A nurse is assessing a client who has schizophrenia which has been treated with fluphenazine for several years. Which of the following findings should the nurse document as manifestations of tardive dyskinesia (TD)?

A. Constant tapping of feet when sitting is more likely to be a manifestation of a repetitive, purposeless movement, but it is not characteristic of tardive dyskinesia (TD). TD typically involves involuntary, repetitive movements, especially of the face and mouth. B. Twisting tongue movements are a hallmark sign of tardive dyskinesia (TD). TD often presents with involuntary movements of the face, lips, tongue, and sometimes the limbs. These twisting, writhing, or jerking movements are the most characteristic signs of TD. C. Sudden onset of high fever is a critical symptom associated with neuroleptic malignant syndrome (NMS), not tardive dyskinesia. NMS is a potentially life-threatening condition that can occur with antipsychotic use and involves high fever, altered mental status, muscle rigidity, and autonomic dysfunction. D. Shuffling gait is commonly associated with pseudoparkinsonism, which is another side effect of antipsychotic medications but is not a typical sign of tardive dyskinesia. Pseudoparkinsonism involves symptoms like tremors, rigidity, and bradykinesia.
