A client arrives at the emergency department with a penetrating ear injury from a metal object. Which nursing action should be the priority?

A 28-year-old construction worker presents to the emergency department after a metal fragment penetrated his left ear during a workplace accident. The fragment is still visible in the ear canal.

## 보기

1. Remove the foreign object immediately to prevent further damage
2. Irrigate the ear canal with normal saline to flush out debris
3. Leave the object in place and prepare for physician evaluation **✔ 정답**
4. Apply topical antibiotic drops to prevent infection

**정답: 3**

## 해설

For penetrating ear trauma with a retained foreign object, the priority is to leave it in place for physician evaluation to prevent further damage to delicate structures like the tympanic membrane or ossicles. Other options (removal, irrigation, antibiotics) risk worsening injury or infection.

Clinical Priority for Penetrating Ear Injury

The correct answer is Leave the object in place and prepare for physician evaluation. In the context of a penetrating injury where a metal fragment remains visible in the ear canal, the nurse's immediate priority is to stabilize the object and prevent any movement that could convert a localized injury into a catastrophic one.

Pathophysiology and Clinical Rationale

The external auditory canal is in close anatomical proximity to several critical structures, including the tympanic membrane, middle ear ossicles, facial nerve, and, deeply, the internal carotid artery and jugular bulb. A penetrating metal object may be tamponading a vascular injury or resting against a fragile structure. The case report by Hopper et al. highlights that penetrating trauma in this region can involve the intracranial carotid artery, a complication carrying a mortality rate approaching 20% even with operative management [1]. If the object is inadvertently removed or dislodged by irrigation, a contained vascular injury could be released, leading to uncontrolled hemorrhage, pseudoaneurysm formation, or air embolism. Similarly, the case of a sharp metallic foreign body in the bronchus described by Diop et al. reinforces the principle that sharp objects require meticulous, controlled removal under direct visualization, often with a combined anesthetic and surgical team approach, to avoid causing further tissue laceration during extraction [3].

Why Other Options Are Incorrect

- Option 1 (Remove the foreign object immediately): This is contraindicated. Blind removal in the emergency department without knowledge of the object's depth, orientation, or relationship to vascular structures can precipitate severe bleeding. The literature on foreign bodies notes that interpretation of their position and potential harm is critical before any intervention .

- Option 2 (Irrigate the ear canal): Irrigation is dangerous for penetrating injuries. The force of the fluid can dislodge a tamponading object, push it deeper, or cause movement that lacerates adjacent tissues. It is a standard contraindication when the integrity of the tympanic membrane is unknown or a penetrating object is present.

- Option 4 (Apply topical antibiotic drops): While infection prevention is a valid concern in trauma, it is not the priority nursing action. Applying drops before the object is stabilized and evaluated by a physician introduces fluid into a potentially open wound or fracture site, which could also dislodge debris or the object itself. The immediate priority is maintaining the status quo to prevent secondary injury, as emphasized in the observational study on trauma patterns where initial stabilization dictates subsequent outcomes .

Nursing Application

The nurse's role is to immobilize the object with a bulky dressing if possible, without applying direct pressure on the object itself, and to keep the patient calm and still. The head of the bed can be elevated to 30 degrees if not contraindicated by spinal precautions. Simultaneously, the nurse must prepare for an urgent otolaryngology or combined surgical consultation, as penetrating trauma with a retained foreign body in this anatomical location often requires operative exploration to rule out deep structure involvement, a principle clearly demonstrated in the successful combined neurosurgery and otolaryngology management of penetrating carotid trauma [1].References (research sources)

## 임상 시나리오

Penetrating Ear Injury: Initial ManagementStabilize the object to prevent catastrophic complications
For a visible penetrating object in the ear canal, the priority action is to leave the object in place and prepare for physician evaluation. The external auditory canal is adjacent to the internal carotid artery, jugular bulb, and facial nerve.

The object may be tamponading a vascular injury. Accidental removal or movement can release this pressure, leading to uncontrolled hemorrhage or air embolism. Mortality from vascular involvement approaches 20%.

CautionDo not irrigate the ear or attempt blind removal. Any manipulation risks converting a localized injury into a life-threatening event. Stabilize the object manually if necessary to prevent movement during transport.

## 핵심 개념

- **Tamponade** — A condition where a foreign object applies direct pressure on a ruptured blood vessel, preventing hemorrhage.
- **Penetrating Trauma** — An injury caused by an object piercing the skin and entering the body, creating an open wound with a high risk of deep structure damage.
