Question 1

A patient is experiencing moderate signs and symptoms of an overdose of a local anesthetic drug and office emergency protocol has been activated. Which of the following correctly describes the next step?

Accepted Answer

Administering oxygen is a critical step in managing a local anesthetic overdose to ensure adequate oxygenation and prevent hypoxia, which can exacerbate symptoms.

Question 2

Which of the following is the correct response for the management of a severe systemic allergic reaction?

Accepted Answer

The correct management for a severe systemic allergic reaction (anaphylaxis) involves administering 0.3 mg of epinephrine intramuscularly or subcutaneously. Epinephrine is the first-line treatment for anaphylaxis due to its rapid onset of action in reversing the symptoms.

Question 3

Which statement describes the best management protocol for a suspected idiosyncratic reaction to a local anesthetic drug?

Accepted Answer

Idiosyncratic reactions are unpredictable and vary widely among individuals, so the best management protocol involves responding appropriately to whatever signs and symptoms develop, as they can range from mild to severe.

Question 12

A clinician administered a PSA injection with a short, 27 gauge needle, bent at the hub to improve access around the maxillary tuberosity. The penetration site was determined and the needle was inserted to the hub contacting bone. The patient quickly jerked his head causing breakage of the needle. The clinician attempted to remove the needle fragment, probing with a gloved finger and a sterile forceps without success. A radiograph was taken showing the needle against the posterior wall of the tuberosity. He explained to the patient that the needle could remain in place because the body would "wall off" the needle and it would not cause any problems, and that trying to remove the needle would cause unnecessary trauma.
-What needle choice and technique error(s), if any, was/were made prior to the injection?

Question 16

A clinician administered an IA nerve block with a long, 25 gauge needle. Although no contact with bone was made, she was certain that the penetration depth was adequate because only 3 mm of the needle was visible. She confirmed negative aspiration in two planes and deposited one cartridge of 2% lidocaine with 1:100,000 epinephrine. After several minutes, the patient's teeth were not numb however the side of their face, including the lower eyelid, around the mouth and chin, were extremely numb.
-What was the most important technique error made by this clinician?
