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: B

Rationale: When dealing with a suspected case of SIDS, it is crucial to carefully inspect the environment in which the infant was found. This inspection can provide valuable information that may help determine the cause and support further investigation into the incident. By examining the surroundings, potential hazards or clues related to the sudden event may be identified, aiding in understanding the circumstances and potentially preventing similar incidents in the future.

Correct Answer: B

Rationale: The presentation of wheezing, widespread hives, and facial edema is consistent with an allergic reaction. These symptoms indicate a systemic response to an allergen, triggering respiratory distress and skin manifestations.

Correct Answer: C

Rationale: When inserting an oropharyngeal airway in a small child, it is crucial to depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue. This technique helps in maintaining an open airway and preventing obstruction by the tongue. Placing the airway with the curve facing the roof of the mouth or using a smaller size is not recommended for small children, as it may not effectively keep the airway patent. The tongue-jaw lift maneuver is not the preferred method for inserting an oropharyngeal airway in small children.

Correct Answer: C

Rationale: In a pediatric patient with respiratory distress, a non-rebreathing mask with a flow rate set at 6 to 8 L/min is the most effective way to deliver oxygen. This method ensures a high concentration of oxygen is delivered to the child, aiding in improving oxygen saturation levels. In this scenario, the mother can assist in holding the mask to maintain comfort and cooperation in the child while ensuring proper oxygen delivery.
