Explanation

Pneumothorax involves air accumulating in the pleural space, which causes the lung on the affected side (the right side in this case) to partially or fully collapse.
A collapsed lung cannot participate in ventilation (air exchange).
This lack of airflow results in the absence of audible breath sounds during auscultation over the affected area, making it a hallmark diagnostic sign of pneumothorax.

Option B: Stridor is a high-pitched, harsh sound heard during inspiration or expiration, caused by turbulent airflow in a narrowed upper airway (like the larynx or trachea). It is not associated with problems in the pleural space.
Option C: Tachycardia (a heart rate over 100 bpm) is a non-specific sign of physiological stress. While a patient with a pneumothorax may be tachycardic due to pain, anxiety, or hypoxia, it is not a definitive sign because countless other conditions also cause tachycardia.
Option D: Hypertension (high blood pressure) is not a characteristic sign of pneumothorax. In fact, a large or tension pneumothorax can compress the heart and great vessels, impairing venous return and leading to decreased cardiac output and severe hypotension (low blood pressure).

Clinical Relevance

Nursing practice connection: Use the key finding related to Clinical assessment and diagnosis of pneumothorax to guide bedside assessment, documentation, and the next nursing action.
A unilateral absence of breath sounds is a critical assessment finding that requires immediate reporting and intervention, as it strongly suggests a pneumothorax.
Nurses must be able to rapidly differentiate between a simple pneumothorax and a tension pneumothorax, which is a medical emergency characterized by tracheal deviation, severe hypotension, and distended neck veins.
What if? If the patient also developed tracheal deviation to the left and severe hypotension, the condition has likely progressed to a tension pneumothorax. This requires immediate needle decompression by a trained provider, not just preparation for a standard chest tube.

How to Approach the Question

First, understand the pathophysiology of the condition in the stem: A pneumothorax is air in the pleural space that causes the lung to collapse.
Next, analyze each option based on this pathophysiology. Ask yourself, 'What would be the direct result of a lung collapsing on one side?'
Consider the flow of air. A collapsed lung cannot be ventilated. Therefore, you would not hear the sound of air moving in and out.
Evaluate the other options for specificity. Stridor is an upper airway sound. Tachycardia is a general sign of distress. Hypertension is the opposite of what is expected in severe cases (hypotension is more likely).
Select the option that is the most direct and specific consequence of the underlying problem. Absent breath sounds directly correlate with a non-ventilated, collapsed lung.
