A home health nurse is planning to use nonpharmacological pain relief measures for a client who has severe chronic back pain. Which of the following pain management guidelines should the nurse use?

Rationale: A. Distraction changes the client's perception of pain, but it does not affect the cause: Distraction techniques, such as listening to music, engaging in conversation, or performing a hobby, redirect the client’s attention away from painful stimuli. This alters the perception and subjective experience of pain without addressing the underlying pathology. B. Discontinue opioids before trying nonpharmacological methods of pain relief: Nonpharmacological methods are intended to complement, not replace, pharmacologic therapy. Abruptly discontinuing opioids could lead to withdrawal symptoms, uncontrolled pain, and decreased functional ability. C. Use imagery with clients who have difficulty with focus and concentration: Guided imagery requires the client to visualize calming or pleasant scenes, which demands a moderate level of attention and cognitive engagement. Clients with impaired focus or concentration may find imagery challenging, reducing its effectiveness as a pain management tool. D. Pain relief from the use of heat and cold continues for several hours after removal of the stimulus: The analgesic effects of heat or cold application are generally short-term, providing relief only during or immediately after use. Heat promotes vasodilation and muscle relaxation, while cold reduces inflammation and slows nerve conduction. Relief does not persist for hours.
