A 19-year-old male experiences an acute onset of shortness of breath while jogging. His BP is 174/92, pulse 88, respirations 18, SpO2 90%. Diminished breath sounds are heard on the left. What is the appropriate action?

• A. Stop transport and observe
• B. Administer epinephrine
• C. Perform a needle decompression
• D. Administer oxygen and transport to the hospital

Answer: (D)

This scenario tests recognizing a likely spontaneous pneumothorax in a stable patient. The sudden shortness of breath with diminished breath sounds on one side and a低 oxygen saturation points to air in the pleural space causing partial lung collapse. In a patient who is still hemodynamically stable (blood pressure not dangerously low) and without signs of tension (no severe distress, no tracheal shift, no JVD), the immediate management is to provide supplemental oxygen to improve oxygenation and rapidly transport for definitive care, such as imaging and potential chest tube placement.

Needle decompression is reserved for a tension pneumothorax, where there are life-threatening signs of circulatory compromise; this patient doesn’t exhibit those signs. Administering epinephrine would not address a pneumothorax and is not indicated here. Stopping transport to observe would delay definitive treatment.

So, giving oxygen and transporting to the hospital is the best action.
