A client retums from the post anesthesia care unit (PACU) with a bag of intravenous (IV) fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, "Continue the present IV over the next 7 hours." The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only).
