Chapter 1 Chemical neurotransmission
MULTIPLE CHOICE
1. A patient with depression mentions to the nurse, My mother says depression is a
chemical disorder. What does she mean? The nurses response is based on the theory
that depression primarily involves which of the following neurotransmitters?
a. Cortisol and GABA
b. COMT and glutamate
c. Monamine and glycine
d. Serotonin and norepinephrine
ANS: D
One possible cause of depression is thought to involve one or more neurotransmitters.
Serotonin and norepinephrine have been found to be important in the regulation of
depression. There is no research to support that the other options play a significant
role in the development of depression.
2. A patient has experienced a stroke (cerebral vascular accident) that has resulted in
damage to the Broca area. Which evaluation does the nurse conduct to reinforce this
diagnosis?
a. Observing the patient pick up a spoon
b. Asking the patient to recite the alphabet
c. Monitoring the patients blood pressure
d. Comparing the patients grip strength in both hands
ANS: B
Accidents or strokes that damage Brocas area may result in the inability to speak (i.e.,
motor aphasia). Fine motor skills, blood pressure control, and muscle strength are not
controlled by the Broca area of the left frontal lobe.
3. The patient diagnosed with schizophrenia asks why psychotropic medications are
always prescribed by the doctor. The nurses answer will be based on information that
the therapeutic action of psychotropic drugs is the result of their effect on:
a. The temporal lobe; especially Wernickes area
b. Dendrites and their ability to transmit electrical impulses
c. The regulation of neurotransmitters especially dopamine
d. The peripheral nervous system sensitivity to the psychotropic medications

a. The temporal lobe; especially Wernickes area
b. Dendrites and their ability to transmit electrical impulses
c. The regulation of neurotransmitters especially dopamine
d. The peripheral nervous system sensitivity to the psychotropic medications
Medications used to treat psychiatric disorders operate in and around the synaptic cleft
and have action at the neurotransmitter level, especially in the case of schizophrenia,
on dopamine. The Wernickes area, dendrite function, or the sensitivity of the
peripheral nervous system are not relevant to either schizophrenia or psychotropic
medications.
4. A student nurse mutters that it seems entirely unnecessary to have to struggle with
understanding the anatomy and physiology of the neurologic system. The mentor
would base a response on the understanding that it is:
a.
Necessary but generally for psychiatric nurses who focus primarily on
behavioral interventions
b.
A complex undertaking that advance practice psychiatric nurses frequently use
in their practice
c.
Important primarily for the nursing assessment of patients with brain
traumacaused cognitive symptoms
d.
Necessary for planning psychiatric care for all patients especially those
experiencing psychiatric disorders
ANS: D
Nurses must understand that many symptoms of psychiatric disorders have a
neurologic basis, although the symptoms are manifested behaviorally. This
understanding facilitates effective care planning. The foundation of knowledge is not
used exclusively by advanced practice psychiatric nurses nor is it relevant for only
behavior therapies or brain trauma since dealing with the results of normal and
abnormal brain function is a responsibility of all nurses providing all types of care to
the psychiatric patient.
5. A patient asks the nurse, My wife has breast cancer. Could it be caused by her
chronic depression? Which response is supported by research data?
a. Too much stress has been proven to cause all kinds of cancer.
b. There have been no research studies done on stress and disease yet.
c. Stress does cause the release of factors that suppress the immune system.
d. There appears to be little connection between stress and diseases of the body
ANS: C
Research indicates that stress causes a release of corticotropin-releasing factors that
suppress the immune system. Studies indicate that psychiatric disorders such as mood
disorders are sometimes associated with decreased functioning of the immune system.
Research does not support a connection between many cancers and stress. There is a
significant amount of research about stress and the body. Research has shown that
there are some connections between stress and physical disease.
rehabilitation needs. Of the aspects of functioning listed, which will the nurse identify
as a focus of nursing intervention?
a. Expression of emotion
b. Detecting auditory stimuli
c. Receiving visual images
d. Processing associations
ANS: D
The parietal lobe is responsible for associating and processing sensory information
that allows for functions such as following directions on a map, reading a clock,
dressing self, keeping appointments, and distinguishing right from left. Emotional
expression is associated with frontal lobe function. Detecting auditory stimuli is a
temporal lobe function. Receiving visual images is related to occipital lobe function.
