Aortic rupture

A flail chest occurs when:

a segment of the chest wall is detached from the thoracic cage.

While jogging, a 19-year-old male experienced an acute onset of shortness of breath and pleuritic chest pain. He is conscious and alert with stable vital signs. Your assessment reveals that he has diminished breath sounds over the left side of the chest. You should:

administer oxygen and transport to the hospital.

An open pneumothorax occurs when:

air enters the pleural space from outside the body.

Closed chest injuries are typically caused by _______.

laceration of the aorta.

If a patient with a chest injury is only able to inhale small amounts of air per breath, he or she:

must increase his or her respiratory rate to maintain adequate minute volume.

A spinal cord injury at the level of C7 would MOST likely result in:

paralysis of the intercostal muscles

In order to avoid exacerbating a patient's injury, it is especially important to use extreme caution when providing positive-pressure ventilation to patients with a

pneumothorax.

A 28-year-old male was struck in the chest with a baseball bat during an altercation. He is conscious and alert and complains of severe chest pain.

A man called EMS 12 hours after injuring his chest. Your assessment reveals a flail segment to the right side of the chest.
