This technique may be useful for larger infants or when the BLS provider has difficulty compressing the appropriate depth. - Correct Ans-The Heel of One Hand technique You and another BLS provider are giving CPR to a 7-year-old child when the AED arrives. You turn on the AED, switch the AED to pediatric energy levels, and apply the pads. The other BLS provider should: - Correct Ans-BLS provider should continue high-quality compressions while the AED is charging When breathing slows or stops, it leads to bradycardia, a slow heart rhythm of fewer than _ beats per minute. - Correct Ans-60 You are a lone BLS provider responding to a possible adult cardiac arrest. The scene is safe. You have taken standard precautions. An untrained bystander heard the person collapse. You have activated EMS or your occupational emergency action plan. Other providers are on the way. An AED is located in the building, about 3 minutes away. The patient is unresponsive and making gurgling sounds. You do not feel a carotid pulse. You have a CPR mask with a one-way valve. What should you do? - Correct Ans-Send the bystander to get the AED. Start high-quality CPR. You and another BLS provider have responded to a call for a 5-month-old infant with trouble breathing. The scene is safe. You have taken standard precautions. The infant is unresponsive and gasping. You have activated EMS or your occupational emergency action plan. A weak brachial pulse at about 40 beats per minute is felt. The infant's skin is mottled, and the hands and feet are cool to touch. Other BLS providers are a few minutes away with an AED. What should you do? - Correct Ans-You should start high-quality CPR You are attempting to resuscitate an unresponsive 25-year-old who overdosed on fentanyl. The scene is safe. You have taken standard precautions. EMS or your occupational emergency action plan has been activated. The patient is making snorting sounds. The carotid pulse is definitely felt. You have a bag-mask device, AED, and Narcan Nasal Spray. What should you do? - Correct Ans-Ventilate the patient and give naloxone per local medical protocol. Early recognition of cardiac arrest and prompt activation of EMS is which link in the adult Out-of-Hospital chain of survival? - Correct Ans-Activation of Emergency Response Allow ________________ between chest compressions so the heart can refill. - Correct Ans-Complete chest recoil When assessing an unresponsive adult, child, or infant, you should take no longer than ___ seconds to simultaneously assess breathing and pulse. - Correct Ans-10 seconds - To minimize interruption in chest compression when assessing an unresponsive adult, child, or infant, you should take no longer than 10 seconds to simultaneously assess breathing and pulse. The first link in the out-of-hospital pediatric cardiac arrest chain of survival is: - Correct Ans-Preventing causes of respiratory failure or respiratory arrest, which lead to cardiac arrest. When ventilating a child with a bag-mask device, give 1 breath every 2-3 seconds. Deliver each breath over ____ second(s) in length while watching for chest rise. - Correct Ans-1 second - When ventilating a child with a bag-mask device, deliver each breath over 1 second in length while watching for chest rise. To locate the brachial pulse on an infant, place two or three fingers: - Correct Ans-inside of the upper arm, midway between the elbow and shoulder. You are the only BLS provider responding to "baby not breathing." The scene is safe, and you have taken standard precautions. The infant is unresponsive. You have activated EMS or your occupational emergency action plan. Other providers are on the way with an AED. You do not feel a brachial pulse. What should you do? - Correct Ans-Immediately start high-quality CPR, beginning with chest compressions. You are using a bag-mask device to ventilate a 16-year-old in cardiac arrest who suddenly collapsed. An endotracheal tube has been placed by an advanced life support provider on the resuscitation team. Proper ventilation technique in the situation requires that you: - Correct Ans-Squeeze the bag to deliver 1 breath every 6 seconds. When chest compressions stop, blood flow ___________significantly. - Correct Ans-decreases You are the only BLS provider responding to witnessed collapse of a 11-year-old child during a softball game. The scene is safe, and you have taken standard precautions. The patient is unresponsive and gasping occasionally. You do not feel a carotid pulse and an AED is within sight. What should you do? - Correct Ans-Activate EMS or your occupational emergency action plan and get the AED. Supporting a patient's physical and emotional needs that are ongoing after hospital discharge is which link in the chain of survival? - Correct Ans-Recovery Your adult patient is making abnormal gasping, snoring sounds. You definitely feel a carotid pulse. What should you do? - Correct Ans-Provide rescue breathing or bag-mask ventilation. To open the airway with a jaw thrust, position yourself: - Correct Ans-Above the patient's head. Which link in the out-of-hospital adult chain of survival is critical to survival when a patient's heart is in an abnormal rhythm like pulseless ventricular tachycardia (VT) and ventricular fibrillation (VF)? - Correct Ans-Defibrillation You are a lone BLS provider responding to a possible cardiac arrest. The scene is safe, and you have taken standard precautions. The patient is unresponsive. You have activated EMS or your occupational emergency action plan. Other providers are on the way and you have an AED. The patient is occasionally gasping. You do not feel a carotid pulse. What should you do? - Correct Ans-Power on the AED. Apply adult pads to patient's bare chest.
