Choice A rationale:

Surgical debridement to remove infected bone tissue is often part of the treatment plan for osteomyelitis.

However, it is not the first-line treatment and is usually performed in conjunction with antibiotic therapy.

Therefore, it is essential to mention antibiotic treatment as well.

Choice B rationale:

Analgesics and anti-inflammatory medications may be prescribed to manage pain and inflammation associated with osteomyelitis, but they are not the primary treatment.

Antibiotics to treat the infection are the primary focus of treatment.

Choice C rationale:

Intravenous antibiotics for an extended period (4-6 weeks) are a crucial part of the treatment plan for osteomyelitis.

These antibiotics are necessary to combat the infection effectively and prevent its spread.

Choice D rationale:

Monitoring circulation, sensation, and motor function is essential in some cases of osteomyelitis, particularly if the infection is severe or involves a joint.

However, it is not the primary treatment plan, and it is not mentioned in isolation from antibiotic therapy, which is the core treatment.
