1 kcal/mL1400 kcal/day? mL/h12 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1400 kcal a day from a tube feed that provides 1 kcal/mL. The feed runs by pump for 12 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

1 kcal/mL44 g protein/L90 mL/h16 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 44 g of protein per litre runs at 90 mL/h for 16 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). Over 24 hours a patient receives 1500 mL of parenteral nutrition with final concentrations of 10% dextrose and 5% amino acids, plus 100 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.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 166 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.
