2 kcal/mL84 g protein/L40 mL/h20 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 2 kcal/mL runs at 40 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 patient needs 2000 kcal a day from a tube feed that provides 1 kcal/mL. The feed runs by pump for 18 hours a day. 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). An 86 kg adult (BMI below 30) needs 25 kcal/kg/day. The tube feed provides 1.5 kcal/mL and runs by pump for 20 hours a day. 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 78 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 90 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 175 cm tall and weighs 147 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.
