Final answer:
To calculate the infusion rate for D5W at 15ml/hr with an IV set that has a drop factor of 60 drops per ml, you multiply the volume by the drop factor and then divide by 60 to convert the rate to drops per minute, resulting in an infusion rate of 15 drops per minute.
Step-by-step explanation:
The student is asking how to determine the infusion rate of D5W at a given administration rate using an IV set with a specific drop factor. The D5W is to be infused at 15ml/hr, and the IV administration set delivers 60 drops (gtts) per ml. The infusion rate is commonly calculated using the formula: (Volume to be infused in mL/hr) x (Drop factor in gtts/mL) = Infusion rate in gtts/min. Therefore, we multiply the order of 15 mL/hr by the drop factor of 60 gtts/mL.
By performing this calculation:
- 15 mL/hr x 60 gtts/mL = 900 gtts/hr
Since we need the rate in minutes, we divide by 60:
- 900 gtts/hr รท 60 minutes/hr = 15 gtts/min
The infusion rate will hence be 15 gtts/min.
