National Dental Assisting Examining Board (NDAEB) Practice Exam

Which of the following is NOT an important measure in preventing airway obstruction during dental treatment?

1. Use of high volume evacuator (HVE)

2. Use of dental dam

3. Placement of a throat pack

4. Application of anesthesia

The correct answer is: Application of anesthesia

In preventing airway obstruction during dental treatment, applying anesthesia is not specifically aimed at managing or preventing airway obstruction. While anesthesia is crucial for patient comfort and pain control during procedures, it does not provide a direct safeguard against items that might obstruct the airway, such as debris, instruments, or tissue. In contrast, utilizing a high volume evacuator (HVE) is essential for removing excess fluids and debris from the oral cavity, which can help maintain a clear airway. The use of a dental dam serves a similar purpose by isolating the treatment area and preventing materials from being aspirated. Additionally, the placement of a throat pack can help prevent items from falling into the throat, thus reducing the risk of airway obstruction. All these measures are specifically designed to ensure that the patient's airway remains clear, while anesthesia mainly addresses patient comfort rather than airway management.
