Enteral & parenteral nutrition calculations worksheet with answers

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1800 mL of formula a day, given as 8 equal bolus feeds. 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 40 g of protein per litre runs at 95 mL/h for 18 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 78 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 40 mL/h for 18 hours a day. A protein powder supplies 10 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). Use the Devine formula to find the ideal body weight IBW of a man who is 187 cm tall (1 in = 2.54 cm). Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 158 cm tall and weighs 138 kg. The practice protocol gives 13 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.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1500 mL of parenteral nutrition with final concentrations of 20% dextrose and 5% amino acids, plus 250 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.
