NURS 340: UNIT 10 - SCHIZOPHRENIA

What symptom is present when a patient firmly believes the television is sending secret messages specifically to them?

A delusion — a fixed false belief; a positive symptom.

A patient hears voices when nobody is present. What symptom is this?

An auditory hallucination — perceiving sound without an external stimulus; a positive symptom.

A patient stops initiating daily activities, such as showering or dressing. Which symptom may be present?

Avolition — reduced motivation and initiation; a negative symptom.

A patient no longer enjoys previously favorite activities. Which symptom is present?

Anhedonia — reduced ability to experience pleasure; a negative symptom.

A patient gives very brief answers and rarely speaks spontaneously. Which symptom may be present?

Alogia — reduced speech output; a negative symptom.

A patient speaks in a confusing sequence of unrelated ideas. Which symptom is present?

Disorganized speech — impaired organization of thoughts; a positive symptom.

A patient struggles with memory, attention, and planning. Which symptom dimension is affected?

The cognitive dimension, involving memory, attention, problem-solving, and executive function.

A patient says, “Nothing will ever get better. Everyone would be better off without me.” What should the nurse assess first?

Suicide risk and immediate safety. Hopelessness and suicidal ideation are affective symptoms.

A patient shows little facial expression or emotional variation. Which symptom may be present?

Blunted or flat affect — reduced or absent observable emotional expression; a negative symptom.

A patient has very little energy and remains inactive most of the day. Which symptom may be present?

Anergia — reduced energy; also assess for depression, medication effects, and medical causes.

A patient remains in a fixed posture and responds minimally to instructions. Which symptom may be present?

Catatonia — a disturbance of movement or responsiveness requiring clinical assessment.

Why should nurses assess all four psychotic symptom dimensions?

Symptoms can coexist and affect safety, functioning, cognition, motivation, and emotional well-being.

A patient experiences hallucinations and delusions for eight months with significant functional decline. Which disorder is most consistent?

Schizophrenia — disturbance lasting at least six months, including at least one month of active symptoms, with significant functional decline.

A patient has schizophrenia-like symptoms for three months and later returns to baseline. Which disorder is most consistent?

Schizophreniform disorder — symptoms last 1–6 months; recovery often occurs.

A patient experiences psychosis alongside major depressive or manic episodes. Which disorder should be considered?

Schizoaffective disorder. Assess the timing of mood episodes and psychosis, including whether psychosis occurs without a major mood episode.

A patient believes a neighbor is poisoning their food for two months but otherwise functions well. Which disorder is most consistent?

Delusional disorder — delusions lasting at least one month without markedly impaired overall functioning.

A patient develops sudden psychosis after trauma and returns to baseline within two weeks. Which disorder is most consistent?

Brief psychotic disorder — psychosis lasting more than one day but less than one month, followed by return to baseline.

A patient develops hallucinations after starting a medication, and symptoms resolve after it is discontinued. Which disorder should be investigated?

Substance- or medication-induced psychotic disorder. The timing of exposure and symptoms is an important clue.

A patient has longstanding eccentric behavior, unusual beliefs, and difficulty forming close relationships, with less impairment than schizophrenia. Which condition is most consistent?

Schizotypal personality disorder — a longstanding personality-level pattern.

One patient has psychotic symptoms for four months; another has symptoms for nine months with significant functional decline. How do their likely diagnoses differ?

The first suggests schizophreniform disorder; the second suggests schizophrenia, assuming other diagnostic criteria are met.

A patient develops psychosis during substance withdrawal. What supports a substance-induced cause?

A temporal and clinical relationship between withdrawal and psychosis, after considering other causes.

A patient has delusions for six weeks but continues working and managing daily activities. Why is schizophrenia not established?

Delusions alone do not establish schizophrenia. Assess duration, other symptoms, functional decline, and alternative causes.

A patient believes staff implanted a device in their head to control their thoughts. Which symptom is present?

A. Auditory hallucination
B. Delusion
C. Anhedonia
D. Alogia

B. Delusion

C. Assess suicide risk and initiate safety measures.

A patient develops psychosis after starting a medication. Which cause should be investigated?

A. Medication-induced psychotic disorder
B. Schizotypal personality disorder
C. Schizophrenia based on hallucinations alone
D. Delusional disorder based on duration alone

A. Medication-induced psychotic disorder

A patient has longstanding eccentric behavior and unusual beliefs, with less impairment than schizophrenia. Which condition fits best?

