National Dental Assisting Examining Board (NDAEB) Practice Exam

Which of the following is a potential effect of contaminated anesthetic solutions?

1. Cardiac arrest

2. Improved efficacy

3. Parathesia

4. Faster recovery

The correct answer is: Parathesia

Contaminated anesthetic solutions can lead to several adverse effects, and one of the potential effects is paresthesia. Paresthesia refers to abnormal sensations in a specific area, such as tingling, numbness, or a 'pins and needles' feeling. This can occur due to the presence of contaminants, such as bacteria or toxins, in the anesthetic solution, which can cause irritation or damage to the nerve tissues during administration. Understanding the ramifications of contaminated anesthetic solutions is crucial, as the integrity of these solutions directly impacts patient safety and the quality of dental care. Paresthesia can also result from mechanical trauma or chemical irritants; however, in this context, the focus is on the implications of using compromised anesthetic agents. In contrast, other options such as cardiac arrest are primarily associated with systemic reactions or complications from anesthesia but are not commonly linked directly to contamination. Improved efficacy and faster recovery do not align at all with the consequences of using contaminated anesthetics, as these imply a beneficial outcome, which is not possible when safety is compromised.
