Answer :
The daily caloric need for a 72-year-old patient weighing 165 lbs (74.8 kg) would be approximately 1,870 kcal.
To calculate the daily caloric need, we'll use the given formula of 25 kcal/kg/day and apply it to the patient's weight.
1. Convert weight to kilograms:
Given weight is 165 lbs. To convert it to kilograms, divide by 2.2046: 165 lbs / 2.2046 = 74.8 kg.
2. Calculate the daily caloric need:
Multiply the weight in kilograms by the given factor of 25 kcal/kg/day: 74.8 kg * 25 kcal/kg/day = 1,870 kcal.
3. Round to the nearest whole number:
Since the question asks for the answer to be rounded to the nearest whole number, the final result is 1,870 kcal.
By following these steps, we can determine the daily caloric need in kilocalories (kcals) for the given patient based on their weight and the provided formula.
