A client is receiving 500 mg of metronidazole IVPB q8h. The metronidazole has been placed in 100 mL D5W to infuse over 45 minutes. The administration set delivers 10 gtt/mL. At what rate in gtt/min should the IV infuse? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Total volume = 100 mL. Infusion time = 45 minutes. Drop factor = 10 gtt/mL. Calculate the infusion rate in drops per minute (gtt/min). Infusion rate (gtt/min) = (Total volume (mL) x Drop factor (gtt/mL)) / Total time (min) = (100 mL x 10 gtt/mL) / 45 min = 1000 gtt / 45 min = 22.222... gtt/min. Round to the nearest whole number. = 22 gtt/min.
