Once the AED delivers a shock, what is the next most important step for the rescuer? (page 26)
- A.
Analyze the rhythm again
- B.
Resume chest compressions
- C.
Deliver 2 rescue breaths
- D.
Remove the AED pads
Correct Answer
B. Resume chest compressionsExplanation
After delivering a shock with the AED, the next most important step for the rescuer is to resume chest compressions. This is because chest compressions are crucial for maintaining blood flow and oxygenation to the vital organs, especially the brain. By immediately resuming chest compressions, the rescuer can continue to provide circulation until further interventions or medical help arrive. Analyzing the rhythm again, delivering rescue breaths, and removing the AED pads are important steps, but they should be done after resuming chest compressions.Rate this question:

What is the compression to ventilation ratio for one rescuer BLS? (page 10)
- A.
15:2
- B.
30:2
- C.
100:2
- D.
3:1
Correct Answer
B. 30:2Explanation
The compression to ventilation ratio for one rescuer BLS is 30:2. This means that for every 30 compressions, there should be 2 ventilations. This ratio is important in maintaining adequate blood flow and oxygenation during CPR. By providing a higher number of compressions before ventilations, it maximizes the chances of circulating oxygenated blood to the vital organs and improves the chances of successful resuscitation.Rate this question:

Which of the following describes the proper sequence of steps in BLS? (Pages 8-10)
- A.
Call for help, check responsiveness, deliver breaths
- B.
Check responsiveness, call for help, apply AED
- C.
Check pulse, call for help, begin compressions
- D.
Scene safety, check responsiveness, call for help
Correct Answer
D. Scene safety, check responsiveness, call for helpExplanation
The proper sequence of steps in BLS (Basic Life Support) is to ensure scene safety first, then check for responsiveness of the victim, and finally call for help. This sequence ensures that the rescuer is in a safe environment before attempting to provide assistance, and then assesses the victim's level of consciousness. Once the rescuer has determined that the victim is unresponsive, they should immediately call for additional help.Rate this question:

When there is more than one rescuer available at the scene of a cardiac arrest, how often should they rotate their roles as compressors/ventilators? (page 15)
- A.
Every 2 minutes
- B.
Every 5 minutes
- C.
After every cycle of 30 compressions
- D.
After each pulse check
Correct Answer
A. Every 2 minutesExplanation
When there is more than one rescuer available at the scene of a cardiac arrest, they should rotate their roles as compressors/ventilators every 2 minutes. This ensures that each rescuer gets a chance to perform both tasks and prevents fatigue. Regular rotation also helps maintain the quality and effectiveness of CPR by allowing rescuers to switch positions and provide fresh energy.Rate this question:

Adult sized AED pads can be used on an infant if no pediatric pads or a pediatric capable AED is available. (page 41)
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Adult sized AED pads can be used on an infant if no pediatric pads or a pediatric capable AED is available. This means that in a situation where an infant needs immediate defibrillation and there are no specific pediatric pads or equipment, using adult sized pads on the infant is acceptable. This is because the adult pads can still deliver the necessary shock to the infant's body. However, it is important to note that using pediatric pads or a pediatric capable AED is always the preferred and recommended method for treating infants in cardiac arrest.Rate this question:

What is the correct course of action for a responsive person with a mild foreign body airway obstruction who is able to cough? (page 51)
- A.
Smack them on the back
- B.
Perform abdominal thrusts
- C.
Monitor their condition
- D.
Do chest compressions
Correct Answer
C. Monitor their conditionExplanation
The correct course of action for a responsive person with a mild foreign body airway obstruction who is able to cough is to monitor their condition. This means keeping a close eye on the person to ensure that their condition does not worsen. If they are able to cough, it indicates that their airway is partially open and they are able to clear the obstruction. However, it is important to continue monitoring their condition in case their symptoms worsen and further intervention is required.Rate this question:

Which of the following is the correct technique for chest compressions during two rescuer infant BLS? (page 37)
- A.
Use two thumbs
- B.
Use two hands
- C.
Use two fingers
- D.
Compress two inches
Correct Answer
A. Use two thumbsExplanation
During two rescuer infant BLS, the correct technique for chest compressions is to use two thumbs. This is because infants have smaller chests and using two thumbs allows for better control and accuracy while performing chest compressions. Using two thumbs also helps to distribute the pressure evenly and ensures that the compressions are deep enough to effectively circulate blood and provide oxygen to the infant's vital organs.Rate this question:

