Question 20

The dental hygienist should practice the local anesthetic technique until it becomes routine.

Question 21

When infection is present,it is recommended to administer nerve blocks away from the area of infection because the acidic nature of the anesthetic deposited into acidic tissue from an infection decreases the ability of the anesthetic to readily dissociate for nerve penetration.

Question 23

Following the initial negative aspiration,the dental hygienist should rotate the barrel of the syringe about 45 degrees and aspirate a second time.This ensures that the needle is not located within a blood vessel and possibly abutting the blood vessel wall,providing a false-negative aspiration.
