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.

A 3-year-old female has had severe diarrhea and vomiting for 4 days. She is now unresponsive with rapid, shallow respirations and thready radial pulses. Her heart rate is 160 beats/min, and her oxygen saturation is 88%. You should:
- A. Ventilate her with a bag-valve mask.
- B. Start chest compressions.
- C. Administer high-flow oxygen via a non-rebreathing mask.
- D. Place her in the recovery position.
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.
Which of the following is a more reliable indicator of perfusion in children than in adults?
- A. Blood pressure
- B. Heart rate
- C. Respiratory rate
- D. Capillary refill
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.
When assessing a 5-year-old boy with major trauma, his blood pressure is 70/40 mm Hg, and his pulse rate is 140 beats/min and weak. The child's blood pressure:
- A. indicates decompensated shock.
- B. reflects adequate compensation.
- C. suggests increased intracranial pressure.
- D. is appropriate based on his age.
Correct Answer: A
Rationale: In a 5-year-old boy with major trauma, a blood pressure of 70/40 mm Hg and a pulse rate of 140 beats/min, and weak, indicate decompensated shock. This presentation signifies inadequate perfusion, leading to compensatory mechanisms being overwhelmed, resulting in decompensated shock. Choice B is incorrect as the vital signs suggest the body is unable to adequately compensate for the trauma. Choice C is incorrect as the vital signs are more indicative of shock rather than increased intracranial pressure. Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.
How should you assist with the delivery of the baby's head?
- A. Grasping each side of the baby's head and gently pulling to facilitate delivery.
- B. Placing your fingers on the bony part of the skull and applying gentle pressure.
- C. Carefully rotating the baby's head to face up during delivery.
- D. Placing the palm of your hand firmly against the back of the baby's skull.
Correct Answer: B
Rationale: To assist with the delivery of the baby's head, the correct technique involves placing your fingers on the bony part of the skull and applying gentle pressure. This method helps guide the baby's head through the birth canal safely and effectively. Choices A, C, and D are incorrect. Grasping and pulling the baby's head, rotating the head, or placing the palm of your hand against the back of the baby's skull can potentially cause harm or complications during delivery.
Which of the following statements regarding febrile seizures in children is correct?
- A. They can occur even after a child has had a fever for longer than 24 hours.
- B. They can be caused by viral or bacterial meningitis.
- C. They do not typically occur on the first day of a fever.
- D. They typically last less than 15 minutes and often do not have a postictal phase.
Correct Answer: D
Rationale: The correct answer is D. Febrile seizures in children typically last less than 15 minutes and often do not have a postictal phase, meaning there is usually no prolonged recovery period or confusion after the seizure. They are commonly associated with the rapid rise in body temperature at the onset of a fever, rather than the duration of the fever itself. Choices A, B, and C are incorrect because febrile seizures can occur even after a child has had a fever for longer than 24 hours, they can be caused by viral or bacterial meningitis, and they do not have a typical pattern of occurring on the first day of a fever.
