Which statement indicates that tramadol is effective for the client?

The statement "My pain was better so I was able to sleep after taking that new medicine" indicates that tramadol is effective for the client because it directly points to an improvement in the client's pain levels. Effective pain management is one of the primary goals when prescribing medications like tramadol, which is an analgesic used to treat moderate to severe pain. When a client reports experiencing reduced pain, it suggests that the medication is fulfilling its intended purpose.

The mention of being able to sleep after the pain improvement further reinforces the effectiveness of the medication. Sleep can often be disrupted due to pain, so the ability to rest indicates a significant positive impact of tramadol on the client’s overall well-being.

Other statements do not indicate effectiveness: feeling sleepy is a side effect rather than an indicator of pain relief, experiencing a lot of side effects suggests that the medication might not be tolerable or effective, and not noticing any changes in pain implies that the medication is ineffective. Therefore, the statement about improved pain and subsequent sleep directly demonstrates the effectiveness of tramadol for the client.
