Questions: The nurse expect which assessment finding in a patient with a pneumothorax? Tracheal deviation toward the affected side Inability to auscultate tracheal breath sounds Pleuritic pain that worsens on inspiration Pursed-lip breathing

The answer is the third one: Pleuritic pain that worsens on inspiration.

Explanation for each option:

1. Tracheal deviation toward the affected side: This is incorrect. In the case of a pneumothorax, the trachea typically deviates away from the affected side due to the pressure buildup in the pleural space.
2. Inability to auscultate tracheal breath sounds: This is incorrect. While breath sounds may be diminished or absent on the affected side, tracheal breath sounds are usually still present.
3. Pleuritic pain that worsens on inspiration: This is correct. Pleuritic pain, which is sharp and worsens with inspiration, is a common symptom of a pneumothorax.
4. Pursed-lip breathing: This is incorrect. Pursed-lip breathing is more commonly associated with chronic obstructive pulmonary disease (COPD) rather than pneumothorax.

Summary: In a patient with a pneumothorax, the nurse would expect to find pleuritic pain that worsens on inspiration.
