To calculate the flow rate, we need to determine the total number of drops needed to infuse 1000 mL of D5W 0.45% NS over 8 hours and then divide it by the total number of hours.
First, we need to convert 8 hours to minutes:
8 hours × 60 minutes/hour = 480 minutes
Next, we need to determine the total number of drops used to infuse 1000 mL. We can use the drop factor:
Total number of drops = 1000 mL × 15 gtts/mL
Total number of drops = 15000 gtts
Finally, we divide the total number of drops (15000 gtts) by the total number of minutes (480 minutes) to calculate the flow rate:
Flow rate = 15000 gtts ÷ 480 min
Flow rate = 31.25 gtts/min
So, the flow rate is 31.25 gtts/min.
Order: 1000 mL D5W 0.45% NS over 8 hours
Drop factor: 15gtts / mL
