Correct Answer: B

Rationale: The correct approach to prevent cardiac arrest in infants and small children is to ensure adequate ventilation. In these cases, maintaining proper oxygenation and ventilation is crucial for sustaining life. Providing immediate transport, keeping the child warm, or avoiding upsetting the child are important considerations but ensuring adequate ventilation takes precedence in preventing cardiac arrest and supporting the child's vital functions.

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: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.

Correct Answer: B

Rationale: When assessing for a pulse in an unresponsive 6-month-old patient, the brachial artery is the recommended site for palpation. This is because the brachial artery is easily accessible and provides a reliable indication of the patient's circulatory status in infants.

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.
