Which of the following is a symptom of pneumothorax?
Fever and chills
Dyspnea and decreased lung sounds
Persistent cough
Chest pain and vomiting
The correct answer is: Dyspnea and decreased lung sounds
The symptom of pneumothorax that indicates a significant presence of air in the pleural space is characterized by dyspnea, or difficulty breathing, and decreased lung sounds on the affected side. In a pneumothorax, air accumulation in the pleural cavity can lead to a collapse of the lung on the affected side, obstructing normal airflow and causing diminished breath sounds when assessed with a stethoscope. Additionally, the sensation of breathlessness (dyspnea) occurs due to the impaired lung function, making breathing labored or uncomfortable. This combination is a hallmark sign of pneumothorax and is crucial for diagnosis and subsequent management. The other symptoms listed, such as fever and chills, persistent cough, or chest pain and vomiting, may relate to other conditions or respiratory issues but are not the classic presentations of pneumothorax. Fever and chills typically suggest an infectious process rather than a pneumothorax. Meanwhile, a persistent cough often indicates conditions like bronchitis or pneumonia, and although chest pain can occur in pneumothorax, it is more associated with conditions like pleurisy or myocardial infarction when accompanied by vomiting. Understanding these distinctions is essential for effective assessment and nursing practice.
