Final answer:
Nurses should consider that cancer pain can be acute or chronic and often requires high doses of pain medications for management.
Step-by-step explanation:
When addressing the patient's pain in her plan of nursing care, the nurse should consider that cancer pain can be acute or chronic, and it typically requires comparatively high doses of pain medications. This pain may be a result of both neuropathic and inflammatory processes, which can signal ongoing damage in the body or result from the body's immune response to cancer cells. To manage such pain effectively, nurses must understand that pain perception is subjective, and individualized treatment plans are necessary, which may include a combination of medication use and other therapies tailored to the patient's specific type and stage of cancer.
