What will the nurse include when caring for a child in Buck’s extension?

Choice A reason: Baclofen is a muscle relaxant used for spasticity in MS, not acute exacerbations. It acts on GABA receptors to reduce muscle tone but does not address the acute inflammatory demyelination causing exacerbations, requiring anti-inflammatory treatment.
Choice B reason: Interferon beta-1b is a disease-modifying therapy for MS, reducing relapse frequency by modulating immune responses. It is not used for acute exacerbations, as its effects are long-term, not rapid enough to treat acute inflammatory flares.
Choice C reason: Dantrolene sodium treats spasticity by inhibiting muscle calcium release but is not indicated for MS exacerbations. Acute flares involve immune-mediated demyelination, requiring corticosteroids to reduce inflammation, not muscle relaxants for symptom management.
Choice D reason: Methylprednisolone, a corticosteroid, is the standard treatment for acute MS exacerbations. It reduces inflammation and edema in demyelinated lesions, speeding recovery by suppressing immune-mediated damage to myelin sheaths, making it the appropriate medication for acute flares.

Choice A reason: Frequent neurovascular checks (pulse, sensation, movement) in Bryant’s traction, used for pediatric femur fractures, detect early signs of compartment syndrome or vascular compromise. This prevents complications like tissue ischemia or nerve damage, critical due to traction’s pressure on soft tissues.
Choice B reason: Tight bandages in Bryant’s traction can cause skin breakdown or impair circulation, increasing the risk of pressure ulcers or compartment syndrome. Bandages should be snug but not constrictive to maintain skin integrity and ensure proper traction function.
Choice C reason: Restraining a child from rolling over may prevent traction disruption but increases the risk of pressure ulcers and discomfort. Controlled movement within traction limits is allowed, and restraint does not directly address neurovascular or circulatory complications.
Choice D reason: The child’s buttocks should be slightly elevated in Bryant’s traction to maintain proper alignment and traction force. Resting on the bed negates the traction’s effect, risking bone misalignment and delayed healing, increasing complication risks.
