Which interpretation and action are most appropriate for the client's new motor restlessness after starting aripiprazole?
1This is tardive dyskinesia; continue treatment and reassess after several months.
2This is anxiety from schizophrenia; increase stimulation and delay reporting it.
3This is neuroleptic malignant syndrome; begin cooling despite stable findings.
4This is likely akathisia; notify the prescriber for evaluation and management.✓ Correct answer
Explanation
An inner sense of restlessness with pacing and inability to sit still soon after starting aripiprazole is consistent with akathisia, a recognized adverse reaction. The nurse should notify the prescriber for assessment and medication management rather than increase the dose or treat for neuroleptic malignant syndrome.
Why this is correct Akathisia causes subjective inner restlessness with observable pacing or inability to remain seated. It is a commonly reported aripiprazole adverse reaction and merits prompt prescriber evaluation.
Easy analogy or mental picture The client feels as if an internal motor will not switch off.
Memory hook Akathisia equals an urge to move.
NCLEX decision rule Differentiate medication-induced movement syndromes by timing and pattern before choosing the escalation pathway.
Why the other choices are wrong Tardive dyskinesia features repetitive involuntary movements, anxiety does not explain the medication timing and classic pacing pattern, and neuroleptic malignant syndrome requires systemic features such as fever and rigidity.

Scenario A 32-year-old male on aripiprazole 15 mg PO daily for 2 weeks for schizophrenia reports being unable to sit still, constantly pacing, and feeling "jittery from the inside." Vital signs are stable. There is no fever, rigidity, or repetitive involuntary movement.
Akathisia — Subjective inner restlessness with observable motor restlessness; a common acute EPS of antipsychotics, especially aripiprazole and high-potency typicals.
Partial D2 agonist — Pharmacologic action of aripiprazole, brexpiprazole, and cariprazine — stabilizes dopamine signaling rather than fully blocking it; reduces EPS and metabolic risk.
Tardive dyskinesia — Late-onset involuntary repetitive movements (face, tongue, limbs) after months to years of antipsychotic therapy; treatable with valbenazine or deutetrabenazine.
