1 kcal/mL1200 kcal/day? mL/h20 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1200 kcal a day from a tube feed that provides 1 kcal/mL. The feed runs by pump for 20 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

2 kcal/mL1200 mL/day8 × ? mL8× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1200 mL of formula a day, given as 8 equal bolus feeds. What volume V is given in each bolus? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). An 87 kg patient needs 1.3 g of protein per kg a day. The tube feed contains 44 g of protein per litre and runs at 55 mL/h for 20 hours a day. A protein powder supplies 5 g of protein per scoop. How many scoops n a day are needed to cover the shortfall? Round up to a whole scoop.

Practice exercise (made-up values, not clinical guidance). A 64 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 84% free water and runs at 65 mL/h for 24 hours a day. The rest of the fluid is given as water flushes every 6 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 1800 mL of parenteral nutrition with final concentrations of 12.5% dextrose and 4.25% amino acids, plus 500 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.
