The nurse reviewing a patient’s medication list recognized which one as the antipsychotic?

Antipsychotic medications, particularly both typical and atypical agents, can cause a range of adverse effects beyond extrapyramidal symptoms (EPS). Nurses must monitor patients for neurological complications, metabolic disturbances, and cardiovascular risks to ensure early detection and prevention of long-term harm.

Rationale for correct answer:

A. Seizures:
Some antipsychotics, especially at higher doses or in susceptible patients, lower the seizure threshold, increasing the risk of seizure activity. Regular neurological assessment and monitoring for unusual movements or episodes of loss of consciousness are critical.

D. Dyslipidemia:
Atypical antipsychotics can disrupt lipid metabolism, leading to elevated cholesterol and triglyceride levels. This increases the risk of cardiovascular disease, making regular lipid panel monitoring an essential nursing responsibility.

E. Hyperglycemia:
Antipsychotic therapy, particularly with atypical agents, may impair glucose regulation, causing hyperglycemia or new-onset diabetes mellitus. Monitoring blood glucose and educating patients on signs of hyperglycemia are necessary to prevent complications.

Rationale for incorrect answer:

B. Weight loss:
Weight loss is uncommon; most antipsychotics are associated with weight gain, not loss.

C. Chronic fatigue:
While sedation may occur, chronic fatigue is not a primary adverse effect requiring routine monitoring in the same way as seizures, dyslipidemia, or hyperglycemia.

Take-home points:

• Monitor for neurological complications such as seizures during antipsychotic therapy.
• Assess metabolic parameters, including lipid profiles and blood glucose levels, regularly.
• Early detection of adverse effects can prevent long-term complications and improve patient safety.

Atypical antipsychotics, also known as second-generation antipsychotics, are commonly prescribed to treat psychotic disorders, including schizophrenia and bipolar disorder. These medications work by blocking dopamine and serotonin receptors, which helps reduce both positive and negative symptoms of psychosis while generally causing fewer extrapyramidal symptoms compared to first-generation antipsychotics. Nurses must monitor clients for therapeutic effects, metabolic changes, and other adverse reactions when administering these drugs.

Rationale for correct answer:

A. clozapine (Clozaril): Clozapine is a second-generation antipsychotic that blocks dopamine and serotonin receptors. It is effective for treatment-resistant schizophrenia and helps reduce hallucinations and delusions. Monitoring for agranulocytosis is essential.

D. olanzapine (Zyprexa): Atypical antipsychotic that acts on dopamine and serotonin receptors, helping reduce psychotic symptoms and improve mood. Metabolic monitoring is required due to risks of weight gain, diabetes, and dyslipidemia.

E. aripiprazole (Abilify): Atypical antipsychotic with a partial dopamine agonist effect, useful for schizophrenia, bipolar disorder, and as an adjunct in depression. It has a lower risk of EPS but still requires monitoring for akathisia and metabolic changes.

Rationale for incorrect answer:

B. fluphenazine (Prolixin): This is a first-generation antipsychotic. It primarily blocks dopamine and is associated with a higher risk of extrapyramidal symptoms and tardive dyskinesia, making it distinct from atypical antipsychotics.

C. haloperidol (Haldol): Also a first-generation antipsychotic, haloperidol is potent for positive symptoms of psychosis but carries a significant risk of EPS and neuroleptic malignant syndrome, unlike atypical agents.

Take-home points:

• Atypical antipsychotics treat both positive and negative symptoms of psychosis while generally causing fewer motor side effects.
• Metabolic monitoring is essential due to risks of weight gain, hyperglycemia, and dyslipidemia.
• First-generation antipsychotics (fluphenazine, haloperidol) primarily target dopamine and have a higher risk of extrapyramidal side effects.
