What is the proper depth of chest compressions for a 9-month-old infant?
- A. 1/3 the diameter of the chest or about 1 1/2 inches.
- B. 1/4 the diameter of the chest or about 1 inch.
- C. 1/2 the diameter of the chest or about 2 inches.
- D. 1/3 the diameter of the chest or about 3/4 inch.
Correct Answer: A
Rationale: When performing chest compressions on a 9-month-old infant, the proper depth is 1/3 the diameter of the chest, which equates to approximately 1 1/2 inches. This depth is crucial for effective cardiopulmonary resuscitation (CPR) in infants. Choice B, which suggests 1/4 the diameter of the chest or about 1 inch, is incorrect as it does not provide the recommended depth for infants. Choice C, stating 1/2 the diameter of the chest or about 2 inches, is too deep and may cause harm to the infant. Choice D, mentioning 1/3 the diameter of the chest or about 3/4 inch, is also incorrect as it underestimates the required depth for effective chest compressions on a 9-month-old infant.

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.
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.
Which of the following signs would you expect to see in a child with respiratory failure?
- A. Slow, irregular breathing
- B. Flushed skin
- C. Strong cry
- D. Unconsciousness
Correct Answer: A
Rationale: In a child with respiratory failure, slow, irregular breathing is a common sign. Respiratory failure impairs the ability to exchange oxygen and carbon dioxide efficiently, leading to altered breathing patterns. Flushed skin, a strong cry, or unconsciousness may not be specific signs of respiratory failure and could be indicative of other conditions. Flushed skin may be a sign of fever or increased blood flow, a strong cry may indicate pain or distress, and unconsciousness can have various causes beyond respiratory failure.
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, it is important to offer oxygen and provide transport to a medical facility for further evaluation and management of the underlying cause. Oxygen may be needed in case of hypoxemia resulting from the seizure. 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 advisable as the priority is to prevent hyperthermia and provide necessary medical intervention by healthcare providers.
