A client experiencing an acute dystonic reaction presents with a laryngeal spasm. Which treatment should the nurse prepare?

A. Divalproex is an anticonvulsant and is not indicated for the treatment of acute dystonic reactions. B. IV isotonic crystalloid fluid is used for hydration but is not the primary treatment for dystonic reactions. C. Lorazepam is a benzodiazepine, which may be used for anxiety or seizure activity, but is not effective for managing dystonic reactions. D. Benztropine is an anticholinergic medication used to treat acute dystonic reactions, including those causing laryngeal spasms. It works by reducing the excessive cholinergic activity that leads to these symptoms.
