The nurse is administering the muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention should the nurse implement?

A) Advise the client to move slowly and cautiously when rising and walking: This intervention is essential because baclofen, a muscle relaxant, can cause dizziness, drowsiness, and muscle weakness as side effects. Instructing the client to move slowly and cautiously can help prevent falls and injuries due to these potential side effects. B) Monitor intake and output every 8 hours: Monitoring intake and output is not directly related to the administration of baclofen. While it is essential to monitor fluid balance in some situations, it is not specifically indicated in this case. C) Ensure the client knows to stop baclofen before using other antispasmodics: While it is important to avoid concurrent use of multiple antispasmodic medications without proper medical supervision, stopping baclofen abruptly without medical guidance can lead to withdrawal symptoms. Therefore, this intervention is not appropriate without further clarification from the healthcare provider. D) Evaluate muscle strength every 4 hours: While monitoring muscle strength is essential for clients receiving muscle relaxants, such as baclofen, evaluating it every 4 hours may not be necessary unless there are specific concerns or as directed by the healthcare provider. Monitoring for signs of muscle weakness or adverse effects should be ongoing but may not require such frequent assessments.
