Which sign is associated with an early tension pneumothorax?

• A. Rapid heartbeat
• B. Normal breathing
• C. Coughing
• D. Rapid and shallow breathing

Answer: (D)

Early tension pneumothorax triggers a stressed breathing pattern as air under pressure collapses the affected lung and reduces chest compliance. The body responds by increasing the respiratory rate, but the breaths remain shallow because each breath has less volume. This rapid, shallow breathing reflects the immediate respiratory distress and impaired gas exchange occurring in the early stages. While a fast heart rate can occur from anxiety or hypoxia, it isn’t as specific to the early respiratory compromise as the characteristic breathing pattern. Normal breathing wouldn’t indicate distress, and coughing is not the primary early sign of this condition.
