Which of the following statements regarding SIDS is correct?

Correct Answer: C

Rationale: The correct statement regarding SIDS is that death usually occurs during sleep. Sudden Infant Death Syndrome (SIDS) is the unexpected death of a seemingly healthy infant, typically occurring during sleep. The exact cause of SIDS is not fully understood. While placing the baby on its back to sleep is a recommended preventive measure to reduce the risk of SIDS, it cannot guarantee prevention. Choice A is incorrect as SIDS is not limited to premature infants. Choice B is incorrect as SIDS is not primarily caused by child abuse.

Correct Answer: C

Rationale: When assisting ventilations in a 4-year-old child with a bag-valve mask, the EMT should block the pop-off valve if needed to achieve adequate chest rise. This action helps ensure effective ventilation and adequate oxygenation in the child. Blocking the pop-off valve allows for better control over the volume of air delivered and can help maintain positive pressure in the airway, assisting in improving oxygenation and ventilation in the child. Choices A, B, and D are incorrect because delivering each breath over 2 to 3 seconds is a general guideline but may need adjustment based on patient response, ensuring the appropriate mask size is important but not the primary concern in this scenario, and reassessing the pulse rate is not directly related to the ventilation technique being discussed.

Correct Answer: B

Rationale: In a scenario where a child presents with respiratory distress, wheezing, nasal flaring, retractions, and an oxygen saturation of 92%, the appropriate intervention is to administer high-flow oxygen. This helps to improve oxygenation and alleviate the respiratory distress the child is experiencing. Placing the child in a supine position can worsen their condition by affecting their ability to breathe effectively. Chest compressions are not indicated in this case as the child is not in cardiac arrest. Administering low-flow oxygen may not provide adequate oxygenation for a child in respiratory distress with a saturation of 92%. Therefore, the priority is to administer high-flow oxygen to improve oxygen levels and support the child's breathing.

Correct Answer: A

Rationale: The most appropriate question to ask when assessing a geriatric patient who may have experienced an acute ischemic stroke is when the symptoms were first noticed. This information is crucial for determining the time window for potential treatments like thrombolytic therapy, as prompt intervention is necessary for stroke management. Option B is not as relevant in the acute assessment of stroke, though important for overall health history. Option C is important but may not be as time-sensitive as determining symptom onset. Option D focuses on a different cardiac event, not directly related to the current concern of a possible stroke.

Correct Answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

Correct Answer: D

Rationale: Administering oxygen and massaging the uterus are appropriate interventions to manage postpartum bleeding. Oxygen helps support tissue perfusion, and uterine massage can aid in uterine contraction, controlling bleeding. These actions are indicated when the mother experiences moderate vaginal bleeding post-delivery, as described in the scenario. Careful monitoring for signs of shock should continue while these interventions are implemented to ensure the mother's condition remains stable. Choices A and B are incorrect because packing the vagina with sterile dressings is not recommended for postpartum bleeding unless it is severe and immediate action is needed, while massaging the uterus is a proactive approach and should not be delayed until signs of shock develop. Choice C is also incorrect as rapid transport is not the primary intervention in this scenario where the mother is conscious, alert, and stable, and the focus should be on immediate management of the bleeding.

Correct Answer: D

Rationale: Upon delivery of a newborn's head, the priority is to clear the airway to ensure proper breathing. Suctioning the mouth takes precedence over suctioning the nose or other actions to prevent potential airway obstruction. Choice D is the correct answer as it addresses the immediate need to maintain a clear airway for the newborn. Choices A, B, and C are not the correct actions to take at this moment as they do not directly address the crucial need to establish a clear airway for the newborn.

Correct Answer: A

Rationale: In a pediatric patient presenting with unresponsiveness, rapid, shallow respirations, thready pulses, high heart rate, and low oxygen saturation, the priority is to ensure adequate oxygenation. Ventilating the child with a bag-valve mask is crucial in this scenario to support her breathing and improve oxygenation, as indicated by her low oxygen saturation and respiratory distress. Starting chest compressions is not indicated as the child has a pulse. Administering high-flow oxygen via a non-rebreathing mask may not be as effective as providing positive pressure ventilation with a bag-valve mask in this situation. Placing her in the recovery position is not appropriate when the child is unresponsive and in respiratory distress.

Correct Answer: C

Rationale: Seizures in children most often result from febrile seizures, which are triggered by an abrupt rise in body temperature. Febrile seizures are common in young children, especially between the ages of 6 months to 5 years, and are usually associated with viral infections that cause a sudden spike in body temperature. Choices A, B, and D are incorrect because while infections, inflammatory processes, and high temperatures can sometimes lead to seizures, the most common cause of seizures in children is an abrupt increase in body temperature, known as febrile seizures.
