The respiratory quotient may be decreased by increasing the proportion of energy intake from
 
  a. fat.
  b. protein.
  c. carbohydrates.
  d. fat and carbohydrates.

Question 2

Malnourished patients with chronic obstructive pulmonary disease (COPD) require protein intakes that are
 
  a. relatively low to reduce the metabolic burden.
  b. the same as healthy patients.
  c. relatively high to increase ventilatory drive.
  d. higher than can be met by oral intake.

Answer to Question 1

A
Respiratory quotient is lower when the proportion of energy intake from fat is higher. The respi-ratory quotient is the amount of carbon dioxide produced compared to the amount of oxygen used. Respiratory quotient is high for carbohydrate and low for fat.

Answer to Question 2

C
Malnourished patients with COPD have relatively high protein requirements to help increase ventilatory drive and preserve muscle mass. Low protein intakes will contribute to malnutrition. Protein needs are higher than for healthy patients, but can be achieved using a well-planned diet.
