Final answer:
The drip rate is calculated by multiplying the volume (570 mL) by the tubing factor (20 gtt/mL) and dividing by the total time in minutes (660). The result is 17.27 gtt/min, which is rounded to 17 gtt/min as the drip rate.
Step-by-step explanation:
The student is asked to calculate the drip rate for a medical order using a given tubing factor. The order specifies a delivery of 570 mL of fluid over 11 hours. To find the drip rate in drops per minute (gtt/min), we use the formula:
Drip Rate (gtt/min) = (Volume (mL) × Tubing factor (gtt/mL)) / Total time (min)
First, convert the total time from hours to minutes: 11 hours × 60 minutes/hour = 660 minutes.
Next, apply the formula using the tubing factor of 20 gtt/mL:
Drip Rate = (570 mL × 20 gtt/mL) / 660 min
Drip Rate = 11400 gtt / 660 min
Drip Rate = 17.27 gtt/min (rounded to 17 gtt/min to the nearest whole number).
Therefore, the correct drip rate is 17 gtt/min.
