Correct Answer: B

Rationale: In a scenario where a young child falls from a significant height like a second-story window, the primary injury is more likely to be to the head. This is because young children have proportionately larger head sizes compared to their body, making them more susceptible to head injuries in such falls. The chest (Choice A), lower extremities (Choice C), and abdomen (Choice D) are less likely to sustain the primary injury in this scenario, as the impact of the fall and the child's anatomy predispose the head to be the most affected area.

Correct Answer: A

Rationale: In a child with respiratory failure, slow, irregular breathing is a common sign. Respiratory failure impairs the ability to exchange oxygen and carbon dioxide efficiently, leading to altered breathing patterns. Flushed skin, a strong cry, or unconsciousness may not be specific signs of respiratory failure and could be indicative of other conditions. Flushed skin may be a sign of fever or increased blood flow, a strong cry may indicate pain or distress, and unconsciousness can have various causes beyond respiratory failure.

Correct Answer: D

Rationale: Allowing the chest to fully recoil between compressions is crucial during CPR to ensure proper blood flow. This action allows the heart to refill with blood, enhancing the effectiveness of compressions and circulation. Hyperventilating the patient can lead to decreased cardiac output and is not recommended. Attaching AED pads should be done as soon as possible in a pediatric cardiac arrest situation, ideally within 2 minutes. The correct compression-to-ventilation ratio for pediatric CPR is 30:2, focusing on high-quality compressions to provide adequate perfusion to vital organs.

Correct Answer: D

Rationale: When encountering a protruding limb during delivery, it is crucial to recognize this as an emergency situation. The correct action is to cover the limb with a sterile towel to prevent injury and transport the mother immediately to a medical facility. Attempting to push the limb back into the vagina or trying to manipulate the baby's position can be harmful and delay necessary medical intervention. Encouraging the mother to push and providing high-flow oxygen is not appropriate in this scenario as immediate transport is essential to ensure the safety of both the mother and the baby.
