Correct Ans- respiratory failure or shock What is cardiac arrest? Correct Ans- occurs when the heart develops an abnormal rhythm and stops beating or beats too ineffectively to circulate blood to the brain and other vital organs What is heart attack? Correct Ans- A blockage of blood flow to the heart muscle. List the eight components of high quality CPR. Correct Ans- 1. Start compressions within 10 seconds of recognition of cardiac arrest. 2. Compress at a rate of 100-120/min with a depth of at least 2 inches in adults/children and 1 1/2 inches in infants. 3. Allow complete chest recoil after each compression. 4. Minimize interruptions in compressions (limit to <10 seconds). 5. Give effective breaths that make the chest visibly rise. 6. Switch compressors about every 2 minutes or earlier if fatigued. 7. Continue delivering chest compressions while the AED is charging. 8. Avoid prolonged rhythm analysis, frequent or inappropriate pulse checks, taking too long to give breaths to the patient, excessive ventilation, or unnecessarily moving the patient. What is the recommended compression depth for adults and children? Correct Ans- 2 inches What is the recommended compression depth for infants? Correct Ans- 1 1/2 inches What can result if a patient is ventilated too quickly? Correct Ans- hyperventilation -> excessive intrathoracic pressure and gastric inflation -> decreased venous return -> decreased coronary and cerebral perfusion pressures -> diminished cardiac output -> decreased rates of survival What memory aid may be used when evaluating a patient's level of consciousness? Correct Ans- AVPU Alert, responds to Verbal stimuli, responds to Painful stimuli, Unresponsive Upon finding an unresponsive adult patient, you verified that the scene is safe, called for help and asked that someone get an AED or defibrillator.

Your next action should be to: Correct Ans- begin chest compressions 30:2 (1 rescuer), 15:2 (2 rescuer); if 2 rescuers are present, one rescuer begins CPR and the other activates the ERS; use the AED as soon as it arrives; after about 2 min of CPR, if you are still alone, activate the ERS and get the AED if not already done Upon finding an unresponsive infant or child, you verified that the scene is safe, called for help and asked that someone get an AED or defibrillator. You check for breathing and a carotid pulse simultaneously. The patient has no pulse and is not breathing normally. The arrest was sudden and witnessed. Your next action should be to: Correct Ans- activate the emergency response system and retrieve the AED; begin chest compressions 30:2 (1 rescuer), 15:2 (2 rescuer) Upon finding an unresponsive infant or child, you verified that the scene is safe, called for help and asked that someone get an AED or defibrillator. You check for breathing and a carotid pulse simultaneously. The patient is breathing normally and a pulse is present. Your next action should be to: Correct Ans- activate ERS, return to victim and monitor until emergency responders arrive Upon finding an unresponsive adult patient, you verified that the scene is safe, called for help and asked that someone get an AED or defibrillator. You check for breathing and a carotid pulse simultaneously. The patient is not breathing normally but a pulse is present. Your next action should be to: Correct Ans- provide rescue breathing (one breath every 5-6 seconds) and recheck for a pulse every 2 minutes; be ready to perform high quality CPR if you do not feel a pulse; if opioid use is suspected, consider administering naloxone Upon finding an unresponsive infant or child, you verified that the scene is safe, called for help and asked that someone get an AED or defibrillator. You check for breathing and a carotid pulse simultaneously. The patient is not breathing normally but a pulse is present. Your next action should be to: Correct Ans- provide rescue breathing (one every 3-5 seconds); add compressions if pulse remains <60/min with signs of poor perfusion; activate ERS after 2 min; continue rescue breathing and check pulse about every 2 min (if no pulse begin CPR) What is the purpose of the primary survey?

Correct Ans- 60-80% What is the appropriate tidal volume for adult cardiac arrest patients? Correct Ans- 500-600 mL (half a squeeze of an adult ventilation bag; enough to see visible chest rise) Single rescuers should use the compression-to-ventilation ratio of ____ compressions to ____ breaths when giving CPR to victims of any age. Correct Ans- 30:2 At what rate should compressions occur? Correct Ans- 100-120/min Interruptions in chest compressions should be limited to how many seconds? Correct Ans- <10 Rescuers should switch compressors how often? Correct Ans- every 5 cycles (2 min) or sooner if fatigued What method should be utilized when opening the airway of a patient who is suspected of having a head or neck injury? Correct Ans- jaw thrust When communicating with a team member, the team leader communicates by taking these steps: 1. The team leader gives a message, order, or assignment to a team member. 2.

