Final answer:
The 18-year-old student likely requires an evaluation for a possible spontaneous pneumothorax, and long-term management could include lifestyle changes, medications, or surgery, depending on the exact diagnosis.
Step-by-step explanation:
A 18-year-old female college student experiencing sharp chest pain and shortness of breath (SOB) while playing tennis, with physical examination revealing tracheal shift to the left and absent breath sounds on the right, may be suggestive of a spontaneous pneumothorax or another acute chest condition. Long-term management will depend on the underlying diagnosis which can include lifestyle changes, medications, and possibly surgery. If it is a pneumothorax, treatment may include procedures to remove air from the pleural space and prevent future episodes like pleurodesis or surgery. It is important for the patient to have a thorough evaluation including imaging and consult with a healthcare professional, such as a pulmonologist or thoracic surgeon, for accurate diagnosis and management plan.
