📒 The 1-minute cheat sheet
📌 Types
Typical: haloperidol → ↑EPS risk
Atypical: -apine/-idone → metabolic
Block dopamine D2 receptors
📌 Eps
Acute dystonia → give benztropine
Akathisia = restless pacing
Tardive dyskinesia = lip smacking
🚩 Report
NMS: high fever, rigid, ↑CK
Clozapine → agranulocytosis, monitor WBC
🎓 Teach
Rise slowly → orthostatic ↓BP
Weight, glucose, lipids checks
📚 Antipsychotics — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Antipsychotics treat schizophrenia, psychosis, and bipolar mania by blocking dopamine. Typical (first-generation) agents like haloperidol cause more extrapyramidal symptoms, while atypical (second-generation) agents like risperidone and olanzapine cause more metabolic effects. The most dangerous adverse effect is neuroleptic malignant syndrome. Memory aid: typicals cause movement problems (EPS), atypicals cause metabolic weight/sugar problems.

Key points
Understand these first
Extrapyramidal symptoms (EPS) include acute dystonia, akathisia (restlessness), pseudoparkinsonism, and tardive dyskinesia (often irreversible involuntary movements).
Neuroleptic malignant syndrome (NMS) is a life-threatening reaction with high fever, severe muscle rigidity, altered mental status, and autonomic instability.
Atypical agents commonly cause weight gain, hyperglycemia, and elevated lipids (metabolic syndrome).
Clozapine carries a risk of agranulocytosis, requiring regular white blood cell and absolute neutrophil count monitoring.
Anticholinergic effects (dry mouth, constipation, urinary retention, blurred vision) and orthostatic hypotension are common.
Full therapeutic effect on psychotic symptoms may take several weeks.
✅
Nursing priorities
What to do, in order
Assess for extrapyramidal symptoms and abnormal involuntary movements (such as with the AIMS scale).
Monitor temperature, vital signs, and muscle tone for signs of neuroleptic malignant syndrome.
Monitor weight, blood glucose, and lipids, especially with atypical agents.
Monitor WBC and ANC for patients on clozapine and report drops promptly.
Implement fall precautions for orthostatic hypotension and treat anticholinergic effects.
🚩
Red flags — report now
Escalate immediately
Neuroleptic malignant syndrome (high fever, rigidity, altered consciousness, unstable vitals) is a medical emergency requiring the drug to be stopped immediately.
Acute dystonia such as muscle spasms of the neck, jaw, or back, or oculogyric crisis.
Signs of agranulocytosis in clozapine patients such as sore throat, fever, and infection.
Tardive dyskinesia, which may be irreversible, requires prompt provider notification.

Labs & values
Numbers to know
WBC (5,000-10,000/mm3) and ANC for clozapine - agranulocytosis
Blood glucose (fasting 70-99 mg/dL)
Lipid panel for atypical agents

Patient teaching
What patients must know
Rise slowly to avoid dizziness, and do not stop the medication abruptly.
Report fever, muscle stiffness, sore throat, or abnormal movements right away.
Use sunscreen due to photosensitivity, and attend all blood-monitoring appointments if on clozapine.
❓ Antipsychotics: NCLEX FAQs
What are the priority nursing interventions for Antipsychotics?
Assess for extrapyramidal symptoms and abnormal involuntary movements (such as with the AIMS scale). Monitor temperature, vital signs, and muscle tone for signs of neuroleptic malignant syndrome. Monitor weight, blood glucose, and lipids, especially with atypical agents. Monitor WBC and ANC for patients on clozapine and report drops promptly.
What are the warning signs of Antipsychotics a nurse must report?
Neuroleptic malignant syndrome (high fever, rigidity, altered consciousness, unstable vitals) is a medical emergency requiring the drug to be stopped immediately. Acute dystonia such as muscle spasms of the neck, jaw, or back, or oculogyric crisis. Signs of agranulocytosis in clozapine patients such as sore throat, fever, and infection. Tardive dyskinesia, which may be irreversible, requires prompt provider notification.
What do I need to know about Antipsychotics for the NCLEX?
