MULTIPLE CHOICE j
1. A patient with depression mentions to the nurse, My mother says depression is a
j j j j j j j j j j j j j
chemical disorder. What does she mean? The nurses response is based on the theory
j j j j j j j j j j j j j j
that depression primarily involves which of the following neurotransmitters?
j j j j j j j j j
a. Cortisol and GABA j j
b. COMT and glutamate j j
c. Monamine and glycine j j
d. Serotonin and norepinephrine j j
ANS: D j
One possible cause of depression is thought to involve one or more neurotransmitters.
j j j j j j j j j j j j
Serotonin and norepinephrine have been found to be important in the regulation of
j j j j j j j j j j j j j
depression. There is no research to support that the other options play a significant role
j j j j j j j j j j j j j j j
in the development of depression.
j j j j j
2. A patient has experienced a stroke (cerebral vascular accident) that has resulted in
j j j j j j j j j j j j
damage to the Broca area. Which evaluation does the nurse conduct to reinforce this
j j j j j j j j j j j j j j
diagnosis?
j
a. Observing the patient pick up a spoon j j j j j j
b. Asking the patient to recite the alphabet j j j j j j
c. Monitoring the patients blood pressure j j j j
d. Comparing the patients grip strength in both hands j j j j j j j
ANS: B j
Accidents or strokes that damage Brocas area may result in the inability to speak (i.e.,
j j j j j j j j j j j j j j
,motor aphasia). Fine motor skills, blood pressure control, and muscle strength are not
j j j j j j j j j j j j
controlled by the Broca area of the left frontal lobe.
j j j j j j j j j j
3. The patient diagnosed with schizophrenia asks why psychotropic medications are
j j j j j j j j j
always prescribed by the doctor. The nurses answer will be based on information that
j j j j j j j j j j j j j j
the therapeutic action of psychotropic drugs is the result of their effect on:
j j j j j j j j j j j j j
a. The temporal lobe; especially Wernickes area
j j j j j
b. Dendrites and their ability to transmit electrical impulses
j j j j j j j
c. The regulation of neurotransmitters especially dopamine
j j j j j
d. The peripheral nervous system sensitivity to the psychotropic medications
j j j j j j j j
,ANS: C j
Medications used to treat psychiatric disorders operate in and around the synaptic cleft
j j j j j j j j j j j j
and have action at the neurotransmitter level, especially in the case of schizophrenia, on
j j j j j j j j j j j j j j
dopamine. The Wernickes area, dendrite function, or the sensitivity of the peripheral
j j j j j j j j j j j j
nervous system are not relevant to either schizophrenia or psychotropic medications.
j j j j j j j j j j j
4. A student nurse mutters that it seems entirely unnecessary to have to strugglewith
j j j j j j j j j j j j j
understanding the anatomy and physiology of the neurologic system. The mentor
j j j j j j j j j j j
would base a response on the understanding that it is:
j j j j j j j j j j
Necessary but generally for psychiatric nurses who focus primarily on j j j j j j j j j
a. behavioral interventions j j
A complex undertaking that advance practice psychiatric nurses frequently use
j j j j j j j j j
b. in their practice
j j j
Important primarily for the nursing assessment of patients with brain traumacaused j j j j j j j j j j
c. cognitive symptoms
j j
Necessary for planning psychiatric care for all patients especially those j j j j j j j j j
d. experiencing psychiatric disorders
j j j
ANS: D j
Nurses must understand that many symptoms of psychiatric disorders have a
j j j j j j j j j j
neurologic basis, although the symptoms are manifested behaviorally. This
j j j j j j j j j
understanding facilitates effective care planning. The foundation of knowledge is not
j j j j j j j j j j j
used exclusively by advanced practice psychiatric nurses nor is it relevant for only
j j j j j j j j j j j j j
behavior therapies or brain trauma since dealing with the results of normal and
j j j j j j j j j j j j j
abnormal brain function is a responsibility of all nurses providing all types of care to
j j j j j j j j j j j j j j j
the psychiatric patient.

