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 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: D

Rationale: During the assessment of a 30-year-old female in labor, the EMT should be aware that delivery is imminent if she is crowning. Crowning indicates that the baby's head is visible at the vaginal opening, signaling that the birth is progressing rapidly and the baby will soon be delivered. This is a critical moment that requires preparedness for the birth process and ensuring a safe delivery environment. Choice A is incorrect because asking the mother when she is expecting to deliver is not relevant when the baby's head is visible at the vaginal opening. Choice B is incorrect as obtaining the patient's medical history is essential for providing appropriate care. Choice C is incorrect because determining the stage of labor by examining the patient is important but recognizing crowning indicates that delivery is imminent and requires immediate action.

Correct Answer: D

Rationale: Upon delivery of a newborn's head, the priority is to clear the airway to ensure proper breathing. Suctioning the mouth takes precedence over suctioning the nose or other actions to prevent potential airway obstruction. Choice D is the correct answer as it addresses the immediate need to maintain a clear airway for the newborn. Choices A, B, and C are not the correct actions to take at this moment as they do not directly address the crucial need to establish a clear airway for the newborn.

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: 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: C

Rationale: In a breech presentation, where the baby's buttocks or feet present first, there is an increased risk of the umbilical cord slipping down alongside or below the presenting part, leading to a prolapsed umbilical cord. This is a serious complication that can compromise fetal blood flow and oxygenation, necessitating prompt intervention to prevent adverse outcomes. Choices A, B, and D are less likely to occur in conjunction with a breech presentation. Vertex presentation is the normal head-first presentation, maternal hypertension is a separate condition that may not be directly related to fetal presentation, and premature rupture of the amniotic sac can happen independently of the baby's presentation.

Correct Answer: B

Rationale: In obstetrics, gravida indicates the number of pregnancies, including the current one. Para indicates the number of pregnancies carried to viability (20 weeks or more). Since the patient has been pregnant twice but only carried one pregnancy past 20 weeks, her obstetric history should be documented as gravida 2, para 0. The miscarriage at 19 weeks does not contribute to the para count. Choice A (gravida 2, para 1) would indicate that she has had two pregnancies with one resulting in a live birth, which is incorrect. Choice C (gravida 1, para 1) would indicate that she has had one pregnancy with one live birth, which does not reflect her obstetric history. Choice D (gravida 0, para 2) would indicate that she has never been pregnant past 20 weeks, which is also inaccurate.

Correct Answer: D

Rationale: When encountering a protruding limb during delivery, it is crucial to recognize this as an emergency situation. The correct action is to cover the limb with a sterile towel to prevent injury and transport the mother immediately to a medical facility. Attempting to push the limb back into the vagina or trying to manipulate the baby's position can be harmful and delay necessary medical intervention. Encouraging the mother to push and providing high-flow oxygen is not appropriate in this scenario as immediate transport is essential to ensure the safety of both the mother and the baby.