What is the first action you should take in this situation? Correct Ans- verify that the scene is safe for you and the victim A 53-year-old man suddenly collapses and becomes unresponsive. You witness him collapse and are the first rescuer to arrive at the scene. You find him lying motionless on the floor. The man doesn't respond when you touch his shoulder and shout, "Are you OK?" What is your best next action? Correct Ans- check for breathing and carotid pulse; shout for nearby help A 53-year-old man suddenly collapses and becomes unresponsive. You witness him collapse and are the first rescuer to arrive at the scene. You find him lying motionless on the floor. Several rescuers respond, and you ask them to activate the emergency response and retrieve the AED and emergency equipment. As you check for a pulse and breathing, you notice that the man is gasping for air and making "snorting" sounds. You do not feel a pulse. What is your best next action? Correct Ans- start high-quality CPR, beginning with chest compressions How does one properly use an AED? Correct Ans- 1. Open the carrying case and power on the AED. 2. Attach AED pads to the victim's bare chest. 3. When the AED prompts you, clear the victim and allow the AED to analyze the rhythm. 4. Resume chest compressions while the AED is charging. 5. Clear the victim when delivering a shock; resume compressions after the shock has been delivered. 6. If no shock is needed, immediately resume CPR starting with chest compressions. What are the two correct methods for placement of AED pads? Correct Ans- Method 1. AKA Anterolateral Placement. Place one AED pad directly below the right collarbone. Place the other pad to the right side of the left nipple, with the top edge of the pad a few inches below the arm pit. Method 2. AKA Anteroposterior Placement. Place one AED pad on the left side of the chest, between the victim's left side of the breastbone and left nipple. Place the other pad on the left side of the victim's back, next to the spine. When placing AED pads on a patient with an implanted defibrillator or pacemaker, what precautions should be taken? Correct Ans- avoid placing AED pad directly over the implanted device What is the most appropriate first step to take as soon as the AED arrives at the victim's side? Correct Ans- power on the AED What action should you take when the AED is analyzing the heart rhythm? Correct Ans- stand clear of the victim How does one properly palpate a brachial pulse on an infant? Correct Ans- 1. Place 2-3 fingers on the inside of the upper arm, midway between the elbow and the shoulder. 2. Then press the fingers to attempt to feel the pulse for at least 5 seconds but no more than 10 seconds. How does one properly palpate a femoral pulse on a child? Correct Ans- 1. Place 2 fingers in the inner thigh, midway between the hipbone and the pubic bone and just below the crease where the leg meets the torso. 2.

Correct Ans- femoral or carotid What is the correct hand placement for performing high-quality chest compressions on a child? Correct Ans- 2 hands or 1 hand (optional for small child) on the lower half of the sternum What is the correct hand placement for performing high-quality chest compressions on an infant? Correct Ans- 1 rescuer: 2 fingers in the center of the chest, just below the nipple line 2 or more rescuers: 2 thumb-encircling hands in the center of the chest, just below the nipple line What are some signs of poor perfusion? Correct Ans- cool extremities, altered mental status, weak pulses, pale skin, mottling, cyanosis What is the correct compression ratio for children and infants when two rescuers are present? Correct Ans- 15:2 How does one properly perform 2 finger compression technique on an infant? Correct Ans- 1. Place the infant on a firm, flat surface. 2. Place 2 fingers in the center of the infant's chest, just below the nipple line, on the lower half of the breastbone. 3. Give compressions at a rate of 100-120/min. 4. Compress at least one third the AP diameter of the infant's chest (about 1 1/2 in). 5. Allow for complete chest recoil. Minimize interruptions to less than 10 seconds. 6. After every 30 compressions, open the airway using head tilt-chin lift method and deliver two breaths. 7. After about 5 cycles (2 min) of CPR, if you are alone and the ERS has not been activated, leave the infant (or carry the infant with you) and activate the ERS and retrieve the AED. 8. Continue compressions and breaths at 30:2 ratio and use the AED as soon as it arrives. Continue until advanced providers take over or the infant begins breathing or moving. How does one properly perform 2 thumb-encircling hands technique on an infant? Correct Ans- 1. Place the infant on a firm, flat surface. 2. Place both thumbs side by side in the center of the infant's chest, on the lower half of the breastbone. Thumbs may overlap in small infants. 3. With your hands encircling the chest, use both thumbs to depress the breastbone at a rate of 100-120/min. 4. Compress at least one third the AP diameter of the infant's chest (about 1 1/2 in). 5. After each compression, completely release the pressure on the breastbone and allow the chest to recoil completely. 6. After every 15 compressions, pause briefly for the second rescuer to open the airway with a head tilt-chin lift and give 2 breaths, each over 1 sec. 7. Continue compressions and breaths in a ratio of 15:2 (2 rescuer). The rescuer providing chest compressions should switch roles with another provider about every 5 cycles (2 min). Continue CPR until the AED arrives, advanced providers take over, or the infant begins to breath/move. Why is it important to ensure that the infant's head is kept in the neutral position? Correct Ans- if you tilt (extend) an infant's head beyond the neutral (sniffling) position, the infant's airway may become blocked; you should ensure the infant's neck is in a neutral position so that the external ear canal is level with the top of the infant's shoulder What is the correct compression-to-ventilation ratio for a single rescuer of a 3-year-old child? Correct Ans- 30:2 What is the correct compression-to-ventilation ratio for a 7-year-old child when 2 rescuers or more are present? Correct Ans- 15:2 Adult pads should be used on what age victim? Correct Ans- 8 years and older; may use them on infants if you do not have child pads What are two ways to open the victim's airway? Correct Ans- head tilt-chin lift and jaw thrust If the chest does not rise when you give a breath, what should you do?
