A client asks the nurse about having a total knee arthroplasty to relieve joint pain. Which factor would place the client at the highest risk for impaired postoperative healing?

Controlled hypertension.

Obesity.

Osteoarthritis.

Mild osteopenia.

Answer and Explanation

The Correct Answer is B

Choice A reason: Controlled hypertension, when managed with medications, poses minimal risk to postoperative healing. Stable blood pressure ensures adequate tissue perfusion, supporting wound healing and recovery. It is not a significant risk factor compared to other conditions that directly impair tissue repair.
Choice B reason: Obesity significantly increases the risk of impaired postoperative healing due to increased mechanical stress on the surgical site, reduced tissue oxygenation, and higher rates of infection. Adipose tissue has poor vascularity, delaying wound healing, and obesity is associated with comorbidities like diabetes, further complicating recovery.
Choice C reason: Osteoarthritis, the primary indication for knee arthroplasty, does not directly impair postoperative healing. It affects joint cartilage but not the body’s wound healing mechanisms, such as collagen synthesis or immune response, making it a less significant risk factor.
Choice D reason: Mild osteopenia, a precursor to osteoporosis, indicates slightly reduced bone density but does not significantly affect soft tissue healing or surgical outcomes. It may influence implant stability long-term but is less critical for immediate postoperative healing compared to obesity.

Correct Answer is B

Explanation

Choice A reason: Two weeks of antibiotics is insufficient for osteomyelitis, a bone infection requiring prolonged therapy to penetrate bone tissue and eradicate bacteria (e.g., Staphylococcus aureus). Short courses risk recurrence or chronic infection, as bone has poor vascularity, slowing antibiotic delivery.
Choice B reason: Osteomyelitis in children typically requires 4–6 weeks of antibiotics to ensure complete bacterial eradication from bone tissue, which has limited blood supply. This duration allows adequate penetration to prevent relapse or complications like abscesses, making it the standard treatment length.
Choice C reason: Two months (8 weeks) exceeds the typical 4–6 week course for uncomplicated pediatric osteomyelitis. Prolonged therapy may be needed for chronic cases or complications, but 6 weeks is sufficient for most acute cases, avoiding unnecessary antibiotic exposure.
Choice D reason: Three months is excessive for most cases of acute osteomyelitis in children. Such extended therapy is reserved for chronic osteomyelitis or resistant organisms, increasing risks of antibiotic resistance or side effects like renal toxicity without added benefit.

A. Take warm baths to promote muscle relaxation. B. Avoid crowds and people with colds. C. Relying on a walker will weaken your gait. D. Take prescribed medications when symptoms occur.

Correct Answer is B

Explanation

Choice A reason: Warm baths may help with MS-related spasticity but are not the priority teaching for cyclophosphamide and methylprednisolone. These drugs focus on immunosuppression and inflammation control, and baths do not address their side effects or infection risks.
Choice B reason: Cyclophosphamide and methylprednisolone are immunosuppressants, reducing white blood cell counts and increasing infection risk. Avoiding crowds and sick individuals minimizes exposure to pathogens, critical for preventing infections like pneumonia in MS patients on these medications.
Choice C reason: Using a walker supports mobility in MS without necessarily weakening gait. It aids safety during exacerbations, and discouraging its use is inappropriate, as it does not address the immunosuppressive risks of the prescribed medications.
Choice D reason: Taking cyclophosphamide and methylprednisolone only when symptoms occur is incorrect, as these drugs require consistent dosing for immunosuppression and inflammation control. Symptom-based dosing reduces efficacy and increases relapse risk in MS management.
