A patient has an order for 1000mL of D5W to infuse at 90 mL/h. The tubing drop factor is 15 gtts/mL. Calculate the drops per minute. Round to the nearest whole number.

Identify the infusion rate in milliliters per hour (mL/hr) and the drop factor. Infusion Rate: 90 mL/hr Drop Factor: 15 gtts/mL Calculate the infusion rate in drops per minute (gtt/min). Rate (gtt/min) = (Infusion Rate (mL/hr) x Drop Factor (gtts/mL)) / 60 minutes/hour = (90 mL/hr x 15 gtts/mL) / 60 min/hr = 1350 / 60 = 22.5 gtt/min. Round the answer to the nearest whole number. = 23 gtt/min.
