Given that,
Age of Mrs Jones = 55 years
Height = 5'6''
Weight = 140 lb = 63.6 kg
The tube feeding ordered for her provides:
1 cal/mL and 40 grams of protein/1000 mL.
It is infusing at a rate of 50 mL/hour for 24 hour.
Suppose, We need to find her protein needs per day
We know that,
According to the DRI, 0.8 gram of protein per kg of body weight is required protein per day.
Thus,
We need to calculate her protein needs per day
Using formula for protein needs per day

Put the value of weight


Hence, 50.88g of protein are needed per day for Mrs jones.
