Final answer:
The nurse should educate the patient on the importance of follow-up appointments to screen for malignancy after the successful treatment of Hodgkin's lymphoma.
Step-by-step explanation:
Regarding teaching a 55-year-old woman who has been successfully treated for Hodgkin's lymphoma, the nurse should include the need for follow-up appointments to screen for malignancy. Unlike other cancers, fertility is not typically a concern at her age, and maintenance chemotherapy is not commonly used in Hodgkin's lymphoma if a patient achieves remission. The application of soothing lotions could be useful if the patient experiences residual pruritus, but the need for screening is imperative given the risk of secondary cancers post-chemotherapy and as a part of ongoing management and vigilance after cancer treatment.