A. Brief psychotic disorder
B. Schizotypal personality disorder
C. Schizophreniform disorder
D. Medication-induced psychosis

A. Schizophrenia
B. Schizophreniform disorder
C. Brief psychotic disorder
D. Schizotypal personality disorder

C. Brief psychotic disorder

What is the difference between positive and negative symptoms?

• Positive: Something added, such as hallucinations or delusions.

• Negative: Something reduced or absent, such as motivation, speech, pleasure, or emotional expression.

How do schizophrenia and schizophreniform disorder differ?

• Schizophrenia: At least six months, with significant functional decline.

• Schizophreniform: One to six months; functioning may remain intact.

What distinguishes brief psychotic disorder from schizophrenia?

Brief psychotic disorder lasts less than one month, followed by return to baseline. Schizophrenia involves at least six months of disturbance and significant functional decline.

Why should nurses assess substance and medication causes of psychosis?

Psychosis may result from substance exposure, withdrawal, or medication effects, which can change treatment and prognosis.

What should nurses assess when a patient has symptoms across multiple dimensions?

Safety, hallucinations and delusions, motivation, cognition, emotional state, functioning, and possible underlying causes.

What is the leading theory explaining the pathophysiology of schizophrenia?

Dopamine overactivity. First-generation antipsychotics block D2 receptors, reducing positive symptoms such as hallucinations and delusions.

Why do researchers suspect glutamate plays a role in schizophrenia?

PCP can produce schizophrenia-like symptoms, suggesting glutamate dysfunction may contribute.

Does schizophrenia result from genetics alone?

No. It involves genetic vulnerability interacting with neurobiological and environmental factors, such as developmental complications and stress.

What does it mean that genetics account for about 80% of schizophrenia risk?

Genetics contribute substantially to vulnerability, but genetic risk does not guarantee that someone will develop schizophrenia.

A teenager gradually withdraws from friends, neglects hygiene, and struggles in school before developing hallucinations. What phase may this represent?

The prodromal phase, when early changes in functioning and negative symptoms may appear before prominent psychosis.

At what ages does schizophrenia typically begin in males and females?

• Males: 15–25 years.

• Females: 25–35 years.

These are typical ranges, not strict diagnostic limits.

What is the most common type of hallucination in schizophrenia?

Auditory hallucinations, such as hearing voices.

What is the most common type of delusion in schizophrenia?

Persecutory delusions, involving beliefs that someone intends to harm, threaten, or target the person.

A patient creates new, invented words that others cannot understand. What speech disturbance is this?

Neologisms — invented words with personal meanings.

A patient's speech jumps between unrelated ideas with weak connections. What is this called?

Loose associations — disorganized connections between thoughts.

A patient speaks in a jumble of words that lacks meaningful organization. What is this called?

Word salad — severely disorganized speech that is difficult or impossible to understand.

A patient chooses words because they rhyme rather than because they make sense. What is this called?

Clang associations — speech guided by sound or rhyme rather than meaning.

A patient repeatedly echoes the nurse's words. What symptom is present?

Echolalia — repeating another person's words.

Which negative symptom involves decreased desire for social interaction and is identified as a major warning sign of relapse?

Asociality — reduced desire for social interaction.

• Increasing social withdrawal can signal relapse.

A patient does not recognize that they have schizophrenia and believes treatment is unnecessary. What symptom may explain this?

Anosognosia — impaired awareness of having an illness, which can interfere with treatment adherence.

A patient interprets statements literally and struggles to understand metaphors. What cognitive symptom is present?

Concrete thinking — difficulty understanding abstract concepts or figurative language.

A patient with schizophrenia stops showering and changing clothes. Why is this clinically important?

Neglected hygiene can be an early sign of deterioration or relapse.

• Assess sleep, social withdrawal, concentration, and other changes.

What are the key DSM-5-TR duration requirements for schizophrenia?

At least two characteristic symptoms, including at least one delusion, hallucination, or disorganized speech; at least one month of active symptoms and six months of continuous signs overall.

Why can't a blood test confirm schizophrenia?

There is no definitive laboratory test. Investigations help exclude substance-related, neurological, and other medical causes.

Why should baseline weight, BMI, glucose, lipids, and blood pressure be assessed before antipsychotic treatment?

