Answer to Question 1

He is 29.5 overweight which classifies him as obese. Depending on how you teach the problem of obesity, you may or may not want to do an adjusted body weight. If this calculation is not desired, simply use his real body weight instead of his adjusted body weight in the calculations that follow.

Adjusted body weight = (actual body weight - IBW) x .25 + IBW
= (215 - 166) x .25 + 166
= 49 x .25 +166
= 12.25 + 166 = 178 lbs

BEE = 66 + 13.7 x80.9 + 5 x 177.8 - 6.8 x 45
= 66+ 1338.5 + 889 - 306
= 1757.3

1987 x activity factor = total caloric needs/day

For activity factor, use sedentary = 1757 x 30 = 1757 + 527 = 2284 kcals

Answer to Question 2

First of all, the smoking habit for 40 years brought on the pulmonary problem that resulted in her inability to be as active as she once could be. Depression has brought about more inactivity, anorexia, difficulty sleeping, and more medications to produce side effects. The stress probably stimulated HCl secretion which irritated her gastritis and contributed to her anorexia. This all leads to improper intake of food, malnutrition, and a decrease in lymphocytes and MCV.
