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:

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.

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.

Correct Answer: B

Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.

Correct Answer: C

Rationale: When encountering a situation where the umbilical cord is wrapped around a baby's neck upon delivery, the initial treatment should involve trying to remove the cord from around the neck gently. It is crucial to handle this situation delicately to avoid causing harm to the baby. Attempting to ease the cord over the baby's head without pulling or tightening can help prevent potential complications associated with cord compression. Choice A, clamping and cutting the umbilical cord, is not recommended as it can lead to abrupt deprivation of oxygen to the baby. Choice B, gently pulling on the cord, can worsen the situation by tightening the cord around the baby's neck. Choice D, keeping the cord moist and providing rapid transport, is not the immediate concern and does not address the potential risks of cord compression during delivery. Therefore, the priority is to carefully attempt to remove the cord from around the baby's neck to ensure a safe delivery.

Correct Answer: C

Rationale: Seizures in children most often result from febrile seizures, which are triggered by an abrupt rise in body temperature. Febrile seizures are common in young children, especially between the ages of 6 months to 5 years, and are usually associated with viral infections that cause a sudden spike in body temperature. Choices A, B, and D are incorrect because while infections, inflammatory processes, and high temperatures can sometimes lead to seizures, the most common cause of seizures in children is an abrupt increase in body temperature, known as febrile seizures.

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.

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.

Correct Answer: D

Rationale: Allowing the chest to fully recoil between compressions is crucial during CPR to ensure proper blood flow. This action allows the heart to refill with blood, enhancing the effectiveness of compressions and circulation. Hyperventilating the patient can lead to decreased cardiac output and is not recommended. Attaching AED pads should be done as soon as possible in a pediatric cardiac arrest situation, ideally within 2 minutes. The correct compression-to-ventilation ratio for pediatric CPR is 30:2, focusing on high-quality compressions to provide adequate perfusion to vital organs.

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.
