A charge nurse is instructing a newly licensed nurse about mental health disorders. Which of the following statements by the nurse indicates an understanding of mental health disorders?

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. Priority. The patient is exhibiting severe depression, weight loss, and expressing hopelessness, which are all indicators of an increased risk for suicide. Assessing and addressing the risk for suicide is crucial to ensuring the safety and well-being of the patient.

B. Incorrect. While the patient may be at risk for injury due to factors such as poor nutrition and potential self-harm, the immediate concern in this case is the risk for suicide, given the patient's severe depression and expressed hopelessness.

C. Incorrect. Powerlessness may be a relevant nursing diagnosis for individuals experiencing depression, but the immediate concern in this case is the risk for suicide. Addressing the patient's sense of powerlessness can be part of the broader care plan, but it's not the priority.

D. Incorrect. While the patient has experienced significant weight loss, the priority at this time is addressing the risk for suicide. Once the immediate safety concern is addressed, nutritional concerns can be addressed as part of the overall care plan.
