The nurse is caring for a client who sustained rib fractures after hitting the steering wheel of the car during a motor vehicle crash. The client is spontaneously breathing and receiving oxygen via a face mask; the oxygen saturation is 95%. During the nurse’s assessment, the oxygen saturation drops to 80%. The client’s blood pressure has dropped from 128/76 mm Hg to 84/60 mm Hg. The nurse assesses the breath sounds are absent throughout the left lung fields. The nurse notifies the provider and anticipates which order?
