Dosage calculation rn critical care proctored assessment 3.2 ( 35 Questions)
A nurse is preparing to administer 0.9% sodium chloride mL IV to infuse over 4 hr to a client. The drop factor of the manual IV tubing 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many git/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 6
Calculate the Total Infusion Time in Minutes:
The infusion is to be delivered over 4 hours.
There are 60 minutes in 1 hour.
Total infusion time: 4 hours x 60 minutes/hour = 240 minutes
Calculate the Drip Rate (gtt/min):
We'll use the following formula:
Drip Rate (gtt/min) = (Total Volume (mL) x Drop Factor (gtt/mL)) / Total Infusion Time (minutes)
Plug in the Values and Calculate:
Drip Rate (gtt/min) = (100 mL x 15 gtt/mL) / 240 minutes
Drip Rate (gtt/min) = 1500 gtt / 240 minutes
Drip Rate (gtt/min) = 6.25 gtt/min
Round to the Nearest Whole Number:
6 gtt/min
