Correct Answer: B

Rationale: The most crucial initial steps in assessing and managing a newborn involve clearing the airway to ensure proper breathing and keeping the infant warm to maintain body temperature. Airway clearance helps prevent respiratory distress, while warmth is essential to prevent hypothermia, a common issue in newborns. These steps are vital in the immediate care of a newborn to support their transition to extrauterine life and ensure their well-being. Choice A is incorrect because obtaining an APGAR score is important but not as critical as clearing the airway. Choice C is incorrect as suctioning the airway is not always necessary and obtaining a heart rate is secondary to ensuring a clear airway and warmth. Choice D is incorrect because counting respirations is not as immediate and crucial as clearing the airway.

Correct Answer: C

Rationale: In a 5-year-old child who is unresponsive with severe bradycardia and bradypnea, the priority is to provide positive-pressure ventilation to support breathing and perform chest compressions to support circulation. This child is in cardiac arrest, and the recommended treatment according to pediatric basic life support guidelines involves a combination of positive-pressure ventilation and chest compressions to maintain oxygenation and circulation. Rapid transport to a medical facility for further advanced care is crucial in this critical situation. Choices A, B, and D are incorrect because high-flow oxygen via non-rebreathing mask, assisted ventilation with a bag-mask device, and back slaps with chest thrusts are not sufficient in a cardiac arrest situation where the child requires immediate positive-pressure ventilation and chest compressions to maintain oxygenation and circulation.

Correct Answer: D

Rationale: When assessing a small child's level of responsiveness, the most appropriate method is to tap the child and shout, 'Are you okay?' This approach is more likely to elicit a response from the child, providing a direct assessment of their level of consciousness and responsiveness. Palpating for a radial pulse (Choice A) is not the most direct method for assessing responsiveness in a child. Shouting at the child (Choice B) may startle them and not provide an accurate assessment. Asking the parent (Choice C) does not directly evaluate the child's responsiveness.

Correct Answer: B

Rationale: To assist with the delivery of the baby's head, the correct technique involves placing your fingers on the bony part of the skull and applying gentle pressure. This method helps guide the baby's head through the birth canal safely and effectively. Choices A, C, and D are incorrect. Grasping and pulling the baby's head, rotating the head, or placing the palm of your hand against the back of the baby's skull can potentially cause harm or complications during delivery.

Correct Answer: D

Rationale: During 2-rescuer child CPR, it is important to compress the chest with one or two hands to a depth equal to one-third the diameter of the chest. This technique ensures effective chest compressions are being delivered to help circulate blood and oxygenate the child's body. Choice A is incorrect because both hands should be used for chest compressions in 2-rescuer CPR. Choice B is incorrect as allowing the chest to fully recoil between compressions is essential to create negative pressure and facilitate blood flow back to the heart. Choice C is incorrect as the standard compression-to-ventilation ratio for child CPR is 30:2, regardless of whether an advanced airway is in place.
