CALCULATE FLOW RATE IN DROPS PER MINUTE:
Order: 1 L of 0.9% NS to infuse at 50 mL/hr.
Drop factor: 15 gtt/mL.
12 gtt/min
20 gtt/min
13 gtt/min
15 gtt/min
The Correct Answer is D
To calculate the flow rate in drops per minute, we can use the following formula:
Drops per minute = (Flow rate in mL/hour x Drop factor) / 60
Given that we have an order of 1 L of 0.9% NS to infuse at 50 mL/hr and a drop factor of 15 gtt/mL, we can calculate the flow rate as follows:
Drops per minute = (50 x 15) / 60 = **12.5 gtt/min**
Therefore, the correct answer is **d) 15 gtt/min**.

Correct Answer is C
Explanation
Step 1: Identify the given information
- Total volume to infuse = 100 mL
- Infusion time = 30 minutes
- Drop factor = 60 gtt/mL
Step 2: Use the formula for flow rate
Flow rate (gtt/min) = (Total Volume (mL) × Drop Factor (gtt/mL)) ÷ Infusion Time (min)
Step 3: Plug in the values
= (100 × 60) ÷ 30
Step 4: Solve step by step
- 100 × 60 = 6000
- 6000 ÷ 30 = 200
Correct Answer is A
Explanation
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.
