bipolar disorders Flashcards
A person was online continuously for over 24 hours, posting rhymes on official government Web sites and inviting politicians to join social networks. The person has not slept or eaten for 3 days. What features of mania are evident?
a.Increased muscle tension and anxiety
b.Vegetative signs and poor grooming
c.Poor judgement and hyperactivity
d.Cognitive deficits and paranoia
ANS: C
Hyperactivity (activity without sleep) and poor judgement (posting rhymes on government Web sites) are characteristic of manic episodes. The distracters do not specifically apply to mania.
- A patient diagnosed with bipolar disorder is dressed in a red leotard and bright scarves. The patient twirls and shadow boxes. The patient says gaily, “Do you like my scarves? Here; they are my gift to you.” How should the nurse document the patient’s mood?
a.Euphoric
b.Irritable
c.Suspicious
d.Confident
ANS: A
The patient has demonstrated clang associations and pleasant, happy behaviour. Excessive happiness indicates euphoria. Irritability and confidence are not the best terms for the patient’s mood. Suspiciousness is not evident.
A person was directing traffic on a busy street, rapidly shouting, “To work, you jerk, for perks” and making obscene gestures at cars. The person has not slept or eaten for 3 days. Which assessment findings will have priority concern for this patient’s plan of care?
a.Insulting, aggressive behaviour
b.Pressured speech and grandiosity
c.Hyperactivity; not eating and sleeping
d.Poor concentration and decision making
ANS: C
Hyperactivity, poor nutrition, poor hydration, and not sleeping take priority in terms of the needs listed above because they threaten the physical integrity of the patient. The other behaviours are less threatening to the patient’s life
A patient diagnosed with acute mania has distributed pamphlets about a new business venture on a street corner for 2 days. Which nursing diagnosis has priority?
a.Risk for injury
b.Ineffective coping
c.Impaired social interaction
d.Ineffective therapeutic regimen management
ANS: A
Although each of the nursing diagnoses listed is appropriate for a patient having a manic episode, the priority lies with the patient’s physiological safety. Hyperactivity and poor judgement put the patient at risk for injury.
A patient diagnosed with bipolar disorder becomes hyperactive after discontinuing lithium. The patient threatens to hit another patient. Which comment by the nurse is appropriate?
a.“Stop that! No one did anything to provoke an attack by you.”
b.“If you do that one more time, you will be secluded immediately.”
c.“Do not hit anyone. If you are unable to control yourself, we will help you.”
d.“You know we will not let you hit anyone. Why do you continue this behaviour?”
ANS: C
When the patient is unable to control his or her behaviour and violates or threatens to violate the rights of others, limits must be set in an effort to de-escalate the situation. Limits should be set in simple, concrete terms. The incorrect responses do not offer appropriate assistance to the patient, threaten the patient with seclusion as punishment, and ask a rhetorical question.
This nursing diagnosis applies to a patient with acute mania: Imbalanced nutrition: less than body requirements related to insufficient caloric intake and hyperactivity as evidenced by 5-pound weight loss in 4 days. Select an appropriate outcome.
a.The patient will ask staff for assistance with feeding within 4 days.
b.The patient will drink six servings of a high-calorie, high-protein drink each day.
c.The patient will consistently sit with others for at least 30 minutes at meal time within 1 week.
d.The patient will consistently wear appropriate attire for age and sex within 1 week while on the psychiatric unit.
ANS: B
High-calorie, high-protein food supplements will provide the additional calories needed to offset the patient’s extreme hyperactivity. Sitting with others or asking for assistance does not mean the patient eats or drinks. The other indicator is unrelated to the nursing diagnosis.
A patient demonstrating characteristics of acute mania relapsed after discontinuing lithium. New orders are written to resume lithium twice daily and begin olanzapine (Zyprexa). What is the rationale for the addition of olanzapine to the medication regimen?
a.It minimizes the side effects of lithium.
b.It brings hyperactivity under rapid control.
c.It enhances the antimanic actions of lithium.
d.It is used for long-term control of hyperactivity.
ANS: B
Manic symptoms are controlled by lithium only after a therapeutic serum level is attained. Because this takes several days to accomplish, a drug with rapid onset is necessary to reduce the hyperactivity initially. Antipsychotic drugs neither enhance lithium’s antimanic activity nor minimize the side effects. Lithium is used for long-term control.
