Final answer:
After major surgery, Mr. J. would need approximately 68 grams of protein per day based on his ideal body weight of 84.5kg. It's important to consult with a healthcare professional for accurate protein recommendations.
The orrect Option is; c) 100 grams/day.
Step-by-step explanation:
After major surgery, Mr. J. will need a higher intake of protein to support the healing and recovery process. The recommended daily protein intake for healthy adults is generally around 0.8 grams per kilogram of body weight. However, in the case of major surgery, the need for protein may be increased.
Using the provided information, Mr. J.'s ideal body weight (IBW) is given as 84.5kg. Therefore, a reasonable estimate for his protein intake would be around 68 grams per day (0.8 grams/kg x 84.5kg). This ensures that he has an adequate amount of protein to support tissue repair and immune function.
It's important to note that the specific protein requirements may vary depending on the individual, their underlying health conditions, and the type of surgery performed. It is always best to consult with a healthcare professional to determine the exact protein needs for a person after major surgery.
