Exam 9: Armamentariumsyringe Preparation

What is the name of a plastic,single-use or partially disposable syringe that utilizes a retractable plastic sheath that locks over the needle upon removal from tissue?

What is a possible advantage of using the computer-controlled syringe?

Which gauge needle is recommended for use for areas where there is a high risk for a positive aspiration?

To prevent accidental needle stick exposures to the clinician,the clinician should wear thick utility gloves to protect herself.Needle stick injuries typically occur from inattention by the clinician or unexpected patient movement.

Which of the following is an advantage of the plastic breech-loading aspirating syringe?

A patient presents to your office asking for a needleless injection.What anesthetic method is the patient referring to?

Which of the following is likely to increase the incident of needle breakage?

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

What is the weakest part of the needle?

It is recommended that the clinician know the location of the uncovered needle tip at all times.Why?

Manufacturer recommendations for the routine maintenance of reusable syringes include:

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

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

What is an advantage of using the pressure-type syringe over the conventional type of syringe?

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

The cartridge silicone rubber stopper is slightly indented from the rim of the glass barrel.Cartridges that have rubber stoppers that are not indented slightly should be discarded.

Larger-gauge needles provide less tissue deflection during significant needle penetration because of the greater rigidity of larger gauge needles.

Which of the following describe topical antiseptic placement?

Because of the cost of the "needleless" injection,what is an alternative cost-effective anesthetic that will produce results similar to those of the needleless injection?

Small bubbles (1-2 millimeters)trapped in the anesthetic cartridge are harmless because they are produced by nitrogen gas bubbled into the solution during the manufacturing process.
