A patient diagnosed with schizophrenia has received fluphenazine decanoate twice a month for 3 years. The clinic nurse notes that the patient grimaces and constantly smacks both lips. The patient's neck and shoulders twist in a slow, snakelike motion. Which problem would the nurse suspect?

A) Agranulocytosis
B) Tardive dyskinesia
C) Tourette's syndrome
D) Anticholinergic effects

Fluphenazine decanoate is a first-generation antipsychotic medication. Tardive dyskinesia is a condition involving the face, trunk, and limbs that occurs more frequently with first-generation antipsychotics than second or third generation. Involuntary movements, such as tongue thrusting; licking; blowing; irregular movements of the arms, neck, and shoulders; rocking; hip jerks; and pelvic thrusts, are seen. These symptoms are frequently not reversible even when the drug is discontinued. The scenario does not present evidence consistent with the other disorders mentioned. Agranulocytosis is a blood disorder. Tourette's syndrome is a condition in which tics are present. Anticholinergic effects include dry mouth, blurred vision, flushing, constipation, and dry eyes.
