1 kcal/mL40 g protein/L40 mL/h24 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 40 g of protein per litre runs at 40 mL/h for 24 hours a day. How many grams of protein P does the patient receive per day? Round to one decimal place.

40 mL/h24 h/day40 g/L
P = g/day
2.Easy
