Rn Hesi Med Surg Dosage Calculations ( 55 Questions)
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 60 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
To answer this question, we need to calculate the infusion rate in gtt/min using the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
We are given the volume of the infusion as 1 liter and the drop factor as 60 gtt/mL. We need to convert the volume from liters to milliliters by multiplying by 1000 and convert the time from hours to minutes by multiplying by 60. Therefore, we get:
Volume (mL) = 1 L x 1000 mL/L
Volume (mL) = 1000 mL
Time (min) = 12 hours x 60 min/hour
Time (min) = 720 min
Now we can plug in the values into the formula and get:
Infusion rate (gtt/min) = 1000 mL x 60 gtt/mL / 720 min
Infusion rate (gtt/min) = 60000 gtt / 720 min
Infusion rate (gtt/min) = 83.3333 gtt/min
The nurse should regulate the infusion at 83 gtt/min. This is the numerical value and it is rounded to the nearest whole number, as instructed.
