You have noticed a potential victim and ensured the scene is safe. What is your next step?
Correct Answer
B. Check for victim's responsiveness
Explanation
After ensuring scene safety, the next step is to check for victim’s responsiveness. Assess if the person is conscious and breathing. If unresponsive, call for help and begin appropriate first aid measures. Remember to maintain an open airway and provide rescue breathing if needed. You can also check for signs of life, such as pulse and bleeding, and apply pressure or bandages if necessary.
2.
You notice a 48-year-old male lying on the grass in the middle of a park. You have ensured that the scene is safe and checked for responsiveness. After checking for a carotid pulse you find that the victim has no pulse and is unresponsive. You immediately tell a bystander to call 9-1-1 and get an AED. What should you do next?
Correct Answer
D. Get down to bare chest and begin CPR starting with chest compressions
Explanation
In this situation, immediately begin CPR with chest compressions at a rate of 100-120 per minute. While waiting for the AED, skip rescue breaths for adults in cardiac arrest as chest compressions are the priority. Avoid abdominal thrusts, as they are not recommended for bystander CPR. Focus on high-quality chest compressions until help arrives.
3.
What is the correct rate of compressions?
Correct Answer
C. 100
Explanation
In adult cardiopulmonary resuscitation (CPR), the correct rate of chest compressions is 100 - 120 per minute. Here's why the other options are incorrect: 40: This is too slow to maintain adequate blood flow during cardiac arrest. 80: While better than 40, it's still below the recommended range for optimal blood flow. 60: This is also too slow and wouldn't provide enough chest compressions to maximize the chances of survival. Therefore, 100 - 120 compressions per minute is the correct and recommended rate for adult CPR.
4.
You are giving compressions on an adult at a rate of at least 100 compressions per minute. What is the correct depth for these compressions?
Correct Answer
B. At least 2 inches
Explanation
The correct depth for chest compressions on an adult during CPR is at least 2 inches (5 cm), but no more than 2.4 inches (6 cm). Aim for deep and forceful compressions to maximize blood flow during cardiac arrest. While exceeding 2 inches won't harm, focusing on ensuring at least 2 inches ensures effectiveness while minimizing the risk of injury.
5.
During CPR on an adult victim, the compression-to-breath ratio is:
Correct Answer
A. Give 2 breaths after every 30 compressions
Explanation
During CPR on an adult victim, the compression-to-breath ratio is to give 2 breaths after every 30 compressions. This is the recommended ratio by the American Heart Association (AHA) for adult CPR. The purpose of this ratio is to ensure that adequate oxygen is being delivered to the victim's lungs while also maintaining circulation through chest compressions. By giving 2 breaths after 30 compressions, it allows for a balance between providing oxygen and maintaining blood flow to vital organs. This ratio helps to maximize the chances of survival for the victim.
6.
What is the correct hand placement for compressions on an infant victim?
Correct Answer
C. Use two fingers when performing compressions on an infant
Explanation
The correct hand placement for chest compressions on an infant victim is to use two fingers, specifically the middle and ring fingers, placed in the center of the breastbone just below the nipple line.Here's why other options are incorrect:Use 2 hands: Using both hands on an infant's chest can be too forceful and risk injury.Use one hand: One hand might not provide enough force for effective compressions.Do not give compressions: CPR, including chest compressions, is crucial for infants in cardiac arrest.Remember, infant CPR requires specific techniques and adjustments for their smaller size and delicate bodies. It's always best to seek professional training to ensure proper CPR practices.
7.
You have started CPR on an infant victim. What is the recommended compression depth?
Correct Answer
C. At least an inch and a half
Explanation
The recommended compression depth for CPR on an infant victim is at least an inch and a half. This depth ensures that effective compressions are being performed, allowing for proper blood flow and oxygenation. It is important to follow these guidelines to increase the chances of a successful resuscitation.
8.
Check for a carotid pulse in an infant when beginning the steps of CPR.
Correct Answer
B. False
Explanation
False. When beginning the steps of CPR for an infant, you should first check for responsiveness and then check for breathing. If the infant is not breathing normally, CPR should be initiated. In CPR for infants, chest compressions are the first step, not checking for a carotid pulse. This is because compressions are more critical for infants in cardiac arrest, and attempting to locate a carotid pulse can delay the start of chest compressions.
9.
When giving adequate breaths to an infant, you know they are effective when you see chest rise and fall.
Correct Answer
A. True
Explanation
When giving adequate breaths to an infant, it is important to ensure that the chest rises and falls. This indicates that the air is entering the lungs and the baby is receiving proper ventilation. Seeing the stomach rise may indicate that the breaths are not being given correctly and the air is not reaching the lungs. Therefore, the correct answer is true.
10.
You are alone and find a potential victim. What is your first step?
