2 kcal/mL84 g protein/L65 mL/h20 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 84 g of protein per litre runs at 65 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 1000 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 5% amino acids, plus 500 mL of 10% lipid emulsion (1.1 kcal/mL). Find the non-protein kilocalorie to nitrogen ratio NPC : N (the number x in x : 1). Round to the nearest whole number.
