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.

Correct Answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.

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: A

Rationale: After a febrile seizure, the recommended course of action is to provide supportive care and transport the child to a medical facility. Supportive care may include ensuring a safe environment, monitoring the child, and seeking medical evaluation to determine the underlying cause of the seizure and appropriate management.

Correct Answer: D

Rationale: When the top of the baby's head is visible (crowning) during transport, it indicates imminent delivery. In this situation, it is crucial to stop the ambulance and assist with the delivery. This ensures a safe delivery process for the mother and the baby. Waiting to arrive at the hospital or attempting to apply pressure to the baby's head can lead to complications. Allowing the head to deliver and checking for the cord's location is a necessary step during the delivery process, but the immediate priority is to assist in the safe delivery of the baby.
