,1. What is the primary physiological function of Type II
pneumocytes?
a) Gas exchange
b) Production of surfactant
c) Blood-air barrier maintenance
d) Removal of foreign particles
Correct Answer: b) Production of surfactant
Rationale: Type II pneumocytes are responsible for the
production and secretion of pulmonary surfactant which decreases
surface tension within the alveoli and prevents alveolar collapse.
2. Which of the following is a common cause of secondary
spontaneous pneumothorax?
a) Asthma
b) Chronic obstructive pulmonary disease (COPD)
c) Cystic fibrosis
d) All of the above
, Rationale: Secondary spontaneous pneumothorax can occur due
to underlying lung diseases such as asthma, COPD, and cystic
fibrosis, which can lead to the development of blebs that rupture.

which class of medication is primarily used to target the
endothelin pathway?
a) Beta-blockers
b) Calcium channel blockers
c) Phosphodiesterase inhibitors
d) Endothelin receptor antagonists
Correct Answer: d) Endothelin receptor antagonists
Rationale: Endothelin receptor antagonists, such as bosentan,
are used in the treatment of PAH to block the effects of
endothelin-1, thereby reducing pulmonary vascular resistance.
, Correct Answer: c) Bronchogenic carcinoma
Rationale: The patient's history and radiographic findings are
