What statement indicates that a patient with joint pain has effectively responded to pain management interventions?

The statement indicating that the patient has effectively responded to pain management interventions is one where the patient describes their ability to move without pain. This suggests that their pain levels have been significantly reduced, allowing for improved mobility and functionality in daily activities. The ability to ambulate from the bed to the reclining chair without any discomfort signifies a successful outcome of pain management, as it reflects not only the absence of pain during movement but also an increase in the patient's confidence and capability to perform basic activities.

The other statements express either ongoing discomfort or limitations due to pain, which would imply that pain management interventions are not adequately effective. For example, expressing discomfort while flexing the knees or being unable to straighten the legs suggests that the patient is still experiencing significant pain. The statement about urinating without difficulty does not provide insights about the pain related to joint or mobility issues, making it less relevant for evaluating the effectiveness of pain management specifically related to joint pain.
