According to page 2 of your BLS for Healthcare Provider manual, which of the following is NOT a critical concept of high quality CPR?
Correct Answer
B. Start compressions within 30 seconds of recognition of cardiac arrest
Explanation
The correct answer is "Start compressions within 30 seconds of recognition of cardiac arrest." This is not a critical concept of high quality CPR because it is recommended to start compressions immediately after recognition of cardiac arrest, without waiting for a specific time frame such as 30 seconds. Starting compressions promptly is crucial to improve the chances of survival for the victim.
2.
How many seconds do Healthcare providers check for a pulse on an unresponsive victim? (Page 8).
Correct Answer
A. 5-10
Explanation
Healthcare providers typically check for a pulse on an unresponsive victim for a duration of 5-10 seconds. This time frame allows them to assess whether the victim has a pulse or not. Checking for a pulse is crucial in determining the victim's condition and the appropriate course of action to be taken.
3.
Compressions are performed at a rate of ______ per minute (page 10).
Correct Answer
B. 100
Explanation
The correct answer is 100. This answer is based on the information provided in page 10, which states that compressions are performed at a rate of 100 per minute.
4.
All of the following are steps in using an AED except… (page 20)
Correct Answer
D. Turn off following delivery of shock
Explanation
The correct answer is "Turn off following delivery of shock". This step is not a part of using an AED. After delivering a shock, the AED will automatically analyze the heart rhythm again and determine if another shock is needed.
5.
Once the AED delivers a shock, what is the next most important step for the rescuer? (page 26)
Correct Answer
B. Resume chest compressions
Explanation
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.
6.
What is the compression to ventilation ratio for one rescuer BLS? (page 10)
Correct Answer
B. 30:2
Explanation
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.
7.
According to page 43 of the BLS manual, what is the appropriate ventilation strategy for a victim that has an advanced airway (i.e. endotracheal tube) in place during CPR?
Correct Answer
D. One breath every 6-8 seconds
Explanation
According to the BLS manual, the appropriate ventilation strategy for a victim with an advanced airway (endotracheal tube) in place during CPR is to provide one breath every 6-8 seconds.
8.
Which of the following describes the proper sequence of steps in BLS? (Pages 8-10)
Correct Answer
D. Scene safety, check responsiveness, call for help
Explanation
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.
9.
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)
Correct Answer
A. Every 2 minutes
Explanation
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.
10.
Pulse checks on infants are performed by palpating which artery? (page 35)
Correct Answer
D. Brachial
Explanation
Pulse checks on infants are performed by palpating the brachial artery. The brachial artery is located in the upper arm, between the elbow and the shoulder. It is the artery that supplies blood to the arm and is commonly used to check the pulse in infants because it is easily accessible and can provide an accurate measurement of the heart rate.
11.
Adult sized AED pads can be used on an infant if no pediatric pads or a pediatric capable AED is available. (page 41)
Correct Answer
A. True
Explanation
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.
12.
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)
Correct Answer
C. Monitor their condition
Explanation
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.
13.
Which of the following is the correct technique for chest compressions during two rescuer infant BLS? (page 37)
Correct Answer
A. Use two thumbs
Explanation
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.
14.
Ventilations during two rescuer BLS are best performed using which technique/device? (page 16)
Correct Answer
B. Bag valve mask
Explanation
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.
15.
What is the compression to ventilation ratio for two rescuer child and infant CPR? (page 31 &37)
Correct Answer
B. 15:2
Explanation
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.
16.
Whenever possible, interruptions in chest compressions should be limited to how many seconds? (page 2)
Correct Answer
B. 10
Explanation
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.
17.
What is the appropriate depth of compressions for adults and children? (page 4)
Correct Answer
C. At least two inches
Explanation
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.
18.
If you suspect the victim has a neck or spine injury, you should use which maneuver to open the airway? (page 17)
Correct Answer
C. Jaw thrust
Explanation
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.
19.
If the AED states "No Shock Advised", what is the next most appropriate action? (page 25)
Correct Answer
A. Begin compressions
Explanation
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.
20.
Regardless of the ventilation method/device used, what is the expected outcome when delivering rescue breaths? (page 14)
Correct Answer
C. Visible chest rise
Explanation
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.
