1.5 kcal/mL1200 kcal/day? mL/h16 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1200 kcal a day from a tube feed that provides 1.5 kcal/mL. The feed runs by pump for 16 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

2.Easy
1.5 kcal/mL1000 mL/day8 × ? mL8× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1000 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.

1000 mL/day8 boluses
V = mL
3.Medium
164 cmmanIBW = ? kg

Practice exercise (made-up values, not clinical guidance). Use the Devine formula to find the ideal body weight IBW of a man who is 164 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 175 cm tall and weighs 169 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.
