What are three functions of gas exchange? -
Correct Answers-
maintains homeostasis by feedback mechanisms
carbon dioxide, oxygen and hydrogen ion
concentrations determine the rate of respiration by
acting directly on the respiratory center of the brain
directs the contraction and relaxation of respiratory
muscles
What is the primary function of the pulmonary system? -
Correct Answers-
gas exchange
Define alveoli. -
Correct Answers-
function for gas exchange between air and blood
Define surfactant. -
Correct Answers-
A lipoprotein that coats the alveoli to reduce surface
tension and prevent alveolar collapse
Name the obstructive lung diseases. -
Correct Answers-
asthma
cystic fibrosis (CF)
chronic obstructive pulmonary disease (COPD)
1
,emphysema
chronic bronchitis
Define asthma. -
Correct Answers-
chronic inflammatory disorder of the airways leading to
recurrent but reversible episodes of airway obstruction
What are s/s of asthma? -
Correct Answers-
coughing, chest tightness, wheezing, SOB
Define cystic fibrosis -
Correct Answers-
a genetic disorder that affects the lungs as well as the
pancreas, and at times other organs - it causes the
mucous to become thick and sticky, which clogs the
lungs and prevents the pancreas from producing
digestive enzymes
Define COPD. -
Correct Answers-
progressive, persistent airflow limitation that is
associated with a chronic inflammatory response in the
airways and lungs
Define emphysema. -
Correct Answers-
characterized by anatomical alterations including,
overinflated and broken alveolar sacs, bronchioles, and

2
,Define chronic bronchitis. -
Correct Answers-
characterized by excessive mucous secretion of the
bronchial tree
What are the factors for COPD? -
Correct Answers-
smoking, air pollution, occupational exposure, repeated
respiratory infections, hereditary, aging, allergies
How does hyperinflation of the lungs flattening the
diaphragm effect nutritional intake? -
Correct Answers-
it results in early satiety, belching, and bloating
What are the lung disease effects on nutritional intake?
-
Correct Answers-
impaired GI function
increased energy expenditure
swallowing difficulty
What makes swallowing difficulty regarding lung
diseases? -
Correct Answers-
the presence of hypoxemia as swallowing involves
holding breath
Why is energy expenditure increase in lung diseases? -
Correct Answers-
3
, increased work of breathing
ventilatory muscle inefficiency -- increased resistance,
decreased efficiency
depression
cigarette smoking
What is pulmonary cachexia syndrome? -
Correct Answers-
malnutrition associated with advanced lung disease
What are the contributing factors of pulmonary cachexia
syndrome? -
Correct Answers-
changes in metabolism and intake
inflammation
lack of exercise
medications
What are the energy and protein requirements for
chronic pulmonary patients? -
Correct Answers-
