Explanation

Flail chest results from multiple rib fractures, causing a segment of the chest wall to move paradoxically, which severely impairs ventilation.
This paradoxical motion leads to inadequate gas exchange and hypoxemia (low blood oxygen), which is an immediate threat to life.
Therefore, the first-line management is to administer supplemental oxygen to correct the hypoxemia, following the ABCs (Airway, Breathing, Circulation) of trauma care.
Pain management is also a high priority to improve respiratory effort, but correcting oxygenation is the most immediate need.

Option A: Chest tube insertion is not the primary treatment for the flail segment itself. It is only performed if the patient has a concurrent pneumothorax (collapsed lung) or hemothorax (blood in the chest cavity), which are common associated injuries but not always present.
Option B: Intermittent Positive Pressure Ventilation (IPPV) is a form of mechanical ventilation. It is considered a secondary intervention, used only if the patient develops respiratory failure, fatigue, or severe hypoxemia that does not improve with supplemental oxygen and pain management.
Option C: Surgical repair of rib fractures is a definitive treatment, not an initial emergency intervention. It is reserved for a small subset of patients with severe deformity, chronic pain, or who cannot be weaned from mechanical ventilation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain First-line management of flail chest as background academic context rather than a clinical decision trigger.
In any trauma patient with chest injury, the nurse's immediate priority is to assess airway and breathing and apply oxygen. Flail chest is a classic life-threatening 'B' problem.
Effective pain management is crucial. Inadequate pain control leads to shallow breathing, retained secretions, atelectasis, and pneumonia. Nurses must advocate for and administer analgesia as prescribed.
Nurses must continuously monitor respiratory rate, oxygen saturation (SpO2), work of breathing, and mental status to detect respiratory fatigue early. A deteriorating patient may need urgent escalation to mechanical ventilation.

How to Approach the Question

First, identify the core clinical problem: 'flail chest'.
Recall the pathophysiology of flail chest: multiple rib fractures leading to an unstable chest wall segment, paradoxical breathing, and impaired gas exchange (hypoxia).
Apply the fundamental principle of emergency medicine: ABCs (Airway, Breathing, Circulation). Flail chest is a critical 'Breathing' problem.
Evaluate the options based on the ABC priority. The most immediate intervention for a 'Breathing' problem is to ensure adequate oxygenation.
Consider the other options in the context of timing and indication. IPPV is for respiratory failure (a later stage), chest tubes are for specific complications (pneumo/hemothorax), and surgery is a definitive, not initial, treatment.
