1.5 kcal/mL68 g protein/L95 mL/h18 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1.5 kcal/mL runs at 95 mL/h for 18 hours a day. How many kilocalories E does the patient receive per day?

95 mL/h18 h/day1.5 kcal/mL
E = kcal/day
2.Easy
1 kcal/mL1800 kcal/day6 × ? mL6× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1800 kcal a day from a formula that provides 1 kcal/mL. The daily amount is given as 6 equal boluses. What volume V is given in each bolus? Round to the nearest whole number.

V = mL
3.Medium
161 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 161 cm tall (1 in = 2.54 cm). Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A 68 kg adult (BMI below 30) needs 30 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). Over 24 hours a patient receives 2400 mL of parenteral nutrition with final concentrations of 12.5% dextrose and 3.5% amino acids, plus 500 mL of 10% lipid emulsion (1.1 kcal/mL). Find the non-protein energy NPC in kcal per day. Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 173 cm tall and weighs 132 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.

Answer key

  1. 1. E = 2565 kcal/day
  2. 2. V = 300 mL
  3. 3. IBW = 57.8 kg
  4. 4. R = 68 mL/h
  5. 5. NPC = 1570 kcal/day
  6. 6. P = 160 g/day
