What does CPR stand for?
Cardiac Pulmonary Response
Cardiopulmonary Resuscitation
Circulatory Pressure Response
Central Pulmonary Recovery
CPR stands for Cardiopulmonary Resuscitation. This lifesaving technique is used to manually preserve brain function until further measures restore spontaneous blood circulation and breathing.
What is the first step in performing CPR on an unresponsive person?
Begin chest compressions immediately
Check responsiveness and call for help
Look for a pulse
Open the airway first
The first step is to check if the person is responsive and, if not, call for emergency assistance. This ensures help is on the way while you prepare to perform CPR.
When you perform chest compressions on an adult, what is the recommended depth?
At least 2 inches
No more than 1 inch
Less than 1 inch
3 to 4 inches
For effective CPR, adult chest compressions should be at least 2 inches deep. This depth helps create sufficient pressure to circulate blood during cardiac arrest.
What is the recommended compression rate for adult CPR?
100-120 compressions per minute
120-140 compressions per minute
60-80 compressions per minute
80-100 compressions per minute
A compression rate of 100-120 per minute is recommended for adult CPR. This rate helps maintain adequate blood flow during cardiac emergencies.
How should you call for help before starting CPR if you are alone?
Wait to see if someone else calls for help
Begin CPR immediately without calling
Call a friend
Call 911 or the local emergency number first before starting CPR
When you are alone, you should call 911 or your local emergency number immediately before initiating CPR. This step ensures that help is summoned while you provide essential care.
What is the purpose of chest compressions during CPR?
To stimulate the heartbeat naturally
To provide oxygen to the lungs
To manually pump blood through the heart
To assess the patient's responsiveness
Chest compressions help pump blood when the heart is not effectively circulating blood on its own. They are essential for maintaining circulation to the brain and other vital organs during a cardiac arrest.
In which situation is it appropriate to use an Automated External Defibrillator (AED)?
After 10 minutes of CPR
When a victim is conscious but in distress
When a victim is unresponsive with no normal breathing and a shockable rhythm is suspected
Only in hospital settings
An AED is used when the victim is unresponsive, not breathing normally, and a shockable heart rhythm is suspected. The device analyzes the heart rhythm and advises if a shock is necessary to restore a normal rhythm.
Which of the following is a key step in ensuring the safety of both the rescuer and the victim during CPR?
Do not worry about the environment
Perform CPR immediately without checking the scene
Ask bystanders to help regardless of safety
Check the scene for dangers before approaching the victim
Assessing the scene for potential dangers is vital to the safety of both the rescuer and the victim. Ensuring a safe environment minimizes additional risks before initiating CPR.
What is the recommended ratio of chest compressions to rescue breaths for an adult during CPR?
30 compressions to 2 breaths
20 compressions to 2 breaths
5 compressions to 1 breath
15 compressions to 2 breaths
The standard adult CPR ratio of compressions to breaths is 30:2. This ratio ensures effective circulation while providing oxygen to the victim.
How can you assess if a victim is in cardiac arrest before performing CPR?
Ask the victim to talk
Look at skin color only
Check for responsiveness, absence of normal breathing, and no pulse
Only check if the victim is choking
Determining cardiac arrest involves checking if the victim is unresponsive, not breathing normally, and has no detectable pulse. These assessments help decide if CPR is required immediately.
What modification is recommended for performing CPR on children compared to adults?
Use the same technique as adults
Use a higher compression rate
Do not perform rescue breathing
Use less force during compressions
When performing CPR on children, less force is used to accommodate their smaller and more delicate chest anatomy. Adjusting the technique helps avoid injury while still providing effective compressions.
What is the significance of the 'chain of survival' in CPR?
It refers to a rope used in rescue operations
It outlines the critical steps for effective resuscitation
It is a certification requirement
It describes a time limit for performing CPR
The chain of survival is a sequence of critical actions including early recognition, immediate CPR, rapid defibrillation, and advanced care. Understanding each link helps maximize a victim's chance of survival during a cardiac emergency.
When using an AED, what should you do immediately after the device advises a shock?
Ensure no one is touching the victim and deliver the shock
Continue to analyze the rhythm before shocking
Begin chest compressions immediately
Check the victim's pulse
After the AED advises a shock, you must clear the area to ensure no one is in contact with the victim. Delivering the shock promptly after ensuring safety optimizes the chance of restoring a normal heart rhythm.
Why is it important to allow complete chest recoil between compressions?
It increases the rate of compressions
It allows the heart to refill with blood
It prevents the victim from regaining consciousness
It minimizes fatigue
Allowing full chest recoil ensures that the heart refills with blood between compressions. This pause is critical for maintaining effective circulation during CPR.
Which factor is essential when assessing the need for rescue breaths during CPR?
The scene lighting conditions
The victim's skin color
The victim's age
The victim's breathing condition
Assessing the victim's breathing condition is crucial to determine if rescue breaths are needed. Adequate oxygenation plays a key role in the treatment of cardiac arrest and must be evaluated properly.
