1 kcal/mL1500 kcal/day? mL/h18 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1500 kcal a day from a tube feed that provides 1 kcal/mL. The feed runs by pump for 18 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

2.Easy
1.5 kcal/mL63 g protein/L90 mL/h16 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 63 g of protein per litre runs at 90 mL/h for 16 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 1500 mL of parenteral nutrition with final concentrations of 12.5% dextrose and 5% amino acids, plus 250 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.
