2. Determine the energy requirements for a 65 YOF who is 2 days post coronary artery bypass graft (CABG). She can get out of bed only to use the bathroom. Height 5’3”, weight 140 lbs.

Answer 1

1.ENERGY REQUIREMENT FOR 25 year old male with Diabetes

The energy needs of a diabetic patient is same as that of non diabetic individuals. The aim is to attain and maintain a healthy body weight. About 55%-70% of the daily calory must be from the carbohydrate to adjust blood glucose levels

Also to maintain the health status an intake of dietary fibre with 20%-30% of total energy is also required

Here the persons occupation shows that he is leading a sedentary lifestyle

BMI=25.122(over weight)

Total energy = 81.64x 30=2449 cal

Protein =0.8 x 81.64=65.312 g

65.312 x 4 = 261 cal

Fats =28%

28 x 24.49=685.72÷9= 76g

Carbohydrate = 2449-(262+686)=2449-947=1502 cal= 62% of total calory

=376 gx

Question no 2

65 year old female, pist CABG

Lfestyle- light activities

BMI= 24.805( over weight

Since the patient is in her 2nd postoperative day, she may be on full liquid diet with normal energy requirements

So the total energy requiremnt is 63.5 × 30=1905 cal

With 55-70% of total energy derives from carbohydrates
