Question

the nurse educator is explaining the pathophysiology of empyema to a group of nursing students. which of the following best defines an empyema? a collection of purulent fluid within the pleural space a viral infection of the pleural lining an accumulation of serous fluid in the pleural space a build - up of air in the pleural space causing lung collapse

Explanation:

To determine the correct definition of empyema, we analyze each option:

• Option 1: Empyema is defined as a collection of purulent (pus - containing) fluid in the pleural space. This matches the medical definition.
• Option 2: Empyema is not a viral infection of the pleural lining. It is related to purulent fluid accumulation, so this is incorrect.
• Option 3: An accumulation of serous fluid in the pleural space is called a pleural effusion (specifically a transudate or exudate of serous fluid), not empyema. So this is incorrect.
• Option 4: A build - up of air in the pleural space causing lung collapse is a pneumothorax, not empyema. So this is incorrect.

Answer:

A. a collection of purulent fluid within the pleural space
