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

A. PO administration of divalproex: Divalproex is a mood stabilizer used primarily for bipolar disorder and seizure control; it does not address acute dystonic reactions or laryngeal spasms. B. PO administration of lorazepam: Lorazepam, an anxiolytic, may help with anxiety but is not the first-line treatment for acute dystonia, particularly when airway compromise like laryngeal spasm is present. C. IV Administration of benztropine: Benztropine, an anticholinergic, is the drug of choice for treating acute dystonic reactions, including dangerous laryngeal spasms, because it quickly reverses extrapyramidal symptoms. D. IV Administration of isotonic crystalloid fluid: IV fluids help with hydration and circulation but have no therapeutic effect on the muscle rigidity or spasms associated with an acute dystonic reaction.
