R = mL/h
2.Easy
1.5 kcal/mL1800 kcal/day4 × ? mL4× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1800 kcal a day from a formula that provides 1.5 kcal/mL. The daily amount is given as 4 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 1000 mL of parenteral nutrition with final concentrations of 15% dextrose and 4% amino acids, plus 100 mL of 20% lipid emulsion (2 kcal/mL). Find the non-protein kilocalorie to nitrogen ratio NPC : N (the number x in x : 1). Round to the nearest whole number.
