A 28-year-old woman is brought to the trauma bay after a stab wound to the right anterior chest at the 4th intercostal space. On primary survey: GCS 15, airway patent, respiratory rate 24/min with equal bilateral air entry, BP 128/82 mmHg, HR 92/min. Examination of the wound shows a 2 cm laceration with minimal bleeding. There is no subcutaneous emphysema or tension pneumothorax. What is the most appropriate next step in management?