Ventilations during two rescuer BLS are best performed using which technique/device? (page 16)
- A.
Pocket mask
- B.
Bag valve mask
- C.
Mouth to mouth
- D.
Mouth to mask
Correct Answer
B. Bag valve maskExplanation
The correct answer is Bag valve mask. During two rescuer BLS, ventilations are best performed using a bag valve mask. This device allows for effective delivery of oxygen to the patient's lungs by providing positive pressure ventilation. It is easier to use and provides better control over the ventilation process compared to other techniques/devices such as pocket mask, mouth to mouth, or mouth to mask.Rate this question:

- A.
30:2
- B.
15:2
- C.
5:1
- D.
3:1
Correct Answer
B. 15:2Explanation
The compression to ventilation ratio for two rescuer child and infant CPR is 15:2. This means that for every 15 compressions, there should be 2 ventilations. This ratio is important in order to provide adequate circulation and oxygenation during CPR. It allows for a balance between chest compressions to maintain blood flow and ventilations to deliver oxygen to the lungs.Rate this question:

Whenever possible, interruptions in chest compressions should be limited to how many seconds? (page 2)
- A.
20
- B.
10
- C.
30
- D.
60
Correct Answer
B. 10Explanation
The correct answer is 10. During chest compressions, interruptions should be limited to 10 seconds whenever possible. This is because interruptions in chest compressions can decrease the effectiveness of cardiopulmonary resuscitation (CPR) and reduce the chances of successful resuscitation. By limiting interruptions to 10 seconds, the flow of blood and oxygen to the brain and other vital organs can be maintained, increasing the likelihood of a positive outcome for the patient.Rate this question:

What is the appropriate depth of compressions for adults and children? (page 4)
- A.
Approximately two inches
- B.
At least one and a half inches
- C.
At least two inches
- D.
About one inch
Correct Answer
C. At least two inchesExplanation
The appropriate depth of compressions for adults and children is at least two inches. This depth is necessary to effectively pump blood through the body and maintain circulation during CPR. Compressions that are too shallow may not provide enough force to generate blood flow, while compressions that are too deep can cause damage to internal organs. Therefore, it is important to ensure that compressions are at least two inches deep to maximize the chances of a successful resuscitation.Rate this question:

If you suspect the victim has a neck or spine injury, you should use which maneuver to open the airway? (page 17)
- A.
Head tilt-chin lift
- B.
Chin to chest
- C.
Jaw thrust
- D.
Neck bend-spine twist
Correct Answer
C. Jaw thrustExplanation
If you suspect the victim has a neck or spine injury, you should use the jaw thrust maneuver to open the airway. This is because the jaw thrust maneuver does not involve tilting or moving the head and neck, which could potentially worsen the injury. Instead, the rescuer uses their fingers to lift the jaw forward, which helps to open the airway without putting any strain on the neck or spine.Rate this question:

If the AED states "No Shock Advised", what is the next most appropriate action? (page 25)
- A.
Begin compressions
- B.
Give two breaths
- C.
Reanalyze the rhythm
- D.
Remove and reposition AED pads
Correct Answer
A. Begin compressionsExplanation
If the AED states "No Shock Advised", it means that the device has analyzed the heart rhythm and determined that a shock is not necessary to restore a normal rhythm. In this situation, the next most appropriate action would be to begin compressions. Compressions are a critical component of cardiopulmonary resuscitation (CPR) and help to circulate oxygenated blood to vital organs. Starting compressions promptly can increase the chances of survival for the patient.Rate this question:

Regardless of the ventilation method/device used, what is the expected outcome when delivering rescue breaths? (page 14)
- A.
Maximum tidal volume
- B.
Hyperinflation of the chest
- C.
Visible chest rise
- D.
Distention of the adbomen
Correct Answer
C. Visible chest riseExplanation
When delivering rescue breaths, the expected outcome is a visible chest rise. This indicates that the air being delivered is entering the lungs and causing them to expand. It is a positive sign that the ventilation is effective and that the patient is receiving adequate oxygenation. The other options, such as maximum tidal volume, hyperinflation of the chest, and distention of the abdomen, are not the expected outcomes of rescue breaths and may indicate improper technique or complications.Rate this question:
