For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

Encourage the victim to keep coughing instead of immediately intervening.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

Excessive ventilation can cause complications like gastric inflation.

For single-rescuer infant CPR, use two fingers just below the nipple line to perform compressions.

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

A firm surface is needed to ensure effective compressions.

Breaths should be delivered over 1 second each to produce visible chest rise.

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

For two-rescuer infant CPR, the correct compression-to-ventilation ratio is 15:2.

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

The first step is to turn on the AED before attaching pads and following voice prompts.

An AED is used on patients who are unresponsive, pulseless, and not breathing.

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

The best method is to tap the patient and shout to assess for responsiveness.

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

Adult chest compressions should be at least 2 inches (5 cm) deep.

Encourage the victim to keep coughing instead of immediately intervening.

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

Rescue breathing is the correct response if the patient has a pulse but no breathing.

Agonal gasps are not normal breathing and should not delay CPR.

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

The first step after turning on an AED is attaching the electrode pads.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Effective compressions allow full chest recoil, ensuring proper circulation.

The first step after turning on an AED is attaching the electrode pads.

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

Naloxone should only be administered if opioid overdose is suspected.

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

Ventilations should be given every 6 seconds when an advanced airway is in place.

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

Pulse checks should be limited to 10 seconds to avoid delaying CPR.

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

Equal chest rise and fall confirms proper ventilation and airway placement.

The recommended compression rate is 100-120 compressions per minute.

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

Ventilations should be given every 6 seconds when an advanced airway is in place.

If the AED does not advise a shock, rescuers should immediately resume CPR.
