Question:- 3. Summarize the factors that affect stroke volume: preload, aAerload, and contracFlity. Describe how each affects the end-diastolic volume/end-systolic volume. What happens to stroke volume when each (preload, aAerload, and contracFlity) is increased? 4. Summarize the events of the cardiac cycle. What are the 5 stages? What happens during each stage?

Time remaining: 00:09:43 Nursing Viva Voce Scenario You are working as a registered nurse in a community setting, buddied with a nursing student, Greg. You are assigned to care for Mrs Neda, who requires an International Normalised Ratio (INR) test. You note that Mrs Neda is taking warfarin (Coumadin) as part of the management of her atrial fibrillation. Greg asks you if you could explain the mechanism of action of warfarin (Coumadin) to him. Question 1:​Explain to Greg the mechanism of action of warfarin (Coumadin). Mrs Neda complains of gum bleeding when she brushes her teeth and asks you to explain why this is happening. Question 2:​Provide an explanation to Mrs Neda whybleeding is one of the side-effects of warfarin (Coumadin). Greg noted that Mrs Neda also takes an antidysrhythmic. Greg asks you why two drugs are needed. Question 3:​Explain to Greg why multiple drugs are given when a patient has atrial fibrillation. The INR comes back on the high side of normal. You speak…

QUESTION: 4. Discuss major causes of heart valvular defects

 Time remaining: 01:59:56 Nursing Kayla Christianson, CMA, has been employed six years by the cardiology practice of three physicians. She is a graduate of a CAAHEP-accredited school. Furthermore, Kayla received extensive hands-on training performing ECGs while doing her required externship. Kayla has completed an ECG ordered by Dr. Hsu for Mrs. Warner, a 76-year-old patient. Dr. Hsu, Kayla’s boss, telephoned her explaining that he was behind schedule doing rounds at the hospital. He asked her to do him a favor and interpret Mrs. Warner’s ECG, sign his name, and fax the report to Mrs. Warner’s referring internist, who is expecting the results. Given the scope of Kayla’s education, training, and years of experience as a CMA, would this “favor” fall within the AAMA guidelines of her responsibilities? Would any portion of Dr. Hsu’s request fall within the guidelines? If so, which portion(s)? Is an exception to these guidelines ever allowed? How should Kayla respond to Dr. Hsu?

10:37 O X O 10 l ll 40% As you are transporting the patient, you continue to reassess vital signs and perform another more complete neuro exam to see if there are any deficits, and to see if there is any change in symptoms over time. You note that the patient's pupils are 3 mm, equal and reactive to light. Her speech remains slightly slurred and she is slow to respond on some questions, so you check a blood glucose, which is 84 mg/dL. Hand grips and left-sided weakness remain the same throughout transport.
