CDCA local anesthesia exam review
questions with correct answers
which has thicker cortical plate, maxillary or mandibular? - CORRECT
| | | | | | | | | |
ANSWER✔✔-mandibular (this decreased the amount of the local | | | | | | | |
anesthesia molecules that can penetrate to nerves during infiltration
| | | | | | | | |
injections)
due to the thickness of cortical bone, which is a good option for local
| | | | | | | | | | | | | |
anesthetic in the mandibular arch during infiltrations? - CORRECT
| | | | | | | | |
ANSWER✔✔-Articaine (Septocaine) is sometimes effective for mand. | | | | | | |
infiltrations (4% vs. 2% for lidocaine) due to the increased number of
| | | | | | | | | | | |
molecules
hematomas are most common with which type of injection, and why? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-PSA due to nicking a vessel in the pterygoid
| | | | | | | | | |
plexus of veins | |
what is the TX for a hematoma? - CORRECT ANSWER✔✔-pressure, cold
| | | | | | | | | | |
compresses on/off, NSAIDS, and time. | | | |
a positive aspiration when administering a PSA is due to what? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-aspirating hemorrhage caused by injection
| | | | |
,what are the three most common locations for hematomas to occur? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-1. PSA | |
2. IA |
3. mental
|
blanching of the tissue following/during an injection is caused by what?
| | | | | | | | | |
- CORRECT ANSWER✔✔-vasospasm/vasoconstriction caused by
| | | | | |
epinephrine or brushing against autonomic nerves stimulation
| | | | | | |
vasospasm
the pterygomandibular space/triangle is bordered by what anatomical
| | | | | | | |
structures? - CORRECT ANSWER✔✔-ramus, lateral pterygoid muscle,
| | | | | | |
and medial pterygoid muscle
| | |
the pterygomandibular space/triangle is identified intra-orally by what?
| | | | | | |
- CORRECT ANSWER✔✔-pterygoid hamulus (palpation), coronoid notch
| | | | | | |
(palpation), and pterygomandibular raphe (visual)
| | | | |
the mandibular foramen lies approx. __________________________ of
| | | | | | |
the distance from the anterior border of the ramus to the posterior
| | | | | | | | | | | |
border - CORRECT ANSWER✔✔-1/2 to 2/3
| | | | |
, Antero-posteriorly, the greater palatine foramen is located between the | | | | | | | | |
___________________________. - CORRECT ANSWER✔✔-middle oft | | | | |
he maxillary second molar and the middle of the third molar in about
| | | | | | | | | | | | |
80-90% of patients. | |
all arteries leading to the oral cavity receive blood from what? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-external carotid (most are direct or indirect
| | | | | | | |
branches from the maxillary artery with the exception of the lingula --
| | | | | | | | | | | |
this is a direct branch from the external carotid)
| | | | | | | |
veins from the oral cavity will drain into what? - CORRECT ANSWER✔✔-
| | | | | | | | | | |
internal jugular (both internal and external drain into the
| | | | | | | | |
brachiocephalic veins which drain to the superior vena cava | | | | | | | |
do myelinated or un-myelinated nerves create faster impulse? -
| | | | | | | | |
CORRECT ANSWER✔✔-myelinated (impulses jump from node to node --
| | | | | | | |
node of ranvier)
| | |
what is saltatory conduction? - CORRECT ANSWER✔✔-the process of
| | | | | | | | |
nerve impulses jumping from nodes of ranvier along a myelinated nerve
| | | | | | | | | |
what is the resting potential charges of a nerve? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-inside is negative and outside is positive | | | | | |
