A client diagnosed with schizophrenia is prescribed clozapine (Clozaril). Which client symptoms related to the side effects of this medication should prompt a nurse to intervene immediately?

A. Neuroleptic malignant syndrome, treated by discontinuing antipsychotic medications: The symptoms described (uncontrollable tongue movements, stiff neck, difficulty swallowing) are more indicative of tardive dyskinesia than neuroleptic malignant syndrome. Neuroleptic malignant syndrome is characterized by hyperthermia, autonomic dysregulation, altered mental status, and generalized muscle rigidity. Treatment involves discontinuing antipsychotic medications and supportive care.

B. Agranulocytosis treated by administration of clozapine (Clozaril): Agranulocytosis is a rare but serious side effect of clozapine, not a treatment for the symptoms described. The symptoms presented are more consistent with tardive dyskinesia.

C. Tardive dyskinesia treated by discontinuing antipsychotic medication: This is the correct answer. Tardive dyskinesia is a movement disorder characterized by involuntary and abnormal movements, including tongue protrusion and facial grimacing. It can result from long-term use of antipsychotic medications, and discontinuing or reducing the dose of the antipsychotic is a primary intervention.

D. Headache treated by administration of Hydrochlorothiazide: Hydrochlorothiazide is a diuretic used to treat conditions like high blood pressure and edema, not headache or the symptoms described, which are more indicative of tardive dyskinesia.

A. Allow the client to pace alone until physically tired: While pacing can be a coping mechanism, leaving the client alone may not be the most therapeutic approach. It is important for the nurse to provide support and assess the client's emotional state.

B. Walk with the client at a gradually slower pace: This is the correct answer. Walking with the client at a gradually slower pace allows the nurse to offer support and engage in therapeutic communication. It provides a calming presence and can assist the client in self-regulating their anxiety.

C. Have a staff member escort the client to her room: Escorting the client to her room might be perceived as restrictive or punitive. It is generally more beneficial to engage in supportive interventions and encourage coping strategies.

D. Instruct the client to sit down and stop pacing: Giving direct orders to stop pacing may increase anxiety and may not be an effective approach. It is often better to engage in a supportive manner and explore ways to help the client manage their anxiety.
