2 kcal/mL2400 kcal/day? mL/h20 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2400 kcal a day from a tube feed that provides 2 kcal/mL. The feed runs by pump for 20 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

1 kcal/mL1200 kcal/day4 × ? mL4× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1200 kcal a day from a formula that provides 1 kcal/mL. The daily amount is given as 4 equal boluses. What volume V is given in each bolus? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A woman is 183 cm tall and weighs 98 kg. Find the actual weight as a percentage of the ideal body weight, %IBW, using the Devine formula (1 in = 2.54 cm). Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A 65 kg patient needs 1.3 g of protein per kg a day. The tube feed contains 68 g of protein per litre and runs at 45 mL/h for 18 hours a day. A protein powder supplies 6 g of protein per scoop. How many scoops n a day are needed to cover the shortfall? Round up to a whole scoop.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2400 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 energy NPC in kcal per day. Round to the nearest whole number.

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 5% amino acids, plus 500 mL of 10% lipid emulsion (1.1 kcal/mL). Find the total energy E the patient receives in kcal per day. Round to the nearest whole number.
