A firm surface is needed to ensure effective compressions.

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

The correct compression depth for adult CPR is at least 2 inches (5 cm).

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

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

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

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

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

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

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

Rescue breaths should be given before starting chest compressions in drowning victims.

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

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

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

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

Excessive ventilation can cause complications like gastric inflation.

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

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

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

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

A firm surface is needed to ensure effective compressions.

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

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

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