1.Easy
1 kcal/mL40 g protein/L95 mL/h16 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1 kcal/mL runs at 95 mL/h for 16 hours a day. How many kilocalories E does the patient receive per day?

95 mL/h16 h/day1 kcal/mL
E = kcal/day
2.Easy
1.5 kcal/mL63 g protein/L60 mL/h20 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 63 g of protein per litre runs at 60 mL/h for 20 hours a day. How many grams of protein P does the patient receive per day? Round to one decimal place.

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 4% amino acids, plus 250 mL of 20% lipid emulsion (2 kcal/mL). Find the non-protein energy NPC in kcal per day. Round to the nearest whole number.
