Question

A patient that you are tending to cannot exceed 500 Cal per meal. You notice that on the label the meal has 21grams of fat, 68 grams of carbohydrates, and 40 grams of protein. On average fat has 9 Cal/g, carbohydrates have4 Cal/g, and protein has 4 Cal/g.a) How much energy would the patient consume if they would eat the whole meal?b) What is the unit symbol of the answer?c) Are they within the 500 Cal limit? Input Y for yes and N for no

Answer 1

To determine the total amount of calories consumed in that meal, we have to multiply the number of grams of each type of nutrient by the energy provided by each gram of that nutrient.

We are given that 1 gram of fat has 9 calories, therefore, 21 grams of fat have:

`9*21\text{ calories=189 calories}`

1 gram of carbohydrates gives 4 calories of energy, therefore, 68 grams have

`68*4\text{ calories= }272\text{ calories.}`

1 gram of protein has 4 calories, therefore, 40 grams of protein has:

`40*4\text{ calories=160 calories.}`

The mean has a total of:

`(189+272+160)\text{ calories=621 calories.}`

Answer:

A) 621 Cal.

B) Cal.

C) N.
