Answer:
The correct answer to the question Which of the following indicates pleural effusion? would be: c) "I get a sharp, stabbing pain when I take a deep breath."
Step-by-step explanation:
Explanation: A pleural effusion is an unusual amount of fluid present in the pleural space (this pleural space is surrounded by the parietal and visceral pleurae). Parietal pleura envelops the inner surface of the chest cavity such as mediastinum, diaphragm, and ribs; on the other hand, visceral pleura engulf lung surfaces. The pleura is a thin layer of tissue that prevents friction between the wall of the thoracic cavity and the lungs each time you breathe. When these layers are swollen and inflamed rub towards each other, generating pain (pleurisy or pleuritic pain), every time your lungs expand as you take a breath. One of the symptoms is a sharp, stabbing pain (especially when breathing deeply).
