Your patient is a 55 year old male who was struck in the right side of the
chest with a piece of steel pipe. He presents with uncooperative
behavior, his skin is pale and moist, the ventilatory rate is 32, there is a
weak radial pulse of 112, and breath sounds are decreased on the right
side. The trachea is midline and jugular veins are flat while the patient is
supine. There is isolated crepitus over the 4th and 5th ribs in the
midaxillary line on the patient's right side. Based on the mechanism of
injury and the assessment findings, which of the following is the most
likely cause of the patient's signs and symptoms?

B. Simple pneumothorax
C. Pulmonary contusion
D. Hemothorax - CORRECT ANSWER-D. Hemothorax
