**Core Concept**
COPD (Chronic Obstructive Pulmonary Disease) is a chronic inflammatory lung disease characterized by progressive airflow limitation and is often complicated by acute exacerbations. Managing COPD in the ICU requires careful consideration of underlying pathophysiology, including bronchospasm, mucus plugging, and hypoxemia.

**Why the Correct Answer is Right**
Acute exacerbations of COPD are managed in the ICU with supplemental oxygen, bronchodilators, and corticosteroids. Non-invasive ventilation (NIV) is often recommended as a first-line treatment to improve gas exchange and reduce the need for invasive mechanical ventilation. **Option C** is incorrect because invasive mechanical ventilation is typically reserved for patients who fail NIV or have severe respiratory failure.

**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect because systemic corticosteroids are a mainstay of treatment for acute exacerbations of COPD, reducing inflammation and improving lung function.
* **Option B:** Not enough information is provided to determine if this statement is true or false.
* **Option D:** Incorrect because bronchodilators are essential in managing COPD, reducing bronchospasm and improving airflow.

**Clinical Pearl / High-Yield Fact**
A key aspect of managing COPD in the ICU is identifying patients at risk of respiratory failure, including those with increased respiratory rate, decreased oxygen saturation, and increased PaCO2. Early initiation of NIV can significantly reduce the need for invasive mechanical ventilation and improve outcomes.

**Correct Answer:** D. Bronchodilators are essential in managing COPD, reducing bronchospasm and improving airflow.
