Question 6 of 15
Yes, that answer is right.
In descending order, the injections with the highest rate of positive aspiration are:
IAN
mental/incisive
PSA
While positive aspiration can occur with any injection, it is more likely with the above-listed injections. Therefore, it is recommended that with these injections, a 25-gauge needle be used since aspiration of blood will be easier and more reliable with the larger diameter (lumen).
