Which statement would the nurse include in the teaching for a patient who is to receive radiation therapy for cancer?

• A. You will have to undergo imaging such as CTs or MRIs before you can receive radiation
• B. Radiation therapy is painless and requires no planning
• C. You will not need any blood tests during treatment
• D. Radiation therapy cures all cancers in all patients

Answer: (A)

Key idea: planning and imaging are essential to deliver radiation therapy safely and effectively. Before external beam radiation starts, a planning step uses imaging—often a CT simulation, with MRI or PET-CT as needed—to map the tumor and surrounding organs, define the exact treatment fields, and create immobilization so the patient can be positioned the same way each day. This imaging-guided planning lets the radiation target the tumor precisely while sparing normal tissue, which is why stating that imaging is required beforehand is the correct teaching point. In contrast, the other statements ignore the necessary planning process, overlook the possibility of needing blood tests in some regimens, and wrongly imply that radiation cures all cancers in every patient.
