CCMA Emergency Management and First Aid

Question 1

What is the correct compression-to-ventilation ratio for single-rescuer adult CPR according to current AHA guidelines?

Accepted Answer

30:2

Answer

The American Heart Association recommends 30 chest compressions followed by 2 rescue breaths (30:2) for single-rescuer adult CPR. This ratio maximizes coronary perfusion pressure between compressions.

Question 2

A patient in the waiting room collapses and is unresponsive. After activating the emergency response system, what is the NEXT immediate action?

Accepted Answer

Check for breathing and a pulse for no more than 10 seconds

Answer

Before initiating CPR, you must quickly assess for breathing and a pulse (no longer than 10 seconds). This assessment determines whether CPR, AED use, or another intervention is needed. Assessment always precedes intervention.

Question 3

Which type of shock results from a severe systemic allergic reaction and is characterized by widespread vasodilation and hypotension?

Accepted Answer

Anaphylactic shock

Answer

Anaphylactic shock occurs when massive IgE-mediated release of histamine and other mediators causes vasodilation, increased vascular permeability, and a life-threatening drop in blood pressure. Epinephrine is the first-line treatment.

Question 4

An AED is attached to an unresponsive patient with no pulse. The device announces 'No shock advised.' What should the medical assistant do immediately?

Accepted Answer

Resume CPR immediately

Answer

A 'no shock advised' message means the rhythm is non-shockable (e.g., asystole or pulseless electrical activity). CPR must be resumed immediately, as defibrillation will not help and circulation must be maintained manually.

Question 5

A conscious adult patient is choking, cannot speak, and cannot cough. Which intervention should the medical assistant perform?

Accepted Answer

Perform abdominal thrusts (Heimlich maneuver)

Answer

A complete airway obstruction in a conscious adult (unable to speak, cough, or breathe) requires immediate abdominal thrusts (Heimlich maneuver) to create enough pressure to expel the foreign body. Back blows are used for infants.
