1.Easy
1 kcal/mL1600 mL/day5 × ? mL5× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1600 mL of formula a day, given as 5 equal bolus feeds. What volume V is given in each bolus? Round to the nearest whole number.

1600 mL/day5 boluses
V = mL
2.Easy
2 kcal/mL84 g protein/L55 mL/h24 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 2 kcal/mL runs at 55 mL/h for 24 hours a day. How many kilocalories E does the patient receive per day?

55 mL/h24 h/day2 kcal/mL
E = kcal/day
3.Medium

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1800 mL of parenteral nutrition with final concentrations of 10% dextrose and 4% amino acids, plus 500 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.
