What is the recommended compression rate for adult CPR?
60 - 80 compressions per minute
120 - 140 compressions per minute
80 - 100 compressions per minute
100 - 120 compressions per minute
Guidelines recommend a compression rate of 100 - 120 per minute for effective blood flow during adult CPR. Rates slower than this may not generate sufficient perfusion, and rates faster may not allow full chest recoil.
What is the correct compression depth for adult CPR?
5 - 6 cm
3 - 4 cm
2 - 3 cm
7 - 8 cm
Adult chest compressions should be at least 5 cm (2 - 2.4 inches) deep to generate adequate blood flow. Compressing significantly deeper increases risk of injury without added benefit.
Where should you place your hands to deliver chest compressions on an adult?
Center of the chest on the lower half of the sternum
On the left side of the chest
Just below the xiphoid process
Center of the chest on the upper half of the sternum
Hands should be positioned on the center of the chest over the lower half of the sternum to maximize perfusion and avoid injury to the xiphoid process. Incorrect placement reduces efficacy and raises risk of complications.
What compression-to-ventilation ratio is recommended for a single rescuer performing CPR on an adult?
30:2
20:2
15:1
15:2
The recommended ratio for a single rescuer on an adult is 30 compressions followed by 2 ventilations. This balance maintains circulation and oxygenation effectively.
When should you activate emergency medical services during a suspected cardiac arrest?
After two minutes of CPR
After administering an AED shock
Only if breathing returns
Immediately upon recognizing unresponsiveness and absent normal breathing
Calling emergency services immediately ensures rapid advanced care and defibrillation access. Delaying notification can reduce survival chances.
During CPR on a child (age 1 to puberty), what is the recommended compression depth?
At least one-third the chest depth (about 5 cm)
About 3 cm
2 - 3 inches
At least 8 cm
Child compressions should reach about one-third of the chest's anterior - posterior dimension, roughly 5 cm (2 inches). Too shallow compressions are ineffective.
A lone rescuer finds an unresponsive 3-year-old child who is not breathing normally. According to CPR guidelines, what should the rescuer do first?
Call EMS immediately then start CPR
Ask a bystander to retrieve a first aid kit
Wait for visible chest rise before checking pulse
Perform CPR for about two minutes (five cycles) before calling EMS
For a lone rescuer with a child, perform about two minutes (five cycles) of CPR before leaving to call EMS, as early ventilations and compressions are crucial for pediatric victims.
Where should AED pads be placed on an adult victim?
One pad above the right collarbone and the other on the left lateral chest
Both pads on the victim's back
Both pads on the left side of the chest
One pad on the back and one on the chest
Standard AED pad placement is one under the right collarbone and the other on the left side below the armpit, ensuring the shock traverses the heart.
What must you ensure before delivering an AED shock?
That the victim has a pulse
That the victim is lying face down
That you have performed ten chest compressions
That no one is touching the victim
Verifying no one is in contact with the victim prevents accidental shock delivery to bystanders and ensures the full energy is delivered.
Why is it important for rescuers to wear personal protective equipment (PPE) during CPR?
To reduce rescuer fatigue
To improve compression depth quality
To increase patient trust
To protect against bloodborne pathogen exposure
PPE such as gloves and masks safeguards rescuers from bloodborne pathogens and bodily fluids, maintaining safety and infection control.
What is the recommended method to open the airway of an adult suspected of having a spinal injury?
Head tilt - chin lift
Manual displacement of the hyoid bone
Jaw thrust without head extension
Shoulder tilt technique
The jaw thrust maneuver opens the airway while minimizing neck movement, which is critical when spinal injury is suspected.
How often should rescuers switch roles during continuous CPR to prevent fatigue?
After every ten breaths
Every minute
Every 30 seconds
Approximately every two minutes
Swapping compressors about every two minutes helps maintain high-quality compressions by reducing fatigue.
During two-rescuer CPR on an infant, what compression-to-ventilation ratio should be used?
3:1
15:2
30:2
10:1
Two-rescuer infant CPR uses a 15:2 ratio to provide more frequent ventilations appropriate for infants' physiology.
