Which of the following is an indication to remove a foreign body from a wound?

• A. Potential for infection
• B. Toxicity
• C. Functional problems
• D. All of the above

Answer: (D)

When deciding to remove a retained foreign body, the guiding idea is to prevent harm from its continued presence. An object in a wound can serve as a source of infection, especially if it is contaminated or organic material that bacteria can colonize. It can also cause chemical irritation or toxicity if the material releases irritants or toxins into surrounding tissue. Additionally, a foreign body can impair function if it obstructs movement, interferes with nerves or vessels, or sits in a location where swelling could trap it or cause injury during use. Each of these scenarios creates a reason to remove the object, so all of the above are indications for removal.
