16. Mr. Katz, who is 48 years old, is admitted to the hospital with a fracture to his left hip. He weighs 248 lb (54 lb above his desired weight). He is considered to be in a state of overnutrition. The statement most true regarding his state of overnutrition is that a. desired nutrients are consumed in excess amounts without the risk of malnutrition. b. because excess body fat is evident and excess calories are consumed, there is no risk of nutrient deficiency leading to malnutrition. c. even though excess body fat and excess nutrient intake are evident, there still may be a risk for some type of nutrient deficiency leading to malnutrition. d. excess body weight may or may not be present along with excess consumption of carbohydrates and fat, which results in inadequate vitamin and mineral intake.

ANS: C Overnutrition results from excess nutrient and energy intake over time, resulting in excess weight and a state of obesity. Malnutrition can result from excess body weight and the lack of vitamin- and mineral-rich food consumption (e.g., consumption of fatty and carbohydrate-rich foods only).
