What is the MOST effective way to prevent cardiopulmonary arrest in a newborn?

Correct Answer: A

Rationale: The most effective way to prevent cardiopulmonary arrest in a newborn is to ensure effective oxygenation and ventilation. This is crucial in maintaining adequate oxygen supply and preventing respiratory distress or failure, which are significant factors leading to cardiopulmonary arrest. Providing appropriate ventilation support and oxygenation can help sustain the newborn's vital functions and reduce the risk of cardiopulmonary compromise.

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: C

Rationale: Gastric distention in infants and children can lead to a decrease in ventilatory volume. This occurs because the distended stomach can limit the movement of the diaphragm, reducing its ability to contract and expand the chest cavity effectively. As a result, the amount of air entering and leaving the lungs is decreased, impacting ventilation. Tracheal rupture, acute rupture of the diaphragm, and less effective chest compressions are not typically associated with gastric distention.

Correct Answer: B

Rationale: In a 3-year-old child with a sudden onset of respiratory distress and no recent illnesses or fever, the likely cause is a foreign body airway obstruction. Foreign body obstruction can lead to sudden respiratory distress without other preceding symptoms. It is crucial to consider this possibility and act promptly to clear the airway in such cases to prevent serious complications.

Correct Answer: B

Rationale: When dealing with a suspected case of SIDS, it is crucial to carefully inspect the environment in which the infant was found. This inspection can provide valuable information that may help determine the cause and support further investigation into the incident. By examining the surroundings, potential hazards or clues related to the sudden event may be identified, aiding in understanding the circumstances and potentially preventing similar incidents in the future.

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.
