2 kcal/mL84 g protein/L75 mL/h16 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 2 kcal/mL runs at 75 mL/h for 16 hours a day. How many kilocalories E does the patient receive per day?

75 mL/h16 h/day2 kcal/mL
E = kcal/day
2.Easy
1.2 kcal/mL1000 mL/day? mL/h24 h/day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1000 mL of tube feed a day, run by pump over 24 hours. 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 73 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 81% free water and runs at 85 mL/h for 20 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). An 88 kg patient needs 1.5 g of protein per kg a day. The tube feed contains 40 g of protein per litre and runs at 75 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 2000 mL of parenteral nutrition with final concentrations of 15% dextrose and 3.5% 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.
