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?
- ANSWER-Hemothorax

deceleration with the lap belt placed across the abdomen, most likely represents which
of the following - ANSWER-Ruptured diaphragm
Which of the following is NOT a component of the Fick principle? - ANSWER-Adequate
number of platelets in the blood
