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 C
Explanation
Step 1: Identify the given information
- Ordered dose = 6,000 units
- Available concentration = 5,000 units per 1 mL
Step 2: Set up the ratio and proportion equation
- 5,000 units ÷ 1 mL = 6,000 units ÷ X mL
Step 3: Solve for X
- (6,000 × 1) ÷ 5,000 = X
- 6,000 ÷ 5,000 = 1.2 mL
Step 4: Round to the nearest tenth
- 1.2 mL (already rounded)
