To calculate the ml/hour required for the bolus dose, first determine the concentration of the drug in the solution, which is 60 mg in 60 ml, or 1 mg/ml. For a 5 mg bolus dose, 5 ml of the solution is needed (since 1 mg is in 1 ml). To administer this over 4 minutes, convert the time to hours (4 minutes = 4/60 hours = 1/15 hours). The rate in ml/hour is then 5 ml divided by 1/15 hours, which equals 75 ml/hour.
