Enteral & parenteral nutrition calculations worksheet with answers

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1800 mL of tube feed a day, run by pump over 20 hours. 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). A tube feed with 63 g of protein per litre runs at 65 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 76 kg patient needs 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 20 hours a day. A protein powder supplies 5 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 53 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 84% free water and runs at 75 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 8 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 176 cm tall and weighs 176 kg. The practice protocol gives 13 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 25 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.

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 10% lipid emulsion (1.1 kcal/mL). Find the non-protein energy NPC in kcal per day. Round to the nearest whole number.
