- A. Radiation therapy is used to cure and control liver cancer.
- B. Radiation therapy is used to prevent future cancer development.
- C. Radiation therapy is used to cure and control lung cancer.
- D. Radiation therapy is used to prevent or relieve distressing symptoms.
Correct Answer: D
Rationale: A. Radiation of the upper chest would have no effect on the liver located in the abdominal cavity. B. Preventing future cancer development is not the intention of radiation therapy for this client. C. Radiation therapy reduces size of tumors but would not be expected to cure cancer in this client. D. Primary liver tumors commonly metastasize to the lung, which can cause obstructive symptoms. In this client, radiation therapy to the lung would be used as a palliative care modality to help relieve distressing symptoms such as dyspnea.
