Question 1 of 5
A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1L to infuse at 100 mL/hr. The nurse is using microtubing. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round to the nearest whole number.)
Correct Answer: 100
Rationale:
To calculate the manual IV infusion rate in drops per minute (gtt/min) when using microtubing, you can use the following formula: IV Drip Rate (gtt/min) = (Volume to be infused (mL) x Drop factor (gtt/mL)) / Time (min). Since microtubing typically has a drop factor of 60 gtt/mL, and the nurse is looking to infuse 1L (1000 mL) of solution at a rate of 100 mL/hr, the time to infuse 100 mL would be 60 minutes. Plugging these values into the formula gives: IV Drip Rate (gtt/min) = (100 mL x 60 gtt/mL) / 60 min, which simplifies to 100 gtt/min.
