A client in the oncology clinic reports her family is frustrated at her ongoing fatigue 4 months after radiation therapy for breast cancer. What response by the nurse is most appropriate?

Rationale: A. This is the most appropriate response because radiation-induced fatigue can persist for several months after therapy due to the body’s prolonged recovery from cellular damage and the metabolic demands of tissue repair. This response validates the client’s experience and provides reassurance that her symptoms are expected, helping reduce anxiety and guilt related to family frustration. B. This is a useful assessment question but does not first acknowledge the client’s concern or provide education about the normal recovery process after radiation. Therapeutic communication begins with reassurance and validation before further assessment. C. This is inappropriate because there is no evidence that vitamin supplementation alone relieves post-radiation fatigue. Encouraging a balanced diet is beneficial, but this statement oversimplifies the issue and may create false expectations. D. Persistent fatigue following radiation is a common side effect and does not necessarily indicate a complication. However, if fatigue worsens or is accompanied by other symptoms (e.g., weight loss, anemia, depression), further evaluation may then be warranted.
