Question

Quizplus · Accepted Answer

To deliver a 3 mg dose of morphine over a 3-minute period, we need to calculate the flow rate in ml/hour. Assuming a standard concentration of morphine (which is not provided in the question but commonly is 1 mg/ml for calculation purposes), to administer 3 mg over 3 minutes, we need 3 ml of the solution. To convert the flow rate to ml/hour, we use the formula: (Volume in ml / Time in hours). Since we're delivering over 3 minutes, we convert this to hours (3 minutes = 0.05 hours). Thus, (3 ml / 0.05 hours) = 60 ml/hour.
