Which local anesthetic agent is classified as an amide and is the most commonly used in dentistry?
Answer: Lidocaine
Lidocaine (Xylocaine) is an amide-type local anesthetic and is the most widely used local anesthetic in dentistry, often combined with epinephrine as a vasoconstrictor.
What is the recommended maximum dose of epinephrine in local anesthetic for a patient with cardiovascular disease?
Answer: 0.04 mg
For patients with significant cardiovascular disease, the maximum dose of epinephrine is 0.04 mg (two cartridges of 1:100,000 epinephrine) per appointment.
Which route of administration is used for nitrous oxide/oxygen sedation?
Answer: Inhalation
Nitrous oxide/oxygen conscious sedation is administered via inhalation through a nasal hood, making it an inhalation route of administration.
What should the RDA do FIRST if a patient develops syncope (fainting) during a procedure?
Answer: Place patient in Trendelenburg (supine with feet elevated) position
For syncope, the first step is to place the patient in the Trendelenburg position (supine with feet elevated above the heart) to restore blood flow to the brain.
Which of the following is a contraindication to the use of nitrous oxide sedation?
Answer: Obstructive nasal passages
Obstructive nasal passages (e.g., severe nasal congestion, deviated septum) are a contraindication to nitrous oxide because the gas is delivered via nasal inhalation.
What percentage of oxygen is included in a nitrous oxide/oxygen sedation mixture at minimum?
Answer: 20%
The minimum oxygen concentration in a nitrous oxide/oxygen sedation mixture is 20% (equal to or greater than atmospheric oxygen), ensuring the patient does not experience hypoxia.