To identify baseline health risks and monitor for metabolic adverse effects, including weight gain, hyperglycemia, and dyslipidemia.

Why might an ECG be obtained before antipsychotic treatment?

To assess cardiac electrical activity, including QT prolongation risk, when clinically indicated by the medication and patient factors.

What does the AIMS assessment monitor in a patient taking antipsychotics?

Abnormal involuntary movements, particularly tardive dyskinesia.

What baseline blood tests are especially important before starting clozapine?

White blood cell count (WBC) and absolute neutrophil count (ANC) to assess for neutropenia risk.

When is clozapine generally considered for schizophrenia?

For treatment-resistant schizophrenia, typically after inadequate response to at least two appropriate antipsychotic trials.

What is the primary goal during the acute phase of schizophrenia treatment?

Stabilize symptoms and maintain safety, including hospitalization when necessary to manage serious danger to self or others.

What are the main goals of stabilization and maintenance treatment?

Prevent relapse, support medication adherence, maintain functioning, and strengthen community and social support.

A patient reports hearing voices. What should the nurse ask first?

“What are you hearing?” This assesses the experience without reinforcing or dismissing it.

A patient says a voice is ordering them to jump from a window. What should the nurse do?

Assess command hallucinations and immediate safety risk, including the command's content, intent to obey, and ability to resist. Initiate appropriate safety measures.

Why should a nurse avoid arguing with a patient about hallucinations?

Arguing can damage trust. Instead, acknowledge the patient's distress without confirming the hallucination and state your own perception calmly.

A patient is distracted by voices during an activity. What can the nurse suggest?

Use competing stimuli, such as music, reading, or humming, and gently encourage reality testing.

A patient believes staff are plotting to harm them. How should the nurse respond?

Acknowledge the fear without agreeing with the delusion, such as: “That sounds frightening. I don't see evidence that staff are trying to harm you.”

Why should nurses avoid directly debating delusions?

Debating often increases distress and mistrust. Validate the emotion, avoid reinforcing the false belief, and redirect toward reality-based topics.

A patient struggles to complete personal hygiene. What nursing intervention is most appropriate?

Break hygiene into simple, concrete steps, use visual cues, and reinforce progress with praise.

A patient refuses antipsychotic medication because they insist they are not ill. What may explain this, and how should the nurse respond?

Anosognosia may impair illness awareness.

• Build collaboration by connecting treatment to the patient's goals and discussing side effects without confrontation.

A patient is suspected of hiding or “cheek­ing” medication. What strategies may help?

Consider liquid or orally dissolving formulations when appropriate, and assess whether a long-acting injectable could support adherence.

A socially withdrawn patient avoids group activities. How should the nurse encourage interaction?

Start with low-anxiety conversation, then gradually offer activities without pressure.

What early warning signs of schizophrenia relapse should the patient and family learn to recognize?

Reduced sleep, social withdrawal, worsening concentration, and declining hygiene or self-care.

Why should patients with schizophrenia avoid marijuana?

Marijuana use can worsen psychotic symptoms and increase risk of psychosis, especially in vulnerable individuals.

Why should nurses monitor fluid intake in schizophrenia?

Some patients develop polydipsia, or compulsive excessive drinking, which can cause hyponatremia.

A patient who drinks excessive amounts of water becomes confused and restless. What complication should the nurse suspect?

Hyponatremia, or low blood sodium.

• Report the change promptly and assess neurological status and vital signs.

How can hyponatremia affect a patient with schizophrenia?

It can cause confusion, delirium, worsening psychosis, and potentially life-threatening neurological complications.

When is suicide risk particularly elevated in schizophrenia?

Around the first psychotic episode and following hospital discharge.

What should the nurse prioritize when caring for a patient with schizophrenia who expresses suicidal thoughts?

Immediate suicide-risk assessment and safety interventions, including assessment of intent, plan, access to means, and appropriate observation.

Which substance-use concerns are common in schizophrenia?

Alcohol and marijuana use are common; nicotine use is also highly prevalent. Screen for substance use and offer appropriate support.

Why is physical health monitoring especially important in schizophrenia?

Patients face increased risks of cardiovascular and metabolic illness and premature death, influenced by health behaviors, poverty, and barriers to care.

What factors can increase vulnerability to schizophrenia?

