Answer to Question 1

Ans:
D

Feedback:

Adenocarcinoma is associated with the periphery of the lungs, often at the site of scarring, and can occur in alveolar or bronchiolar tissue. Squamous cell carcinoma, small cell lung cancer, and large cell carcinoma are less commonly associated with these traits.

Answer to Question 2

Ans:
D

Feedback:

Regional hypoxia, such as with a diagnosis of atelectasis, is associated with vasoconstriction and redirection of blood away from, not toward, the affected area of the lung. This also contributes to an increased workload for the right side of the heart.
