Final answer:
The nurse should document a decreased muscle spasticity as a therapeutic outcome when administering baclofen for a client with a spinal cord injury.
Step-by-step explanation:
The nurse should document a decreased muscle spasticity as a therapeutic outcome when administering baclofen for a client with a spinal cord injury. Spasticity is an excess contraction of a muscle in response to resistance. Baclofen is a medication that helps reduce muscle spasticity by acting as a muscle relaxant. Therefore, a decrease in muscle spasticity would indicate that the medication is effectively helping to relax the muscles.
