Lifeguard Quiz # 2: CPR & AED For The Lifeguard (Ch. 7 & 8)

Defibrillation is the correct answer because it involves delivering an electrical shock to the heart in order to correct abnormal heart rhythms. Asystole refers to a condition where there is no electrical activity in the heart, diastole is the relaxation phase of the heart's cycle, and fibrillation refers to a rapid and irregular heart rhythm. Therefore, defibrillation is the most appropriate term for the process of using electrical shock to restore normal heart rhythm.

It is important for everyone to "stand clear" before using an AED to deliver a shock because there is a risk of getting shocked. The electrical shock delivered by the AED could potentially pass through the victim's body and into anyone who is in contact with the victim or the surrounding area. By standing clear, you minimize the risk of getting shocked and ensure the safety of yourself and others.

To determine if a victim's airway is blocked or open, you initially give them 2 rescue breaths. By providing these breaths, you can assess if the victim's chest rises and falls, indicating that their airway is open and unobstructed. If the chest does not rise, it suggests that the airway may be blocked, and further steps need to be taken to clear the obstruction and provide appropriate care.

Breathing barriers, such as face masks or pocket masks, are designed to protect against disease transmission. These barriers act as a physical barrier between the rescuer and the victim, preventing direct contact with respiratory secretions, such as saliva or droplets, which may contain infectious pathogens. By using a breathing barrier, the rescuer reduces the risk of contracting or spreading diseases, such as respiratory infections or bloodborne pathogens, during rescue breathing or CPR procedures.

The given answer, Adult - 15:2, is incorrect for CPR with one rescuer. The correct ratio for CPR with one rescuer on an adult is 30:2, meaning 30 compressions followed by 2 breaths. This ratio ensures proper circulation and oxygenation during CPR.

When an AED (Automated External Defibrillator) is available and ready to be used, professional rescuers should temporarily stop giving CPR to a victim. This is because an AED is designed to analyze the victim's heart rhythm and deliver an electric shock if necessary to restore a normal heartbeat. CPR, on the other hand, provides manual chest compressions and rescue breaths to circulate oxygenated blood until the AED can be used. By temporarily stopping CPR and using the AED, rescuers can potentially improve the chances of the victim's survival. Therefore, the statement is true.

After the initial analysis, if the AED prompt indicates that "no shock is advised," the next step is to perform 5 cycles (about 2 minutes) of CPR. This is because CPR helps to maintain blood circulation and oxygenation to vital organs, even in the absence of a shockable rhythm. By performing CPR for 5 cycles, rescuers can continue to provide essential life support until further medical assistance arrives. Restarting the AED or beginning rescue breathing would not be the appropriate next steps in this situation.

Compressions should be performed on an adult at a rate of 100 beats per minute (bpm). This rate is recommended by the American Heart Association for effective cardiopulmonary resuscitation (CPR). Compressions at this speed ensure adequate blood flow to the heart and brain, increasing the chances of survival for the individual in cardiac arrest. A rate of 100bpm allows for consistent and rhythmic compressions, which is crucial for maintaining circulation and delivering oxygen to the vital organs.

The correct answer is to give rescue breaths at a rate of 1 rescue breath about every 5 seconds. This is the recommended technique for providing care to an adult who is not moving or breathing but has a pulse. Giving rescue breaths at this rate helps to ensure that the person receives enough oxygen while allowing time for the chest to fully rise and fall between breaths. This technique is crucial in maintaining the person's respiratory function and preventing further complications.

The explanation for the answer "False" is that the consciousness of an infant cannot be checked using the same technique as that of a child. Infants require specialized techniques for assessing their consciousness due to their unique physiology and developmental stage.

Summoning EMS personnel is the most important action step to take when caring for a person who may be experiencing a heart attack. This is because EMS personnel are trained to handle medical emergencies and can provide the necessary medical assistance and transportation to a hospital. They have the equipment and expertise to quickly assess the situation, administer life-saving interventions, and provide appropriate medical care. Time is critical during a heart attack, and summoning EMS personnel ensures that the person receives prompt and professional medical attention, increasing their chances of survival and a positive outcome.

Early rescue is not a specific link in the Cardiac Chain of Survival. The Cardiac Chain of Survival consists of four specific links: early recognition of the emergency and early access to EMS, early CPR, early defibrillation, and early advanced care. Early rescue is not mentioned as one of the specific links in the chain, making it the correct answer.

The CPR/AED for the Lifeguard certification is valid for 1 year. This means that after completing the certification, lifeguards must renew their CPR/AED training every year to ensure they have the most up-to-date knowledge and skills to respond to emergencies effectively. Regular renewal helps lifeguards stay competent in performing CPR and using an AED, which are crucial lifesaving techniques in emergency situations.

The correct depth for compressions while giving CPR to an adult is 1.5 to 2 inches. This depth is recommended by the American Heart Association and is based on scientific evidence and research. It is important to compress the chest with enough depth to adequately circulate blood and oxygen to the vital organs, but not too deep to cause harm. The correct depth ensures effective chest compressions and increases the chances of successful resuscitation.