A patient diagnosed with bipolar disorder has rapidly changing mood cycles. The health care provider prescribes an anticonvulsant medication. To prepare teaching materials, which drug should the nurse anticipate will be prescribed?
a.Phenytoin (Dilantin)
b.Gabapentin (Neurontin)
c.Risperidone (Risperdal)
d.Carbamazepine (Tegretol)
ANS: D
Some patients with bipolar disorder, especially those who have only short periods between episodes, have a favourable response to the anticonvulsants carbamazepine and valproate. Carbamazepine seems to work better in patients with rapid cycling and in severely paranoid, angry manic patients. Phenytoin is also an anticonvulsant but not used for mood stabilization. Risperidone is not an anticonvulsant. Gabapentin is an anticonvulsant that is used primarily for maintenance treatment of bipolar disorder.
The exact cause of bipolar disorder has not been determined; however, for most patients, which of the following is true?
a.Several factors, including genetics, are implicated.
b.Brain structures were altered by stress early in life.
c.Excess sensitivity in dopamine receptors may trigger episodes.
d.Inadequate norepinephrine reuptake disturbs circadian rhythms.
ANS: A
The best explanation at this time is that bipolar disorder is most likely caused by interplay of complex independent variables. Various theories implicate genetics, endocrine imbalance, environmental stressors, and neurotransmitter imbalances.
The spouse of a patient diagnosed with bipolar disorder asks what evidence supports the possibility of genetic transmission of bipolar disorders. Which response should the nurse provide?
a.“A high proportion of patients with bipolar disorders are found among creative writers.”
b.“A higher rate of relatives with bipolar disorder is found among patients with bipolar disorder.”
c.“Patients with bipolar disorder have higher rates of relatives who respond in an exaggerated way to daily stress.”
d.“More individuals with bipolar disorder come from high socioeconomic and educational backgrounds.”
ANS: B
Evidence of genetic transmission is supported when twins or relatives of patients with a particular disorder also show an incidence of the disorder that is higher than the incidence in the general public. The incorrect options do not support the theory of genetic transmission and other factors involved in the etiology of bipolar disorder.
A patient diagnosed with bipolar disorder commands other patients, “Get me a book. Take this stuff out of here,” and other similar demands. The nurse wants to interrupt this behaviour without entering into a power struggle. Which initial approach should the nurse select?
a.Distraction: “Let’s go to the dining room for a snack.”
b.Humor: “How much are you paying servants these days?”
c.Limit setting: “You must stop ordering other patients around.”
d.Honest feedback: “Your controlling behaviour is annoying others.”
ANS: A
The distractibility characteristic of manic episodes can assist the nurse to direct the patient toward more appropriate, constructive activities without entering into power struggles. Humor usually backfires by either encouraging the patient or inciting anger. Limit setting and honest feedback may seem heavy-handed and may incite anger.
The nurse receives a laboratory report indicating a patient’s serum lithium level is 1 mEq/L. The patient’s last dose of lithium was 8 hours ago. How should the nurse interpret this result?
a.This result is within therapeutic limits.
b.This result is below therapeutic limits.
c.This result is above therapeutic limits.
d.This result is invalid because of the time lapse since the last dose.
ANS: A
Normal range for a blood sample taken 8 to 12 hours after the last dose of lithium is 0.4 to 1 mEq/L.
Consider these three anticonvulsant medications used in mood stabilization: divalproex sodium (Epival), carbamazepine (Tegretol), and gabapentin (Neurontin). Which of the following medications also belongs to this classification?
a.Clonazepam (Rivotril)
b.Risperidone (Risperdal)
c.Lamotrigine (Lamictal)
d.Aripiprazole (Abilify)
ANS: C
The three drugs in the question are all anticonvulsants. Lamotrigine is also an anticonvulsant. Clonazepam is an anxiolytic; aripiprazole and risperidone are antipsychotic drugs.
- When a hyperactive patient diagnosed with acute mania is hospitalized, what is the initial nursing intervention?
a.Allow the patient to act out feelings.
b.Set limits on patient behaviour as necessary.
c.Provide verbal instructions to the patient to remain calm.
d.Restrain the patient to reduce hyperactivity and aggression.
ANS: B
This intervention provides support through the nurse’s presence and provides structure as necessary while the patient’s control is tenuous. Acting out may lead to loss of behavioural control. The patient will probably be unable to focus on instructions and comply. Restraint is used only after other interventions have proved ineffective.
At a unit meeting, the staff discusses decor for a special room for patients with acute mania. Which suggestion is appropriate?
a.An extra-large window with a view of the street
b.Neutral walls with pale, simple accessories
c.Brightly coloured walls and print drapes
d.Deep colours for walls and upholstery
ANS: B
The environment for a manic patient should be as simple and nonstimulating as possible. Manic patients are highly sensitive to environmental distractions and stimulation.
