Answer to Question 1
Correct Answer: 3
Primary pneumothorax affects previously healthy people, usually tall, slender men between ages 16 and 24. The cause of primary pneumothorax is unknown. Risk factors include smoking. Certain activities also increase the risk of spontaneous pneumothorax, such as high-altitude flying and rapid decompression during scuba diving. The patient's age, smoking status, and scuba diving interest do not increase the risk for developing a pleural effusion, pleurisy, or a hemothorax.
Answer to Question 2
Correct Answer: 1
Physiologic function of the chest wall is impaired as the flail segment is sucked inward during inhalation and moves outward with exhalation. This is known as paradoxic movement. This movement is not associated with pleurisy, pneumothorax, or pneumonia.
