What is the recommended compression rate per minute for adult CPR?
120 to 140 compressions per minute
100 to 120 compressions per minute
80 to 100 compressions per minute
60 to 80 compressions per minute
A rate of 100 to 120 compressions per minute is recommended to maintain effective blood flow and optimize coronary perfusion pressure. Rates below or above this range may reduce the efficacy of CPR.
How deep should chest compressions be when performing CPR on an adult?
5 to 6 centimeters
3 to 4 centimeters
2 to 3 centimeters
7 to 8 centimeters
Adult chest compressions should be about 5 to 6 cm deep to ensure adequate blood flow to vital organs. Shallow or excessively deep compressions can either be ineffective or cause injury.
What compression-to-ventilation ratio is recommended for one-rescuer CPR on an adult?
30 compressions to 1 breath
15 compressions to 2 breaths
15 compressions to 1 breath
30 compressions to 2 breaths
For adults, a one-rescuer CPR protocol uses 30 chest compressions followed by 2 rescue breaths. This ratio helps balance effective circulatory support with adequate oxygenation.
When you find an unresponsive adult, what is the first action you should take?
Tap and shout to assess responsiveness
Call emergency services immediately
Start chest compressions
Check for breathing
Assessing responsiveness by tapping the person and shouting helps determine if CPR is needed before calling emergency services. This initial check ensures you only start CPR on truly unresponsive individuals.
Where should your hands be placed for chest compressions on an adult?
On the upper part of the sternum just below the clavicles
Directly over the xiphoid process
On the lower half of the sternum at the center of the chest
On the left side of the ribs
Proper hand placement is on the lower half of the sternum at the center of the chest to apply force directly over the heart. This maximizes the efficiency of compressions and reduces the risk of injury.
Which AED component is responsible for analyzing a patient's heart rhythm?
Battery pack
Rhythm analysis algorithm
Display screen
Shock button
The AED's rhythm analysis algorithm interprets the ECG signal to determine if a shockable rhythm is present. The other components power the device, display instructions, or deliver shock energy.
How should AED electrode pads be positioned on an adult's chest?
Both pads on the lower sternum side by side
Both pads on the left side of the chest
One pad below the right collarbone and one on the left side of the chest
One pad on the upper abdomen and one on the back
Proper pad placement - one under the right collarbone and the other on the left lateral chest - ensures the electric current passes through the heart. Incorrect placement can reduce the effectiveness of defibrillation.
Which cardiac rhythm identified by an AED is shockable?
Asystole
Sinus bradycardia
Atrial fibrillation
Ventricular fibrillation
Ventricular fibrillation is a shockable rhythm because it involves chaotic electrical activity that requires defibrillation to restore an organized heartbeat. Asystole and other rhythms are treated with CPR and medications rather than shocks.
If chest rises do not occur during rescue breaths, what should you do next?
Reposition the head and seal the airway
Give faster, harder breaths
Switch to abdominal thrusts
Stop compressions permanently
Repositioning the head using the head tilt - chin lift ensures the airway is open and allows breaths to enter the lungs. Without an open airway, breaths will not inflate the chest.
Immediately after delivering a shock with an AED, what is the next step?
Resume chest compressions immediately
Analyze rhythm again
Check the patient's pulse for 30 seconds
Deliver a second shock right away
After a shock, you should resume chest compressions immediately to maintain blood flow and perfusion. Delaying compressions can reduce the effectiveness of the shock delivered.
Why is it important to minimize interruptions in chest compressions during CPR?
To improve rescue ventilation
To reduce rescuer fatigue
To maintain coronary perfusion pressure
To speed up defibrillator charging
Continuous compressions help maintain coronary perfusion pressure, which is critical for delivering oxygen-rich blood to the heart muscle. Frequent interruptions can lead to a drop in perfusion pressure.
How should AED pad size be selected for pediatric patients?
Based on patient weight and age
Based on chest circumference alone
Based on height only
Always use adult pads
Pediatric pads or attenuators are sized to deliver appropriate energy levels for children under a certain weight or age. Using the correct size helps ensure safe and effective defibrillation.
When performing two-rescuer CPR on an adult with an advanced airway in place, what is the recommended ventilation rate?
30 breaths per minute
2 breaths every 10 seconds
1 breath every 6 seconds
15 breaths per minute
With an advanced airway in place, rescuers deliver 1 breath every 6 seconds (about 10 breaths per minute) without pausing chest compressions. Continuous compressions maintain perfusion.
What is the recommended initial shock energy range for an adult using a biphasic AED?
50 to 70 joules
360 to 500 joules
200 to 360 joules
120 to 200 joules
Most biphasic AEDs are designed to deliver an initial shock of 120 to 200 joules to maximize efficacy while minimizing myocardial injury. Higher energy levels are reserved for subsequent shocks if needed.
Under which condition should you discontinue CPR on a patient?
When the patient shows signs of life
After 5 minutes of CPR
As soon as EMS arrives
After delivering three shocks
CPR should continue until the patient shows clear signs of life, such as normal breathing or purposeful movement. Discontinuing CPR before signs of life appears can reduce survival chances.
In a severely hypothermic adult (<30°C) found in ventricular fibrillation, how many shocks should you attempt before focusing on warming?
1 shock
3 shocks
No shocks until normothermic
5 shocks
Guidelines recommend attempting up to three defibrillation shocks in a severely hypothermic patient before delaying further attempts to focus on rewarming. Delaying after three tries acknowledges reduced drug metabolism and shock efficacy.
What effect does high electrode-skin impedance have on defibrillation efficacy?
Reduces the current delivered
Automatically increases shock energy
Has no effect on current
Increases the current delivered
High electrode - skin impedance reduces the amount of current that actually reaches the heart, thereby decreasing the effectiveness of defibrillation. Proper pad adhesion and skin preparation help lower impedance.
Which airway maneuver is recommended if a cervical spine injury is suspected during CPR?
Manual inline stabilization only
Jaw-thrust without head tilt
Triple airway maneuver
Head tilt - chin lift
The jaw-thrust maneuver opens the airway without moving the cervical spine, making it the recommended technique when a spinal injury is suspected. Head tilt - chin lift can cause spinal movement in these patients.
If pediatric AED pads are unavailable for a small child, what is the recommended pad placement using adult pads?
One pad on the abdomen and one on the back
One pad on the front center of the chest and one on the back
Standard adult anterior-lateral placement
Both pads on the left side of the chest
When pediatric pads are unavailable, placing one pad on the chest and the other on the back ensures the current passes through the smaller heart. Standard adult anterior-lateral placement may result in pad overlap.
When placing AED pads on a patient with an implanted pacemaker or ICD, what should you do?
Use only one pad to avoid interference
Place pads directly over the device
Do not use AED on these patients
Place pads at least 8 centimeters away from the device
Keeping AED pads at least 8 cm away from an implanted device prevents interference and reduces the risk of device damage. This spacing ensures effective current delivery through the myocardium.