7. At admission, the nurse learns that some time ago the patient had an infarct in the
right cerebral cortex. During assessment, the nurse would expect to find that the
patient:
a. Demonstrates major deficiencies in speech
b. Is unable to effectively hold a spoon in the left hand
c. Has difficulty explaining how to go about using the telephone
d. Cannot use his right hand to shave himself or comb his own hair
ANS: B
The cerebral hemispheres are responsible for functions such as control of muscles.
The right hemisphere mainly controls the motor and sensory functions on the left side
of the body. Damage to the right side would result in impaired function on the left
side of the body. The motor cortex controls voluntary motor activity. Brocas area
controls motor speech. Cognitive functions are attributed to the association cortex.
The right side of the bodys motor activity is controlled by the left cerebral cortex.
8. A patient with chronic schizophrenia had a stroke involving the hippocampus. The
patient will be discharged on low doses of haloperidol. The nurse will need to
individualize the patients medication teaching by:
a. Including the patients caregiver in the education
b. Being careful to stress the importance of taking the medication as prescribed
c.
Providing the education at a time when the patient is emotionally calm and
relaxed
d.
Encouraging the patient to crush or dissolve the medication to help with
swallowing
ANS: A
Loading page 4...
Taking the medication as prescribed and providing the education at a time when the
patient is calm and relaxed is information or considerations that all patients should be
given. The medication does not necessarily need to be crushed or dissolved since the
stroke would not have caused difficulty with swallowing.
9. The physician tells the nurse, The medication Im prescribing for the patient
enhances the g-aminobutyric acid (GABA) system. Which patient behavior will
provide evidence that the medication therapy is successful?
a. The patient is actively involved in playing cards with other patients.
b. The patient reports that, I dont feel as anxious as I did a couple of days ago.
c. The patient reports that both auditory and visual hallucinations have decreased.
d. The patient says that, I am much happier than before I came to the hospital.
ANS: B
GABA is the principle inhibitory neurotransmitter. The medication should provide an
antianxiety effect. Alertness, psychotic behaviors, and mood elevation are not
generally affected by g-aminobutyric acid.
10. The patients family asks whether a diagnosis of Parkinsons disease creates an
increased risk for any mental health issues. What question would the nurse ask to
assess for such a comorbid condition?
a. Has your father exhibited any signs of depression?
b. Does your father seem to experience mood swings?
c. Have you noticed your father talking about seeing things you cant see?
d. Is your dad preoccupied with behaviors that he needs to repeat over and over?
ANS: A
Serotonin and its close chemical relatives, dopamine and norepinephrine, are the
neurotransmitters that are most widely involved in various forms of depression. Most
researchers agree that the immediate cause of parkinsonism is a deficiency of
dopamine and so a patient with Parkinsons disease should be monitored for
depression, The other mental health disorders (bipolar disorder, hallucinations, and
obsessive compulsive disorder) have not been connected to Parkinsons disease.
11. Which explanation for the prescription of donepezil (Aricept) would the nurse
provide for a patient in the early stage of Alzheimers disease?
a. It will increase the metabolism of excess GABA.
b. Excess dopamine will be prevented from attaching to receptor sites.
c. Serotonin deficiency will be managed through a prolonged reuptake period.
d. The acetylcholine deficiency will be managed by inhibiting cholinesterase.
ANS: D
Loading page 5...
symptoms of Alzheimers disease. The inhibiting action the drug has on cholinesterase
will slow down the breakdown of acetylcholine and so delay the onset of symptoms.
The other neurotransmitters (GABA, dopamine, and serotonin) are not currently
believed to play a role in Alzheimers disease.
12. There remains a stigma attached to psychiatric illnesses. The psychiatric nurse
makes the greatest impact on this sociological problem when:
a. Providing educational programming for patients and the public
b. Arranging for adequate and appropriate social support for the patient
c. Assisting the patient to achieve the maximum level of independent functioning
d.
