1 kcal/mL2000 kcal/day? mL/h18 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2000 kcal a day from a tube feed that provides 1 kcal/mL. The feed runs by pump for 18 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 tube feed that provides 2 kcal/mL runs at 35 mL/h for 16 hours a day. How many kilocalories E does the patient receive per day?

Practice exercise (made-up values, not clinical guidance). A 68 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 84% free water and runs at 85 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 8 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1000 mL of parenteral nutrition with final concentrations of 12.5% dextrose and 6% amino acids, plus 250 mL of 20% lipid emulsion (2 kcal/mL). Find the non-protein kilocalorie to nitrogen ratio NPC : N (the number x in x : 1). Round to the nearest whole number.
