✔✔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?
A. Tension pneumothorax
B. Simple pneumothorax
C. Pulmonary contusion
D. Hemothorax - ✔✔D. Hemothorax
✔✔Deterioration of ventilation and oxygenation after inflation of a PASG in a patient
who has sustained a high-pressure compression injury of the abdomen, such as a
sudden deceleration with the lap belt placed across the abdomen, most likely
represents which of the following injuries?
A. Abdominal aortic aneurysm
B. Ruptured diaphragm
C. Ruptured esophagus
D. "Paper bag" syndrome of the lungs - ✔✔B. Ruptured diaphragm
✔✔Which of the following is NOT a component of the Fick Principle?
