Answer: A
 The syringe barrel is the part of the syringe that contains the medication, and is used to gauge a precise amount of the anesthetic to be administered.

Answer: I
 Gauge is the measure of the diameter of the needle. The gauge number is an inverse proportion to the diameter, so the higher the gauge number, the thinner the needle.

Answer: B
 A harpoon is a small metal device that is used to pierce the rubber stopper of a medication vial.

Answer: E
 A breech-loading syringe is a type of syringe where the needle is loaded into the barrel of the syringe by sliding it in from the side, rather than screwing it onto the end of the syringe.

Answer: C, D
 The finger grip and thumb ring are ergonomic features of the syringe that allow for comfortable handling and maneuvering during the administration of the anesthetic.

Answer: G
 The shaft is the long, thin, cylindrical part of the needle that connects the bevel to the hub.

Question 2

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-The size of the lumen of the needle

Accepted Answer

The gauge of a needle refers to the size of its lumen, or the inside diameter. A higher gauge number indicates a smaller lumen, which is a key factor in determining the flow rate of fluids through the needle.

Question 3

What is a possible disadvantage of using the self-aspirating syringe?

Accepted Answer

A possible disadvantage of using the self-aspirating syringe is the insecurity of the clinician accustomed to the harpoon-type syringe.

Question 4

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-The metal or plastic hub that attaches the needle to the syringe

Accepted Answer

The syringe adaptor is a metal or plastic piece that connects the needle to the syringe barrel.

Answer: A
 The syringe barrel is the long part of the syringe that holds the medication.

Answer: I
 Gauge refers to the thickness of the needle.

Answer: F
 Bevel refers to the slanted tip of the needle that makes it easier to insert into the skin.

Question 5

Why might the harpoon of the syringe become disengaged during aspiration?

Accepted Answer

The harpoon of the syringe can become disengaged during aspiration when the harpoon is dull or if the harpoon has not been properly engaged during the syringe set-up.

Question 6

Since the syringe was introduced in 1921,what has been the single most important improvement in dental local anesthetic?

Accepted Answer

Since the syringe was introduced in 1921,the single most important improvement in dental local anesthetic has been the addition of the aspirating harpoon,which allows engagement to the rubber stopper of the anesthetic cartridge.

Question 7

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-The sharp tip of an aspirating syringe that allows for aspiration

Accepted Answer

The harpoon is the sharp tip of the aspirating syringe that allows for aspiration.

Answer: I
 The gauge refers to the size of the needle and is important for determining the appropriate anesthesia technique based on the size of the patient and the location of the injection.

Answer: F
 The bevel refers to the angled tip of the needle and plays a role in the ease of insertion and the direction of the anesthesia delivery.

Question 8

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-Used to advance or retract the piston

Accepted Answer

The answer of MATCHING
Match the parts of the anesthetic armamentarium...

Question 9

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-The length of the needle comprised of long tubular metal extending from the tip of the needle to the cartridge penetrating end

Accepted Answer

The shaft is the long tubular metal part of the needle that extends from the tip to the cartridge penetrating end.

Question 10

Established local anesthetic syringe criteria include which of the following?

Accepted Answer

Established local anesthetic syringe criteria include: disposable and packaged in sterile containers,lightweight and simple to use,and able to withstand repeated use and sterilization.

Question 11

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-The semipermeable material located at the top of the anesthetic cartridge

Accepted Answer

The semipermeable material located at the top of the anesthetic cartridge is called the diaphragm. It is responsible for preventing the anesthetic solution from spilling out of the cartridge while allowing the needle to puncture through it to access the solution inside.

Question 12

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-Allows for insertion of the cartridge through the side of the barrel

Accepted Answer

Breech-loading syringe allows for insertion of the cartridge through the side of the barrel.

Answer: B
 Harpoon is used to penetrate the rubber stopper of the cartridge.

Answer: A
 Syringe barrel holds the cartridge and allows for the delivery of the anesthetic solution.

Answer: H
 Syringe adaptor attaches to the syringe barrel and allows for connection to the needle.

Answer: I
 Gauge measures the diameter of the needle and indicates the size of the opening.

Answer: J
 Diaphragm prevents the backflow of blood or tissue into the syringe.

Question 13

The importance of aspirating prior to anesthetic deposition and the potential hazards associated with intravascular injections are widely known and accepted.The self-aspirating syringe achieves the positive pressure for an aspiration without a harpoon.

Accepted Answer

The importance of aspirating prior to anesthetic deposition and the potential hazards associated with intravascular injections are widely known and accepted.The self-aspirating syringe achieves the negative pressure for an aspiration without a harpoon.

Question 14

MATCHING
Match the parts of the anesthetic armamentarium with their function or main purpose.
-Has a large window and a small window for visibility of cartridge

Accepted Answer

The syringe barrel has a large window and a small window for visibility of cartridge, allowing the anesthetist to see how much anesthesia is left in the cartridge.

Answer: B
 The harpoon is used to puncture the rubber stopper of the cartridge, allowing the anesthesia to be drawn into the syringe.

Answer: C
 The finger grip allows the anesthetist to hold onto the syringe while performing the injection.

Answer: D
 The thumb ring is used to push the plunger of the syringe, which in turn injects the anesthesia into the patient.

Answer: E
 The breech-loading syringe is used to load and unload cartridges of anesthesia quickly and safely.

Answer: F
 The bevel is the angled edge of the needle that allows for easier penetration into the tissue.

Answer: G
 The shaft is the long, thin part of the needle that penetrates into the skin and tissue.

Answer: H
 The syringe adaptor is used to attach the needle to the syringe, allowing for accurate delivery of anesthesia.

Answer: I
 The gauge is the measurement of the diameter of the needle, determining the speed at which the anesthesia will be delivered.

Answer: J
 The diaphragm is a rubber seal at the base of the needle that prevents leakage of the anesthesia during injection.

Question 15

What is one disadvantage of using a smaller syringe?

Accepted Answer

The disadvantage of the smaller syringe is the inability of the clinician to deposit the entire cartridge of anesthetic.A small portion is unusable.

Question 16

Which part of the syringe must be pulled back when inserting the anesthetic cartridge?

Accepted Answer

The part of the syringe that must be pulled back when inserting the anesthetic cartridge is the internal end of the piston with the harpoon attached to it.

Question 17

What is produced when the thumb ring of a syringe is pulled back by the clinician,causing retraction of the rubber stopper?

Accepted Answer

Negative pressure is produced when the thumb ring of a syringe is pulled back by the clinician,causing retraction of the rubber stopper.

Question 18

What should the clinician do if the harpoon does become disengaged during aspiration?

Accepted Answer

If the harpoon does become disengaged during aspiration,the clinician should remove the syringe from the patient's mouth,remove the needle,reengage the harpoon,reattach the needle,and then continue with the procedure.
