CARDIOPULMONARY RESUSCITATION

1. 1. After you open the airway and pinch the nose of an unconscious adult, which of the following describes the best way to give mouth-to-mouth breaths?

• A. After you open the airway and pinch the nose of an unconscious adult, which of the following describes the best way to give mouth-to-mouth breaths?

• B. Seal your mouth over the victim’s mouth and give 2 breaths, watching for chest rise

• C. Put your mouth on the victim’s mouth and give 5 slow breath over about 2 seconds each watching for chest rise

• D. Put your mouth on the victim’s mouth and give 1 slow breath over about 5 seconds

Answer explanation

Seal your mouth over the victim’s mouth and give 2 breaths, watching for chest rise.

2. Which of the following best describes how you open the victim’s airway to give breaths?

• A. Place one hand on the forehead and the other hand under the chin and tilt the head back slightly

• B. Pull the victim’s head back using their hair

• C. You do not need to tilt the victim’s head back to give breaths

• D. Push the victim’s head back using only a hand on the

       forehead

Answer explanation

To open the victim's airway and give breaths, the best method is to place one hand on the forehead and the other under the chin, then tilt the head back slightly. This position helps to ensure that the airway is clear and open for effective respiration. It is important to be cautious not to touch the person due to the risk of contagious diseases.

3. Which of the following describes the way you should allow the chest to recoil after each chest compression?

•   A. Keep the chest pushed down approximately 1/2  to 1 inch between compressions

• B. Keep your weight on the victim’s chest so the chest it slightly compressed at all times

• C. Compress the chest shallowly with each compression, so you don’t have to release too far

• D. Take your weight off of your hands and allow the chest to

  come back to its normal position.

Answer explanation

After each chest compression, it is important to take your weight off of your hands and allow the chest to come back to its normal position. This allows for complete chest recoil, which is necessary for effective chest compressions. If the chest is not allowed to fully recoil, it may impede blood flow and decrease the effectiveness of the compressions. Therefore, it is crucial to release the pressure and allow the chest to return to its normal position before starting the next compression.

4. What is the primary function of AED?

• A. To monitor heart rate

• B. To start the heart

• C. To deliver an electric shock to the heart

• D. To stop the heart

Answer explanation

An AED's primary function is to deliver an electrical shock to the heart to restore a normal rhythm in case of a cardiac arrest.

5. At what point should an AED be used?

• A. After CPR has been performed

• B. After the patient has stopped breathing

• C. As soon as possible after cardiac arrest

• D. After the arrival of EMS

Answer explanation

An AED should be used as soon as possible after a cardiac arrest has occurred for the highest survival chances.

6. What should you do before using an AED?

• A. Check for responsiveness

• B. Check for a pulse

• C. Start CPR

• D. All of the above

Answer explanation

Before using an AED, it's essential to check for responsiveness, check for a pulse, and start CPR if necessary.

7.When assessing the victim, you should feel for a pulse for:

• A . 3 seconds

• B .5-10 seconds

• C .15-20 seconds

• D .20-30 seconds

Answer explanation

When assessing a victim, feeling for a pulse for 5-10 seconds is recommended. This duration allows for enough time to accurately detect the presence or absence of a pulse. It is important to feel for a pulse as it provides crucial information about the victim's circulation and can help determine the need for immediate medical intervention. Feeling for a pulse for a shorter duration may lead to a false negative result, while feeling for a longer duration may waste valuable time in emergency situations.

8.If you are alone and come upon a person who may need CPR, the FIRST thing you should do is:

• A. Call ambulance

• B .Begin CPR

• C .Go for an AED

• D. Make sure the scene is safe

Answer explanation

In a situation where you are alone and encounter a person who may require CPR, the first thing you should do is ensure the safety of the scene. This is crucial as your own safety should be a priority before providing assistance to others. By assessing the scene for potential hazards or dangers, such as fire, electrical wires, or any other threats, you can minimize the risk to yourself and the person in need. Once you have confirmed that the scene is safe, you can proceed with activating the emergency response system and providing CPR.

9. How many compressions do you give a victim during CPR?

• A. 10

• B.20

• C.5

• D.30

Answer explanation

During CPR, it is recommended to give 30 compressions to a victim. This is because the American Heart Association (AHA) guidelines suggest a compression rate of at least 100-120 compressions per minute. Therefore, in a cycle of CPR, after giving 2 rescue breaths, the rescuer should perform 30 chest compressions at a consistent pace and depth to help circulate oxygenated blood throughout the body and maintain vital organ function.

10.What is the rate of high quality chest compressions?

• A. 100-120/min

• B .80-90/min

• C.120-140/min

• D.70-90/min

Answer explanation

Rate of high quality chest compressions is 100-120 times per min
