MPOETC First Aid & Emergency Medical Care — Questions and Answers
Question 1: An officer arrives at a scene where an adult male is unresponsive and not breathing normally. After confirming scene safety, the officer's immediate priority should be:
- Establishing a perimeter and waiting for EMS to arrive with proper equipment
- Contacting the victim's next of kin to obtain medical history
- Beginning CPR immediately and deploying or requesting an AED (Correct answer)
- Rolling the victim into the recovery position to prevent aspiration
Correct answer: Beginning CPR immediately and deploying or requesting an AED
For an unresponsive victim not breathing normally, immediate CPR and rapid defibrillation are the two interventions most likely to save the victim's life. Brain death begins within 4–6 minutes of cardiac arrest, and survival rates drop roughly 10% per minute without defibrillation. Officers certified in CPR must act immediately rather than wait for EMS.
Question 2: An officer encounters a gunshot victim with severe, uncontrolled bleeding from the upper thigh. After securing the scene, the officer should:
- Elevate the leg and apply a clean cloth with direct pressure while waiting for EMS
- Apply a tourniquet 2–3 inches above the wound site and note the time of application (Correct answer)
- Pack the wound tightly with gauze, then apply direct pressure for at least 10 minutes
- Leave the wound undisturbed to avoid dislodging any clots that may have formed
Correct answer: Apply a tourniquet 2–3 inches above the wound site and note the time of application
For severe, uncontrolled extremity hemorrhage, current tactical emergency casualty care (TECC) and 'Stop the Bleed' protocols taught in MPOETC training direct officers to apply a commercial tourniquet 2–3 inches above the wound. Marking the time of application is critical so medical personnel know how long blood flow has been restricted. Direct pressure alone is insufficient for major arterial bleeding.
Question 3: An officer finds a person unconscious and cyanotic (bluish skin), with extremely slow breathing and pinpoint pupils. A bystander says the person 'used something.' The officer has naloxone available. The officer should:
- Wait to confirm the substance before administering naloxone to avoid a dangerous drug interaction
- Administer naloxone based on the clinical signs consistent with opioid overdose (Correct answer)
- Administer naloxone only if the victim has a known history of opioid use
- Administer naloxone only after attempting CPR for at least 2 minutes
Correct answer: Administer naloxone based on the clinical signs consistent with opioid overdose
Naloxone should be administered based on clinical presentation — slow breathing, pinpoint pupils, and decreased consciousness — not confirmed substance identity. In a suspected overdose, waiting to confirm the drug wastes critical time. Pennsylvania's Act 139 of 2014 provides legal immunity for officers who administer naloxone in good faith based on signs of opioid overdose.
Question 4: Pennsylvania's Act 139 of 2014 provides that law enforcement officers who administer naloxone in good faith to a person experiencing a suspected opioid overdose are:
- Protected by immunity from civil and criminal liability (Correct answer)
- Required to obtain informed consent from the victim or family members before administration
- Liable only if they failed to complete a formal EMS certification course
- Required to document the administration and submit to a formal review by the department medical officer
Correct answer: Protected by immunity from civil and criminal liability
Act 139 grants civil and criminal immunity to law enforcement officers, first responders, and laypersons who administer naloxone in good faith to someone experiencing or suspected of experiencing an opioid overdose. This immunity provision was enacted specifically to remove barriers to intervention during Pennsylvania's opioid crisis.
Question 5: When applying a tourniquet to control severe limb hemorrhage, the device should be placed:
- Directly over the wound to apply maximum direct pressure
- 2–3 inches above (proximal to) the wound on the limb (Correct answer)
- Below the wound to preserve blood flow to the injury and prevent tissue death
- As close to the armpit or groin as possible, regardless of wound location
Correct answer: 2–3 inches above (proximal to) the wound on the limb
A tourniquet works by compressing the blood vessels proximal (above) the wound, cutting off blood flow to the injury site. Placing it 2–3 inches above the wound is the recommended distance — close enough to restrict flow effectively but not directly over the wound where placement may be mechanically ineffective. Placement below the wound would have no effect on hemorrhage control.
Question 6: A victim is found with an altered level of consciousness after a motor vehicle crash. The officer suspects a possible spinal injury. The officer should:
- Move the victim to the sidewalk immediately to clear the road for oncoming traffic
- Roll the victim onto their side to open the airway and prevent aspiration
- Minimize movement of the head and neck and maintain manual spinal stabilization until EMS arrives (Correct answer)
- Perform a full neurological assessment by checking grip strength and leg movement
Correct answer: Minimize movement of the head and neck and maintain manual spinal stabilization until EMS arrives
The spinal cord cannot regenerate — an unstable spinal fracture that is moved inappropriately can cause or worsen permanent paralysis. Officers should minimize movement of the head, neck, and spine and maintain manual in-line stabilization until EMS arrives with proper immobilization equipment. The exception is immediate life threat (fire, drowning), where the risk of movement is outweighed by the danger of remaining in place.
