Which of the following reasons best describes why it is advantageous to use a 25 gauge long needle for an IA nerve block? Greater depth of penetration, greater accuracy of aspiration outcomes, less needle deflection Comfort level during penetration, greater depth of penetration, low risk of negative aspiration Ease of penetration through fibrous submucusal tissues, greater depth of penetration, low risk of positive aspiration Greater depth of penetration, less needle flexibility when contacting bone to determine deposition site, high risk of positive aspiration

Greater depth of penetration, greater accuracy of aspiration outcomes, less needle deflection If you are choosing to use a 25 over a 27, the gauge importance should be stated In the answer. It states less needle deflection in the correct answer, which is important when dealing with deep penetration you want a thicker gauge, so there is less needle deflection.

What is the best correction to make during an IA injection when premature bony contact is met at less than one half of the penetration depth? Withdraw the syringe to minimize tissue trauma and reinject. Partially withdraw the needle, reposition syringe over the contralateral canine and re-advance the needle until bony contact is met. Reposition syringe toward the contralateral canine and re-advance the needle until bony contact is met. Partially withdraw the needle, reposition syringe over the contralateral canine, advance needle to clear resistance, then reposition the syringe over the premolars, and re-advance the needle until bony contact is met.