Which sign indicates that chest compressions are effective during CPR?
Sudden onset of gasping
Return of organized electrical rhythm
Visible chest rise with each compression
Presence of a palpable pulse between compressions
Feeling a carotid or femoral pulse between compressions indicates that blood is being circulated effectively with each compression cycle.
In adult rescue breathing, how long should each breath delivery take to achieve visible chest rise?
About 2 seconds
About 1 second
About 3 seconds
About 0.5 seconds
Deliver each breath over about one second to allow adequate lung inflation without causing gastric insufflation.
Which action should you take when using an AED on a child under 8 years old if pediatric pads are unavailable?
Use the defibrillator in manual mode only
Do not use the AED
Use adult pads with anterior-posterior placement
Place both pads on the back
If pediatric pads are not available, adult pads can be used in an anterior-posterior position to avoid pad overlap and deliver an effective shock.
In a two-rescuer CPR scenario for an adult who has an advanced airway in place, what is the recommended compression and ventilation protocol?
Continuous compressions with no breaths
30:2 ratio with compression pauses
15:2 ratio with minimal pauses
Continuous compressions at 100 - 120/min with one breath every 6 seconds
With an advanced airway, rescuers provide continuous compressions at 100 - 120/min and deliver one breath every 6 seconds without pausing compressions.
How should rescuers modify their CPR approach if the victim shows signs of life (movement or normal breathing) after an AED shock?
Resume compressions immediately
Continue with two minutes of compressions then reassess
Position in recovery and monitor until EMS arrives
Deliver another shock immediately
If spontaneous signs of life return, place the victim in the recovery position and continuously monitor until EMS personnel arrive.
What is the maximum acceptable interruption duration during chest compressions to deliver a shock or ventilation?
Less than 20 seconds
Less than 30 seconds
Less than 10 seconds
Less than 5 seconds
Interruptions to chest compressions should be kept under 10 seconds to preserve coronary and cerebral perfusion.
Why is it important to check the AED pads and battery status regularly as part of rescuer safety measures?
To confirm readiness and avoid malfunction during an emergency
To practice pad removal techniques
To verify the device is properly calibrated
To ensure the device meets color standards
Routine checks of pad condition and battery life ensure the AED will function correctly when needed, preventing delays or device failure.

Cheat Sheet

  1. Master the C-A-B sequence - Think of CPR as your superhero routine: first chest compressions to jumpstart blood flow, then open the airway, and finish with rescue breaths. Following this C-A-B combo keeps your rescue mission on track!
  2. Hit the right compression depth - For adults, press down at least 2 inches (5 cm) but no more than 2.4 inches (6 cm) to ensure strong blood circulation. Too shallow or too deep and you might miss the beat!
  3. Keep the perfect pace - Aim for 100 to 120 compressions per minute - that's about the tempo of a lively pop song. Staying in rhythm optimizes the chance of reviving the heartbeat.
  4. Use the right infant technique - With two rescuers, wrap your hands around the baby's chest with thumbs on the sternum, or use two fingers if you're solo. This tailored touch ensures safe, effective compressions for tiny patients.
  5. Allow full chest recoil - Let the chest spring back completely after each compression so the heart refills with blood. Avoid leaning on the chest between pushes and keep the flow going!
  6. Open the airway properly - Tilt the head back and lift the chin to clear the path for breaths. This simple maneuver can make rescue breaths far more effective.
  7. Follow AED voice prompts - When using an Automated External Defibrillator, listen closely to its instructions and never touch the person during a shock. It's like having a coach whispering the playbook for you.
  8. Adjust depth for kids - For children, aim for compressions one-third the depth of the chest - around 2 inches (5 cm) - to match their smaller frame. Accurate depth boosts blood flow without causing harm.
  9. Call for help first - If someone is unresponsive or breathing abnormally, dial emergency services before you begin CPR. Fast activation of professional responders is key to winning the survival race.
  10. Practice to stay sharp - Regular practice and staying up-to-date with guidelines turns CPR skills into second nature. Confidence and readiness can mean the difference between panic and power in an emergency.
