1.5 kcal/mL1800 kcal/day6 × ? mL6× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1800 kcal a day from a formula that provides 1.5 kcal/mL. The daily amount is given as 6 equal boluses. What volume V is given in each bolus? Round to the nearest whole number.

1 kcal/mL40 g protein/L100 mL/h24 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 40 g of protein per litre runs at 100 mL/h for 24 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). A 63 kg adult (BMI below 30) needs 30 kcal/kg/day. The tube feed provides 1 kcal/mL and 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.

Practice exercise (made-up values, not clinical guidance). An 87 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 76% free water and runs at 90 mL/h for 18 hours a day. The rest of the fluid is given as water flushes every 4 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2400 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 non-protein kilocalorie to nitrogen ratio NPC : N (the number x in x : 1). Round to the nearest whole number.
