1.5 kcal/mL63 g protein/L75 mL/h24 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1.5 kcal/mL runs at 75 mL/h for 24 hours a day. How many kilocalories E does the patient receive per day?

Practice exercise (made-up values, not clinical guidance). An 80 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 75 mL/h for 24 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 1200 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 3.5% amino acids, plus 250 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.
