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: D

Rationale: In this scenario, the 4-year-old boy with a tracheostomy tube is showing signs of respiratory distress, including intercostal retractions, a low heart rate, and decreased oxygen saturation. The gurgling sound indicates a possible airway obstruction. Correctly, the immediate action should be to carefully suction the tracheostomy tube. Suctioning can help clear any secretions or obstructions, thus improving the child's ability to breathe effectively. Ventilating through the tube, placing an oxygen mask over it, or removing and cleaning the tube would not address the potential obstruction and could worsen the respiratory distress.

Correct Answer: D

Rationale: The length-based resuscitation tape measure is designed to estimate a child's weight based on their length and can be used for children weighing up to 75 pounds. It is a reliable tool for pediatric weight estimation in emergency situations.

Correct Answer: C

Rationale: The ideal time to clamp and cut the umbilical cord is when it has stopped pulsating. This allows for the transfer of remaining blood from the placenta to the newborn, which can be beneficial for the baby's health and iron stores. Clamping the cord too early can deprive the newborn of this essential blood volume. Waiting for the pulsations to cease ensures that the baby receives the maximum benefits from delayed cord clamping.