Correct Answer
B. Ensure scene safety
Explanation
Your first step when encountering a potential victim is to ensure scene safety. Before providing any assistance, it’s crucial to assess the surroundings for hazards that could endanger you or the victim. Once you’ve confirmed safety, proceed with the appropriate actions based on the situation. Remember, safety comes first!
11.
You are giving CPR to a 5-year-old child. A second rescuer comes by and states they know CPR. What happens to your Compression to Breath ratio when you add the second rescuer?
Correct Answer
C. It changes - 15 compressions to 2 breaths.
Explanation
When a second rescuer joins in 2-rescuer child CPR, the compression-to-breath ratio changes to 15 compressions and 2 breaths per cycle for each rescuer, allowing for continuous chest compressions and appropriate ventilation. Rescuers should alternate roles after each cycle to maintain efficiency and effectiveness.
12.
When should you use the two thumb-encircling hands technique on an infant?
Correct Answer
D. When there are 2 rescuers present for CPR
Explanation
The two thumb-encircling hands technique is recommended during infant CPR when there are two rescuers available. This method allows for more effective and consistent chest compressions, as the thumbs can deliver compressions while the fingers provide support around the infant's chest. It also helps maintain a more even pressure distribution during compressions, which is crucial for the infant's small and delicate chest. The other options do not correctly describe when this technique should be used.
13.
You are performing CPR on an adult victim. The second rescuer has arrived with the AED and turned it on. What is their next step?
Correct Answer
B. Place the pads on the victim's bare chest
Explanation
The next step for the second rescuer, after turning on the AED, is to place the pads on the victim's bare chest. This ensures proper contact with the skin, allowing the AED to accurately analyze the victim's heart rhythm and deliver appropriate shocks if necessary. Placing the pads over the victim's clothes may impede the device's effectiveness. Therefore, it is essential to follow proper protocol and apply the pads directly to the bare chest for optimal functionality.
14.
After the AED has delivered the shock you should ___________________.
Correct Answer
A. Continue CPR beginning with compressions
Explanation
After the AED has delivered the shock, you should continue CPR beginning with compressions. This is because CPR (cardiopulmonary resuscitation) is a crucial life-saving technique that helps maintain blood flow to vital organs. Compressions help to circulate oxygenated blood to the brain and other organs, increasing the chances of survival. Giving 2 breaths or waiting for the AED to reanalyze are not immediate priorities after delivering the shock. Turning off the AED is not recommended as it may be needed for further shocks or instructions.
15.

16.
Use abdominal thrusts to relieve choking in a conscious infant. State true or false.
Correct Answer
B. False - Use back slaps and chest thrusts for a choking infant
Explanation
The given answer is false. When a conscious infant is choking, abdominal thrusts should be used to relieve the obstruction. Back slaps and chest thrusts are used for a conscious choking adult or child, not for an infant.
17.
Rescue Breathing is used for a victim who is unconscious but has a pulse. What is the correct rate for rescue breathing in an adult?
Correct Answer
B. 1 breath every 5 to 6 seconds
Explanation
The correct rate for rescue breathing in an adult is 1 breath every 5 to 6 seconds. This rate allows for enough time for the breath to be delivered effectively while also allowing for adequate time for the victim to exhale. It ensures that the victim is receiving enough oxygen to support their vital functions without causing excessive inflation of the lungs.
18.
Rescue Breathing is used for a victim who is unconscious but has a pulse. What is the correct rate for rescue breathing in a child or infant?
Correct Answer
A. 1 breath every 3 to 5 seconds
Explanation
The correct rate for rescue breathing in a child or infant is 1 breath every 3 to 5 seconds. This rate ensures that the victim is receiving enough oxygen to maintain their vital functions while also allowing time for the breaths to be effective. It is important to provide rescue breathing at the appropriate rate to prevent further harm and support the victim's recovery.
19.
If you find an unconscious child without a pulse, who is not breathing, you should complete 5 cycles or 2 minutes of CPR before calling 9-1-1.
Correct Answer
A. True
Explanation
When you find an unconscious child without a pulse who is not breathing, the recommended procedure is to start CPR immediately. For a lone rescuer, it's advised to perform 5 cycles or approximately 2 minutes of CPR before calling 9-1-1. This guideline ensures that the child receives critical chest compressions and breaths as soon as possible, increasing the chances of survival. After performing CPR for this initial period, the rescuer should then call emergency services.

We should use a head tilt-chin lift to open the airway in an adult victim when you do not suspect a cervical spine injury.
Correct Answer
A. True
Explanation
True. A head tilt-chin lift maneuver is appropriate for opening the airway in an adult victim when a cervical spine injury is not suspected. This technique involves gently tilting the victim's head back with one hand on the forehead while lifting the chin with two fingers of the other hand. This action helps to align the airway for effective breathing without risking further injury to the cervical spine.
