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
To solve this problem, we need to find the infusion rate in ml/min by dividing the volume of the solution by the duration of the infusion. In this case, the infusion rate is:
100 ml / 60 min = 1.67 ml/min
Then, we need to multiply the infusion rate by the drop factor to find the flow rate in gtt/min. The drop factor is given as 10 gtt/ml. Therefore, the flow rate is:
1.67 ml/min * 10 gtt/ml = 16.7 gtt/min
However, since we cannot administer partial drops, we need to round the answer to the nearest whole number. The closest whole number to 16.7 gtt/min is 17 gtt/min, so we round up. Therefore, the flow rate in gtt/min is 17 gtt/min.
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.
