Deck 35: Medical Nutrition Therapy for Pulmonary Disease

Question 1

What is the effect of pulmonary disease on a patient's energy requirements?

A)Decreased need for energy because of loss of lean body mass
B)Increased need for energy because of increased work of breathing
C)Decreased need for energy because of a lack of physical activity
D)Decreased need for energy because of starvation

Answer 1

B
Pulmonary disease promotes an increase in energy requirements caused by increased muscular work to promote breathing, possible chronic infection, and medical treatments.Malnutrition in relation to pulmonary disease can contribute to a loss of lean body mass and decreased capacity to perform physical activity.Additionally, malnutrition could impair immune function and contribute to the likelihood of infection.

Question 2

Which of the following explains why nutritional wasting is commonly seen in patients with COPD?

A)Increased energy expenditure, decreased energy intake, and impaired oxygenation
B)Decreased oxygen consumption and increased energy expenditure
C)Decreased energy expenditure and decreased oxygen consumption
D)Increased oxygen consumption and increased energy intake

Answer 2

A
Patients with COPD may experience nutritional wasting because of a combination of factors.Increased energy expenditure occurs because of the increased work undertaken by the respiratory system to breathe.This increase results from the obstruction of airflow.On the other side of the cause is decreased food intake.This is brought on by fatigue and confusion caused by lack of oxygen and the buildup of carbon dioxide in the blood.

Question 3

Which of the following is TRUE regarding pancreatic enzyme replacement therapy?

A)It is needed to treat all patients with CF.
B)It is needed to treat CF patients with malabsorption.
C)It is provided in approximately the same dosages for all CF patients.
D)It is not used to treat CF patients.

Answer 3

B
About 85% to 90% of patients with cystic fibrosis have pancreatic insufficiency.When this occurs, mucus plugs reduce pancreatic enzyme secretion into the small intestine, and maldigestion and malabsorption result.A fecal fat test usually is necessary to determine if fat malabsorption is occurring.After this has been determined, then pancreatic enzyme replacement therapy may be used as part of the nutritional care.

Question 4

Which of the following recommendations should be made to the parents of an infant who has both BPD and esophageal reflux?

A)Cor pulmonale
B)Emphysema

D)Acute respiratory distress syndrome

Question 8

What is the recommendation for determining energy needs for patients with COPD?

A)Provide 30 to 35 kcal/ kg of body weight.
B)Provide 130% to 150% of the BEE.

D)Provide the EER.

A)It is a pulmonary function test.
B)It gives information on lung volume.
