**Core Concept**
Acute lymphangitis is an inflammatory condition characterized by the spread of infection along the lymphatic vessels, typically caused by bacterial infections such as streptococci or staphylococci. The condition requires prompt treatment to prevent further complications and promote healing.

**Why the Correct Answer is Right**
The correct treatment for acute lymphangitis involves the administration of broad-spectrum antibiotics to target the underlying bacterial infection. Rest is also essential to reduce the spread of infection along the lymphatic vessels and promote healing. The lymphatic vessels are a crucial part of the immune system, and the goal of treatment is to prevent further damage and promote the resolution of inflammation. **Antibiotics** such as penicillin or cephalexin are commonly prescribed to treat acute lymphangitis, while **rest** helps to reduce the spread of infection and promote healing.

**Why Each Wrong Option is Incorrect**
**Option B:** Immediate lymphangiography is not a recommended treatment for acute lymphangitis. Lymphangiography is a diagnostic procedure used to visualize the lymphatic vessels and is not typically used to treat acute infections.

**Option C:** Immediate multiple incisions are not a recommended treatment for acute lymphangitis. Surgical incisions may worsen the condition and increase the risk of complications, such as lymphedema or infection.

**Option D:** No special treatment is not a recommended approach for acute lymphangitis. Inadequate treatment can lead to further complications, such as sepsis or abscess formation.

**Clinical Pearl / High-Yield Fact**
In patients with acute lymphangitis, it is essential to administer antibiotics promptly to prevent further complications and promote healing. Rest and elevation of the affected limb can also help to reduce the spread of infection and promote resolution of inflammation.

**✓ Correct Answer: A. Antibiotic and rest**
