Nokea
A client on a psychiatric care unit approaches the nurse and complains of muscle spasms in his neck, stiffness in other muscles, and that his eyes are rolling upward. The client had two p.r.n. doses of haloperidol (Haldol) in the last 6 hours. Of the drugs that have been ordered for the client as needed (see chart), the nurse should administer:
Correct Answer: D
Rationale: Dystonic adverse effects of haloperidol, especially oculogyric crises, are painful and frightening. I.M. benztropine is the fastest and most effective drug for managing dystonia. Lorazepam is an antianxiety medication and is not effective for treatment of dystonia. Although amantadine and diphenhydramine can be used for extrapyramidal symptoms, oral medications do not work as quickly, and amantadine may worsen psychotic symptoms.
