1. 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.

2. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

3. 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.

4. 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.

5. The healthcare provider is assessing a newborn who is 2 hours old. Which finding requires immediate intervention?

• A. Acrocyanosis
• B. Respiratory rate of 60 breaths per minute
• C. Grunting with nasal flaring
• D. Heart rate of 140 beats per minute

Correct answer: C

Rationale: Grunting with nasal flaring is a concerning sign of respiratory distress in a newborn that can indicate inadequate oxygenation. This finding requires immediate intervention to ensure the newborn's respiratory status is stabilized and to prevent further complications. Prompt assessment and appropriate intervention are crucial in such cases to prevent respiratory compromise and potential deterioration. Acrocyanosis, which is bluish discoloration of the extremities, is a common finding in newborns and usually resolves on its own. A respiratory rate of 60 breaths per minute and a heart rate of 140 beats per minute are within normal ranges for a newborn and do not indicate immediate intervention is needed.
