2 kcal/mL1800 kcal/day? mL/h24 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1800 kcal a day from a tube feed that provides 2 kcal/mL. The feed runs by pump for 24 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A 71 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 70% free water and runs at 80 mL/h for 24 hours a day. The rest of the fluid is given as water flushes every 4 hours. What volume V is each flush? Round to the nearest whole number.
