Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1500 kcal a day from a formula that provides 1 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.

Practice exercise (made-up values, not clinical guidance). A woman is 173 cm tall and weighs 72 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 75 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 84% free water and runs at 65 mL/h for 20 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 1500 mL of parenteral nutrition with final concentrations of 25% dextrose and 6% amino acids, plus 500 mL of 20% lipid emulsion (2 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). A critically ill man is 189 cm tall and weighs 195 kg. The practice protocol gives 14 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 22 kcal/kg of ideal body weight (Devine) per day if the BMI is above 50 kg/m². Find the energy goal E in kcal/day. Round to the nearest whole number.
