A 22-yeаr-оld pаtient whо weighs 62kg is аdmitted tо hospital after taking an overdose of propranolol tablets. She admits to taking 28 propranolol 40mg tablets. The patient is prescribed intravenous glucagon and given an initial bolus of 10mg over 10 minutes. Following the bolus, she is prescribed an intravenous infusion at a dose of 50microgram/kg/hour for 60 minutes. The glucagon solution used for the infusion is prepared at a concentration of 1mg/mL. How many milligrams of the glucagon will the patient receive in total? Give your answer to ONE (1) decimal place.
