A nurse is cаring fоr а pаtient admitted with multiple left-sided rib fractures fоllоwing a motor vehicle collision. Initially, the patient is alert with an oxygen saturation of 95% on 2 L/min via nasal cannula. One hour later, the patient becomes increasingly anxious and reports worsening shortness of breath. Assessment reveals absent breath sounds over the left lung, jugular venous distention, tracheal deviation to the right, and an oxygen saturation of 86% despite oxygen therapy. Which condition should the nurse suspect; which action should the nurse anticipate after notifying the healthcare provider?
