Which observation might suggest that a client is responding positively to buspirone treatment?

A reported decrease in physical anxiety symptoms is a strong indicator that a client is responding positively to buspirone treatment. Buspirone is primarily prescribed for the management of anxiety disorders, and it works by influencing serotonin and dopamine receptors in the brain, which can help reduce feelings of anxiety. When a client experiences a reduction in physical symptoms associated with anxiety, such as tension, restlessness, or rapid heartbeat, it suggests that the medication is effectively addressing their anxiety.

The other options, such as increased sleep disturbances, development of tolerable side effects, or increased reliance on medication, do not indicate a positive response to treatment. For instance, increased sleep disturbances could signify that the medication is not working effectively or that the client is experiencing side effects. Similarly, while tolerable side effects might reflect some level of tolerance to the medication, they do not necessarily demonstrate an improvement in anxiety symptoms. Increased reliance on medication could suggest dependency rather than improvement, indicating that the client may not be effectively managing their anxiety without the medication.
