Answer :
Mark's new BMR with a fever of 99.6°F is approximately 2,464 calories, as fevers increase the BMR due to the increased rate of metabolic reactions.
Mark has a Basal Metabolic Rate (BMR) of 2,200 calories. With a fever of 99.6°F, which is above the normal body temperature, his BMR will increase. To calculate his new BMR, we need to convert his temperature to Celsius and then use the information that a fever increases BMR by about 14-15% per degree centigrade. The normal body temperature in Fahrenheit is 98.6°F, and in Celsius it is approximately 37°C. Mark's fever is 99.6°F which is 37.6°C (99.6 - 32) \/ 1.8. The difference between his fever temperature and the normal body temperature is 0.6°C. Assuming that his BMR will increase by approximately 10% for each 0.5°C increase (which is 7% from the provided information rounded to a simple number, 10%), his new BMR would be 2,200 calories + (10% of 2,200 calories for the additional 0.5°C) + (2% of 2,200 calories for the remaining 0.1°C), giving us a total increase of around 12%. Thus, Mark's new BMR would be approximately 2,200 + (0.12 \/ 2,200) which is 2,200 + 264 = 2,464 calories.
With a fever of 99.6ºF, Mark's adjusted BMR would be around 2,354 calories, increased by approximately 7%.
To calculate Mark's BMR (Basal Metabolic Rate) considering his fever, we can use the Harris-Benedict equation, which takes into account weight, height, age, and sex. However, since we're given only his BMR without these additional parameters, we'll need to make an estimation based on his temperature.
Research suggests that for every degree Fahrenheit increase in body temperature, the BMR increases by about 7%. Conversely, for every degree Fahrenheit decrease in body temperature, the BMR decreases by about 7%.
Given that Mark's temperature is 99.6ºF and normal body temperature is around 98.6ºF, his temperature increased by 1ºF.
So, to adjust Mark's BMR due to the fever, we'll increase it by 7%:
New BMR = Original BMR + (Original BMR * 0.07)
Substituting Mark's original BMR:
New BMR = 2200 + (2200 * 0.07)
New BMR ≈ 2200 + 154
New BMR ≈ 2354 calories
