Question 1

The first drug administered during pulseless ventricular fibrillation (VF) cardiac arrest, following defibrillation, is:

Accepted Answer

Epinephrine 1 mg IV every 3 to 5 minutes

Answer

After the first defibrillation attempt, ACLS guidelines call for epinephrine 1 mg IV/IO every 3 to 5 minutes during ongoing CPR.

Question 2

Diphenhydramine (Benadryl) is used in anaphylaxis management primarily to:

Accepted Answer

Block H1 receptors and reduce urticaria and pruritus

Answer

Diphenhydramine is an H1 antihistamine that reduces urticaria, pruritus, and nasal symptoms. It is a secondary medication in anaphylaxis; epinephrine is primary.

Question 3

When administering epinephrine for anaphylaxis in the dental office, the preferred route is:

Accepted Answer

Intramuscular injection into the anterolateral thigh

Answer

IM injection into the vastus lateralis (anterolateral thigh) provides the most reliable, rapid absorption of epinephrine during anaphylaxis.

Question 4

Glucagon is used to treat refractory hypotension in anaphylaxis for patients who are:

Accepted Answer

On beta-blockers, which blunt the response to epinephrine

Answer

Patients on beta-blockers may not respond adequately to epinephrine since beta-adrenergic effects are blocked. Glucagon increases cAMP independently of beta receptors.

Question 5

The recommended compression-to-ventilation ratio during two-rescuer adult CPR is:

Accepted Answer

30:2

Answer

AHA guidelines recommend 30 compressions to 2 ventilations for adults in two-rescuer CPR when an advanced airway is not in place.
