A nurse is preparing to administer dextrose 5% in water IV to infuse at 100 mL/60 min. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min. (Round to the nearest whole number.).

The correct answer is A: 100 gtt/min. To calculate the IV flow rate, we first convert the prescribed volume (100 mL) and time (60 min) to drop factor per minute. 100 mL / 60 min = 1.67 mL/min. Then, we convert mL to drops using the drop factor (60 gtt/mL): 1.67 mL/min * 60 gtt/mL = 100.2 gtt/min. Rounding to the nearest whole number, the nurse should set the IV flow rate to 100 gtt/min.
Other choices (B-G) are incorrect as they are not calculated based on the given information and would lead to incorrect infusion rates.
