1.5 kcal/mL63 g protein/L65 mL/h20 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1.5 kcal/mL runs at 65 mL/h for 20 hours a day. How many kilocalories E does the patient receive per day?

Practice exercise (made-up values, not clinical guidance). A 59 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 81% free water and runs at 55 mL/h for 24 hours a day. The rest of the fluid is given as water flushes every 6 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 163 cm tall and weighs 119 kg. The practice protocol gives 12 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). A critically ill man is 169 cm tall and weighs 145 kg. The practice protocol gives 2 g of protein per kg of ideal body weight (Devine) per day if the BMI is 30 to under 40 kg/m², and 2.5 g/kg of ideal body weight per day if the BMI is 40 kg/m² or more. Find the protein goal P in g/day. Round to the nearest whole number.
