Correct Answer: C

Rationale: Inattention to the EMT's presence is a sign of altered mental status in a small child. When a child is not responsive or does not acknowledge the presence of the EMT, it could indicate a change in their mental status. This lack of attention or awareness may signify a neurological issue or other medical condition affecting the child's cognitive function.

Correct Answer: A

Rationale: Purple and yellow bruises on protected areas like the thighs are concerning as they indicate bruises in various stages of healing, which is a red flag for physical abuse. Bruises on the anterior tibial area or a child clinging to a parent are not specific signs of physical abuse. Siblings watching you is unrelated to the suspicion of physical abuse in this scenario.

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: B

Rationale: In this scenario, the appropriate action is to keep the newborn warm, ensure the mother receives oxygen if needed, and prepare for transport. The newborn is showing signs of central cyanosis (hands and feet being cyanotic), which can be due to various reasons, including inadequate oxygenation. Therefore, ensuring warmth and possible oxygen to the mother are important. Additionally, monitoring both the mother and baby during transport is crucial for their well-being.

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.
