What is the recommended depth of chest compressions for adult CPR according to current AHA guidelines?
Answer: At least 2 inches (5 cm), not exceeding 2.4 inches (6 cm)
AHA guidelines specify adult chest compressions should be at least 2 inches deep but no more than 2.4 inches to maximize perfusion while avoiding injury.
A conscious patient who ingested an overdose of local anesthetic begins experiencing perioral numbness and metallic taste. These are signs of toxicity affecting which system first?
Answer: Central nervous system
CNS toxicity from local anesthetic overdose manifests first with perioral numbness, tinnitus, metallic taste, and agitation before progressing to cardiovascular collapse.
Which position is recommended for a pregnant patient who becomes hypotensive in the dental chair?
Answer: Left lateral tilt (15-30 degrees)
Left lateral tilt displaces the gravid uterus off the inferior vena cava, relieving supine hypotensive syndrome by restoring venous return in the third trimester.
A patient with a history of adrenal insufficiency is undergoing a lengthy, stressful procedure. Which emergency is this patient at risk for?
Answer: Addisonian (adrenal) crisis
Patients with adrenal insufficiency cannot produce adequate cortisol in response to surgical stress, potentially triggering an Addisonian crisis with profound hypotension.
The dental emergency kit should contain which of the following for management of hypoglycemia in a conscious patient?
Answer: Oral glucose gel or orange juice
A conscious patient who can swallow should receive oral glucose (gel, juice, or glucose tablets) as the safest and most practical first-line treatment for hypoglycemia.
During a medical emergency requiring 100% oxygen delivery, which delivery device provides the highest oxygen concentration?
Answer: Non-rebreather mask at 15 L/min
A non-rebreather mask with a reservoir bag at 15 L/min delivers approximately 90-100% FiO2, making it the highest concentration non-invasive delivery device.
Which of the following best describes the 'chain of survival' concept in cardiac emergency response?
Answer: Call 911 → CPR → defibrillation → advanced life support → post-arrest care
The AHA chain of survival links early recognition/activation of EMS, early CPR, rapid defibrillation, advanced life support, and post-cardiac arrest care as sequential survival-improving steps.