Regularly praising the patient for seeking and complying with appropriate
treatment
ANS: A
Much of the stigma attached to psychiatric illness is due to a lack of understanding of
the biologic basis of these disorders. Therefore, effective patient, family, and public
teaching is an important function of the role of the psychiatric mental health nurse.
While the remaining options are appropriate, they are not directed towards eliminating
social stigma but rather empowering the patient.
13. The wife of a patient with paranoid schizophrenia tells the nurse, Ive learned that
my husband has several close relatives with the same disorder. Does this problem run
in families? The response based on recent discoveries in the field of genetics would
be:
a. Your children should be monitored closely for the disorder.
b. Research tends to support a familiar tendency to schizophrenia.
c. There is no concrete evidence; it is just as likely a coincidence.
d. Only bipolar disorder has been identified to have a genetic component.
ANS: B
Familial tendencies appear with several psychiatric disorders including schizophrenia.
To insinuate that the children are at such risk would not be supported by research.
14. A patient whose symptoms of mild depression have been managed with
antidepressants is concerned about the affect of accepting a promotion that will
require working the night shift. What will be the basis of the response the nurse gives
to address the patients concern?
a. The connection between a new job and possible depression does exist.
b. The medication can be adjusted to manage any increase in depression.
c. The interruption in normal wake-sleep patterns can influence mood disorders.
Loading page 6...
The change in sleep routine can be managed with a healthy sleep hygiene
routine.
ANS: C
Many psychiatric and medical disorders occur more frequently or are exacerbated
when sleep patterns and biologic rhythms are disrupted. While the remaining options
contain true information regarding the management of depression that is a result of
sleep disruption, they do not effectively address the patients concern.
15. The nurse is discouraged because the patient exhibiting negative symptoms of
schizophrenia has shown no improvement with the planned interventions to reduce the
symptoms. The mentors remark that helps place the problem in perspective is:
a. You arent responsible for the behavior of any other person.
b. Patients can be perverse and cling to symptoms despite our efforts.
c. Negative symptoms have been associated with genetic pathology.
d. It will take several trail and error attempts to get the right combination care.
ANS: C
A complex disorder, such as schizophrenia, most likely has multiple contributing
factors, including genetic predisposition, prenatal development, and the environment.
Nurse frustration can be alleviated by helping the nurse realize that negative
symptoms may be the result of actual brain dysfunction, rather than psychologically
determined behaviors; thus the remaining options are not appropriate since they do not
address the complexity of the problem.
MULTIPLE RESPONSE
1. What assessment data would reinforce the diagnosis of temporal lobe injury in
patient who experienced head trauma? Select all that apply.
a. Inability to balance a checkbook
b. Uncharacteristically aggressive
c. Affect fluctuates dramatically
d. Increased interest in sexual behaviors
e. Difficulty remembering the names of family members
ANS: C, D, E
The temporal lobe is involved with memory as well as increased sexual focus and
altered emotional responses. Personality and intellectual function is not centered in the
temporal lobe.
2. A patient has begun experiencing dysfunction of the hypothalamus. What nursing
interventions will the nurse include in the patients plan of care? Select all that apply.
a. Reinforcing clear physical boundaries
b. Assisting the patient with completing daily menus
Loading page 7...
d. Monitoring and recording temperature every 4 hours
e. Monitoring and recording blood pressure every 4 hours
ANS: B, C, D
The hypothalamus is responsible for regulation of sleep-rest patterns, body
temperature, and physical drives of hunger. Social appropriateness and blood pressure
is not controlled by the hypothalamus.
3. The nurse is preparing a patient for a positron emission tomography (PET) scan.
Which instructions will the nurse include? Select all that apply.
a.
There will likely be a 30 to 45 minute wait between the injection and the
beginning of the scan.
b.
A blindfold and earplugs may be used to help decrease reaction to the
environment during the scan.
c.
Make every attempt to lie still during the scan because movement will affect
the imaging produced.
d.
No food or fluids are to be ingested for at least 8 full hours before the scan and
none during the scan.
e.
Staying awake during the scan is important since the results are altered when
the patient is in any phase of the sleep state.
