Withdraw the needle completely, change the direction of the needle, penetrate, and readvanch to the target location.
After arriving at the deposition site, you decide to redirect your needle to achieve effective anesthesia. Which of the following is an appropriate action?
Using fingers to recap the needle when he needle has not entered the patient's mouth
All are the acceptable way to recap a needle EXCEPT one.
Buffered anesthetic
All the following cause a burning sensation when the anesthetic is injected into just tissue EXCEPT one.
Using a 25-gauge needle
All the ways that increase the risk of needle breakage EXCEPT one.
Recap the needle with the one-hand scoop method, discard it and replace it with a new, sterilized needle. Proceed in administering the local anesthesia
As you are about to administer an injection, your needle tip inadvertently touches the patients's disposable bib (clean but not sterile). What should you do?
The part of the shaft that passes through the hub and penetrates the rubber diaphragm of the cartridge, lying within the anesthetic agent of the cartridge.
Cartridge-penetrating end
Expensive
Disadvantages for the wand?
The diameter of the needle
Gauge
Pressure anesthesia
Gauze 2x2 squares are a helpful supplement to the anesthetic armamentarium. Which of the following is NOT a function of a gauze 2x2?
Excessive pull during aspiration and failure to properly engage the harpoon during setup
Harpoon disengagement may occur due to which operator error?
Recapping using the scoop method and disposal in an approved sharps container
How should a clinician properly dispose of anesthetic needles?
Remove the syringe from the patient's mouth, remove the needle, and reengage the harpoon into the rubber stopper
If the harpoon disengages during an aspiration, the clinician should?
Used for topical anesthetic of soft tissue, delivers via pressure, no needle, and in costly
Jet injector syringe
Greater accuracy and increased injection success
Larger needles have what advantages over the smaller gauge needles?
The hallow portion of the needle
Lumen
The size tubular (channel) of the needle is related to the gauge
Lumen
Made of plastic or metal and provides a means to attach the needle to the syringe
The hub and syringe adaptor

Needle adaptor (hub)
Protects the needle that is inserted in the tissue, as well as the cartridge-penetrating end of the needle
Needle sheilds
Used for PDL or intraligamentry injections
Pressure type syringe
Negative pressure
Pulling back on the thumb ring provides _______ and produces an aspiration
25 gauge
Recommended for highly vascular areas and risks of positive aspiration
Inspection and replacement of the finger ring Lubrication of the piston Inspection and replacement of a dull or bent harpoon
Routine maintenance of a reusable syringe includes?
Harpoon
The ___________ is a sharp tip attached to the internal end of the piston that embeds into the cartridge's rubber stopper
Breech loading allows or side loading of cartridge through window

The angled surface of the needle tip that is directed into the tissue to provide a cutting surface that offers little resistance to mucosa as the needle penetrated and withdraws from the tissue
The bevel
Be turned toward the bone
The bevel of the needle should
Anesthetic drug inside the cartridge
