A nurse is teaching a group of clients who have cancer about radiation therapy. Which of the following activities should the nurse include in the teaching?

Rationale: A. Limit socializing in large crowds: Radiation therapy is a localized treatment and does not make a client contagious. Therefore, there is no need to avoid social gatherings to protect others. Limiting social interaction is not a necessary precaution for clients receiving radiation therapy. B. Decrease time spent outdoors: Radiation therapy can make the skin in the treated area more sensitive to ultraviolet light. Sun exposure can worsen radiation-induced skin reactions such as erythema, blistering, or hyperpigmentation. Clients are advised to limit outdoor time, wear protective clothing, and use sunscreen on exposed areas to prevent exacerbation of damage. C. Decrease intake of fresh fruits or vegetables: Nutrition is crucial during cancer treatment to maintain strength and support healing. Fresh fruits and vegetables provide essential vitamins, minerals, and fiber. There is no recommendation to restrict these foods during radiation therapy unless the client has specific dietary restrictions based on treatment side effects. D. Limit engaging in sport activities that can cause bruising: Radiation therapy does not directly affect platelet function. Limiting physical activity to prevent bruising is more relevant for clients receiving chemotherapy who are thrombocytopenic. Radiation therapy alone does not typically necessitate avoidance of sports that could cause minor trauma.
