A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 500 mL IV to infuse over 4 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should adjust 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.)
