CDC Emergency Procedures & Response 3

Question 1

A patient develops sudden chest pain, diaphoresis, and jaw pain during a dental appointment. What is the most likely diagnosis?

Accepted Answer

Acute myocardial infarction

Answer

Chest pain with diaphoresis and jaw pain are classic signs of acute myocardial infarction requiring immediate 911 activation.

Question 2

Which position is most appropriate for a patient experiencing anaphylactic shock in the dental office?

Accepted Answer

Supine with legs elevated (Trendelenburg)

Answer

Supine position with legs elevated increases venous return and maintains cerebral perfusion in anaphylactic shock.

Question 3

During administration of local anesthesia, a patient reports ringing in the ears and a metallic taste. These are signs of:

Accepted Answer

Local anesthetic systemic toxicity (LAST)

Answer

Tinnitus and metallic taste are early CNS warning signs of local anesthetic systemic toxicity due to elevated plasma drug levels.

Question 4

A patient with asthma experiences bronchospasm in the dental chair unrelieved by their own inhaler. What is the next step?

Accepted Answer

Administer epinephrine 1:1,000 IM and activate EMS

Answer

Severe bronchospasm unresponsive to the patient's own bronchodilator requires IM epinephrine and immediate EMS activation.

Question 5

An automated external defibrillator (AED) analyzes a rhythm and advises 'no shock recommended.' What should the responder do?

Accepted Answer

Immediately resume CPR

Answer

When the AED advises no shock, CPR should be resumed immediately as the rhythm may be a non-shockable arrest (PEA or asystole).
