Instructions: Calculate the flow rate in units/hr (Equipment used is programmable in whole units/hr). Order: 100,000 units of Heparin in 1,000 mL to infuse at 50 mL/hr. Calculate the rate in units/hr.
5000 units/hr
500 units/hr
2000 units/hr
2500 units/hr
2500 units/hr
The Correct Answer is A
To solve this problem, we need to find the concentration of heparin in the solution and then multiply it by the infusion rate. The concentration of heparin is the amount of heparin divided by the volume of the solution. In this case, the concentration is:
100,000 units / 1,000 ml = 100 units/ml
The infusion rate is given as 50 ml/hr. To find the flow rate in units/hr, we multiply the concentration by the infusion rate:
100 units/ml * 50 ml/hr = 5000 units/hr
Therefore, the flow rate in units/hr is 5000 units/hr.

Correct Answer is A
Explanation
Step 1: Identify the total volume to be infused.
- Total volume = 2,000 mL
Step 2: Identify the total time for infusion.
- Total time = 24 hours
Step 3: Calculate the flow rate in mL/hr.
- Flow rate = Total volume ÷ Total time
- Flow rate = 2,000 mL ÷ 24 hours
Step 4: Perform the division.
- 2,000 ÷ 24 = 83.3333…
Step 5: Round to the nearest whole number since the equipment is programmable in whole mL/hr.
- Rounded flow rate = 83 mL/hr
So, the flow rate is 83 mL/hr.