ANS: A, B, C, E
Appropriate patient preparation for a PET scan would include information regarding
the time interval between injection of the isotope and the actual scan, the fact that
steps will be taken to minimize the effects of sights and sounds during the scan, lying
still is critical to achieving a quality image, and that being asleep during the scan will
alter the results. It is not necessary to fast before or during the scan.
4. A patient with schizophrenia is described as having difficulty with executive
functions. What patient dysfunction can the nurse expect to assess behaviorally?
Select all that apply.
a. Invades the personal space of others frequently
b. Consistently fails to bring money when going to buy snacks
c. Cannot remember the names of staff who often provide care
d. Requires repeated reinforcement on how to make a sandwich
e. Frequently speaks of hurting himself or of hurting other patients
ANS: A, B, D
Executive functions include reasoning, planning, prioritizing, sequencing behavior,
insight, flexibility, judgment, focusing on tasks, responding to social cues, and
attending in appropriate ways to incoming stimuli. Memory is not considered an
Loading page 8...
appropriate for such a patient.
5. The unit physicians have ordered magnetic resonance imaging (MRI) tests for the
following patients. For which patients would the nurse decline to make test
arrangements without further discussion with the physician? Select all that apply.
a. A patient who is claustrophobic
b. A patient who is breastfeeding
c. A patient who has an allergy to iodine
d. A patient who had a total knee replacement
e. A patient who is taking a neuroleptic medication
ANS: A, D
Patients with claustrophobia are often unable to complete this type of study, because
the MRI machine is enclosed, and patients are required to remain motionless. Metal
implants are contraindications for MRIs since metal affects the scan. Breastfeeding,
iodine sensitivity, and neuroleptic medication therapy are not contraindications for an
MRI.

1. A newly admitted patient has the diagnosis of catatonic schizophrenia. Which
behavior observed in the patient supports that diagnosis?
a. Uses a rhyming form of speech
b. Refuses to eat any unwrapped foods
c. Laughs when watching a sad movie
d. Maintains an immobilized state for hours
ANS: D
Catatonic schizophrenia is characterized by extremes of psychomotor activity ranging
from frenzied behavior to immobilization and may include echopraxia and posturing.
Paranoid thinking is characteristic of paranoid schizophrenia. Inappropriate affect and
clanging are seen in disorganized schizophrenia.
2. What would be an appropriate short-term outcome for a patient diagnosed with
residual schizophrenia who exhibits ambivalence?
a. Decide their own daily schedule.
b. Decide which unit groups they will attend.
c. Choose which clinic staff member to work with.
d. Choose between two outfits to wear each morning.
ANS: D
An early step would be to make choices about nonthreatening matters when presented
with limited alternatives. The remaining options represent decisions that are too
complicated for the patient to make initially.
3. What is the priority nursing diagnosis for a catatonic patient?
a. Ineffective coping
b. Impaired physical mobility
c. Impaired social interaction
d. Risk for deficient fluid volume
ANS: D
The highest priority for the patient is maintenance of basic physiologic needs, such as
hydration. Mobility is of lesser physiological importance than fluid volume. The
remaining options do not have priority over a physiological need.
4. Which nursing diagnosis is appropriate for a patient who insists being called Your
Highness and demonstrates loosely associated thoughts?
a. Risk for violence
b. Defensive coping
c. Impaired memory
Loading page 21...
ANS: D
Delusions and loose associations suggest disturbed thought processes. The other
options are not supported by data in the scenario.
5. Which initial short-term outcome would be appropriate for a patient who was
admitted expressing delusional thoughts?
a. Accept that delusion is illogical.
b. Distinguish external boundaries.
c. Explain the basis for the delusions.
d. Engage in reality-oriented conversation.
ANS: D
Delusions are not reality oriented; thus an appropriate outcome would be that patient
will engage in reality-oriented conversation rather than discussing delusional beliefs.
Delusions are fixed, false beliefs. Patients rarely accept anyone using logic to dispute
them. Data are not present to suggest boundary disturbance. Explaining the delusion is
not progress; it suggests the patient still holds to the belief.
