Answer to Question 1

Ans:
A

Feedback:

Atrial flutter is caused by a reentry rhythm that is located in the right atrium. It is normally responsive to pacing. His ECG will appear highly irregular, and the problem does not originate from sympathetic stimulation.

Answer to Question 2

Ans:
B

Feedback:

Atelectasis is characterized by incomplete lung expansion and can often be prevented by deep breathing and coughing. Pleural effusion, not atelectasis, is associated with fluid accumulation between the lungs and their lining, and neither chest tube insertion nor bronchodilators are common treatments for atelectasis.
