A nurse is caring for a client who has a severe gangrenous infection of the right lower extremity. The nurse should plan preoperative teaching based on the possibility of which of the following post-operative expectations?

Choice A rationale Amputation for a gangrenous infection removes the source of the nociception and local inflammation, but post-operative pain is expected due to surgical tissue trauma, nerve severing, and muscle spasms. The patient will experience pain, and it will likely be severe initially, thus this statement incorrectly minimizes the immediate post-operative experience. Choice B rationale Post-amputation pain stems from surgical injury, wound healing, and potential phantom limb sensations. Pain management via a multimodal approach, including opioids and regional blocks, is planned to gradually reduce the pain intensity as the surgical wound heals and inflammation subsides over days to weeks, which aligns with this expectation. Choice C rationale A tingling sensation, known as paresthesia, can occur due to nerve irritation or regeneration (neuroma formation) but is an incomplete description. Many patients experience intense phantom limb pain, a complex neuropathic sensation perceived in the missing limb, which is much more severe than simple tingling. Choice D rationale Phantom limb pain is a complex neurophysiological phenomenon, not merely psychological. It involves maladaptive changes in the central nervous system, including cortical reorganization and hyperexcitability of spinal neurons, generating the sensation of pain in the absent limb; therefore, calling it mostly psychological is scientifically inaccurate.
