Local Anesthesia NERB Study guide
2024
What nerve was damaged if the anterior 2/3 of the tongue has a loss of sensation? -
Lingual
What type of injection would be used to achieve homeostasis? - Infiltration
Where are needles disposed? - Hazardous sharps
A burning feeling from an injection can be caused by what? - Too fast of an
insertion or the preservative.
Why would you use caution with Amides and a patient who has Cirrhosis? -
Amides are metabolized in the liver. Cirrhosis is liver failure.
The mandibular division passes through which foramen? - Foramen Ovale
Treatment for hematoma? - Apply pressure for 2 minutes, ice the area, use a warm,
moist towel 4-6 hours after, and rinse with salt water.
Primary reason for needle breakage? - Weakening of the dental needle by bending
it before insertion. Another reason: patient movement.
How is topical anesthetic best described? - It is absorbed through mucosal tissue.
, How far are you into tissue when you first hit bone on the IA block? - 1 inch.
How much epinephrine for a cardiac patient? - 0.04 mg
How much epinephrine for a healthy patient? - 0.20 mg
Foramens & nerves that enter and exit: - Foramen Rotundum - Maxillary nerve
Foramen Ovale - Mandibular nerve
Mandibular Foramen - IA nerve
Incisive Foramen - Incisive nerve
Mental Foramen - Mental nerve
What topical anesthetic is not absorbed systemically? - Benzocaine
What injection would numb the lower lip? - Mental
What happens during depolarization? - Reverse polarity = sodium in & potassium
out
Which type of nerve transmits impulses faster, myelinated or unmyelinated? -
Myelinated.
How do you safely recap a needle? - One-handed scoop method; lay cap on tray
and scoop up the cap with the needle using one hand.
What is the role of sodium bisulfite in local anesthesia? - It is an antioxidant that
prevents oxidation of the vasopressor by oxygen, which might be trapped in the
