Question: 1 / 400

The needle with the largest bore is the ____.

18

20

22

14

The needle with the largest bore is indeed a 14-gauge needle. The gauge system for needles is inversely related to the diameter; as the gauge number decreases, the size of the needle increases. Therefore, a 14-gauge needle has a larger inner diameter compared to higher-gauge needles like 18, 20, and 22, which have progressively smaller bores. This larger bore is often desirable in situations where thicker fluids need to be drawn or injected, such as in certain medical procedures or when administering blood products. The ability to accommodate larger volumes more quickly makes the 14-gauge needle particularly useful in emergencies and for specific veterinary or medical applications.
