Injection of a local anesthetic into an inflamed area usually has a less than optimal result. Which of the following best explains why?

During the administration of local anesthesia, an intravascular injection will occur most often in a/an

inferior alveolar block
NDEB released questions part 2 set 1

Aspiration prior to a local anesthetic injection reduces the

possibility of intravascular administration.
NDEB released questions part 2 set 1

Satisfactory local anesthesia is often difficult to obtain in the presence of infection near the injection site because of

the acidity of the infected tissue
NDEB released questions part 2 set 3

A patient suddenly becomes pale and sweaty after an injection of 4ml of lidocaine 2% with epinephrine l:l00,000.
The radial pulse is slow and steady. The respiration is slow. The blood pressure is 80/60. What is the most probable diagnosis?

Incipient syncope.
NDEB released questions set 3

It is difficult to obtain satisfactory anesthesia in the presence of infection near the injection site because

acidity of the infected tissue inhibits action of the anesthetic agent.

An accidental injection of diazepam into an artery instead of a vein may cause

All of the above.

A gluteal intramuscular injection may be safely administered in which quadrant?

Upper lateral.

A healthy, 23 year old male patient experiences a warm sensation, diaphoresis, nausea, light headedness and then loses consciousness approximately 30 seconds following the injection of 1.8ml of 2% lidocaine with 1:100,000 epinephrine for an inferior alveolar nerve block. What is the most likely diagnosis for his situation?

Syncope

Aspiration is carried out prior to a local anaesthetic injection in order to reduce the

possibility of intravascular administration.
NDEB released questions part 2 set 5

After an inferior alveolar nerve block injection, a patient would develop seventh nerve paralysis if the injection was made into the

retroparotid space
NDEB released questions part 2 set 15

The use of aspirating syringes for the administration of local anesthetics is
recommended because
1. the effectiveness of local anesthesia is increased.
2. aspiration of blood is proof that the needle is in an intravascular location.
3. their use removes the hazard of rapid injection and provides a distinct saving of time.
4. their use reduces the frequency of accidental intravenous injection.

Which of the following are possible causes of Bell’s Palsy?
1. Incorrect injection technique.
2. Viral infection.
3. Inflammation of the facial nerve.
4. Surgical trauma.

Aspiration prior to a local anesthetic injection reduces the

possibility of intravascular administration.

Epinephrine (vasoconstrictor) is included in local anesthetics for the following reasons:
1. It prolongs the duration of action
2. It reduces toxicity
3. It reduces the rate of vascular absorption
4. lt provides a hemostatic effect to reduce bleeding at injection site

All of the above
Anesthetics set 1

Injection of a local anesthetic into an inflamed area usually has a less than optimal result. Which of the following best explains why?

inflammation reduces the availability of the free base

the prostaglandins stabilize the nerve membrane

the drug will be absorbed more rapidly because of the increased blood supply

the chemical mediators of inflammation will present a chemical antagonism to the anesthetic