Genetic family history, prenatal complications, substance use, psychosocial stress, trauma, urban living, environmental exposures, and other developmental factors.

A patient with schizophrenia becomes socially withdrawn and stops showering. What should the nurse do first?

A. Assume the patient prefers isolation.
B. Assess for early relapse signs.
C. Immediately confront the patient.
D. Discontinue the antipsychotic.

C. Assess the command's content, intent, and immediate safety risk.
D. Encourage the patient to attend group therapy.

C. Assess the command's content, intent, and immediate safety risk.

A patient taking clozapine develops a fever and sore throat. What should the nurse do?

A. Reassure the patient that this is expected.
B. Promptly notify the prescriber and arrange urgent assessment.
C. Encourage increased caffeine intake.
D. Wait until the next routine appointment.

B. Promptly notify the prescriber and arrange urgent assessment.

A patient with schizophrenia drinks excessive water and develops confusion. Which complication is most concerning?

A. Hyperglycemia
B. Hyponatremia
C. Tardive dyskinesia
D. Akathisia

Which intervention is best for a patient who believes staff are plotting against them?

A. Prove the belief is false through debate.
B. Agree that staff are dangerous.
C. Acknowledge the fear without reinforcing the belief.
D. Ignore the patient.

C. Acknowledge the fear without reinforcing the belief.

What is the key nursing takeaway when a patient with schizophrenia begins withdrawing and neglecting hygiene?

Assess for relapse early, especially reduced sleep, social withdrawal, worsening concentration, and medication nonadherence.

What is the key nursing takeaway about suicide risk in schizophrenia?

Suicide risk is especially concerning around the first episode and after discharge. Assess suicidal thoughts and safety promptly.

A client has hallucinations, delusions, and disorganized speech for three months but continues working and caring for themselves. Which disorder is most consistent with this presentation?

Schizophreniform disorder. Symptoms last 1–6 months, and functioning may remain intact.

A client diagnosed with schizophreniform disorder continues experiencing symptoms for seven months. What should the healthcare provider do?

Reassess for schizophrenia, because the total duration has exceeded six months.

A client has schizophrenia-like symptoms for two months and returns to their usual level of functioning. Does this rule out schizophreniform disorder?

No. Recovery to baseline is possible with schizophreniform disorder.

A client has hallucinations and delusions for four months. Why can't the nurse distinguish schizophreniform disorder from schizophrenia based on symptoms alone?

Their symptoms can be similar; duration is the key distinction.

A client has psychotic symptoms lasting five months. Their family asks whether the client will definitely develop schizophrenia. What is the best response?

Not necessarily. Schizophreniform disorder may resolve or progress to schizophrenia; continued assessment is needed.

A client with schizophreniform disorder begins sleeping less, withdrawing socially, and struggling to concentrate. What should the nurse do?

Assess for worsening symptoms or progression and report significant changes to the healthcare team.

A client develops psychotic symptoms after using an illicit substance. Why should the healthcare provider investigate the substance history before diagnosing schizophreniform disorder?

Substance-induced psychosis must be ruled out before establishing the diagnosis.

A client with schizophreniform disorder asks whether treatment differs from schizophrenia treatment. What should the nurse explain?

Treatment approaches are similar, including antipsychotic medication and psychosocial support, with monitoring for symptom progression.

A client has had psychotic symptoms for six weeks but shows no clear decline in work or relationships. Can schizophreniform disorder still be considered?

Yes. Significant functional impairment is not always evident in schizophreniform disorder.

A client diagnosed with schizophreniform disorder is preparing for discharge. What teaching is most important?

Recognize early warning signs, including reduced sleep, social withdrawal, worsening concentration, and declining self-care, and seek help if they occur.

A client has hallucinations, delusions, and disorganized speech for four months. Medical and substance causes have been excluded. Which diagnosis best fits the duration?

A. Schizophrenia
B. Schizophreniform disorder
C. Delusional disorder
D. Brief psychotic disorder

B. Schizophreniform disorder

A client diagnosed with schizophreniform disorder continues experiencing psychotic symptoms seven months after onset. Which action is most appropriate?

A. Maintain the diagnosis without reassessment.
B. Discontinue treatment because the diagnosis changed.
C. Reassess for schizophrenia and other possible causes.
D. Assume the client is intentionally prolonging symptoms.

C. Reassess for schizophrenia and other possible causes.