6. Which of the following interventions should the nurse plan to use to reduce patient
focus on delusional thinking?
a. Confronting the delusion
b. Refuting the delusion with logic
c. Exploring reasons the patient has the delusion
d. Focusing on feelings suggested by the delusion
ANS: D
Focusing on feelings suggested by the delusion will help meet patient needs and help
the patient stay based in reality. This technique fosters rapport and trust while
discouraging the belief without challenging or refuting it.
7. Which assessment observation supports a patients diagnosis of disorganized
schizophrenia?
a. Reports suicidal ideations
b. Last relapse was 6 years ago
c. Consistent inappropriate laughing
d. Believes that the government is out to get me

8. A patient tried to gouge out his eye in response to auditory hallucinations
commanding, If thine eye offends thee, pluck it out. The nurse would analyze this
behavior as indicating:
a. Derealization
b. Inappropriate affect
c. Impaired impulse control
d. Inability to manage anger
ANS: C
Command hallucinations may be so intense that the patient cannot control the impulse
to do what the hallucination tells him to do; thus the patient has impaired impulse
control. This is not an anger management problem. Derealization is a feeling that the
environment is distorted or unreal and not suggested in the scenario. No evidence of
inappropriate affect is given.
9. An appropriate intervention for a patient with an identified nursing diagnosis of
situational low self-esteem would be:
a. Providing large muscle activities to relieve stress
b. Attempting to determine triggers to hallucinations
c. Engaging patient in activities designed to permit success
d. Encouraging verbalization of feelings in a safe environment
ANS: C
All are useful interventions for a patient with schizophrenia; however, engaging the
patient in specifically designed activities is the only option that addresses improving
self-esteem.
10. A 19-year-old patient is admitted for the second time in 9 months and is acutely
psychotic with a diagnosis of undifferentiated schizophrenia. The patient sits alone
rubbing her arms and smiling. She tells the nurse her thoughts cause earthquakes and
that the world is burning. The nurse assesses the primary deficit associated with the
patients condition as:
a. Social isolation
b. Disturbed thinking
c. Altered mood states
d. Poor impulse control
ANS: B
Loading page 23...
disturbed thought processes. Social isolation is not the primary patient problem. No
data exist to support the other options.
11. A patient has been admitted with disorganized type schizophrenia. The nurse
observes blunted affect and social isolation. He occasionally curses or calls another
patient a jerk without provocation. The nurse asks the patient how he is feeling, and
he responds, Everybody picks on me. They frobitz me. The patients communication
exhibits:
a. A neologism
b. Loose associations
c. Delusional thinking
d. Circumstantial speech
ANS: A
A newly coined word having meaning only for the patient is called a neologism
(meaning, new word). It is associated with autistic thinking. The patients speech does
not show associative looseness or circumstantiality. The use of a neologism is not
delusional in and of itself, but it suggests delusional thinking may be present.
12. A patient has been admitted with disorganized type schizophrenia. The nurse asks
the patient how he is feeling, and he responds, Everybody picks on me. They frobitz
me. The best response for the nurse to make would be:
a. Thats really too bad that you are being treated that way.
b. Who do you mean when you say everybody?
c. What difference does frobitzing make?
d. Why do they frobitz?
ANS: B
This response will help clarify the patients thinking and change the focus from global
to specific. In this situation, sympathizing with the patient is a nonproductive
response. The remaining options appear to accept the neologism thus supporting the
patients delusional thinking.
13. Which patient behavior would support the diagnosis of residual schizophrenia
with negative symptoms?
a. Communicating using only rhyming phases
b. Claims that worms are crawling in my brain
c. Maintaining both arms suspended awkwardly overhead
d. Shows no emotion when telling the story of a sisters recent death
ANS: D

classified as positive symptoms.
14. By discharge, which outcome is appropriate for a patient who hears voices telling
him he is evil?
a. Respond verbally to the voices.
b. Verbalize the reason the voices say he is evil.
c. Identify events that increase anxiety and promote hallucinations.
d. Integrate the voices into his personality structure in a positive manner.
ANS: C
An appropriate outcome for a patient with hallucinations is recognition of events that
precede the onset of hallucinations. Trigger events or situations usually cause
increased feelings of anxiety. The remaining options are neither desirable nor
appropriate.
