A patient experiences a sudden episode of severe anxiety. Which medication would be the expected drug to be given to help with the sudden episode of severe anxiety?

A. Lorazepam is a benzodiazepine that acts quickly to relieve acute anxiety, making it the medication of choice for sudden episodes of severe anxiety. B. Amitriptyline is a tricyclic antidepressant used for long-term management of depression and anxiety, not for rapid relief of acute anxiety. C. Buspirone is an anxiolytic effective for chronic anxiety but has a delayed onset of action and is not effective for sudden episodes. D. Desipramine is a tricyclic antidepressant primarily used for depression and certain chronic anxiety disorders, not for immediate relief of severe anxiety.
