According to the notes, at kVp above 70, the specified measurement in millimeters is 2.5.

According to the notes, at kVp above 70, the specified measurement in millimeters is 2.5.

• A. 1.5
• B. 3.0
• C. 4.0
• D. 2.5

Answer: (D)

When you study these notes, the idea is that some measurements are tied to the kVp setting. The rule here is that for kVp above 70, the specified measurement in millimeters is 2.5. So the best answer is the value that matches that rule: 2.5. The other numbers don’t fit because they would correspond to different kVp ranges or different parts of the guidance. This kind of detail helps keep technique consistent across exposures when you’re working with high kVp settings.