15. Which response by the nurse would best assist a patient in de-escalating
aggressive behavior?
a. Tell me whats going on.
b. Why are you getting so upset?
c. If you throw something, you will be restrained.
d. Its time for group therapy. You can talk there.
ANS: A
Using how, what, and when to gather information is a nonthreatening approach. It will
promote patient verbalization and explanation of events without causing the patient to
become defensive. Mentioning restraints sounds threatening even though it may be
meant to remind the patient of limits.Why questions are demanding and threatening to
patients. Sending the patient into group therapy sidesteps the problem.
16. A 34-year-old male admitted with catatonic schizophrenia has been mute and
motionless for several days while at home prior to admission. He still appears
stuporous in the hospital. Which nursing intervention would be an initial priority?
a. Orienting the patient to the unit
b. Reinforcing reality with the patient
c. Establishing a nonthreatening relationship
d. Assessing the patient for physical problems
ANS: D
Patients who are mute and motionless and inattentive to environmental stimuli are at
risk for a number of physical problems. Further, they are unable to communicate
existing problems. The nurse must make thorough and astute assessments before
creating plans to meet the patients needs. A patient who is stuporous may not be able

therapeutic nurse-patient relationship is an important intervention, it does not have
priority according to Maslows hierarchy. Because the patient is mute, one can only
suspect lack of reality orientation. While an appropriate intervention, it is not the
priority according to Maslows hierarchy.
17. Which response is appropriate when a patients mother expresses guilt over
causing my child to be schizophrenic?
a. I can see how you would be upset over this turn of events.
b. New findings suggest this disorder is biological in nature.
c. Dont be so hard on yourself; your daughter needs you to be strong.
d. Its difficult to see what produces stress for the child at the time its occurring.
ANS: B
Many individuals in the mental health field attribute the development of schizophrenia
to multiple causes centering on biological theories. The remaining options do little to
provide the mother with new information.
18. Which response demonstrates both empathy and understanding of the relationship
genetics has to the development of schizophrenia in twins?
a.
In fraternal twins, the chance of the other twin developing the disorder is quite
small.
b.
Studies show that 50% of twins develop schizophrenia when it is present in the
other twin.
c.
No one can say what will happen, so we will hope for the best for you and
both of your sons.
d.
You poor woman! I wish I could tell you that your other son he will be free of
the disorder.
ANS: A
Current research supports the correct option, whereas the remaining options are not
factual and show expressed sympathy rather than empathy.
19. The wife of a patient diagnosed with paranoid schizophrenia asks, Ive been told
that my husbands illness is probably related to imbalanced brain chemicals. Can you
be more specific? The response based on the dopamine hypothesis is:
a.
Breakdown of dopamine produces LSD, which in large amounts produces
psychosis.
b.
An increase in the brain chemical dopamine explains the presence of delusions
and hallucinations.
c.
Decreased amounts of the brain chemical dopamine explain the presence of
delusions and hallucinations.
Loading page 26...
An increase in the brain chemical dopamine explains the presence of lack of
motivation and disordered affect.
ANS: B
The statement is correctly based on the dopamine hypotheses while the remaining
options are neither known to be true nor based on that theory
20. What is the basis for the reduction in disturbed thought processes when a patient is
administered haloperidol (Haldol)?
a. Reduction in the number of brain cells that crave dopamine
b. Dopamine receptors are blocked, making dopamine less available
c. Dopamine receptors are enhanced, making more dopamine available
d. Medication causes an increased cellular production of dopamine
ANS: B
Excess dopamine is responsible for symptoms of psychosis such as delusions and
hallucinations. Blocking dopamine receptors will result in reduction of primary
symptoms. The other options do not reflect the action of typical antipsychotic
medications.
21. During a treatment team meeting, the point is made that a patient with
schizophrenia has recovered from the acute psychosis but continues to demonstrate
apathy, avolition, and blunted affect. The nurse who relates these symptoms to
serotonin (5HT2) excess will suggest that the patient receive:
a. Haloperidol (Haldol)
b. Chlorpromazine (Thorazine)
c. Olanzapine (Zyprexa)
d. Phenelzine (Nardil)
ANS: C
Olanzapine is an atypical antipsychotic. Atypical antipsychotic medications are more
effective than typical antipsychotics in blocking serotonin receptors and reducing the
negative symptoms of schizophrenia. Haloperidol (Haldol) and chlorpromazine
(Thorazine) are typical antipsychotic medications while phenelzine (Nardil) is an
MAOI antidepressant.
