**Core Concept**
The management of a lacerated wound involves assessing the wound for signs of infection, contamination, or significant tissue damage, and choosing the most appropriate method to promote healing, prevent infection, and minimize scarring.

**Why the Correct Answer is Right**
For a lacerated wound that is more than 2 hours old and has been contaminated, the most appropriate initial management is to clean and debride the wound. This involves gently removing any dirt, debris, or dead tissue from the wound to promote healing and prevent infection. The use of sterile saline solution and a mild antiseptic, such as povidone-iodine, can help reduce bacterial load and prevent infection.

**Why Each Wrong Option is Incorrect**
**Option A:** Immediate suturing of a contaminated wound is not recommended, as this can push bacteria deeper into the wound and increase the risk of infection.
**Option B:** Applying a topical antibiotic ointment alone is not sufficient to manage a contaminated wound, as it may not penetrate to the deeper tissue layers and may not be effective against all types of bacteria.
**Option D:** Using a tourniquet to control bleeding in a leg wound is not necessary and may cause more harm than good, especially if the wound is deep or has significant bleeding.

**Clinical Pearl / High-Yield Fact**
When managing a lacerated wound, it's essential to assess the wound for signs of infection, such as redness, swelling, increased pain, or purulent discharge, and to consider the use of tetanus prophylaxis if the wound is contaminated.

**Correct Answer:** A. Clean and debride the wound.
