The nurse prepares baclofen for a child with cerebral palsy who just had her hamstrings surgically released. The child's parents ask what the medication is for. Select the nurse's best response.

Choice A reason: Baclofen is not primarily a pain reliever. It is a muscle relaxant used in cerebral palsy to reduce spasticity. Post-surgical pain is managed with analgesics, not baclofen, which targets muscle tone rather than nociceptive pathways, making this response incorrect. Choice B reason: Baclofen does not prevent seizures. It reduces muscle spasticity in cerebral palsy by acting on GABA receptors in the spinal cord. Anticonvulsants, like levetiracetam, are used for seizures, which are not a universal feature of cerebral palsy, making this inaccurate. Choice C reason: Baclofen is not used for bladder control in cerebral palsy. While spasticity can affect bladder function, medications like oxybutynin target bladder issues. Baclofen focuses on skeletal muscle relaxation, not smooth muscle in the bladder, making this an incorrect response. Choice D reason: Baclofen is a muscle relaxant that reduces spasticity in cerebral palsy by inhibiting spinal reflexes via GABA receptors. Post-hamstring surgery, it controls muscle spasms, improving mobility and comfort, making this the correct explanation for its use in this condition.
