Final answer:
Mr. J requires approximately 2535 to 2957.5 kcal/day after a total colectomy based on his ideal body weight of 84.5 kg and the stress of surgery. None of the provided options meet his estimated caloric needs.
Step-by-step explanation:
To determine the daily caloric needs of Mr. J. after a total colectomy, we need to consider his ideal body weight (IBW) and the stress factor associated with major surgery. The IBW for Mr. J is given as 84.5 kg. A general estimation for caloric needs post-surgery is 30-35 kcal/kg/day for a person with IBW, considering the increased energy requirements for healing and recovery.
Calculating Mr. J's caloric needs at a lower end estimation (30 kcal/kg/day):
84.5 kg x 30 kcal/kg/day = 2535 kcal/day
At the higher end (35 kcal/kg/day):
84.5 kg x 35 kcal/kg/day = 2957.5 kcal/day
So, Mr. J requires approximately 2535 to 2957.5 kcal per day. Therefore, none of the provided options (a) 1700 kcal/day, (b) 1950 kcal/day, (c) 2200 kcal/day, or (d) 2450 kcal/day, are adequate for his post-surgery needs. His caloric needs are higher than the highest option given.
