**Core Concept**
The treatment of lung abscess involves a combination of antibiotics, drainage, and supportive care. The goal is to eliminate the infection, resolve the abscess, and prevent complications such as bronchopleural fistula or empyema.

**Why the Correct Answer is Right**
The best treatment modality for a lung abscess is usually a combination of antibiotics and drainage, either through percutaneous catheter placement or thoracostomy tube. Antibiotics are chosen based on the likely causative organism, such as anaerobic bacteria or Staphylococcus aureus. Drainage is often necessary to remove the accumulated pus and promote healing. In some cases, surgical intervention may be required for large or complicated abscesses.

**Why Each Wrong Option is Incorrect**
**Option A:** Antibiotics alone may not be sufficient to resolve the abscess, as the infection can persist in the abscess cavity.
**Option B:** Chest physiotherapy may help mobilize secretions but is not a primary treatment for lung abscess.
**Option C:** Surgical resection is typically not necessary for lung abscess, as it is usually a localized infection.

**Clinical Pearl / High-Yield Fact**
A lung abscess is a medical emergency that requires prompt treatment to prevent complications. The treatment plan should be tailored to the individual patient's needs, taking into account the size and location of the abscess, the underlying cause of the infection, and the patient's overall health status.

**Correct Answer: C. Surgical resection is typically not necessary for lung abscess, as it is usually a localized infection.**
