question 4 (mandatory) (1 point)
listen
when taking a lateral decubitus chest x - ray, if you are evaluating for a pleural effusion, the involved side should be up.
true
false

Explanation:

• Question 3: The meniscus sign is a characteristic finding in pleural effusion. It is a curved or crescent - shaped opacity seen on chest radiographs that represents the fluid - air interface in the pleural space. Pleural plaques are related to asbestos exposure and are usually calcified, flat lesions. Mesothelioma is a tumor of the pleura. Silicosis is a lung disease caused by silica dust exposure with characteristic nodular opacities.
• Question 4: When taking a lateral decubitus chest x - ray to evaluate for a pleural effusion, the involved side should be down. This allows the fluid to layer out along the dependent pleural surface, making it easier to visualize small amounts of pleural effusion. If the involved side is up, the fluid may not layer out properly and can be missed.

Answer:

• Question 3: Pleural effusion
• Question 4: False
