Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 2400 kcal a day from a formula that provides 1 kcal/mL. The daily amount is given as 8 equal boluses. What volume V is given in each bolus? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A 53 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 60 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). Over 24 hours a patient receives 2400 mL of parenteral nutrition with final concentrations of 25% 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.
