Review Question - QID 109714

A 17-year-old boy is brought to the emergency department by his parents 6 hours after he suddenly began to experience dyspnea and pleuritic chest pain at home. He has a remote history of asthma in childhood but has not required any treatment since the age of four. His temperature is 98.4°F (36.9°C), blood pressure is 100/76 mmHg, pulse is 125/min, respirations are 24/min. On exam, he has decreased lung sounds and hyperresonance in the left upper lung field. A chest radiograph shows a slight tracheal shift to the right. What is the best next step in management?
