## 문제

A nurse is caring for a patient with a penetrating chest wound. Which nursing action should be the highest priority?

## 보기

1. Stabilize the impaled object and leave it in place **✔ 정답**
2. Remove the impaled object immediately to assess the wound
3. Apply direct pressure around the impaled object
4. Position the patient in high Fowler's position

**정답: 1**

## 해설

The highest priority is to stabilize the impaled object and leave it in place to prevent further tissue damage and hemorrhage. Removing it can cause life-threatening bleeding or air embolism.

Understanding the Priority: Why We Leave the Object in Place

The highest priority when managing a patient with a penetrating chest wound and an impaled object is to stabilize the impaled object and leave it in place. This is not merely a first-aid tip but a critical intervention grounded in the pathophysiology of tamponade and the mechanics of thoracic injury.

The core principle is that the impaled object itself may be acting as a partial plug. When a foreign body penetrates the chest wall, it can lacerate blood vessels and lung tissue. By remaining in situ, the object can exert direct mechanical pressure on the damaged tissues, thereby reducing hemorrhage and limiting air entry into the pleural space [1]. Removing the object prematurely removes this tamponade effect, which can instantly convert a controlled injury into a catastrophic, exsanguinating hemorrhage or a massive tension pneumothorax. The case report illustrates this clearly: the patient presented with a wooden fragment impaled in the left chest, and the initial management was explicitly centered on resuscitation and stabilization with the object in place before definitive surgical control [1].

Analyzing the Incorrect Options

- Option 2: Remove the impaled object immediately to assess the wound. This action is contraindicated and dangerous. Removal should only be performed in a controlled surgical environment where the surgical team is prepared to immediately repair the underlying vascular and pulmonary injuries. In the pre-hospital or emergency department setting, blind removal can lead to uncontrolled bleeding and respiratory collapse that is difficult to reverse [1].

- Option 3: Apply direct pressure around the impaled object. While controlling hemorrhage is a priority, applying direct pressure around an unstable object can inadvertently move it, worsening internal laceration or dislodging the tamponade effect. The priority is to first secure the object to prevent movement. After stabilization, a bulky dressing can be placed around the object to support it and help control external bleeding, but this is a secondary step to stabilization.

- Option 4: Position the patient in high Fowler's position. Positioning is an important consideration but is not the highest priority. A patient with a penetrating chest wound and a reported SpO₂ of 78% on room air is in respiratory distress [1]. While an upright position may facilitate breathing in some scenarios, the immediate life threat is the potential dislodgement of the object. The patient should be positioned for comfort and to minimize movement of the object, which may not always be high Fowler's. The first action must always be to secure the impaled object to prevent a rapid deterioration from hemorrhage or tension pneumothorax.

Clinical Application and Pathophysiology

The case of the 63-year-old male who fell from a tree provides a direct clinical correlation. He sustained an impalement at the 7th intercostal space with a wooden fragment, presenting with classic signs of a life-threatening chest injury: absent air entry, a sucking chest wound, tachycardia (104 bpm), tachypnea (32/min), and severe hypoxemia [1]. The initial management focused on resuscitation and stabilization, which inherently includes securing the foreign body. The physiological rationale is that the thoracic cavity relies on negative pressure for lung expansion. A penetrating object creates a direct communication between the atmospheric pressure and the pleural space. If the object is removed, this open defect can rapidly lead to a pneumothorax, and if a "ball-valve" effect occurs, a tension pneumothorax can develop, shifting the mediastinum and obstructing venous return to the heart. By stabilizing the object, the nurse minimizes the movement that could enlarge the wound tract, disrupt a forming clot, or break the partial seal that is limiting the pneumothorax. This action directly addresses the immediate threats of hemorrhagic shock and respiratory failure, which are the leading causes of death in thoracic trauma [1].References (research sources)

## 임상 시나리오

Managing an Impaled Object in the ChestPreserve the Tamponade Effect to Prevent Catastrophic Decompensation
The highest priority is to stabilize the impaled object and leave it in place. The object acts as a partial plug, providing a tamponade effect that limits hemorrhage and air entry into the pleural space.

Stabilization is achieved by using bulky dressings or tape to secure the object without applying pressure that could push it deeper. Manual stabilization must be maintained during patient transport and positioning.

CautionNever remove an impaled chest object in the prehospital or emergency department setting. Removal is performed only in a controlled surgical environment with a team prepared for immediate thoracotomy and vascular repair. Premature removal can instantly convert a controlled injury into an exsanguinating hemorrhage or a tension pneumothorax.

## 핵심 개념

- **Tamponade Effect** — The mechanism by which an impaled object exerts direct pressure on damaged tissues and vessels, reducing hemorrhage and air entry into the pleural space by acting as a partial plug.
- **Tension Pneumothorax** — A life-threatening condition where air enters the pleural space and cannot escape, causing lung collapse, mediastinal shift, and compression of the heart and great vessels.
- **Penetrating Chest Wound** — An injury caused by a foreign object piercing the chest wall, potentially damaging the lungs, heart, and major blood vessels, creating an open pneumothorax.
- **Exsanguinating Hemorrhage** — Extremely severe, life-threatening bleeding that can lead to rapid blood loss, hypovolemic shock, and death if not immediately controlled.
