A nurse is preparing to administer dextrose 5% in water IV to infuse at 150 mL/hr. The drop factor on the manual IV tubing is 15 gtt/mL. The nurse should set the IV flow rate 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.)

To calculate the IV flow rate in gtt/min, the nurse needs to use the following formula: IV flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min). In this case, the volume is 150 mL, the drop factor is 15 gtt/mL, and the time is 60 min. Plugging these values into the formula, we get: IV flow rate (gtt/min) = 150 x 15 / 60. Simplifying, we get: IV flow rate (gtt/min) = 37.5. Therefore, the nurse should set the IV flow rate to deliver 38 gtt/min.