During CPR on an infant, what is the recommended compression technique?
Both hands on the chest like an adult
Two-finger chest compressions at the center of the chest
Back blows without compressions
Heel of one hand with full force
For infants, the recommended technique is to use two fingers for chest compressions at the center of the chest. This method ensures that the applied force is appropriate for their small and delicate structure.
In a scenario where an adult victim is suspected of having a foreign body airway obstruction, what is the first aid response?
Perform the Heimlich maneuver (abdominal thrusts)
Immediately use an AED
Encourage the victim to cough
Begin standard CPR
The first aid response for an adult with a suspected airway obstruction is to perform the Heimlich maneuver. This technique is designed to expel the foreign object from the airway before the situation escalates to cardiac arrest.
How does the presence of an advanced airway (like an endotracheal tube) change the CPR process?
It requires a higher compression rate
It eliminates the need for rescue breathing
It shifts the ventilation rate to continuous chest compressions with asynchronous breaths
No change is made in CPR technique
With an advanced airway in place, rescuers can perform continuous chest compressions while providing asynchronous ventilations. This adjustment minimizes interruptions and optimizes oxygen delivery during CPR.
What is a crucial consideration when performing CPR on a pregnant woman?
Tilt the patient to the left to avoid aortocaval compression
No modifications are needed for pregnant patients
Increase the compression depth by 1 inch
Perform compressions on the abdomen
When performing CPR on a pregnant woman, it is important to tilt her to the left to relieve pressure on the aorta and inferior vena cava. This modification helps maintain better blood flow and increases the effectiveness of resuscitation.
Why should a rescuer minimize interruptions in chest compressions during CPR?
To allow for frequent blood pressure checks
To maintain coronary perfusion pressure
To reduce the risk of rib fractures
To conserve the rescuer's energy
Minimizing interruptions in chest compressions helps maintain coronary perfusion pressure, which is critical for the heart's oxygen supply. Continuous compressions are associated with higher survival rates during cardiac arrest.

HOSA CPR First Aid Practice Test Cheat Sheet

  1. Understand the importance of early CPR - When the heart stops, seconds count! Immediate CPR can double or triple a person's chance of survival by keeping oxygenated blood flowing to vital organs. Think of yourself as the first link in the chain of survival when you step in to help. AHA CPR in Schools
  2. Learn the correct compression-to-ventilation ratio - In adult CPR, the magic numbers are 30 chest compressions followed by 2 rescue breaths. This 30:2 rhythm maximizes blood flow while giving the lungs a chance to refill with oxygen. Practicing on a manikin helps you nail the timing like a pro. Adult CPR Ratio
  3. Master the use of an Automated External Defibrillator (AED) - AEDs aren't as scary as they look; they actually talk you through each step! Quick use of an AED can restore a normal heart rhythm and dramatically improve survival rates. Familiarize yourself with pad placement and voice prompts to stay calm under pressure. AED Operation Guide
  4. Recognize the signs of choking and the appropriate response - If someone can't talk, breathe, or cough, they're likely choking and need immediate help. Perform abdominal thrusts (Heimlich maneuver) to dislodge the blockage and restore airflow. Don't be shy - acting fast can turn a panicked moment into a rescued life. Choking Response Steps
  5. Identify the different types of open wounds - Abrasions, incisions, lacerations, punctures, avulsions, and amputations each have their own first-aid checklist. Knowing the differences helps you choose the right cleaning and dressing techniques. A quick diagnosis can prevent infection and speed healing. Wound Classification
  6. Understand the causes and signs of shock - Shock is your body's emergency response to severe injury, blood loss, or dehydration. Look for rapid breathing, cool clammy skin, and altered mental state. Early recognition and laying the person flat with elevated legs can stabilize them until help arrives. Shock Symptoms
  7. Learn the proper care for minor and major open wounds - A gentle clean with soap and water works for scrapes, while major lacerations demand direct pressure and professional attention. Always check for debris, apply antiseptic, and cover with a sterile dressing. Keeping wounds clean and monitored helps avoid those dreaded infections. Wound Care Steps
  8. Recognize the signs of internal bleeding - Internal bleeding doesn't always show visible blood, but it often causes bruising, swelling, and unexplained pain. Rapid breathing, dizziness, and a dropping blood pressure are major red flags. Immediate medical care is essential to prevent life-threatening complications. Internal Bleeding Clues
  9. Understand the importance of early defibrillation - Using an AED within the first few minutes of cardiac arrest can be the difference between life and death. Each minute without defibrillation drops survival rates by about 10%, so speed is everything. Don't wait - grab the nearest AED and follow its voice instructions. Defibrillation Timing
  10. Be aware of the psychological aspects of emergency response - Ever heard of the "bystander effect"? It's when people freeze in emergencies because they assume someone else will step in. Understanding this can motivate you to break the silence, take charge, and save a life. Confidence and clear instructions often rally others to help too. Bystander Effect
