Final answer:

Needle deflection during an injection can increase with a decrease in needle gauge. Other factors can include the depth of the injection and the length of the needle.

Step-by-step explanation:

The question pertains to factors that can affect needle deflection during an injection. Needle deflection can occur due to various reasons:

  • Depth of injection: A deeper injection may increase the chance of deflection due to the increased distance the needle has to travel through tissue, which can cause more resistance.
  • Needle length: A longer needle can bend more easily compared to a shorter one, which may lead to increased deflection.
  • Needle gauge: A smaller gauge needle, which has a larger diameter, is stiffer and less likely to bend, whereas a larger gauge needle (smaller diameter) is more flexible and can deflect more easily.

Therefore, when considering the options provided, needle deflection increases with decrease in needle gauge, among other factors.
