Coursera 上的 “NREMT 国家注册急救医疗技术员考试” 课程旨在帮助学员为 NREMT 考试做准备。课程涵盖了急救医疗技术员 (EMT) 实践中的关键概念和技能，并通过一系列示例问题来巩固学习。 **课程内容亮点包括：** * **人工通气：** 课程通过示例问题，重点讲解了在非创伤患者中使用袋阀面罩 (BVM) 进行人工通气的正确步骤，包括体位调整、气道辅助器使用和面罩选择。 * **氧疗：** 针对有 emphysema 病史的患者，课程探讨了氧疗的禁忌症和适用时机，特别提到了“迟缓性低通气”（hypoxic drive）的概念，强调了在某些情况下，高流量氧气可能导致患者呼吸停止。 * **呼吸评估：** 课程阐述了评估呼吸是否不足的重要性，指出过快或过慢的呼吸频率、呼吸努力增加以及呼吸深度异常（过深或过浅）都可能指示呼吸存在问题。 * **常见病症鉴别：** 课程通过临床场景，引导学员学习初步判断患者病症，例如通过评估腿部肿胀、脉搏、皮肤状况和肺部听诊，来鉴别是深静脉血栓、动脉闭塞、动脉粥样硬化还是慢性心力衰竭。 * **血液循环路径：** 课程明确了血液通过心脏和肺部的正确循环路径，从腔静脉进入右心房，再到右心室，然后进入肺部，再经肺静脉回到左心房，最后到左心室，再通过主动脉泵出。 * **老年患者症状：** 课程指出老年患者的呼吸困难可能由多种原因引起，包括心力衰竭、心肌梗死或更广泛的心脏损伤。 总而言之，该课程通过实际案例和关键知识点的解析，为未来的 EMT 考生提供了扎实的理论基础和临床思维的训练。
Sample Questions:The first step in artificial ventilation with a bagvalve-mask unit in patients with no suspected trauma is to:Position the mask correctly on the face using both hands.Place the patient's head in a hyperextended, sniffing position.Insert an airway adjunct and select the correct mask size.Have an assistant squeeze the bag until the patient's chest rises.A 70-year-old patient is complaining of shortness of breath. She has a history of emphysema. You shouldWithhold oxygen, since these patients do not respond to oxygen.Withhold oxygen, because you could eliminate the hypoxic drive.Administer oxygen, because in most cases, the hypoxic drive will not be a problem.Withhold oxygen, because these patients become apneic if they receive high-flow oxygen.Which statement about inadequate breathing is correct?A breathing rate that is either too fast or too slow may indicate inadequate breathing.Inadequate breathing is much less common in small children than in older adults.Increased effort of breathing is often a normal sign and is not associated with inadequate breathing.A patient breathing very deeply or very shallowly is compensating for an abnormal respiratory rate.You are called to a nursing home for a patient with swelling to her legs. Upon arrival, you find a 76-year-old patient sitting in a wheelchair. Assessment confirms pitting edema to both lower legs. You are able to palpate a dorsalis pedal pulse bilaterally. Her skin is warm, pink, and dry. Her lungs are clear bilaterally. Which of the following conditions do you suspect?Deep vein thrombosis.Bilateral acute arterial occlusion.Atherosclerosis.Chronic CHF.The correct flow of blood through the heart and lungs is…?Inferior/superior vena cave, right atrium, right ventricle, lungs, left atrium, left ventricle, aortaAorta, left atrium, left ventricle, lungs, right atrium, right ventricle, Inferior/superior vena caveInferior/superior vena cave, right atrium, right ventricle, aorta, lungs, left atrium, left ventricleRight atrium, right ventricle, Inferior/superior vena cave, lungs, aorta, left ventricle, left atriumYour patient is an 80-year old male with shortness of breath. Which of the following could your patient be suffering from?Congestive heart failureA myocardial infarctionCardiac compromiseAll of the above