22. What response would be anticipated when a patient who received chlorpromazine
(Thorazine) for 15 years to treat schizophrenia is switched to Seroquel (quetiapine)?
a. Development of pseudoparkinsonism
b. Development of dystonic reactions
c. Improvement in tardive dyskinesia
d. Worsening of anticholinergic symptoms
ANS: C
Loading page 27...
dyskinesia as well as improve both positive and negative symptoms of schizophrenia.
Pseudoparkinsonism and dystonic reactions are associated with typical antipsychotic
medication. Anticholinergic symptoms are not intense with the use of atypical
antipsychotic medication.
23. A patient admitted with the diagnosis of schizophreniform disorder R/O organic
pathology. Based on this information, the nurse can expect that the patient will:
a. Be scheduled for a magnetic resonance imaging (MRI) test
b. See a mental health specialist for extensive psychological testing
c. Have an immunologic assay performed within 2 days of the admission
d.
Participate in a dexamethasone suppression test (DST) administered by the
staff
ANS: A
The MRI will reveal structural changes in the brain that might be responsible for
symptoms of psychosis (e.g., abscess, tumor). Psychologic testing may be performed
but will be less definitive in ruling out organic pathology. Immunologic studies are
not indicated. The DST is related to depression.
24. In planning aftercare for a patient with schizophrenia and whose insurance
benefits have been exhausted, the nurse who is concerned about overcoming negative
symptoms will make provisions for the patient to have stimulation, structure,
socialization, and support. Which option would best incorporate these factors?
a. Day hospitalization
b. Attending a psychosocial club
c. Living with his elderly mother
d. Spending free time in the mall
ANS: B
A psychosocial club is organized to provide the 4 Ss and is not costly to patients. Day
hospitalization would not be possible because of the lack of insurance benefits. Living
with his mother might fall short of stimulation and support. Spending time in the mall
lacks structure, socialization, and support.
25. A patient with catatonic schizophrenia has been standing with his left arm
upraised and his right foot off the floor for the majority of the last 20 hours, eating
only when allowed to eat standing up. Which nursing intervention has priority for this
patient?
a. Providing high-calorie drinks hourly
b. Assessing for lower extremity edema bid
c. Taking the patient to activities therapy once daily
Loading page 28...
ANS: B
Patients who maintain one position for long periods of time should be assessed for
dependent edema. In this case, the nurse would look for edema of the lower
extremities and would be concerned about the pressure exerted by standing on one
foot for long periods of time. Such encouragement would probably be met with
resistance by the patient. High-calorie drinks would be necessary if the patient failed
to eat at meals. The patient probably would not be able to cognitively process what is
required to participate in activities.
26. Which nursing action best addresses the needs of a paranoid patient who believes
the food is poisoned?
a. Explaining that others eat the food and are not harmed
b. Allowing the patient to select food from vending machines
c. Encouraging the patient to discuss why someone would poison the food
d. Taking steps to prevent the patient from verbalizing the delusional thoughts
ANS: B
Patients who think hospital food is being poisoned will sometimes eat wrapped foods
that have not been opened, and occasionally, they may eat food brought from the
outside by a trusted person. Delusions are fixed, false beliefs that cannot be refuted by
logic. The patient will probably state that the others have been given the antidote to
the poison. Encouraging discussion about the delusion is not therapeutic. Although it
is wise to minimize the amount of discussion about delusions, refusing to allow the
patient to speak about the delusions will not foster a therapeutic alliance.
27. Prior to discharge, the nurse plans to teach the patient and family about relapse.
Which items will the nurse include in the teaching?
a. Recognizing warning signs of relapse
b. Using street drugs judiciously and only in small amounts
c. Lowering medication dosage to manage emerging side effects
d. Notifying the nurse of warning signs present for more than one month
ANS: A
The patient and family must be aware of signs of impending relapse. These signs are
usually similar to those that the patient experienced prior to hospitalization and will be
patient-specific. The nurse should be notified ASAP, rather than waiting two weeks.
