Exam 11: Basic Injection Techniques

Suggested safety controls for needles and other sharps include placing used disposable syringes and needles,scalpel blades,and other sharp items in appropriate puncture-resistant containers.

If the blood of a positive aspiration does not completely fill the cartridge,the clinician can slightly reposition the needle and attempt a second aspiration.

What should the clinician do while waiting for local anesthetic to take effect for her patient?

Successful delivery of local anesthetic agents depends on which of the following?

If repeated positive aspirations are observed at the same injection site,it may be necessary for the dental hygienist to consider postponing treatment because repeated penetrations in the same area can cause bleeding at the target location and increase risk of hematoma,trismus,postoperative pain,and infection.

To provide safe and comfortable injections,the clinician should administer the anesthetic solution quickly.

Best practices to alleviate a patient's anxiety about local anesthetic include:

Local anesthesia is best administered by quadrants or sextants.It is an effective patient management strategy.

What is the correct dental term for the presence of a clear air bubble,or no return after definite movement backward of the rubber stopper?

List the specific local anesthetic information that should be included in the chart documentation.

Why should the clinician avoid administering local anesthetics to both the mandibular right and left quadrants during a single treatment?

When infection is present,it is recommended to administer nerve blocks away from the area of infection because the acidic nature of the anesthetic deposited into acidic tissue from an infection decreases the ability of the anesthetic to readily dissociate for nerve penetration.

What term describes the injection site where the bevel of the needle is covered with tissue?

Which of the following are benefits of taut tissue retraction at the penetration site?

What can the clinician safely do if a patient is experiencing excessive bleeding while undergoing root planing?

When half-mouth treatment is planned,the inferior alveolar and buccal blocks are given first,then the maxillary facial,and then palatal injections follow with instrumenting proceeding first on the maxillary arch.This allows time for the entire mandibular arch to become completely anesthetized.

Each of the following is true regarding establishing a fulcrum while administering local anesthesia EXCEPT one.Which one is the EXCEPTION?

Cartridges of local anesthetics contain 1.8 mL of solution-except articaine,which contains 1.7 mL of solution.How fast should articaine be injected?

If two quadrants are to be completed in a single visit,anesthesia should be administered to the upper right and left quadrants or to the lower right and left quadrants.

Why is the pterygoid venous plexus an area of concern when administering the PSA?
