Emergency Response and CPR Flashcards

An officer arrives on scene to find an adult male who is unresponsive, pulseless, and not breathing. After ensuring the scene is safe, what is the officer's most critical and immediate action according to current CPR guidelines?

Answer: Immediately begin high-quality chest compressions.

According to the American Heart Association guidelines, the most critical initial action for an adult in cardiac arrest is to start high-quality chest compressions with minimal delay. The C-A-B (Compressions, Airway, Breathing) sequence prioritizes circulating existing oxygenated blood to the vital organs.

While rendering aid at a vehicle crash, an officer encounters a victim with a severe, spurting arterial bleed from the upper arm. Direct pressure with gauze is not controlling the hemorrhage. What is the most appropriate next step?

Answer: Apply a commercially-made tourniquet 2-3 inches proximal to the wound (closer to the torso).

For life-threatening extremity hemorrhage that is not controlled by direct pressure, the standard of care is the immediate application of a tourniquet. It should be placed 2-3 inches above the wound, between the wound and the heart, and not on a joint.

An officer is assessing a victim who was involved in a serious assault. Which of the following sets of signs and symptoms is most indicative of the victim going into hypovolemic shock?

Answer: Pale/cool skin, rapid/weak pulse, and rapid/shallow breathing.

Hypovolemic shock is characterized by the body's response to fluid or blood loss. This includes a rapid, weak pulse as the heart tries to compensate; cool, pale, clammy skin due to peripheral vasoconstriction; and rapid, shallow breathing to increase oxygen intake.

An officer finds an unconscious person at a bus stop. The person is breathing very slowly and shallowly (agonal breathing), has pinpoint pupils, and there is drug paraphernalia nearby. Based on these classic signs, the officer should primarily suspect and be prepared to treat which condition?

Answer: Opioid Overdose

The combination of respiratory depression (slow, shallow breathing), pinpoint pupils, and decreased level of consciousness forms the classic 'opioid overdose triad.' The presence of paraphernalia further supports this assessment, indicating the potential need for Naloxone (Narcan).

When performing single-rescuer CPR on an adult, what is the correct and universally accepted ratio of chest compressions to rescue breaths?

Answer: 30 compressions to 2 breaths

The American Heart Association and other international resuscitation councils recommend a universal compression-to-ventilation ratio of 30 compressions to 2 breaths for a single rescuer performing CPR on an adult victim.

An officer arrives at the scene of a fall and finds an elderly person unconscious and in clear need of immediate medical aid. The person is alone and cannot give permission for treatment. Under which legal principle can the officer begin to render emergency first aid?

Answer: Implied Consent

Implied consent is a legal principle that assumes a person who is unable to give consent (due to being unconscious, incapacitated, or otherwise unable to respond) would agree to receive life-saving medical care if they were able to. This allows first responders to act without delay in a medical emergency.
