QuestionSBA
QuestionChoice
This is correct. Pulmonary fibrosis is a lung disease characterized by the formation of scar tissue within the lung parenchyma. This scar tissue makes the lungs stiff and less compliant.

a
Decreased lung compliance is associated with conditions like pulmonary fibrosis
QuestionChoice
This is incorrect. Decreased lung compliance can lead to impaired gas exchange due to reduced lung expansion and difficulty in ventilating the alveoli effectively.
10026107
c
Decreased lung compliance improves the efficiency of gas exchange in the alveoli
QuestionChoice
This is incorrect. Decreased lung compliance is primarily caused by factors that reduce lung elasticity, such as pulmonary fibrosis or scarring of lung tissue. Increased lung elasticity would typically lead to increased lung compliance, making it easier to expand the lungs during inhalation.

e
Decreased lung compliance is primarily caused by increased lung elasticity
QuestionChoice
This is incorrect. Decreased lung compliance results in increased work of breathing for the patient as more effort is required to expand the lungs and overcome the reduced compliance.
10026108
d
Decreased lung compliance results in reduced work of breathing for the patient
QuestionChoice
This is incorrect. Decreased lung compliance actually makes it harder for the lungs to expand during inhalation, which can lead to increased effort required for breathing.

b
Decreased lung compliance leads to easier expansion of the lungs during inhalation

A 60-year-old patient with a history of smoking and a recent diagnosis of pulmonary fibrosis presents to the emergency department. The patient is experiencing increasing difficulty breathing and is coughing frequently. The clinician suspects a decrease in lung compliance and requests a chest X-ray for evaluation.

Which of the following statements about lung compliance is correct?
a
