ESSAY

1. Name the four anesthetic administration techniques.

ANS:
Topical, infiltration injection, field block, and nerve block

REF: Page 202

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

ANS:
Drug used and concentration, vasoconstrictor used (if any), amount administered in milligrams, the gauge and type of needle, the injections given, the time of administration, and any patient reactions

REF: Page 215

TRUE/FALSE

1. The dental hygienist should practice the local anesthetic technique until it becomes routine.

ANS: F
Correct: Dental hygienists should never let the administration of local anesthetics become routine.

REF: Page 216

2. 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.

ANS: F

Correct: If two quadrants are to be completed in a single visit, anesthesia should be administered to the upper and lower quadrants on the same side of the patient’s face.

REF: Page 216

3. Nerve block anesthesia provides profound anesthesia over a larger area with fewer injections needed.

ANS: T REF: Page 216

4. 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.

ANS: T REF: Page 216

5. If the harpoon disengages during an aspiration, the clinician must remove the needle from the tissue and re-embed the harpoon in to the rubber stopper.

ANS: T REF: Page 216

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

ANS: F
Correct: To provide safe and comfortable injections, the clinician should administer the anesthetic solution slowly.

REF: Page 216

7. Informed consent is when the patient gives the clinician permission to perform the dental procedure.

ANS: T REF: Page 201

8. Both field blocks and nerve blocks are injections in which the local anesthetic is deposited near large terminal nerve branches.

ANS: T REF: Page 202

9. The incidence of occupational exposures is reduced for the experienced clinician.

ANS: F
Correct: The incidence of occupational exposures is not reduced for the experienced clinician.

REF: Page 219

10. The self-sheathing anesthetic needle is an engineering design that reduces the clinician’s exposures to blood and other potentially infectious material.

ANS: T REF: Page 219

11. 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.

ANS: F
Correct: Safety controls for needles and other sharps are mandatory. These include placing used disposable syringes and needles, scalpel blades, and other sharp items in appropriate puncture-resistant containers.

REF: Page 219

12. Needles should be carefully bent before disposing of them in the sharps container.

ANS: F
Correct: Needles should never be bent or broken before disposal because the practice requires unnecessary manipulation and therefore involves greater chance for needlesticks to occur.

MULTIPLE CHOICE

1. 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?
a. Positive aspiration
b. Negative aspiration
c. Aspiration
d. All of the above

ANS: B
A negative aspiration is the correct term for the presence of a clear air bubble, or no return after definite movement backward of the rubber stopper.

REF: Page 201

2. Successful delivery of local anesthetic agents depends on which of the following?
a. Effective patient management
b. Safe administration of the drug
c. Patient assessment
d. All of the above

ANS: D
Successful delivery of local anesthetic agents depends on effective patient management and patient assessment and the safe administration of the drug.

REF: Page 202

3. Which of the following are considerations the clinician must respect when choosing the appropriate administration technique?
a. Area to be treated
b. Duration of anesthesia needed
c. Comfort needs of the patient
d. All of the above

ANS: D
When choosing the appropriate administration technique, the clinician must consider the area to be treated, the duration of the anesthesia needed, and the comfort needs of the patient.

REF: Page 202

4. What is the main advantage of the nerve block over other types of anesthesia?
a. It can be administered at a distance from the area of treatment.
b. It is administered in the vicinity of a nerve trunk.
c. Provides profound pulpal and soft tissue anesthesia over a larger area.
d. It has less potential for piercing the artery or vein that accompanies the nerve.

ANS: C
An advantage of the nerve block over the other techniques is that it provides profound pulpal and soft tissue anesthesia over a larger area.

REF: Page 202

5. What can the clinician do to prevent an emergency situation from occurring while administering local anesthesia?
a. Provide effective communication
b. Offer psychological support
c. Do a thorough patient assessment
d. All of the above

ANS: D
Providing effective communication and psychological support is essential to build patient confidence and to reduce the risk of an emergency procedure. Another step in preventing emergencies is the preanesthetic patient assessment.

REF: Pages 202, 203

6. What can the clinician safely do if a patient is experiencing excessive bleeding while undergoing root planing?
a. Administer more anesthesia plus vasoconstrictor
b. Infiltrate epinephrine 1:50,000 in small amounts directly into area of bleeding
c. Use a larger volume of anesthetic
d. Reschedule the patient for another appointment after some tissue healing

ANS: B
For excessive bleeding, it is recommended to infiltrate epinephrine 1:50,000 in small amounts directly into the area of bleeding for greatest visibility and bleeding control.

REF: Page 203

7. Local anesthesia is best administered by quadrants or sextants. It is an effective patient management strategy.
a. Both statements are true.
b. Both statements are false.
c. The first statement is true; the second statement is false.
d. The first statement is false; the second statement is true.

ANS: A
Both statements are true. Local anesthesia is best administered by quadrants or sextants. It is an effective patient management strategy.

REF: Page 203

8. When administering local anesthesia to the maxillary arch for extensive root planing procedures, what is the correct order of the injections?
a. PSA, MSA, then ASA.
b. ASA, MSA, then PSA.
c. Infraorbital, then PSA.
d. Order does not matter and patient can dictate what makes him most comfortable.

ANS: A
When administering local anesthesia to the maxillary arch for extensive root planing procedures, the correct order of the injections is PSA, MSA, then the ASA.

REF: Page 203

9. Why should the clinician avoid administering local anesthetics to both the mandibular right and left quadrants during a single treatment?
a. To prevent the patient from self-mutilating his/her mouth
b. To prevent toxicity due to the administration of too much local anesthetics
c. To prevent the inability of the patient to control his/her mandible
d. All of the above

ANS: C
The clinician should avoid administering local anesthetics to both the mandibular right and left quadrants during a single treatment to ensure that patient remains able to control his/her mandible.

d. The first statement is false; the second statement is true.
