ADAP Dental Emergencies and First Aid 1 — Questions and Answers
Question 1: What is the FIRST action a dental assistant should take when a patient experiences syncope (fainting) in the dental chair?
- Administer oxygen immediately
- Lower the chair to a supine position with legs elevated (Correct answer)
- Call 911 right away
- Give the patient a glass of water
Correct answer: Lower the chair to a supine position with legs elevated
Placing the patient supine with legs elevated improves cerebral blood flow, which is the primary treatment for vasovagal syncope.
Question 2: Which drug is the MOST critical emergency medication to have available in the dental office for treating anaphylaxis?
- Nitroglycerin
- Epinephrine (adrenaline) (Correct answer)
- Diphenhydramine (Benadryl)
- Aspirin
Correct answer: Epinephrine (adrenaline)
Epinephrine is the first-line treatment for anaphylaxis because it reverses bronchoconstriction and vasodilation through adrenergic receptor stimulation.
Question 3: A patient suddenly develops chest pain radiating to the left arm and jaw during a dental procedure. Which emergency is MOST likely occurring?
- Panic attack
- Hyperventilation syndrome
- Myocardial infarction (Correct answer)
- Postural hypotension
Correct answer: Myocardial infarction
Chest pain radiating to the left arm and jaw is a classic presentation of myocardial infarction (heart attack) and requires immediate emergency response.
Question 4: What is the NORMAL resting adult respiratory rate range that a dental assistant should know when assessing a patient?
- 6–10 breaths per minute
- 12–20 breaths per minute (Correct answer)
- 22–28 breaths per minute
- 30–36 breaths per minute
Correct answer: 12–20 breaths per minute
A normal adult respiratory rate at rest is 12–20 breaths per minute; values outside this range indicate a potential emergency.
Question 5: A diabetic patient becomes shaky, sweaty, and confused during treatment. What is the FIRST intervention?
- Administer insulin immediately
- Give oral glucose such as orange juice or glucose gel (Correct answer)
- Call 911 before doing anything else
- Have the patient breathe into a paper bag
Correct answer: Give oral glucose such as orange juice or glucose gel
These symptoms indicate hypoglycemia; administering a fast-acting carbohydrate source raises blood sugar quickly in a conscious patient.
Question 6: During a dental appointment, a patient suddenly has a tonic-clonic (grand mal) seizure. What should the dental team do FIRST?
- Insert a bite block to protect the airway
- Restrain the patient to prevent injury
- Clear the area of hard objects and protect the patient's head (Correct answer)
- Administer oxygen via mask immediately
Correct answer: Clear the area of hard objects and protect the patient's head
The priority during an active seizure is to prevent injury by clearing hazards and cushioning the head; restraint can cause fractures and objects should never be placed in the mouth.
Question 7: Which vital sign reading in an adult dental patient would indicate a hypertensive emergency requiring immediate attention?
- 120/80 mmHg
- 140/90 mmHg
- 160/100 mmHg
- 180/120 mmHg or higher (Correct answer)
Correct answer: 180/120 mmHg or higher
A blood pressure of 180/120 mmHg or higher is classified as a hypertensive crisis requiring immediate medical evaluation before dental treatment proceeds.
