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 ventilating an apneic 3-year-old child with a bag-valve mask device, what is the MOST important action to take?
- A. Avoid hyperventilation and ensure adequate chest rise.
- B. Squeeze the bag with both hands and use a pediatric mask.
- C. Immediately insert an oropharyngeal airway.
- D. Provide one breath every 3 to 5 seconds.
Correct Answer: A
Rationale: When ventilating an apneic child, the most important action is to avoid hyperventilation and ensure adequate chest rise. Hyperventilation can lead to decreased cardiac output and increased intracranial pressure. Adequate chest rise confirms effective ventilation and minimizes the risk of complications. Choice B is incorrect because using both hands to squeeze the bag may not ensure proper ventilation and can lead to complications. Choice C is incorrect as inserting an oropharyngeal airway is not the initial action in ventilating an apneic child with a bag-valve mask. Choice D is incorrect as providing ventilations every 3 to 5 seconds may not be appropriate for effective ventilation in a pediatric patient.
A 30-year-old woman has severe lower abdominal pain and light vaginal bleeding. She tells you that her last menstrual period was 2 months ago. On the basis of these findings, you should suspect:
- A. a normal pregnancy.
- B. a ruptured ovarian cyst.
- C. an ectopic pregnancy.
- D. a spontaneous abortion.
Correct Answer: C
Rationale: Severe lower abdominal pain, light vaginal bleeding, and a history of missed periods are concerning for an ectopic pregnancy. The absence of a normal menstrual period along with these symptoms raises suspicion for an ectopic pregnancy, which requires immediate medical attention due to the risk of rupture and life-threatening complications. A normal pregnancy would typically present with different symptoms such as a positive pregnancy test and typical signs of early pregnancy. A ruptured ovarian cyst may present with similar symptoms but typically lacks the history of missed periods. A spontaneous abortion usually involves heavier bleeding and tissue passage, which is not described in this scenario.
Which of the following injuries is MOST indicative of child abuse?
- A. Multiple bruises to the shins
- B. Burned hand with splash marks
- C. Small laceration to the chin
- D. Bruising to the upper back
Correct Answer: D
Rationale: Bruising to the upper back is more suspicious for child abuse compared to the other listed injuries. In young children, injuries like bruises to the upper back are less likely to be accidental and may raise concerns about physical abuse. The upper back is an area less prone to accidental injuries during play or falls. Multiple bruises to the shins are common in active children. A burned hand with splash marks may suggest accidental burns. A small laceration to the chin is also a common injury from falls in children. Therefore, the bruising on the upper back is more concerning for possible child abuse.
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.
Which of the following findings is abnormal?
- A. Rapid, irregular breathing in a newly born infant
- B. Heart rate of 80 beats/min in a 3-month-old infant
- C. Respiratory rate of 26 breaths/min in a 2-year-old child
- D. Systolic BP of 100 mm Hg in a 10-year-old child
Correct Answer: B
Rationale: A heart rate of 80 beats per minute in a 3-month-old infant is abnormally low for that age group and could indicate underlying health issues. The normal heart rate for a 3-month-old infant is typically higher, around 100-150 beats per minute. Therefore, this finding stands out as abnormal and warrants further evaluation. Choice A is not necessarily abnormal in a newly born infant as irregular breathing patterns can be common during the neonatal period. Choice C falls within the normal respiratory rate range for a 2-year-old child, which is around 20-30 breaths per minute. Choice D reflects a systolic blood pressure value within the normal range for a 10-year-old child, which is typically around 90-110 mm Hg.
