1.5 kcal/mL63 g protein/L90 mL/h16 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1.5 kcal/mL runs at 90 mL/h for 16 hours a day. How many kilocalories E does the patient receive per day?

90 mL/h16 h/day1.5 kcal/mL
E = kcal/day
2.Easy
1.5 kcal/mL1200 mL/day5 × ? mL5× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1200 mL of formula a day, given as 5 equal bolus feeds. What volume V is given in each bolus? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A woman is 165 cm tall and weighs 91 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 55 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 76% free water and runs at 90 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 4 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill man is 185 cm tall and weighs 122 kg. The practice protocol gives 11 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.

6.Hard
8 kgdextrose 10%28 mL/hGIR = ? mg/kg/min

Practice exercise (made-up values, not clinical guidance). A child who weighs 8 kg receives 10% dextrose at 28 mL/h. Find the glucose infusion rate GIR in mg/kg/min. Round to two decimal places.

GIR = mg/kg/min

Answer key

  1. 1. E = 2160 kcal/day
  2. 2. V = 240 mL
  3. 3. %IBW = 160 %
  4. 4. V = 93 mL
  5. 5. E = 1342 kcal/day
  6. 6. GIR = 5.83 mg/kg/min
