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 pediatric assessment triangle is used to form a rapid, hands-off general impression of the child's condition without directly touching them. This visual assessment helps in identifying children who require immediate attention and further evaluation.

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: In cases where child abuse is suspected, the priority is the safety and well-being of the child. Advising the parents that the child needs to be transported for further evaluation and care is the appropriate initial step. This ensures that the child receives necessary medical attention while also addressing the suspicion of abuse through proper channels. It is essential to involve appropriate authorities and follow established procedures to protect the child and investigate any potential abuse further.

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.
