A nurse is caring for a client. Exhibits Which of the following actions should the nurse expect to take? Select all that apply.

A. Administer diphenhydramine 50 mg IM: The client exhibits signs of neuroleptic malignant syndrome (NMS), including hyperthermia, autonomic instability, altered mental status, and muscle rigidity. Diphenhydramine can help manage extrapyramidal symptoms and muscle rigidity while stabilizing the client, making it an appropriate intervention in the acute phase. B. Arrange for transport of the client to the nearest emergency department: NMS is a life-threatening medical emergency requiring immediate hospitalization for monitoring, intravenous fluids, and intensive management. The client’s elevated temperature, tachycardia, and altered mental status necessitate urgent transfer to a facility for providing acute care. C. Apply cool, wet washcloths to the client's forehead and axilla: Hyperthermia is a critical component of NMS. Applying cool, wet washcloths provides non-pharmacologic fever management to reduce core body temperature while awaiting transport and additional treatment interventions. This helps prevent further complications such as organ failure. D. Administer fluphenazine decanoate in the client's deltoid: Administering antipsychotics is contraindicated during NMS because these medications are the precipitating agents. Giving fluphenazine could worsen symptoms, increase rigidity, and exacerbate autonomic instability, so it must be avoided. E. Instruct the client to discontinue risperidone: While antipsychotics should be discontinued in NMS, simply instructing the client to stop taking risperidone is insufficient. Immediate medical intervention and supervised discontinuation in a hospital setting are required due to the risk of rapid deterioration and life-threatening complications.
