A nurse is preparing to administer dextrose 5% in water (D5W) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/ml. The nurse should set the manual 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.)

To calculate the correct infusion rate in gtt/min, we can use the formula: (Volume to be infused in mL / Time in minutes) x Drop factor. In this case, we have 150mL to be infused over 180 minutes (3 hours) with a drop factor of 10 gtt/ml. So, (150 / 180) x 10 = 8 gtt/min. This ensures the D5W is delivered at the prescribed rate. Other choices are incorrect because they do not result from the correct calculation based on the given parameters.
