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

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

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

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

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

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

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

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

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

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

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

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

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

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

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

Breathing assessment should take no more than 10 seconds to avoid delaying CPR.

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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

A firm surface is needed to ensure effective compressions.

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

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

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

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

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

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

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

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

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

A firm surface is needed to ensure effective compressions.

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

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

Naloxone should only be administered if opioid overdose is suspected.

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

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