You are transporting a stable patient with a possible pneumothorax. The patient is receiving high-flow oxygen and has an oxygen saturation of 95%. During your reassessment, you find that the patient is now confused, hypotensive, and profusely diaphoretic. What is most likely causing this patient's deterioration? A.

Bystanders who removed her state that she was not wearing a seatbelt. The patient is unresponsive, tachycardic, and diaphoretic. Your assessment reveals bilaterally clear and equal breath sounds, a midline trachea, and collapsed jugular veins. You should be most suspicious that this patient has experienced a: A. pericardial tamponade B. tension pneumothorax C. laceration of the aorta D. massive hemothorax

C. laceration of the aorta.

When a person is lying supine at the end of exhalation, the diaphragm: A. contracts and flattens inferiorly B. descends below the level of the navel C. might rise as high as the nipple line D. is less prone to penetrating trauma

If a person's tidal volume decreases, but his or her respiratory rate remains unchanged: A. minute volume will remain unchanged. B. minute volume will increase. C. minute volume will decrease. D. excess carbon dioxide will be eliminated.

C. minute volume will decrease.

A rapid, irregular pulse following blunt trauma to the chest is most suggestive of a: A. tension pneumothorax B. pericardial tamponade C. myocardial contusion D. ruptured aorta

Subcutaneous emphysema is an indication that: A. your patient is experiencing a pericardial tamponade B. at least half of one lung has completely collapsed C. blood is slowly accumulating within the tissue of the lung D. air is escaping into the chest wall from a damaged lung.

D. air is escaping into the chest wall from a damaged lung.

A flail chest occurs when: A. a segment of the chest wall is detached from the thoracic cage. B. multiple ribs are fractured on both sides of the thoracic cage. C. a segment of fractured ribs bulges during the inhalation phase. D. more than three ribs are fractured on the same side of the chest.

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

A 37-year-old male was pinned between a flatbed truck and a loading dock. On exam, you find bruising to the chest, distended neck veins, bilaterally diminished breath sounds, and bilateral scleral hemorrhaging. You should: A. aggressively manage his airway B. suspect a severe hemopneumothorax C. request a paramedic ambulance D. perform a secondary assessment

A. aggressively manage his airway.

An open pneumothorax is: A. an open chest wound through which air moves during breathing B. a fractured rib that perforates the tissue of the lung surface C. the entry of air into the pleural space from a perforated lung D. extreme pleural pressure that causes the lung to rupture

A. an open chest wound through which air moves during breathing.

Signs and symptoms of a tension pneumothorax include all of the following, except: A. collapsed jugular veins B. profound cyanosis C. unilaterally absent breath sounds D. altered mental status.

A. collapsed jugular veins.

Following a stab wound to the left anterior chest, a 25-year-old male presents with a decreased level of consciousness and signs of shock. Which of the following additional assessment findings should increase your index of suspicion for a cardiac tamponade? A. Widening pulse pressure B. Engorged jugular veins C. Diminished breath sounds D. A rapid, irregular pulse

B. Engorged jugular veins

The thoracic cavity is separated from the abdominal cavity by the: A. anterior rib cage B. diaphragm C. intercostal margin D. costovertebral angle

B. diaphragm.

If a patient with a chest injury only inhales small amounts of air per breath, he or she: A. often breathes at a slower rate because of lung damage caused by the injury. B. must increase his or her respiratory rate to maintain adequate minute volume. C. will eliminate more carbon dioxide than if he or she were breathing deeply. D. will maintain adequate minute volume if his or her respiratory rate stays the same.

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

Irritation or damage to the pleural surfaces that causes sharp chest pain during inhalation is called: A. pneumonitis B. pleurisy C. dyspnea D. pneumothorax
