Enteral & parenteral nutrition calculations worksheet with answers

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 5 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 tube feed with 63 g of protein per litre runs at 80 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 70 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 76% free water and runs at 55 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). A 66 kg patient needs 1.2 g of protein per kg a day. The tube feed contains 84 g of protein per litre and runs at 50 mL/h for 16 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). A 60 kg adult receives 1000 mL of parenteral nutrition containing 25% dextrose, infused over 16 hours. Find the glucose infusion rate GIR in mg/kg/min. Round to two decimal places.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2000 mL of parenteral nutrition with final concentrations of 25% 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.
