Pediatric examination modes should always be used for children. Which statement is true?

• A. Pediatric examination modes are optional.
• B. Pediatric examination modes should always be used for children.
• C. Exposure factors should not be adjusted for children.
• D. Dose savings cannot exceed 20%.

Answer: (B)

Children are more radiosensitive and have smaller anatomy, so imaging their mouths at adult settings can deliver unnecessary dose. Pediatric examination modes are built to address these differences by adjusting exposure factors and geometry to fit a child’s size, often lowering kVp or mA, shortening exposure time, and using appropriate filtration and collimation. Using these presets consistently keeps the dose as low as reasonably achievable while still producing a diagnostic-quality image, which is the fundamental safety principle in radiography for kids.

That’s why the statement that pediatric examination modes should always be used for children is the best choice. If you skip these modes, you’re not optimizing exposure for a child’s size and sensitivity, which can lead to higher-than-necessary doses. Saying exposure factors should not be adjusted contradicts the safety need to tailor the dose to pediatric patients, and claiming that dose savings cannot exceed 20% is inaccurate—proper pediatric settings can yield substantial dose reductions beyond a fixed percentage.
