A client receiving antipsychotics complains of uncontrollable movements. Which long-term side effect is the client likely experiencing?

Choice A reason: Pseudoparkinsonism is an extrapyramidal side effect characterized by tremors, bradykinesia, and rigidity. However, it is typically considered an intermediate or short-term side effect that appears within days to weeks of starting medication and usually resolves upon discontinuation or dose reduction, rather than being a permanent long-term manifestation. Choice B reason: Tardive dyskinesia is a potentially irreversible long-term side effect of prolonged antipsychotic use, particularly first-generation agents. It involves involuntary, repetitive movements such as lip-smacking, tongue protrusion, and grimacing. It results from dopamine receptor supersensitivity in the nigrostriatal pathway after years of chronic dopamine blockade and receptor upregulation. Choice C reason: Akathisia is characterized by a distressing internal sense of restlessness and an urgent need to move, often manifesting as pacing or inability to sit still. While it can persist, it is generally classified as an acute or subacute extrapyramidal symptom rather than the classic long-term choreoathetoid movement disorder. Choice D reason: Acute dystonia involves sudden, involuntary muscle contractions of the face, neck, or trunk, often occurring within the first few days of antipsychotic initiation. Because it occurs so early in the treatment trajectory, it is categorized as an acute emergency rather than a late-onset or long-term complication of therapy.
