A client is receiving 10 mL/hr of a prescribed regular insulin infusion. The label on the bag reads 50 units of regular insulin in 100 mL of 0.9% saline. How many units of insulin is the client receiving every hour? Fill in the blank. Round your answer to the nearest whole number.
A.
5 units/hour
B.
10 units/hour
C.
20 units/hour
D.
15 units/hour
The correct answer and Explanation is :
To determine how many units of insulin the client is receiving every hour, we need to follow these steps:
- Identify the concentration of insulin in the infusion:
- The insulin infusion bag contains 50 units of insulin in 100 mL of 0.9% saline.
- Calculate the concentration of insulin per mL:
- The concentration is determined by dividing the total units of insulin by the total volume of the solution.
- Concentration (units/mL) = Total units of insulin / Total volume of solution
- Concentration = 50 units / 100 mL
- Concentration = 0.5 units/mL
- Determine the rate of infusion in mL per hour:
- The client is receiving an infusion at a rate of 10 mL/hr.
- Calculate the total units of insulin the client is receiving every hour:
- To find this, multiply the infusion rate (in mL/hr) by the concentration of insulin (units/mL).
- Units/hour = Infusion rate (mL/hr) × Concentration (units/mL)
- Units/hour = 10 mL/hr × 0.5 units/mL
- Units/hour = 5 units/hr
Therefore, the client is receiving 5 units of insulin every hour.
So, the correct answer is:
A. 5 units/hour
Explanation:
To ensure accurate insulin delivery, it’s important to understand the concentration of the insulin solution and the rate at which it’s infused. The concentration of insulin in the bag tells us how many units of insulin are present per mL of solution. By knowing the infusion rate, we can calculate the total units of insulin being administered each hour by multiplying the rate by the concentration. This method ensures precise dosing and helps in maintaining effective glycemic control for the patient.
