Which statement correctly reflects a NOT one of the six ways to reduce unnecessary dose?

• A. Unnecessary exams
• B. Repeat exams
• C. Technique
• D. Shielding

Answer: (A)

Reducing unnecessary dose comes from concrete actions that lower exposure while preserving diagnostic quality: making sure each exam is justified, optimizing exposure technique to use the smallest amount of radiation needed, shielding exposed areas, limiting the beam with proper collimation, and avoiding repeats by getting the image right on the first try. The statement about unnecessary exams describes a problem to avoid rather than a specific action you take to cut dose. It doesn’t spell out a technique, device, or workflow change that reduces exposure. The other options point to actual dose‑saving actions, such as adjusting technique and using shielding, and the overall goal of not repeating exams.
