A. The correct compression depth for infants during pediatric BLS is approximately 1 inch (2.5 cm).

B. 1.5 inches (4 cm) is the correct compression depth for children (ages 1 to puberty).

C. 2 inches (5 cm) is the correct compression depth for adult patients.

D. 2.5 inches (6.5 cm) is not the recommended compression depth for any age group in BLS.

A. Head tilt-chin lift is used for older children and adults, not for neonates.

B. Jaw thrust is the recommended maneuver to open the airway in neonates to avoid putting pressure on the soft tissues of the neck.

C. Neck extensionof the head is not appropriate maneuvers for neonatal airway management.

D. Hyperextension of the head is not appropriate maneuvers for neonatal airway management.

A. Decreased heart rate indicates ineffective ventilation and is a sign of inadequate oxygenation.

B. Cyanosis suggests inadequate oxygenation and is not a sign of effective ventilation.

C. Chest movement and a rising heart rate are signs of effective ventilation in a newborn during neonatal resuscitation.

D. Gasping respirations are not a reliable indicator of effective ventilation and may indicate cardiac arrest.

A. 15:2 is the compression-to-ventilation ratio for two-rescuer infant CPR.

B. The correct compression-to-ventilation ratio for one-rescuer infant CPR is 30:2.

C. 30:1 is the compression-to-ventilation ratio for one-rescuer adult CPR.

D. 5:1 is not a standard compression-to-ventilation ratio for any age group in CPR.

A. 1 inch (2.5 cm) is the recommended compression depth for infants during pediatric BLS.

B. The correct compression depth for newborns during neonatal resuscitation is approximately 1.5 inches (4 cm).

C. 2 inches (5 cm) is the correct compression depth for adult patients.

D. 2.5 inches (6.5 cm) is not the recommended compression depth for any age group in BLS.

A. Administering positive-pressure ventilation is the initial step in neonatal resuscitation for a newborn not breathing or having a heart rate below 100 beats per minute.

B. Initiating chest compressions is the next step if positive-pressure ventilation is not effective.

C. Administering epinephrine is part of the advanced steps in neonatal resuscitation after positive-pressure ventilation and chest compressions.

D. Inserting an advanced airway device is part of the advanced steps in neonatal resuscitation after positive-pressure ventilation, chest compressions, and administering epinephrine.

A. Naloxone is used to reverse opioid overdose and is not indicated for bradycardia in neonatal resuscitation.

B. Atropine is used in neonatal resuscitation to treat bradycardia and increase the heart rate.

C. Epinephrine is used in neonatal resuscitation for severe bradycardia or cardiac arrest not responding to ventilation and chest compressions.

D. Albuterol is a bronchodilator and is not indicated for bradycardia in neonatal resuscitation.

A. 60-80 compressions per minute is the recommended rate of chest compressions for older children and adults in CPR.

B. 80-100 compressions per minute is the recommended rate of chest compressions for infants in CPR.

C. The recommended rate of chest compressions in neonatal resuscitation is 100-120 compressions per minute.

D. 120-140 compressions per minute is not a standard rate of chest compressions in neonatal resuscitation.

A. Head tilt-chin lift is used for older children and adults, not for newborns.

B. Jaw thrust is the recommended maneuver to open the airway in newborns to avoid putting pressure on the soft tissues of the neck.

C. Neck extension and D. Hyperextension of the head are not appropriate maneuvers for newborn airway management.

A. The correct sequence of steps in neonatal resuscitation according to the American Heart Association guidelines is Airway, Breathing, Chest compressions, Drugs, and Defibrillation (if indicated).

B. Chest compressions are performed after airway and breathing interventions, not before.

C. Breathing and airway interventions are prioritized before chest compressions.

D. Defibrillation, if indicated, is performed after the initial steps of neonatal resuscitation, including airway, breathing, and chest compressions. Drugs are administered after defibrillation if necessary.
