What should you do first when you arrive at an emergency scene?

• Start CPR immediately

• Call 9-1-1

• Survey the scene for safety

• Check for responsiveness

Answer explanation

The first step at an emergency scene is to survey for safety. Ensuring the area is safe protects both the responder and the victim from further harm before providing assistance or calling for help.

If the scene is unsafe, what should you do?

• Approach the victim carefully

• Wait for someone else to arrive

• Ignore the situation

• Call 9-1-1 from a safe distance

Answer explanation

In an unsafe scene, the priority is to ensure your safety first. Calling 9-1-1 from a safe distance allows professionals to handle the situation without putting yourself at risk, making it the correct choice.

How should you check for responsiveness?

• Call their name

• Shake the person

• Tap and shout

• Shout loudly

Answer explanation

To check for responsiveness, 'tap and shout' is the best method as it combines physical stimulation with auditory cues, ensuring a higher chance of eliciting a response compared to just calling their name or shaking them.

What should you do if the person is non-responsive and you are in a hospital?

• Wait for a doctor

• Press the code button

• Call 9-1-1

• Start CPR immediately

Answer explanation

In a hospital, if a person is non-responsive, you should press the code button. This alerts medical staff immediately, ensuring that trained professionals can provide the necessary assistance quickly.

What is an agonal breath?

• A normal breath

• A deep sigh

• A shallow breath

• A gasp indicating cardiac arrest

Answer explanation

An agonal breath is a gasp that occurs during cardiac arrest, indicating a lack of normal breathing. It is not a normal, deep, or shallow breath, but rather a sign of a critical medical emergency.

What is the first step in CPR if the victim is pulseless?

• Start chest compressions

• Check airway

• Call for help

• Give rescue breaths

Answer explanation

The first step in CPR for a pulseless victim is to start chest compressions. This action helps maintain blood flow to vital organs until further help arrives.

What is the correct hand placement for chest compressions?

• On the left side of the chest

• On the xiphoid process

• In the center of the chest

• On the throat

Answer explanation

The correct hand placement for chest compressions is in the center of the chest, specifically on the lower half of the sternum. This position allows for effective compressions to circulate blood during CPR.

How deep should chest compressions be for an average-sized adult?

• 4 inches

• 2 inches

• 1 inch

• 3 inches

Answer explanation

Chest compressions for an average-sized adult should be at least 2 inches deep to ensure effective blood circulation during CPR. This depth helps to compress the heart adequately.

How many chest compressions should be given before giving rescue breaths?

• 40 compressions

• 30 compressions

• 20 compressions

• 10 compressions

Answer explanation

In CPR, the recommended ratio is 30 chest compressions followed by 2 rescue breaths. Therefore, the correct answer is 30 compressions before giving rescue breaths.

What is the purpose of allowing chest recoil during compressions?

• To let the heart fill with blood

• To rest the rescuer

• To give rescue breaths

• To check for a pulse

Answer explanation

Allowing chest recoil during compressions is crucial as it enables the heart to fill with blood. This ensures effective circulation and increases the chances of survival during cardiac arrest.