Patients should never adjust medication dosage. Street drug use often precipitates
relapse since many street drugs are dopaminergic.
28. Because of the cognitive disturbances associated with schizophrenia, which
technique will be useful as the nurse teaches a patient about self-management?
a. Use only verbal instruction.
Loading page 29...
c. Offer opportunities for making numerous choices.
d. Plan the teaching for a time when the patient has been recently medicated.
ANS: B
Patients with cognitive disturbances should be taught small blocks of information at a
time and given frequent reinforcement. Both verbal and visual materials should be
used since processing of verbal stimuli may be more impaired. Teaching should be
scheduled when the patient is most alert. A large number of choices may be confusing
for the person, but a few simple choices may be included.
29. The wife of a patient newly diagnosed with paranoid schizophrenia is concerned
that her husband will be this sick for the rest of his life. What information can the
nurse provide to the wife?
a. This disorder generally responds well with treatment and follow-up.
b. All types of schizophrenia by their nature are chronic relapsing disorders.
c. Outcomes are related to the patients pre-hospital symptoms of disorganization.
d. The typical outcome for this diagnosis is that total remission is not achievable.
ANS: A
The prognosis for paranoid schizophrenia is good with appropriate treatment and
effective follow-up. The remaining options are not correct when considering this type
of schizophrenia
30. A patient is exhibiting auditory hallucinations in addition to being forgetful and
easily confused. Which diagnosis does the nurse base this patients interventions on?
a. Social isolation
b. Deficient knowledge
c. Situational low self-esteem
d. Impaired cognitive functioning
ANS: D
Schizophrenia may alter cognitive functioning, including memory, retention,
attention, and the processing of incoming information. Altered cognition accounts for
many of the symptoms mentioned in the scenario. Knowing that cognition is altered,
the nurse can adjust plans to take the deficits into account. The patient is not
exhibiting symptoms that would warrant any of the other options.
31. A patient experiences intrusive, insulting auditory hallucinations. Which
independent behavioral technique can the nurse teach the patient to employ when the
voices are troublesome?
a. Introduce a distraction like reading.
b. Use positive talk to offset the insults.
Loading page 30...
d. Increase the daily dose of an antipsychotic medication.
ANS: C
This action provides an alternative to listening to the voices and gives the patient a
sense of control. The patient should not adjust medication independently. Reading
will not be particularly effective, because the voices are uncontested in a quiet
atmosphere. Positive talk is generally used to positively affect self-esteem.
32. A patient with schizophrenia tells the nurse as they sit in the day room, I hear
voices telling me bad things. The most therapeutic response the nurse can make is:
a. Tell me what the voices are saying.
b. I believe you hear voices, but I dont hear them myself.
c. The voices are not real. Theyre a product of your imagination.
d. Do you think the voices would go away if we went into your room to talk?
ANS: B
By voicing his or her own reality related to the voices, the nurse does not deny the
patients experiences but helps the patient distinguish actual voices from those
resulting from internal stimulation. Discussing what the voices are saying serves only
to validate the reality of the voices. Challenging the voices will cause the patient to
defend his perceptions and thereby reinforce the importance of the hallucination.
Asking to move validates the reality of the voices and is not a helpful action since the
voices go where the patient goes.
33. A patient tells the nurse, When Im in the day room, I hear people whispering
about me, and that makes me want to punch them. What direction will the nurse
provide the staff regarding interacting with this patient?
a. To minimize the need to whisper, utilize nonverbal techniques when possible.
b.
Stay physically close to this patient and use touch as a tool to interact with
him.
c.
Treat this patient matter-of-factly. Be direct; dont talk about him or others in
his presence.
d.
Interact with this patient only when necessary. The fewer interactions, the
fewer misinterpretations there will be.
ANS: C
This approach is important when providing care for a patient who is misinterpreting
reality and is suspicious of the motives of others. Ostracizing the patient is non-
therapeutic. Patients often misinterpret touch as threatening. This might promote loss
of control. Using nonverbal communication techniques would be nontherapeutic as it
would increase patient anxiety and promote loss of control.
