In needle gauge terminology, which statement is true about lumen size?

Explanation:
In needle sizing, lumen size is inversely related to the gauge designation. A thicker needle (lower gauge) has a larger bore, while a thinner needle (higher gauge) has a smaller bore. This relationship explains why you’ll see faster flow with a thicker needle and finer control with a thinner one. The ideas that all gauges share the same lumen or that lumen size isn’t tied to gauge don't fit because the interior opening actually changes with the gauge designation.
