Local Anesthesia Practice Exam
The mandibular division of the fifth cranial nerve passes through what foramen? -
ANS-Foramen Ovale
The nasopalatine nerve passes through the: - ANS-Incisive foramen
The maxillary division of the fifth cranial nerve is:
mixed sensory and motor
sensory only
motor only - ANS-sensory only
Which of the following is NOT associated with the mandibular division of the fifth cranial
nerve:
Inferior Alveolar
Long Buccal
Lingual
Nasopalatine - ANS-Nasopalatine
Which injection(s) is necessary to anesthetize the entire palate on one side? -
ANS-Nasopalatine and Greater Palatine
When administering the IANB injection how far would you typically insert the needle? -
ANS-3/4 length of needle or 20-25mm
During nerve depolarization which ions create an electrical charge? -
ANS-Potassium/Sodium
When administering local anesthetic when do you aspirate? - ANS-Immediately before
administering the anesthetic
Which family of local anesthetics is metabolized by pseudocholinesterase? -
ANS-Esters
Topical anesthetics are least effective when placed upon: - ANS-Keratinized tissue
Topical anesthetics:
a. easily absorbed/transported through bloodstream
b. cause little or no systemic problems
, c. are broken down in the liver
d. are more effective than injected anesthetics - ANS-b. cause little or no systemic
problems
Psychogenic pain: - ANS-shows no organic causation
What is the maximum dose of epi for a cardiac patient? - ANS-0.04mg
If a local complication of hemotoma occurs what treatment should be taken? -
ANS-Immediate application of cold to the area and pressure application to the affected
area.
Hematoma is most likely to occur when needle enters the : - ANS-pterygoid plexus
Which compound is used as an antioxidant with in the cartridge? - ANS-Sodium bisulfite
Vassopressors added to local anesthetic solutions: - ANS-reduce bleeding
prolong the action of the local anesthetic
reduce toxicity by slow absorption
Burning sensations upon injection can be attributed to: - ANS-pH of solution
injection administered too fast
Cartridge wiped with alcohol prior to administration
Needle breakage occurs most frequently due to: - ANS-patient movement
bent needle
A myelinated nerve: - ANS-allows faster conduction of impulses
Which area may not be anesthetized by PSA Block? - ANS-mesiobuccal root of the
maxillary 1st molar
A patient with liver and kidney disease: - ANS-will require dose modification for the
amide local anesthetic
Allergic reactions related to local anesthetic is most likely with: - ANS-Topical anesthetic
Trismus - ANS-common local complication of IANB injection
results in muscle soreness and stiffness
resolves quicker with warm compresses and exercise
