2 kcal/mL2100 kcal/day? mL/h16 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2100 kcal a day from a tube feed that provides 2 kcal/mL. The feed runs by pump for 16 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1500 mL of parenteral nutrition with final concentrations of 15% dextrose and 5% amino acids, plus 500 mL of 20% lipid emulsion (2 kcal/mL). Find the total energy E the patient receives in kcal per day. Round to the nearest whole number.
