1.2 kcal/mL1500 kcal/day? mL/h16 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1500 kcal a day from a tube feed that provides 1.2 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
2 kcal/mL84 g protein/L40 mL/h24 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 2 kcal/mL runs at 40 mL/h for 24 hours a day. How many kilocalories E does the patient receive per day?

E = kcal/day
3.Medium
154 cmwomanIBW = ? kg

Practice exercise (made-up values, not clinical guidance). Use the Devine formula to find the ideal body weight IBW of a woman who is 154 cm tall (1 in = 2.54 cm). Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1800 mL of parenteral nutrition with final concentrations of 25% dextrose and 5% amino acids, plus 250 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.
