1.5 kcal/mL2400 kcal/day8 × ? mL8× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 2400 kcal a day from a formula that provides 1.5 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). Over 24 hours a patient receives 1200 mL of parenteral nutrition with final concentrations of 20% dextrose and 6% 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.
