LA Chapter 11

T or F: Regardless of the amount of blood in the cartridge following a positive aspiration, the best practice is to withdraw the syringe and reinject.

False

T or F: Resting an elbow on a patient's shoulders or chest during injection creates good stabilization and is a safe ergonomic practice.

False

What statement correctly describes a "false-negative aspiration"?

Rotating the syringe slightly a quarter turn and reaspirating will release the bevel from a vessel wall.

The two most important safety steps in the delivery of local aesthetic agents are...

aspiration test and slow delivery

Efforts to reduce stress from the beginning to the end of an injection are enhanced by maintaining a positive, __________ with the patient.

communication

A _______ deposits local anesthetics directly at or near small terminal nerve endings.

infiltration

The _____ refers to the route a needle travels as it advances to what may be referred to as a target site.

needle pathway

A __________ injection deposits local anesthetic near major nerve trunks at a greater distance from the area of treatment, which provides wider areas of anesthesia.

nerve block

The _______ is the specific location where a needle first pierces mucosa.

penetration site

The final safety step during an injection procedure is to properly _____ the needle prior to disposal.

re-cap

What is the primary reason a needle bevel is oriented toward bone during injection?

to reduce trauma to periosteum when bone is contacted.

Most topical anesthetic agents will reach peak effectiveness in about ___________.

1 minute

__________ reduce the risk of inadvertent deposition of drugs into the bloodstream.

Aspirations

What statement BEST describes why retraction of tissue keeping the tissue taut is important during injections?

It allows for ease of needle penetration and establishes a point of stability for the syringe.

What statement describes the correct positioning of the long window of the syringe?

Toward the clinician to permit visibility throughout the injection.

T or F: The most stable position for the syringe is palm up.

True

T or F: The safest route of deposition of local anesthetics allows for the delivery of 1 mL of solution per minute. This means it requires about two minutes to deposit a 1.8 mL cartridge of anesthetic solution. One minute for one cartridge is acceptable, however.

True

The _______ is defined as the anatomical location at which a drug is deposited.

deposition site

The greater the distance from the penetration site to the deposition site, the greater the potential for ___________ of the needle tip.

deviation

A ____________ aspiration can occur when a bevel is in contact with a vessel wall.

false negative

A _________ injection deposits local anesthetics near larger terminal nerve branches.
