Final answer:
The nurse should describe the abnormal reorganization of the nervous system to explain why a 60-year-old diabetes patient experiences the sensation and pain in their amputated leg.
Step-by-step explanation:
The nurse should describe the pathophysiologic process of the abnormal reorganization of the nervous system to explain why a 60-year-old diabetes patient who had a below-knee amputation still feels like their leg is attached and experiences pain. Damage to neurons in the peripheral or central nervous system can result in neuropathic pain, where pain signals sent to the brain are exaggerated. This abnormal reorganization of the nervous system can cause the patient to perceive sensations and pain in the amputated limb.
