How can the clinician correct the problem of hitting bone while administering the PSA
injection?
A. The needle needs to be bent slightly in order to accomplish the necessary needle
angulation.

How do you calculate the amount of epinephrine in a solution? - ANSWER-1% solution
= 10 X 1.8 (or 1.7) = 18mg (or 17mg)
