How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is the key distinguishing feature of a tension pneumothorax compared with a simple pneumothorax?

Answer: Progressive intrathoracic pressure causing obstructive shock. In tension pneumothorax, air accumulates under pressure, compressing mediastinal structures and impeding venous return, unlike simple pneumothorax.

Flashcard 2: Identify the preferred AEMT treatment for a suspected tension pneumothorax with severe distress and shock.

Answer: Needle decompression. This procedure relieves intrathoracic pressure by allowing trapped air to escape, restoring hemodynamic stability in emergent cases.

Flashcard 3: Which lung injury involves alveolar bleeding and swelling causing hypoxia after blunt trauma?

Answer: Pulmonary contusion. Blunt force causes capillary damage, leading to edema and impaired gas exchange, progressively worsening oxygenation.

Flashcard 4: Which condition is defined as blood in the pleural space, usually from trauma?

Answer: Hemothorax. Blood accumulation compresses the lung, impairs gas exchange, and can lead to hypovolemic shock if massive.

Flashcard 5: Which injury is defined as blood in the pericardial sac causing impaired cardiac filling?

Answer: Cardiac tamponade. Pericardial blood restricts diastolic filling, reducing stroke volume and cardiac output, leading to shock.

Flashcard 6: Identify the pathophysiologic shock type most associated with tension pneumothorax and tamponade.

Answer: Obstructive shock. These conditions mechanically obstruct venous return or cardiac output, leading to inadequate perfusion despite normal blood volume.

Flashcard 7: Identify the most reliable early sign of significant internal abdominal bleeding in trauma.

Answer: Unexplained tachycardia with signs of shock. Tachycardia compensates for hypovolemia early, often preceding hypotension in internal hemorrhage detection.

Flashcard 8: Which classic triad is associated with cardiac tamponade (Beck triad)?

Answer: Hypotension, JVD, muffled heart sounds. Beck's triad reflects impaired cardiac filling from pericardial pressure, with elevated venous pressure and diminished cardiac sounds.

Flashcard 9: What is the recommended adult needle decompression site: anterior axillary line at which intercostal space?

Answer: Fourth or fifth intercostal space, anterior axillary line. This alternative site reduces the risk of vascular injury while effectively accessing the pleural cavity for pressure relief.

Flashcard 10: Which abdominal organ is most commonly injured in penetrating abdominal trauma?

Answer: Small intestine. Its extensive length and intraperitoneal location increase exposure to penetrating projectiles or blades.

Flashcard 11: What is the most appropriate oxygenation strategy for pulmonary contusion with worsening hypoxia?

Answer: Supplemental oxygen; assist ventilations if inadequate. This approach maintains oxygenation while supporting ventilation to counteract progressive hypoxia from alveolar damage.

Flashcard 12: Which finding best identifies an open pneumothorax (sucking chest wound)?

Answer: Open chest wall defect with air movement and bubbling. The defect allows air to enter during inspiration, producing audible sucking sounds and visible bubbling from blood-air mixture.

Flashcard 13: Which action is contraindicated when managing abdominal evisceration in the field?

Answer: Do not attempt to replace organs into the abdomen. Replacing organs risks infection, further injury, or vascular compromise, so they should remain external and covered.

Flashcard 14: Identify the correct patient position for abdominal injury with suspected shock when not contraindicated.

Answer: Supine position. Supine positioning optimizes venous return and perfusion in shock states without spinal contraindications.

Flashcard 15: Which transport decision is most appropriate for unstable chest or abdominal trauma with suspected internal bleeding?

Answer: Rapid transport to a trauma center with minimal scene time. Unstable patients require prompt surgical intervention, so minimizing delays improves outcomes in hemorrhagic trauma.

Flashcard 16: What is the primary AEMT management for flail chest with respiratory compromise?

Answer: Positive-pressure ventilation with oxygen as needed. It stabilizes the flail segment and improves oxygenation by overcoming paradoxical motion and underlying pulmonary injury.

Flashcard 17: Which injury is defined as air in the pleural space causing partial or complete lung collapse?

Answer: Pneumothorax. This condition disrupts the negative intrapleural pressure, allowing atmospheric air to enter and collapse the lung tissue.

Flashcard 18: What is the recommended adult needle decompression site: midclavicular line at which intercostal space?

Answer: Second intercostal space, midclavicular line. This site is preferred for its accessibility and proximity to the pleural space apex, minimizing risks during decompression.

Flashcard 19: What is the most appropriate AEMT management priority for suspected massive hemothorax?

Answer: High-flow oxygen and rapid transport for definitive care. Prioritizing oxygenation supports respiratory function while expediting surgical intervention for hemorrhage control.

Flashcard 20: Which clinical finding is most characteristic of a tension pneumothorax in a deteriorating trauma patient?

Answer: Severe respiratory distress with hypotension. The building intrathoracic pressure shifts the mediastinum, reducing cardiac output and causing hypotension alongside impaired ventilation.

Flashcard 21: Which abdominal organ is most commonly injured in blunt abdominal trauma?

Answer: Spleen. The spleen's vascularity and left upper quadrant position make it vulnerable to deceleration forces in blunt impacts.

Flashcard 22: Identify the immediate action if an occlusive dressing on a chest wound worsens respiratory distress.

Answer: Lift or vent the dressing to release trapped air. Venting prevents pressure buildup that could convert the injury into a tension pneumothorax, alleviating worsening symptoms.

Flashcard 23: What is the preferred prehospital management for evisceration (exposed abdominal organs)?

Answer: Cover with moist sterile dressing, then occlusive cover. Moist coverage prevents desiccation of organs, while occlusion minimizes contamination and fluid loss.

Flashcard 24: What is the correct initial dressing for an open pneumothorax in the prehospital setting?

Answer: Vented chest seal (or occlusive dressing per protocol). It prevents air entry while allowing potential trapped air to escape, reducing the risk of developing tension pneumothorax.

Flashcard 25: Which injury is defined as paradoxical chest wall movement from multiple rib fractures?

Answer: Flail chest. Segmental rib fractures create an unstable chest wall section that moves oppositely during respiration, impairing ventilation.
