Question

The basal energy rate is the daily amount of energy (measured in calories) needed by the body at rest to maintain body temperature and the basic life processes of respiration, cell metabolism, circulation, and glandular activity. As you may suspect, the basal energy rate differs for individuals, depending on their gender, age, height, and weight. The formula for the basal energy rate for men is

where B is the basal energy rate (in calories), W is the weight (in kilograms), H is the height (in centimeters), and A is the age (in years).

A male patient is 70 years old, wieghs 55 kilograms, and is 172 centimeters tall. A total daily caloric intake of 1000 calories is prescribed for him. Determine if his caloric intake is sufficient for his needs and explain why or why not.
a.
1000 calories is too much; it is 172 calories past the needed amount.
b.
1000 calories is not sufficient; it is 172 calories short.
c.
1000 calories is not sufficient; it is 310 calories short.
d.
1000 calories is too much; it is 310 calories past the needed amount.

Answer 2

B = 655.096 + 9.563W + 1.85H - 4.676A
W = 55
A = 70
H = 172
now we sub
B = 655.096 + 9.563(55) + 1.85(172) - 4.676(70)
B = 655.096 + 525.965 + 318.2 - 327.32
B = 1499.261 - 327.32
B = 1171.941

1171.941 - 1000 = 171.941 rounds to 172
answer is B. 1000 calories is not sufficient, it is 172 calories short
