First Aid for Corrections Officers Practice Test

What characterizes a sucking chest injury?

1. An injury involving a puncture wound

2. An open chest injury with a large hole

3. A condition associated with difficulty breathing

4. A bruise formed on the chest wall

The correct answer is: An open chest injury with a large hole

A sucking chest injury is characterized by an open chest wound that creates a direct passage between the outside environment and the pleural space. This injury typically involves a large hole, which can be caused by a penetrating object, like a stab wound or gunshot. The presence of this large hole allows air to enter the chest cavity during inhalation, leading to a build-up of pressure and potentially collapsing the lung on the affected side. The implications of this type of injury are critical, as it can severely impact the ability to breathe due to the disrupted pressure balance in the thoracic cavity. Additionally, the abnormal movement of air in and out of the chest cavity can lead to respiratory distress and inadequate oxygenation of the body. Understanding the nature of the injury helps first responders provide appropriate care, such as sealing the wound to prevent further air entry and stabilizing the patient's condition until advanced medical treatment can be received. Other options may describe aspects of chest injuries but do not specifically capture the defining feature of a sucking chest injury. For instance, while a puncture wound is relevant, it does not encompass the specific issues related to airflow and pressure imbalance that a sucking chest injury presents. Similarly, while difficulty breathing is a consequence of such an injury, it is not
