What are the DANB exams?

Congratulations on your decision to pursue certification in dental assisting! The DANB (Dental Assisting National Board) exams are your next hurdle. Exactly what can you expect with the DANB exams?

What is the Dental Assisting National Board (DANDB)?

The DANB exams are based on content validation, an analysis of the duties commonly performed in actual dental assisting practice. DANB offers five different certifications: NELDA (National Entry Level Dental Assistant, CDA (Certified Dental Assistant), COA (Certified Orthodontic Assistant), CPFDA (Certified Preventive Functions Dental Assistant, and CRFDA (Certified Restorative Functions Dental Assistant).

The DANB component exams are administered on computer at Pearson VUE test centers. All exams are multiple-choice format containing from 80 questions to 210 questions depending on the exam. The time allotted also varies from test to test with a range of 60 minutes to 165 minutes. Specific information on each of exams, including registration information, exam outlines with topics covered, and reference materials can be found at

Most DANB exams use computer adaptive testing (CAT). CAT adapts to the examinee’s ability level and customizes the exam for a more accurate measurement. Each exam begins with a question on par with the passing standard. If it is answered correctly, the difficulty level increases. If answered incorrectly the level of difficulty becomes easier. The final score is based on the difficulty of the questions that were presented and passed.

Official exam results and certificates will be mailed within 2 to 3 weeks after the exam. Candidates can verify DANB credentials using the online Credential Verification tool.

DANB Expanded Functions General Dental Assisting - FAQ Sample Questions

A patient who has an allergic reaction to medication and loses consciousness should be placed in which position?

Correct Answer:

when a patient experiences an allergic reaction that results in loss of consciousness, the recommended position to lay them in is the supine position. the supine position involves having the patient lie flat on their back with their face upward. this position is crucial for several reasons related to the body's physiological responses during an allergic reaction and unconsciousness.

firstly, placing a patient in the supine position helps maintain an open airway, which is essential for effective breathing. when unconscious, a patient’s muscles, including those that help keep the airway open, can relax, potentially leading to obstruction if the patient is in an upright or prone position. by lying a patient on their back, the airway is naturally kept in a more open and straight alignment, reducing the risk of airway blockage.

secondly, the supine position aids in better circulation and perfusion, which is critical during an allergic reaction. allergic reactions can lead to anaphylactic shock, characterized by a sudden drop in blood pressure. when a patient is supine, gravity uniformly distributes blood, enhancing blood flow to vital organs, including the brain. this can be particularly important to prevent brain damage due to decreased oxygen supply when blood pressure is low.

additionally, in the context of administering emergency treatments such as epinephrine, the supine position can facilitate easier access for intramuscular injections. most emergency treatments for severe allergic reactions involve injections, often administered in the thigh. lying supine allows responders clear access to administer treatment quickly and effectively.

conversely, other positions like sitting upright, prone, or on the side are less ideal for unconscious patients suffering from allergic reactions. sitting upright can exacerbate circulatory issues by pooling blood in the lower extremities, reducing effective blood flow to the brain and heart. the prone position can complicate breathing and airway management, while lying on the side, though sometimes recommended for unconscious patients who are vomiting or at risk of aspiration, is not optimal for those with severe allergic reactions where airway and circulatory support are priorities.

in conclusion, the supine position is the safest and most effective way to manage a patient who is unconscious due to an allergic reaction. it ensures an open airway, promotes better blood circulation, and facilitates emergency medical interventions. it is a fundamental aspect of first aid and emergency response in such medical scenarios.

If etchant is accidently spilled, it should be:

Correct Answer:
cleaned up immediately with water.

when etchant is accidentally spilled, the appropriate response is to clean it up immediately using a substantial amount of water. this prompt action is crucial because etchants, which are typically acidic or basic chemical solutions used in various manufacturing and laboratory processes, can rapidly corrode materials and harm skin or other organic tissues upon contact.

the reason why water is recommended for cleaning up etchant spills, rather than other cleaning agents like soap or using methods such as vacuuming or air drying, is based on the chemical properties of etchants. water dilutes the etchant, reducing its concentration and thereby mitigating its corrosive effects. this makes the spill safer to manage and lessens the potential for damage or injury.

using soap might not be advisable as certain soaps can react chemically with the etchant, potentially creating more harmful or volatile compounds. vacuuming up a liquid etchant is not only ineffective but also dangerous, as it can spread the corrosive fumes or even damage the vacuum cleaner. allowing the etchant to air dry is equally hazardous because it does not remove the chemical. instead, it could lead to the formation of concentrated residue that can cause severe damage to surfaces and health risks upon contact.

immediate cleanup with copious amounts of water ensures that the etchant is sufficiently diluted and can be safely handled and disposed of according to the specific guidelines for hazardous waste. such quick and appropriate handling of spills not only protects personnel from chemical burns and other injuries but also minimizes damage to equipment, work surfaces, and the environment. therefore, knowing and following the correct spill response procedures is essential in settings where etchants are used.