5. A patient asks the nurse, My wife has breast cancer. Could it be caused by her
j j j j j j j j j j j j j j j
chronic depression? Which response is supported by research data?
j j j j j j j j j
a. Too much stress has been proven to cause all kinds of cancer. j j j j j j j j j j j
b. There have been no research studies done on stress and disease yet.
j j j j j j j j j j j
c. Stress does cause the release of factors that suppress the immune system. j j j j j j j j j j j
d. There appears to be little connection between stress and diseases of the body j j j j j j j j j j j j
ANS: C j
Research indicates that stress causes a release of corticotropin-releasing factors that
j j j j j j j j j j
suppress the immune system. Studies indicate that psychiatric disorders such as mood
j j j j j j j j j j j j
disorders are sometimes associated with decreased functioning of the immune system.
j j j j j j j j j j j
Research does not support a connection between many cancers and stress. There is a
j j j j j j j j j j j j j j
significant amount of research about stress and the body. Research has shown that
j j j j j j j j j j j j j
there are some connections between stress and physical disease.
j j j j j j j j j
, 6. A patient who has a parietal lobe injury is being evaluated for psychiatric
j j j j j j j j j j j j
rehabilitation needs. Of the aspects of functioning listed, which will the nurse identify
j j j j j j j j j j j j j
as a focus of nursing intervention?
j j j j j j
a. Expression of emotion j j
b. Detecting auditory stimuli j j
c. Receiving visual images j j
d. Processing associations j
ANS: D j
The parietal lobe is responsible for associating and processing sensory information that
j j j j j j j j j j j
allows for functions such as following directions on a map, reading a clock, dressing
j j j j j j j j j j j j j j
self, keeping appointments, and distinguishing right from left. Emotional expression is
j j j j j j j j j j j
associated with frontal lobe function. Detecting auditory stimuli is a temporal lobe
j j j j j j j j j j j j
function. Receiving visual images is related to occipital lobe function.
j j j j j j j j j j
7. At admission, the nurse learns that some time ago the patient had an infarct in the
j j j j j j j j j j j j j j j
right cerebral cortex. During assessment, the nurse would expect to find that the
j j j j j j j j j j j j j
patient:
j
a. Demonstrates major deficiencies in speech j j j j
b. Is unable to effectively hold a spoon in the left hand
j j j j j j j j j j
c. Has difficulty explaining how to go about using the telephone
j j j j j j j j j
d. Cannot use his right hand to shave himself or comb his own hair j j j j j j j j j j j j
ANS: B j
The cerebral hemispheres are responsible for functions such as control of muscles. The
j j j j j j j j j j j j
right hemisphere mainly controls the motor and sensory functions on the left side of the
j j j j j j j j j j j j j j j
body. Damage to the right side would result in impaired function on the left side of the
j j j j j j j j j j j j j j j j j
body. The motor cortex controls voluntary motor activity. Brocas area controls motor
j j j j j j j j j j j j
speech. Cognitive functions are attributed to the association cortex.
j j j j j j j j j
The right side of the bodys motor activity is controlled by the left cerebral cortex.
j j j j j j j j j j j j j j
8. A patient with chronic schizophrenia had a stroke involving the hippocampus. The
j j j j j j j j j j j
patient will be discharged on low doses of haloperidol. The nurse will need to
j j j j j j j j j j j j j j
individualize the patients medication teaching by:
j j j j j j
a. Including the patients caregiver in the education j j j j j j
b. Being careful to stress the importance of taking the medication as prescribed
j j j j j j j j j j j
Providing the education at a time when the patient is emotionally calm and j j j j j j j j j j j j
c. relaxed
j
Encouraging the patient to crush or dissolve the medication to help with swallowing j j j j j j j j j j j j
d.
