A nurse is preparing to administer 1 g cefazolin IVPB over 30 minutes. Available is cefazolin 1 g in 100 mL of DSW. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (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 = 30 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) / 30 min = 1000 gtt / 30 min = 33.333... gtt/min. Round to the nearest whole number. = 33 gtt/min.
