A nurse is caring for a patient with a penetrating chest wound from a stab injury who presents with sudden dyspnea and chest pain. Which nursing intervention should be the immediate priority?

## 보기

1. Remove the penetrating object immediately to prevent further tissue damage
2. Stabilize the penetrating object in place and avoid manipulation **✔ 정답**
3. Apply direct pressure around the wound to control bleeding
4. Position the patient in Trendelenburg position to improve circulation

**정답: 2**

## 해설

For a penetrating chest wound with an object in place, stabilizing the object is the priority to prevent further injury or bleeding. Other options like removal or repositioning can exacerbate the condition.

Understanding the Priority: Why Stabilization Comes First

For a patient with a penetrating chest wound, the immediate priority is always to stabilize the impaled object in place and avoid any manipulation. The clinical presentation of sudden dyspnea and chest pain following a stab injury strongly suggests a developing tension pneumothorax or major vascular injury. The impaled object itself may be acting as a partial plug, tamponading a lacerated vessel or limiting air entry into the pleural space. Removing it prematurely in an uncontrolled setting can dislodge a clot, converting a contained injury into a catastrophic, uncontrolled hemorrhage or a complete airway collapse.

Pathophysiological Rationale and Clinical Correlation

The penetrating object creates a direct tract through the chest wall, potentially involving the lung parenchyma, intercostal vessels, or great vessels. As noted in the literature on cervicothoracic impalement injuries, these traumas carry a high mortality risk due to the potential involvement of major vessels and airway structures [2]. The object’s position is a critical piece of the surgical puzzle. Manipulating or removing it alters the anatomical landscape and can trigger a sudden physiological decompensation. The primary goal of pre-surgical nursing and emergency management is to prevent secondary injury. This involves securing the object with bulky dressings to prevent movement during transport or patient repositioning, thereby maintaining the current, albeit critical, physiological equilibrium.

Analyzing the Incorrect Options

- Option 1 (Remove the penetrating object): This is the most dangerous action. Removal is strictly reserved for the controlled environment of an operating room, where a surgical team can immediately manage hemorrhage and repair complex pulmonary or vascular injuries [3]. The case series from Benin explicitly illustrates the complexity of managing these traumas surgically, underscoring why field removal is contraindicated [1].

- Option 3 (Apply direct pressure around the wound): While controlling external hemorrhage is a standard trauma principle, applying pressure around an impaled object in the chest is risky. The pressure can inadvertently move the object, worsening internal laceration, or push it deeper. The priority is stabilization, not external compression, which may not address the internal bleeding source and could exacerbate a tension pneumothorax.

- Option 4 (Position in Trendelenburg): This position is contraindicated in penetrating chest trauma. A head-down tilt will shift abdominal contents cephalad, further compromising diaphragmatic excursion and respiratory function in a patient already experiencing dyspnea with a respiratory rate that can be dangerously elevated [3]. It can also increase intrathoracic pressure, worsening the hemodynamic instability from a potential tension pneumothorax or cardiac tamponade. The patient requires a position of comfort, typically semi-Fowler's, to support ventilation.

Key NCLEX-RN Takeaway on Impalement Injuries

The management of an impaled object is a high-stakes, frequently tested concept. The core principle is to leave the object in situ and stabilize it. This is because the object serves as a direct marker of the injury tract and may be providing a life-saving tamponade effect. Your nursing intervention is to prepare for emergency surgical intervention, which includes securing the object, administering high-flow oxygen to address hypoxia (as seen with initial SpO₂ values improving from 78% to 90% with supplementation [3]), establishing large-bore IV access, and initiating rapid transport to a facility with thoracic surgical capability [1, 3].References (research sources)

## 임상 시나리오

Management of Impaled Objects in Chest TraumaStabilize, Don't Manipulate
The immediate priority is to stabilize the penetrating object in place using bulky dressings. The object may be tamponading a major vessel; removal can precipitate catastrophic hemorrhage or tension pneumothorax.

Secure the object to prevent movement during transport. Prepare for controlled surgical removal in the operating room. Do not apply pressure that pushes the object deeper.

CautionNever remove an impaled object in the prehospital or emergency department setting. Avoid Trendelenburg positioning, which increases intrathoracic pressure and worsens respiratory distress.

## 핵심 개념

- **Tamponade** — Compression of a vessel or organ by an object or accumulated fluid to stop bleeding or limit air entry.
- **Tension Pneumothorax** — A life-threatening condition where air enters the pleural space and cannot escape, collapsing the lung and shifting mediastinal structures.
- **Impaled Object** — A foreign body that penetrates and remains embedded in tissue, which should be stabilized in place until surgical removal.
- **Secondary Injury** — Additional harm caused after the initial trauma, often due to improper handling or movement of the patient or impaled object.
