For a patient receiving continuous insulin therapy, how many units of rapid-acting insulin would they receive over a 24-hour period at a rate of 5 units per hour?

100 units
120 units
140 units
160 units

The correct answer is: 100 units

The calculation of how many units of rapid-acting insulin a patient would receive over a 24-hour period involves simple multiplication. If the patient is receiving insulin at a rate of 5 units per hour, you multiply that hourly rate by the total number of hours in a day. So for a 24-hour period, the calculation would be: 5 units/hour × 24 hours = 120 units. This means that over a full day, at this continuous infusion rate, the patient would receive a total of 120 units of rapid-acting insulin. This demonstrates the importance of understanding dosage calculations in patient care, especially for those managing diabetes with insulin therapy. It is crucial for healthcare professionals to accurately calculate and monitor insulin dosages to ensure safe and effective treatment.
