1 kcal/mL2100 kcal/day? mL/h20 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2100 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.

Practice exercise (made-up values, not clinical guidance). A 52 kg patient needs 1.8 g of protein per kg a day. The tube feed contains 40 g of protein per litre and runs at 45 mL/h for 24 hours a day. How many grams of extra protein ΔP a day are still needed? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2400 mL of parenteral nutrition with final concentrations of 20% dextrose and 4% amino acids, plus 500 mL of 10% lipid emulsion (1.1 kcal/mL). Find the total energy E the patient receives in kcal per day. Round to the nearest whole number.
