Mrs. T, a 58-year-old house wife, tells the clinic nurse that she does not understand why she does not lose weight since she is very active. Although she does not walk outside, she is busy most of the day doing housework, cooking, and doing laundry.
 
  She does not watch television until all of her housework is completed for the day. The best response for the nurse would be: 1. Doing housework uses the same amount of kcalories/min as swimming, so it is a good way to lose weight..
   2.  Doing housework only utilizes about 3 kcalorie/min compared with 6.1 kcalories/min walking..
   3. In order to lose weight you must increase physical exercise and reduce calories..
   4. As people age they tend to naturally gain weight..

Question 2

The nurse is teaching a nutrition class on how to estimate the total number of calories expended by a person per day according to the rule-of-thumb formula.

Answer to Question 1

3
Rationale: The best way to lose weight is to create negative energy expenditure by reducing calories consumed and increasing physical activity. Housework uses about one-third of the calories/min as swimming uses. Moderate to vigorous activity is needed to promote weight loss. Weight gain in older adults is usually related to a decrease in physical activity.

Answer to Question 2

B
Feedback:
First, calculate the BMR: For men, multiply the weight by 11 (160  11 = 1760); next, calculate the estimated total calories based on the activity level (sedentary activity level is indicated at 20) (1760  0.20 = 352). Add the BMR calories and PA calories to determine the total calories for the day: 1760 + 352 = 2112 calories.
