What action should you take if a newborn's heart rate is 50 beats/min?
- A. Begin chest compressions.
- B. Reassess in 30 seconds.
- C. Administer blow-by oxygen.
- D. Start positive-pressure ventilations.
Correct Answer: D
Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

When assisting ventilations in a 4-year-old child with a bag-valve mask, what should the EMT do?
- A. Deliver each breath over 2 to 3 seconds.
- B. Ensure the appropriate mask size is used.
- C. Block the pop-off valve if needed to achieve adequate chest rise.
- D. Reassess the pulse rate after 60 seconds.
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.
Which of the following statements regarding 2-rescuer child CPR is correct?
- A. The chest should be compressed with one hand, and a compression-to-ventilation ratio of 30:2 should be used.
- B. The chest should not be allowed to fully recoil in between compressions.
- C. A compression-to-ventilation ratio of 15:2 should be used if an advanced airway is in place.
- D. Compress the chest with one or two hands to a depth equal to one-third the diameter of the chest.
Correct Answer: D
Rationale: During 2-rescuer child CPR, it is important to compress the chest with one or two hands to a depth equal to one-third the diameter of the chest. This technique ensures effective chest compressions are being delivered to help circulate blood and oxygenate the child's body. Choice A is incorrect because both hands should be used for chest compressions in 2-rescuer CPR. Choice B is incorrect as allowing the chest to fully recoil between compressions is essential to create negative pressure and facilitate blood flow back to the heart. Choice C is incorrect as the standard compression-to-ventilation ratio for child CPR is 30:2, regardless of whether an advanced airway is in place.
What is the appropriate ventilation rate for an apneic infant?
- A. 8 to 10 breaths/min.
- B. 10 to 12 breaths/min.
- C. 12 to 20 breaths/min.
- D. 20 to 30 breaths/min.
Correct Answer: C
Rationale: During resuscitation of an apneic infant, the appropriate ventilation rate is 12 to 20 breaths per minute. This rate helps provide adequate oxygenation and ventilation without causing harm to the infant. Choice A (8 to 10 breaths/min) is too low and may not provide sufficient ventilation. Choice B (10 to 12 breaths/min) is slightly below the recommended range, which may not be optimal for effective resuscitation. Choice D (20 to 30 breaths/min) is too high and may lead to overventilation and potential harm to the infant by causing hypocapnia.
When assessing a geriatric patient who has possibly experienced an acute ischemic stroke, which of the following questions would be MOST appropriate to ask?
- A. When did you first notice the symptoms?
- B. Do you have a history of high blood pressure?
- C. What medications do you take and why?
- D. Have you previously had a heart attack?
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.
Following an apparent febrile seizure, a 4-year-old boy is alert and crying. His skin is hot and moist. Appropriate treatment for this child includes:
- A. allowing the parents to transport the child.
- B. offering oxygen and providing transport.
- C. rapidly cooling the child in cold water.
- D. keeping the child warm and providing transport.
Correct Answer: B
Rationale: After a febrile seizure, the priority is to offer oxygen and provide transport to a medical facility. Oxygen may be necessary to ensure proper oxygenation, and medical evaluation is crucial to determine the cause of the seizure and prevent recurrence. Rapidly cooling the child in cold water is not recommended as it may lead to complications such as hypothermia. Keeping the child warm is also not indicated as the skin is already hot and moist. Therefore, offering oxygen and timely transportation to a healthcare facility is the most appropriate course of action. Allowing the parents to transport the child might delay necessary medical care, and keeping the child warm can exacerbate the existing heat. Rapidly cooling the child in cold water can lead to adverse effects, making it an inappropriate choice.
