What is the MOST effective way to prevent cardiopulmonary arrest in a newborn?

Correct Answer: A

Rationale: The most effective way to prevent cardiopulmonary arrest in a newborn is to ensure effective oxygenation and ventilation. This is crucial in maintaining adequate oxygen supply and preventing respiratory distress or failure, which are significant factors leading to cardiopulmonary arrest. Providing appropriate ventilation support and oxygenation can help sustain the newborn's vital functions and reduce the risk of cardiopulmonary compromise.

Correct Answer: B

Rationale: The most appropriate position for a mother in labor with a prolapsed umbilical cord is supine with hips elevated. This position helps reduce pressure on the cord, preventing further complications and ensuring optimal blood flow to the fetus.

Correct Answer: B

Rationale: The correct approach to prevent cardiac arrest in infants and small children is to ensure adequate ventilation. In these cases, maintaining proper oxygenation and ventilation is crucial for sustaining life. Providing immediate transport, keeping the child warm, or avoiding upsetting the child are important considerations but ensuring adequate ventilation takes precedence in preventing cardiac arrest and supporting the child's vital functions.

Correct Answer: B

Rationale: In a newborn with a heart rate below 100 beats/min, the most appropriate initial management is to initiate positive-pressure ventilations. This helps support the newborn's respiratory effort and oxygenation in the setting of a low heart rate, ensuring adequate oxygen supply to vital organs. Assessing the skin condition and color, starting chest compressions, or providing blow-by oxygen are not the priority in this scenario where respiratory support is crucial.

Correct Answer: C

Rationale: In a child with increased work of breathing, a high-pitched sound during inhalation, and a high fever, upper airway obstruction should be suspected. The child's condition may require immediate ventilation assistance to ensure adequate oxygenation and ventilation. Therefore, the most immediate concern in this scenario is to assess the need for ventilation assistance.

Correct Answer: C

Rationale: Nausea and vomiting are more common in children than adults following an isolated head injury. Children often present with gastrointestinal symptoms like nausea and vomiting after a head injury due to differences in physiological responses compared to adults.

Correct Answer: D

Rationale: Tilting the head back without hyperextending the neck is the safest way to open an infant's airway. Hyperextending the neck can potentially cause harm to the infant, making option D the most appropriate method for opening an infant's airway without suspected neck injury.

Correct Answer: D

Rationale: The appropriate ventilation rate for an infant with an advanced airway is 8 to 10 breaths per minute.

Correct Answer: C

Rationale: When performing two-rescuer CPR on a 4-year-old child, the appropriate technique involves 15 compressions to 2 ventilations. Compressions should be done by pressing the child's sternum with the heel of your hand. Ventilations should be given until visible chest rise occurs. This technique ensures effective CPR delivery for a child in need of resuscitation.
