You are treating a 5-year-old child who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. Supplemental oxygen has been given, and you have elevated his lower extremities. En route to the hospital, you note that his work of breathing has increased. You should:

Correct Answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.

Correct Answer: B

Rationale: Dehydration is the most common cause of shock in infants and children. In children, the body's fluid reserves are smaller compared to adults, making them more susceptible to dehydration, which can lead to shock if not promptly addressed. Severe allergic reactions, accidental poisoning, and cardiac failure can also cause shock, but dehydration is the most frequent cause in this age group.

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.

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: 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: C

Rationale: Expiratory grunting is a significant sign of inadequate breathing and respiratory distress in infants. It indicates that the infant is struggling to exhale properly, which can be a sign of various respiratory issues, including lung problems or airway obstruction. Monitoring and recognizing this sign promptly can help in providing timely interventions to support the infant's breathing and prevent further complications.

Correct Answer: D

Rationale: In this scenario, the 4-year-old boy with a tracheostomy tube is showing signs of respiratory distress, including intercostal retractions, a low heart rate, and decreased oxygen saturation. The gurgling sound indicates a possible airway obstruction. Correctly, the immediate action should be to carefully suction the tracheostomy tube. Suctioning can help clear any secretions or obstructions, thus improving the child's ability to breathe effectively. Ventilating through the tube, placing an oxygen mask over it, or removing and cleaning the tube would not address the potential obstruction and could worsen the respiratory distress.

Correct Answer: B

Rationale: In cases of drowning, it is crucial to assess for a carotid pulse for no more than 10 seconds to determine if chest compressions are needed. This quick assessment helps determine the next steps in providing appropriate care to the patient. Performing chest compressions without confirming the need may not be beneficial and could potentially harm the patient if unnecessary.

Correct Answer: A

Rationale: The EMT may be required to deliver a baby at the scene when external factors like a tornado have blocked the only route to the hospital, making it impossible to reach the medical facility in time for delivery. In such emergencies, the EMT must be prepared to manage the childbirth process until further medical assistance can be obtained.
