The key idea is to set the rate from what's left to infuse and the time left, then convert to drops per minute. After 4 hours, 600 mL have infused, so 450 mL remain to be given over 6 hours (360 minutes). The rate in mL per minute is 450 ÷ 360 = 1.25 mL/min. With a drop factor of 10 gtt/mL, the rate in drops per minute is 1.25 × 10 = 12.5 gtt/min. Since you can only administer whole drops, round to 13 gtt/min.
