A 5-year-old boy was struck by a car when he ran out into the street. When you arrive at the scene and approach the child, you see him lying supine approximately 15 feet from the car. Based on the child's age and mechanism of injury, which of the following should you suspect to be his PRIMARY injury?

Correct Answer: D

Rationale: Given the mechanism of injury and the distance the child was thrown, a primary pelvic injury should be suspected due to the high impact and force. The pelvis is a common site for significant injury in such cases, and the distance the child was thrown indicates a high-energy impact that could lead to pelvic fractures or injuries.

Correct Answer: D

Rationale: For a responsive 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color, the appropriate treatment includes providing supplemental oxygen and arranging for transport to a healthcare facility. Oxygen helps alleviate the respiratory distress, and transport ensures the child receives further evaluation and care by healthcare professionals. Back slaps and subdiaphragmatic thrusts are not recommended for a child with a mild airway obstruction and normal skin color, as these interventions are typically reserved for more severe cases of airway obstruction.

Correct Answer: A

Rationale: The Apgar score is a rapid assessment tool to evaluate the newborn's transition to life outside the womb. The Apgar score is based on five components: heart rate (>100 bpm), respiratory effort (rapid breathing), muscle tone (resisting leg straightening), reflex irritability (crying when feet are flicked), and color (cyanosis to extremities). The described findings match a score of 9, indicating good overall condition and adaptation to extrauterine life.

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: B

Rationale: In a newborn with a heart rate below 100 beats/min, the most appropriate initial management is to initiate positive-pressure ventilations. This helps support the newborn's respiratory effort and oxygenation in the setting of a low heart rate, ensuring adequate oxygen supply to vital organs. Assessing the skin condition and color, starting chest compressions, or providing blow-by oxygen are not the priority in this scenario where respiratory support is crucial.

Correct Answer: D

Rationale: In cases of sexual assault, it's important to respect the patient's wishes and provide a female EMT to attempt the assessment if the patient prefers.

Correct Answer: C

Rationale: Placing sterile dressings into the vagina is not an appropriate treatment for severe vaginal bleeding. The correct approach involves applying pressure to the external vaginal area to control bleeding, covering the vagina with a trauma dressing to help with compression, administering high concentrations of oxygen to support oxygenation, and keeping the patient warm with blankets to prevent hypothermia. Placing sterile dressings into the vagina can introduce foreign material, increase the risk of infection, and obstruct proper wound management, making it an incorrect treatment option in this scenario.

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: C

Rationale: After the baby's head delivers, it is typically tilted posteriorly to one side to help facilitate the delivery of the shoulders. This positioning is important for the safe and smooth delivery of the baby.
