Greta Balodis (patient)
One of Greta’s close friends from the Latvian club has a daughter who is a second year student nurse. Greta has asked if you can explain the pathophysiology of a Cerebrovascular Accident (stroke) and how it affects the central nervous system to her friend’s daughter, as she doesn’t understand and has an exam approaching. Greta has given her permission for you to use her as an example. Please explain the pathophysiology of a Cerebrovascular Accident (stroke) and how it affects the central nervous system using the correct medical and nursing terminology.

What is a hypothesis?

/in /by

Why is the sky blue? Why do bees sting? Why is the ocean salty? These are questions a young child may ask about the world based on his or her observations and experiences. As children grow older, their inquisitive nature may begin to fade. Anyone involved in the scientific process, however, must continually make observations and ask questions about his or her observations. In addition, scientists suggest possible answers to their questions and then test their ideas to determine if they are correct. This process is known as the scientific method.
The scientific method, however, does not answer every question about the universe. For example, it cannot answer questions such as “Is there a god?” or “What is the true meaning of life?” As you begin your exploration of biology this week, you consider the nature of science and how the scientific approach to the world differs from others, such as philosophical or spiritual approaches. Then, you apply this understanding by identifying a situation in which you can apply the scientific method and a situation in which you cannot.
To prepare for this:
Consider the question, “Can Science Cure the Common Cold?” Think of a few additional questions science could answer. How do you think science might find answers to these questions?
Consider how the scientific method tests ideas and attempts to find answers to questions. For example,
oWhat is a hypothesis?
oHow does an experiment test a hypothesis?
oWhy is the experimental process essential to science?
Review the articles in this week's Required Resources.
oIn the article “The Nature of Science,” note the characteristics of scientific inquirythat is, how scientists study phenomena to arrive at evidence-based conclusions.
oPay special attention to the Reality Check activity in the article “How Can We Tell Science from Non-Science?” Consider what distinguishes the scientific statements from the non-scientific ones.
With these thoughts in mind:
Write two or more paragraphs that distinguish the nature of science from non-science and that explain how the scientific method can be used to answer a question or solve a problem.
Your post should include the following:
Three characteristics of a scientific approach to the world
A real-life example of how the scientific method was or could be applied to solve a problem or answer a question
A real-life scenario that cannot be tested scientifically
References to at least two sources outside the Required Resources
All references cited in APA format

Include in your discussion an evaluation of the presence and effects of alteration in the homeostatic state secondary to gender, genetic, ethnic, and temporal variables.
Requirements:
Make sure all of the topics in the case study have been addressed.
Cite at least three sources; journal articles, textbooks or evidenced-based websites to support the content.
Two sources from the book and one other evidence-based reference no older than 3-5 years.

Case Study 4
APA format.
A 72-year-old man presents to the emergency department complaining of severe shortness of breath. He has long-standing poorly controlled hypertension and history of coronary artery disease and two myocardial infarctions. About 1 week before admission, he had an episode of substernal chest pain lasting approximately 30 minutes. Since then he has noted progressive shortness of breath to the point that he is now dyspneic on minimal exertion such as walking across the room. He notes a new onset of shortness of breath while lying down. He is only comfortable when propped up by three pillows. He is occasionally awakened from sleep acutely short of breath. On examination he is afebrile, with a blood pressure of 160/100 mm Hg, heart rate of 108/min, respiratory rate of 22/min, and oxygen saturation of 88% on room air. He is pale, cool, and diaphoretic. Jugular venous pressure is 10 cm H2O. Chest auscultation reveals rales in both lungs to the mid lung fields. Cardiac examination reveals tachycardia, with an audible S3 and S4. No murmurs or rubs are heard. Extremities are without edema. The ECG shows left ventricular hypertrophy and Q waves in the anterior and lateral leads, consistent with this patient’s history of hypertension and myocardial infarction. Chest x-ray film reveals bilateral fluffy infiltrates consistent with pulmonary edema. He is admitted to the ICU with a diagnosis of heart failure and possible myocardial infarction.
What are the four factors that account for almost all cases of pulmonary edema?
Which are probably responsible for this patient’s pulmonary edema?
