A 25-year-old male is an inpatient at a psychiatric hospital with severe anxiety. He is having a severe episode of acute anxiety, and all non-pharmacological measures have been ineffective, with the patient considerably distressed, and all conservative measures have not worked. The decision is made by the team to use IM lorazepam, due to the current state of the patient. The man weighs 78kg. The hospital stocks 2mg/1ml vials of Lorazepam.
