A nurse is collecting data from a client who has schizophrenia and has been taking chlorpromazine for 8 years. The nurse notes choreiform or jerking uncontrolled movements, lip smacking, and spastic facial distortions. Which of the following conditions should the nurse document in her finding?

Choice A reason: Lockjaw refers to trismus, a condition where the jaw muscles spasm and prevent opening or closing of the mouth. This is not a typical side effect of long-term antipsychotic use and does not match the described involuntary facial movements. Choice B reason: Tardive dyskinesia is the correct diagnosis. It is a late-onset side effect of long-term antipsychotic therapy, especially with first-generation agents like chlorpromazine. It manifests as involuntary, repetitive movements such as lip smacking, choreiform movements, and facial distortions. These symptoms match the findings described in the scenario. Choice C reason: Akathisia is characterized by inner restlessness and an inability to stay still, often presenting as pacing or constant movement. It does not involve the involuntary facial movements described here. Choice D reason: Pseudoparkinsonism mimics Parkinson’s disease symptoms such as tremors, rigidity, and bradykinesia. It does not cause choreiform movements or lip smacking, so it does not fit the findings.
