ATI 240L Pharm lab final exam ( 20 Questions)
A nurse is preparing to administer dextrose 5% in water (D,W) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is the nurse should set the manual IV infusion to deliver how gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use trailing zero.)
Correct Answer: 8
Rationale:
Determine the total volume to be infused.
The nurse is preparing to administer 150 mL of dextrose 5% in water (DW).
Calculate the infusion rate in mL/min.
The infusion time is 3 hours, which is equivalent to 3 x 60 = 180 minutes.
Infusion rate = Total volume / Infusion time = 150 mL / 180 min = 0.83 mL/min
Apply the drop factor to find the drip rate in gtt/min.
Drop factor of the tubing is 10 gtt/mL.
Drip rate = Infusion rate (mL/min) x Drop factor (gtt/mL) = 0.83 mL/min x 10 gtt/mL = 8.3 gtt/min
Round the drip rate to the nearest whole number.
Drip rate = 8 gtt/min
