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.

General guidelines when assessing a 2-year-old child with abdominal pain and adequate perfusion include:
- A. placing the child supine and palpating the abdomen.
- B. separating the child from the parent to ensure a reliable examination.
- C. examining the child in the parent's arms.
- D. palpating the painful area of the abdomen first.
Correct Answer: C
Rationale: When assessing a 2-year-old child with abdominal pain and adequate perfusion, it is essential to examine the child in the parent's arms. This approach can help maintain the child's comfort, keep them calm, and increase their cooperation during the assessment. Placing the child supine and palpating the abdomen (Choice A) can be distressing and uncomfortable for the child. Separating the child from the parent (Choice B) may cause additional stress and hinder the examination process. Palpating the painful area first (Choice D) can lead to increased discomfort and resistance from the child.
Which of the following statements regarding sudden infant death syndrome (SIDS) is correct?
- A. Death as a result of SIDS can occur at any time of the day or night.
- B. Certain cases of SIDS are predictable and therefore preventable.
- C. Most cases of SIDS occur in infants younger than 6 months.
- D. SIDS is uncommon in infants older than 1 year of age.
Correct Answer: A
Rationale: The correct answer is A. SIDS can occur at any time of the day or night, although it most commonly occurs during sleep. SIDS is sudden and unpredictable, making it challenging to prevent in all cases. While most cases occur in infants younger than 6 months, it is not limited to this age group. SIDS is not uncommon in infants older than 1 year of age, although less common than in younger infants.
What are the MOST important initial steps in assessing and managing a newborn?
- A. Drying and warming the infant, obtaining an APGAR score.
- B. Clearing the airway, keeping the infant warm.
- C. Suctioning the airway, obtaining a heart rate.
- D. Keeping the infant warm, counting respirations.
Correct Answer: B
Rationale: The most crucial initial steps in assessing and managing a newborn involve clearing the airway to ensure proper breathing and keeping the infant warm to maintain body temperature. Airway clearance helps prevent respiratory distress, while warmth is essential to prevent hypothermia, a common issue in newborns. These steps are vital in the immediate care of a newborn to support their transition to extrauterine life and ensure their well-being. Choice A is incorrect because obtaining an APGAR score is important but not as critical as clearing the airway. Choice C is incorrect as suctioning the airway is not always necessary and obtaining a heart rate is secondary to ensuring a clear airway and warmth. Choice D is incorrect because counting respirations is not as immediate and crucial as clearing the airway.
Your assessment of a 5-year-old child reveals that he is unresponsive with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Treatment for this child should include:
- A. high-flow oxygen via non-rebreathing mask and rapid transport.
- B. assisted ventilation with a bag-mask device and rapid transport.
- C. positive-pressure ventilation, chest compressions, and rapid transport.
- D. back slaps and chest thrusts while attempting artificial ventilations.
Correct Answer: C
Rationale: In a 5-year-old child who is unresponsive with severe bradycardia and bradypnea, the priority is to provide positive-pressure ventilation to support breathing and perform chest compressions to support circulation. This child is in cardiac arrest, and the recommended treatment according to pediatric basic life support guidelines involves a combination of positive-pressure ventilation and chest compressions to maintain oxygenation and circulation. Rapid transport to a medical facility for further advanced care is crucial in this critical situation. Choices A, B, and D are incorrect because high-flow oxygen via non-rebreathing mask, assisted ventilation with a bag-mask device, and back slaps with chest thrusts are not sufficient in a cardiac arrest situation where the child requires immediate positive-pressure ventilation and chest compressions to maintain oxygenation and circulation.
What is the main function of the uterus?
- A. Dilate and expel the baby from the cervix.
- B. House the fetus as it grows for 40 weeks.
- C. Provide a cushion and protect the fetus from infection.
- D. Provide oxygen and other nutrients to the fetus.
Correct Answer: B
Rationale: The main function of the uterus is to house and nurture the growing fetus for approximately 40 weeks during pregnancy. It provides the necessary environment for the fetus to develop and grow until it is ready for birth. Choice A is incorrect as the cervix, not the uterus, dilates during labor to allow the baby to pass through. Choice C is incorrect as while the uterus does provide a protective environment, its primary function is not to act as a cushion. Choice D is incorrect as the placenta, not the uterus, is responsible for providing oxygen and nutrients to the fetus.
