinal nerve function
b. The central nervous system
c. The sympathetic nervous system
d. The expected effects of dopamine
ANS: D
In Parkinson disease (PD), dopamine is reduced by death of dopamine releasing cells in the
substantia nigra. Without the excitatory effect of dopamine to the striatum, more pallidal firing
reduces thalamic activity. Cortical activating effects are reduced, with decline in initiating and
executing motor activity, causing bradykinesia, and disinhibition of muscular control, causing
resting tremor, rigidity, and loss of postural reflexes. Treatment efforts in PD are directed at
resupplying dopamine to the CNS via L-DOPA or providing dopamine antagonists. This drug
therapy does not affect spinal nerve function or function associated with the central or
sympathetic nervous systems.

2. A patient reports frequent episodes of rage. The nurse will assess which of thepatient‘s
physiological signs to help confirm an association of symptoms?
a. Blood pressure
b. Temperature
c. Respiratory rate
d. Respiratory depth
, ANS: B
Hypothalamic controls the body‘s homeostasis by hormonal release. It monitors sodium and
water balances, levels of oxygen in the bloodstream, body temperature, feeding and appetite,
thirst and fluid intake, growth, sexual development, thyroid and adrenal gland functioning,
lactation, rage, and emotional arousal. Research has not implicated any of the other physical
functions listed.

3. A patient is recovering from surgery to remove a tumor in the cerebellum. Which assessment
finding is most attributable to this diagnosis?
a. The patient reports of limited taste and smell.
b. The patient demonstrates poor balance and coordination.
c. The patient has limited ability to learn and poor memory.
d. The patient has poor emotional control and low motivation.
ANS: B
The cerebellum coordinates muscle synergy and is responsible for the maintenance of
equilibrium. The limbic system plays a role in taste, smell, memory, learning, emotional control,
and motivation.

, 4. The nurse plans discharge teaching for a patient who experienced a stroke involving the
hippocampus. The nurse should adapt the teaching plan to account for possible problems with
which function?
a. Visual acuity
b. Expressive aphasia
c. Short-term memory
d. Balance and coordination
ANS: C
The limbic system is crucial to memory. Damage to the hippocampus, a part of the limbic
system, causes problems converting short-term to long-term memory, making learning difficult.
Aphasia is a temporal lobe problem. Blindness is an occipital lobe problem. Balance and
coordination are affected by damage to the cerebellum.

5. A patient has had their corpus callosum surgical severed to treat intractable seizures. What effects
will the nurse educate the patient to possibly expect?
a. Old memory loss
b. Blindness
c. Hearing loss
d. Inability to learn new motor skills
ANS: D
When the corpus callosum is severed, as has been done in several instances for treatment of
intractable seizures, a phenomenon known as ―split brain syndrome‖ develops, confirming the
lateralization of functions between the hemispheres. After the procedure, actions performed
by one side are incomprehensible to the other. Although old memories and skills arepreserved by
each side, new tasks requiring communication between the sides, like learning to play a musical
instrument, are impossible to learn. Neither blindness nor hearing should be affected.
