AED Exam: Child Component MCQ Quiz!

1. Causes of cardiac arrest in children include:

Traumatic injuries or accidents

Breathing emergencies

A hard blow to the chest

All of the above

The correct answer is "All of the above." This means that all of the mentioned factors - traumatic injuries or accidents, breathing emergencies, and a hard blow to the chest - can cause cardiac arrest in children. Traumatic injuries or accidents can lead to severe damage to the heart or disrupt its normal functioning. Breathing emergencies, such as choking or drowning, can result in a lack of oxygen supply to the heart, leading to cardiac arrest. Lastly, a hard blow to the chest can cause a sudden interruption in the heart's electrical activity, resulting in cardiac arrest.

2. Which of the following precautions apply when operating an AED?

Do not use an AED on a child lying in water

Do not touch the child while the AED is defibrillating

Do not touch the child while the AED is analyzing

All of the above

When operating an AED, it is important to take certain precautions. One of these precautions is to not use an AED on a child lying in water, as water can conduct electricity and pose a risk of electrocution. Another precaution is to not touch the child while the AED is defibrillating, as this can interfere with the delivery of the electrical shock. Similarly, it is important not to touch the child while the AED is analyzing, as this can also interfere with the device's ability to accurately assess the child's heart rhythm. Therefore, all of the given precautions apply when operating an AED.

3. Which of the following statements about defibrillation is true?

It is more likely to be successful if CPR is witheld

It can be used to restart a heart without any elecftrical activity

It is commonly used on a child complaing of chest pain.

Defibrillation is an electrical shock that is used to help the heart regain a normal rhythm during cardiac arrest. This statement correctly states that defibrillation may help the heart to resume an effective rhythm in a child experiencing cardiac arrest. It is important to note that CPR should not be withheld during defibrillation as it plays a crucial role in maintaining blood flow to the vital organs. Defibrillation is not used to restart a heart without any electrical activity, and it is not commonly used on a child complaining of chest pain.

4. If , after giving 1 shock, the AED prompts "No shock advised," you should:

Immediately reanlyze the rhythm

Resume 5 cycles or about 2 minutes of CPR

Reset the AED by turning it off for 10 seconds

Check the pad palacement on the child's chest

If, after giving 1 shock, the AED prompts "No shock advised," it means that the AED has analyzed the rhythm and determined that a shock is not needed at that moment. In this case, it is important to resume performing CPR for about 2 minutes or 5 cycles. This is because CPR helps to circulate oxygenated blood to the vital organs and can improve the chances of the child's survival. The prompt to resume CPR indicates that the AED has detected a non-shockable rhythm and further CPR is necessary.

5. Why is it important to stand clear and touch the child before analyzing the heart rhythm or delivering a shock?

The AED will turn off.

Your or someone else could become injured by the shock.

You may prevent the AED from analyzing the heart rhythm properly.

Both b and c

It is important to stand clear and touch the child before analyzing the heart rhythm or delivering a shock because both options b and c are correct. If you or someone else is in contact with the child when the shock is delivered, they could become injured by the shock. Additionally, if you are touching the child while the AED is analyzing the heart rhythm, it may prevent the AED from properly analyzing the rhythm and delivering the appropriate treatment. Therefore, it is crucial to stand clear and ensure there is no contact with the child before proceeding with these actions.

6. Before delivering a shock with an AED to a child, you should:

Look for a foreign object in the child's mouth.

Place the child on his or her side.

Have another responder hold the child.

Ensure that on one, including you, is touching or is in contact with the child.

Before delivering a shock with an AED to a child, it is crucial to ensure that no one, including yourself, is touching or in contact with the child. This is important because touching the child during the shock can interfere with the delivery of the electrical current and potentially harm the person delivering the shock as well. It is important to create a clear and safe space around the child to ensure the effectiveness of the AED shock and to minimize any potential risks.

7. What should you do if the pediatric AED pads risk touching each other when placed on a smaller child's chest?

Place one pad on the child's chest and the other on the child's back

Leave them as they are--it does not matter if they touch.

Use adult AED padsthem as they are--itdoes nto matter ifthey touch

Use just one pad

If the pediatric AED pads risk touching each other when placed on a smaller child's chest, the best course of action is to place one pad on the child's chest and the other on the child's back. This is because the pads need to be positioned correctly to ensure effective delivery of the electrical shock to the heart. Placing one pad on the chest and the other on the back allows for proper placement and reduces the risk of the pads touching each other.

8. You have just responded with an AED to an emergency involving a 7-year-old child. You check the child and find no signs of life. What should you do first to prepare the AED for use?

Turn on the AED

Deliver a shock

Stand clear

Give 5 minute sof CPR

To prepare the AED for use in an emergency involving a 7-year-old child, the first step is to turn on the AED. This allows the device to power up and be ready for operation. Once the AED is turned on, the rescuer can follow the prompts and instructions provided by the device to deliver the necessary shock or perform CPR if needed. Therefore, turning on the AED is the initial step to ensure that it is ready to be used effectively in resuscitation efforts.

9. A responder who is alone and witnesses a child who suddenly collapses in cardiac arrest should:

Give 5 minutes of CPR before taking other actions, such as calling 9-1-1 or the local emergency number.

Give rescue breathing only

Call for help first

Give 7 minutes of CPR and then call for help

In a situation where a responder is alone and witnesses a child suddenly collapsing in cardiac arrest, the correct action is to call for help first. This is because time is of the essence in a cardiac arrest situation, and it is crucial to alert emergency services as soon as possible. Once help is on the way, the responder can then begin administering CPR. Starting with CPR before calling for help may waste valuable time that could be used to get professional medical assistance to the scene.

10. The pediatric AED pads for a child can be placed on:

The upper left and the lower right side of the child's chest

The upper right and the lower left side of the child's chest

The child's upper right arm and the left side of his or her chest.

None of the above

The correct answer is placing the pediatric AED pads on the upper right and lower left side of the child's chest. This placement ensures that the pads are positioned correctly to deliver the electrical shock to the child's heart in case of a cardiac arrest. Placing the pads on the upper left and lower right side or on the child's upper right arm and left side of the chest would not provide the optimal position for delivering the shock.
