Multiple Choice

1. Which of the following effects is prevented from occurring on the target nerve during the administration of a local anesthetic agent?

a. Resting potential b. Action potential c. Refractory period d. Repolarization

ANS: B

Feedback

A The resting potential occurs when the difference in charge exists and the outside of the nerve cell membrane has a positive charge, while the inside has a negative charge. It occurs in the nonstimulated nerve.

B Local anesthetic agents are administered to prevent an action potential, which is a rapid depolarization of the nerve cell membrane resulting in generation of a nerve impulse. An action potential temporarily reverses the resting potential that exists.

C The refractory period refers to a brief period after an action potential, during which the nerve CANNOT be stimulated.

D The repolarization reestablishes the resting potential.

25. What structure when DIRECTLY damaged also results in the disruption of the nasopalatine nerve?

ANS: B

Feedback

A The nasal bones are paired small oblong facial bones that lay side by side, fused to each other to form the bridge of the nose in the midline superior to the piriform aperture. Instead, the nasopalatine nerve travels along the nasal septum.

B Anteriorly, the nasal septum is formed by both the perpendicular plate of the ethmoid bone superiorly and the nasal septal cartilage inferiorly. The posterior parts of the nasal septum are formed by the vomer. The nasopalatine nerve originates in the mucosa of the anterior hard palate, palatal to the maxillary central incisors. The right and left nasopalatine nerves enter the incisive canal by way of the incisive foramen, deep to the incisive papilla, thus exiting the oral cavity. The nerve then travels along the nasal septum.

C The frontal bone is a single cranial bone that forms the anterior part of the skull superior to the eyes in the frontal region, and includes the forehead, the roof of the orbits, and part of the nasal cavity. Instead, the nasopalatine nerve travels along the nasal septum.

26. When periodontal scaling on the palatal gingival tissue of the maxillary right second molar under block anesthesia administered ONLY to the maxillary right posterior sextant, the patient begins to gag without initiation by the clinician. What nerve was inadvertently anesthetized so as to cause this situation?

ANS: C Feedback

Correct When administered anesthesia to greater palatine nerve by way of a block, some patients may become uncomfortable and may gag if the soft palate becomes inadvertently and harmlessly anesthetized even without clinician initiation, which is possible given the proximity of the lesser palatine nerve.

Incorrect Greater palatine nerve is already anesthetized by a block and is NOT inadvertent anesthesia since the clinician is scaling the anesthetized palatal gingival tissue of the maxillary second molar. The anesthesia of the nasopalatine nerve by a block results in anesthesia of the anterior hard palate within the maxillary anterior sextant and NOT the posterior hard palate within the maxillary posterior sextant. The middle superior alveolar nerve may be anesthetized by a block due to its coverage of the mesiobuccal root of the maxillary first molar that is within the maxillary right posterior sextant, if the nerve is present, but this does NOT cause gagging as a result of soft palate anesthesia.

a. Sodium gates suddenly open in the membrane to allow sodium ions to pour in.

b. Rapid depolarization of the cell membrane results in an action potential.

c. Resting potential is reestablished again.

d. Propagation of the nerve impulse along the membrane occurs.

e. Sodium gates close and potassium channels open to allow potassium ions to pass to the outside of the membrane.

ANS:

B, D, A, E, C

Feedback

Correct Order

The rapid depolarization of the cell membrane results in an action potential, which then causes propagation of the nerve impulse along the membrane. An action potential is a temporary reversal of the electric potential along the membrane for a brief period. Sodium gates suddenly open in the membrane to allow sodium ions to pour in, bringing a positive charge. At the height of the membrane potential reversal, sodium gates close and potassium channels open to allow potassium ions to pass to the outside of the membrane, reestablishing the resting potential.

ANS: B

Feedback

A The incisive nerve block is used on the mandibular anterior teeth and premolars and does NOT provide any anesthesia to maxillary arch.

ANS: B

Feedback

A The abducens nerve is NOT in the area of the inferior alveolar nerve block and affects movement of the eye, NOT the eyelid.

B The facial nerve provides motor innervation to the muscles of facial expression and can result in the inability to close the eyelid with an incorrect administration of the inferior alveolar nerve block. This can occur with a deeper injection into the parotid salivary gland that contains the facial nerve, causing temporary anesthesia of the nerve and its related structures. This is considered transient facial paralysis. To prevent this complication, the needle needs to contact the medial surface of the mandibular ramus.

C The oculomotor nerve affects movement of the eye, NOT the eyelid.

D The sensory part of the facial nerve does NOT move the eyelid.

21. Which of the following local anesthetic nerve blocks can be involved in the spread of infection to the cavernous sinus?

ANS: C

Feedback

A There is less risk of spread of infection to the cavernous sinus with the anterior superior alveolar nerve block than with the posterior superior alveolar nerve block.

B There is less risk of spread of infection to the cavernous sinus with the inferior alveolar nerve block than with the posterior superior alveolar nerve block.

C The posterior superior alveolar nerve block is administered close to the pterygoid plexus of veins, which communicate with the cavernous sinus. If the needle becomes contaminated, this increases the risk for infection in the area, which can then spread.

D There is less risk of spread of infection to the cavernous sinus with the infraorbital nerve block than with the posterior superior alveolar nerve block.

22. Which of the following local anesthetic nerve blocks MAINLY uses an extraoral landmark on the face when locating the injection site?

ANS: B

Feedback

A The inferior alveolar nerve block is administered at the mandibular foramen on the medial surface of the mandibular ramus. The coronoid notch is used to help locate the injection site and can be palpated intraorally.

B Palpation of the infraorbital rim on the facial surface is used to help locate the infraorbital foramen for the infraorbital nerve block; thus, an extraoral landmark of the face is used when locating the injection site. In addition, extraoral pressure is applied to the infraorbital foramen during the injection.

C It is NOT necessary to palpate any extraoral structure to administer the posterior superior alveolar nerve block.

D It is NOT necessary to palpate any extraoral structure to administer the mental nerve block. Instead, the mental foramen is palpated intraorally.

ANS: A

Feedback

A Both the statement and the reason are correct and related. There MUST never be an injection through an area with an abscess, cellulitis, or osteomyelitis so as to prevent the spread of dental infection; this is considered a needle tract infection.
