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.

1.2 kcal/mL55 g protein/L80 mL/h20 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 55 g of protein per litre runs at 80 mL/h for 20 hours a day. How many grams of protein P does the patient receive per day? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A 78 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 76% free water and runs at 85 mL/h for 18 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.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1800 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 5% amino acids, plus 250 mL of 10% lipid emulsion (1.1 kcal/mL). Find the non-protein energy NPC in kcal per day. Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1200 mL of parenteral nutrition with final concentrations of 20% dextrose and 4.25% 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.
