After taking chlorpromazine (Thorazine) for 1 month, a client presents to an ED with severe muscle rigidity, tachycardia, and a temperature of 105oF (40.5?C)
Which medical diagnosis and treatment should a nurse anticipate when planning care for this client? 1. Neuroleptic malignant syndrome treated by discontinuing Thorazine and administering dantrolene (Dantrium)
2. Neuroleptic malignant syndrome treated by increasing Thorazine dosage and administering an antianxiety medication
3. Dystonia treated by administering trihexyphenidyl (Artane)
4. Dystonia treated by administering bromocriptine (Parlodel)
1
Rationale: The nurse should expect that an ED physician would diagnose the client with neuroleptic malignant syndrome and treat the client by discontinuing chlorpromazine and administering dantrolene. Neuroleptic malignant syndrome is a potentially fatal condition characterized by rigidity, fever, altered consciousness, and autonomic instability. The use of typical antipsychotics is largely being replaced by atypical antipsychotics because they have fewer side effects and present a lower risk.
