Which of the following is a characteristic of tardive dyskinesia?
Severe feelings of restlessness
Permanent involuntary movements of the face, tongue, and extremities
Muscle rigidity and spasms
Symptoms that resemble Parkinson's disease
The Correct Answer is B
A. Severe feelings of restlessness. This describes akathisia, a different extrapyramidal side effect of antipsychotics.
B. Permanent involuntary movements of the face, tongue, and extremities. Tardive dyskinesia is characterized by repetitive, involuntary movements, often affecting the mouth, face, and limbs, and is a long-term side effect of antipsychotic medications.
C. Muscle rigidity and spasms. This describes dystonia, another extrapyramidal symptom, but not tardive dyskinesia.
D. Symptoms that resemble Parkinson's disease. This describes drug-induced parkinsonism, which involves tremors, bradykinesia, and rigidity, not the repetitive movements seen in tardive dyskinesia.
