MPOETC Emergency Response and CPR Questions and Answers — Questions and Answers
Question 1: 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?
- Check for a medical alert bracelet.
- Immediately begin high-quality chest compressions. (Correct answer)
- Deliver two initial rescue breaths.
- Apply an AED and wait for it to analyze.
Correct 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.
Question 2: 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?
- Elevate the arm above the victim's heart.
- Apply pressure to the brachial artery pressure point.
- Apply a commercially-made tourniquet 2-3 inches proximal to the wound (closer to the torso). (Correct answer)
- Cover the wound with more gauze and wait for EMS to arrive.
Correct 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.
Question 3: 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?
- Flushed red skin, slow pulse, and high blood pressure.
- Rapid, bounding pulse, warm skin, and normal breathing.
- Pale/cool skin, rapid/weak pulse, and rapid/shallow breathing. (Correct answer)
- Slow, shallow breathing, constricted pupils, and low body temperature.
Correct 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.
Question 4: 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?
- Cardiac Arrest
- Diabetic Emergency
- Opioid Overdose (Correct answer)
- Severe Allergic Reaction
Correct 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).
Question 5: When performing single-rescuer CPR on an adult, what is the correct and universally accepted ratio of chest compressions to rescue breaths?
- 15 compressions to 2 breaths
- 30 compressions to 1 breath
- 15 compressions to 1 breath
- 30 compressions to 2 breaths (Correct answer)
Correct 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.
Question 6: 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?
- Expressed Consent
- Implied Consent (Correct answer)
- The Good Samaritan Act
- Informed Consent
Correct 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.
