Pelvic inflammatory disease (PID) is an infection of the female reproductive organs that requires prompt treatment to prevent long-term complications. The treatment modalities of PID involve **antibiotic therapy** to target the causative pathogens.

**Why the Correct Answer is Right**
The correct answer is related to the use of **broad-spectrum antibiotics** to cover the range of possible pathogens, including Neisseria gonorrhoeae and Chlamydia trachomatis.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not specify the use of antibiotics.
**Option B:** Incorrect as it may not cover all the pathogens.
**Option D:** Incorrect because it is not a standard treatment approach for PID.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that PID treatment should be initiated promptly, without waiting for microbiologic results, to reduce the risk of **infertility** and **chronic pelvic pain**.

**Correct Answer:** D. Outpatient oral antibiotic therapy is sometimes an appropriate treatment for mild PID.
