Answer 8

8.  Choice C is the correct answer.  This patient has over a 15 percent pneumothorax on the left side.  So observation is not appropriate.  This pneumothorax does not appear to have any blood so a 28 or 32 french is appropriate.  If there is a hemothorax a 36 or 40 French would be appropriate so it can drain effectively.  This finding on the left side is not a pneumonia or mass.  There is missing lung markings consistent with a pneumothorax.
