Local Anesthesia Prometric
Greater Palatine - ANS-If #15 has a periodontal abscess and you've already given the
PSA, what other injection will you need to numb the lingual?
Free gingival margin - ANS-You are scaling the lingual of #13, where would you give the
injection for an infiltration?
Mucobuccal fold, Mucogingival junction, free gingival margin, or apex of #13
Nasopalatine - ANS-A central incisor has a periodontal defect on the lingual root
surface, what injection would you use?
Cold and compression for 12 hours - ANS-What is the treatment for a hematoma?
Patient has complications metabolizing the drug - ANS-****You are seeing a patient for
SRP and they have Cirrhosis of the liver, what complications could arise from using an
amide local anesthetic?
#1. Works on mucous membranes. #2 not systemically toxic - ANS-*****What best
describes a topical anesthetic?
Keratinized/palatal tissue - ANS-*****Where would topical anesthetic be least affective?
Expiration date on cartridge - ANS-What is the shelf-life of LA?
No problems - ANS-What would happen if you administered 1 ml of solution per min?
A. No problems
B. Discomfort for patient
The infected area is more acidic which does not allow ionization of sodium molecules -
ANS-Why doesn't LA work in infected areas?
What are the safe doses of epinephrine for a cardiac patient and a healthy patient? -
ANS-***0.2 mm for healthy
0.04 mm for cardiac pt
3.4-3.6 - ANS-Some manufactures have changed how many mL of solution are in a
cartridge. How much would be administered if you had given 2 full cartridges?
, IA - ANS-Where is most likely to use a long needle?
1.8 ml - ANS-How much mL is in a single cartridge of LA?
Smaller number, larger lumen - ANS-Which gauge has the smallest lumen?

anteriors?
Greater Palatine and Nasopalatine - ANS-****What injections are needed to anesthetize
the entire palate on one side?
20-25 mm or 3/4 length of the needle - ANS-****How far do you insert the needle on the
IA?
Sodium in and potassium out - ANS-****What happens during depolarization?
