What is the appropriate technique for performing two-rescuer CPR on a 4-year-old child?

Correct Answer: C

Rationale: When performing two-rescuer CPR on a 4-year-old child, the appropriate technique involves 15 compressions to 2 ventilations. Compressions should be done by pressing the child's sternum with the heel of your hand. Ventilations should be given until visible chest rise occurs. This technique ensures effective CPR delivery for a child in need of resuscitation.

Correct Answer: C

Rationale: When inserting an oropharyngeal airway in a small child, it is crucial to depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue. This technique helps in maintaining an open airway and preventing obstruction by the tongue. Placing the airway with the curve facing the roof of the mouth or using a smaller size is not recommended for small children, as it may not effectively keep the airway patent. The tongue-jaw lift maneuver is not the preferred method for inserting an oropharyngeal airway in small children.

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: 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: 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: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: In two-rescuer child CPR, the correct compression depth is one third the diameter of the chest. This depth can be achieved by compressing the chest with one or two hands. It is crucial to follow the correct compression depth guideline to ensure effective chest compressions and circulation during CPR for a child.
