cell body This part of a sensory nerve is not involved in impulse transmission
depolarization This stage of nerve conduction allows sodium to enter the interior of the
cell
First statement is TRUE; the An expenditure of enery is necessary to activate the sodium
second is FALSE pump. The sodium pump occurs during the depolarization
stage.
The time during which a nerve cannot conduct an impulse just after
the refractory period
completing an impulse is
The administration of a local anesthetic into an area of inflammation
the local anesthetic remains in the
salt form has a decreased anesthetic effect. This can be explained by the
fact that
Mr. Jones' health history reveals liver damage from hepatitis.
the amide group
Because of this fact, care should be taken when administering
anesthetic solution from
acidic salts The local anesthetic solutions injected into the tissues are
Which of the following is a clinically acceptable injectable as well
lidocaine
as topical anesthetic?
lidocaine What is the gold standard to which all other local anesthetics are
compared?
procaine Which one of the following local anethetics is metabolized in the plasma?
Upon injection of an anesthetic containing a vasoconstrictor, all
of the following situations occure, EXCEPT one. Which one is
the exception?
c. decreased duration of anesthesia
a. decreased blood flow to the injection site
b. slow absorption of anesthetic into the bloodstream
c. decreased duration of anesthesia
d. decreased bleeding at the injection site
bupivacaine Which anesthetic has the longest duration of action?
Gingival health can affect the duration of action of a local
Both statements are true
anesthetic. Inflamed tissue at the site of the injection results in
shorter duration of anesthesia.

1 hour What is the typical duration of pulpal anesthesia for 2% lidocaine w/ epi
, 1:100,000?
both plasma and liver Where is articaine metabolized?
It blocks the sodium channel What is the mechanism of action of lidocaine?
The higher the pKa of a local anesthetic, the higher the
The first statement is TRUE; the
concentration of the ionized form. The higher the pKa of a local
second is FALSE
anesthetic, the faster the diffusion into the nerve membrane.
What is the maximum number of cartridges of lidocaine 2%

compromised female weighing 125 lbs?
The first local anesthetic was _____, which was discovered by in
cocaine; Albert Niemann
Germany in the
1860s.
Hydrochloric acid (HCl) What is the acid MOST commonly combined with a local anesthetic drug?
gauge, length, bevel What influences deflection of the needle?
isotonicity of solution The function of sodium chloride in the anesthetic is
normal response to the pH of Burning on injection may be cuased by:
the drug cartridge containing
sterilizing solution cartridge
containing a vasopressor
overheated cartridge
Larger gauge needles should be used when there is a
