1.2 kcal/mL2400 kcal/day? mL/h12 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2400 kcal a day from a tube feed that provides 1.2 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.

Practice exercise (made-up values, not clinical guidance). A woman is 154 cm tall and weighs 36 kg. Find the actual weight as a percentage of the ideal body weight, %IBW, using the Devine formula (1 in = 2.54 cm). Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 155 cm tall and weighs 125 kg. The practice protocol gives 11 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 23 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 woman is 164 cm tall and weighs 123 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.
