A client with a below-the-knee amputation is experiencing phantom limb pain. Which action by the nurse would be most effective in relieving the pain?
- A. Acknowledging the presence of the pain
- B. Elevating the stump on a pillow
- C. Applying a transcutaneous nerve stimulator unit (TENS)
- D. Rewrapping the stump
Correct Answer: C
Rationale: Applying a TENS unit can help relieve phantom limb pain by stimulating nerves and reducing pain signals. Acknowledging the pain is supportive but does not directly relieve it. Elevating the stump may help with swelling but not specifically phantom pain. Rewrapping the stump may provide comfort but is less effective than TENS for pain relief.
