What is the recommended dosing rate in mL/hr for a continuous regular insulin infusion of 100 units in 100 mL saline for 7 units/hour?

To determine the recommended dosing rate for a continuous regular insulin infusion of 100 units in 100 mL saline at a rate of 7 units/hour, we first need to calculate the concentration of insulin in the solution.

In this solution, 100 units of insulin are dissolved in 100 mL of saline, meaning that there are 1 unit of insulin per mL of saline. Therefore, to deliver 7 units of insulin per hour, the infusion should provide 7 mL of the saline solution since the concentration is 1 unit/mL.

To maintain a continuous infusion at this rate, the correct dosing rate in mL/hr is exactly 7 mL/hr. This matches the amount of solution required to deliver the precise dose of insulin needed, thus providing the necessary therapeutic effect while ensuring patient safety and efficacy in treatment.

This calculation illustrates the alignment between the concentration of the insulin solution and the desired infusion rate, emphasizing the importance of accurate dosing in intravenous medication administration.
