A 54-year-old woman wishes to establish care without specific complaints after her primary care physician retired. She stopped smoking (2 packs per day) 6 months ago after a close friend died of lung cancer. A radionuclide stress test two years ago was normal at 85% predicted heart rate with an LVEF 55%. She takes amlodipine for hypertension, and metformin for type 2 diabetes mellitus. She leads a sedentary lifestyle and does not note any functional limitations. Her blood pressure is 147/92 mm Hg and her pulse is 87 beats per minute. She is mildly overweight and has trace lower extremity edema. Her physical examination is otherwise normal.
Atenolol and glyburide are added to her medication regimen, and her blood pressure and glucose control improve by her next visit. Unfortunately, she returns several weeks later with new onset of shortness of breath with exertion and intermittent wheezing. She continues to sleep on two pillows for comfort. Her blood pressure is 137/84 and her pulse is 97 beats per minute. You are unable to appreciate any jugular venous distention or abnormal heart sounds, but you note mild wheezing bilaterally.
Based on the elevated level of BNP, your suspicion for heart failure is high.
The patient undergoes coronary angiography and is found to have a small right coronary artery with moderate disease not amenable to angioplasty or stenting. The left circumflex artery appears to be chronically occluded, and the mid-left anterior descending artery has a severe stenosis that is stented.
While evaluating the patient in the hospital, you discover that she started taking ibuprofen following a knee sprain. You recommend alternative analgesics that are less likely to affect her heart failure. She improves with heart failure treatment over the next few days, and is ready for discharge. Her blood pressure is 117/69 and her heart rate is 67. You review her blood chemistries and note that her serum sodium is 137 mmol/L, potassium 4.2 mmol/L, BUN 27 mg/dL, and creatinine 1.4 mg/dL.

Decision Analysis

...Decision Analysis: Decision analysis is a set of quantitative decision making techniques for decision situations in which uncertainty exists. Now, uncertainty can be classified into two ways/ types: 1. Subjective Probability: Subjective probability is the degree of belief to occurrence of the event. 2. Objective Probability: Objective probability is the probability which can be derived either based on historical occurrences or based on experimentation. Alternatively can be derived from statistical formula. Consistency requirement: If the probability of an event A is 0.65, then the probability of event B must be 0.35. i.e. P(A) + P(B) = 1 Mathematically, if A, B Є E Then A, B [pic] E A [pic]B = φ P(A) + P(B) = 1, which is called Consistency requirements. # Elements of Decision Problems: A decision problem is usually viewed as having four common elements 1. The alternative course of action: The alternative course of action involves two or more options or alternative course of action. One and only one of these alternatives must be selected. 2. The states of nature: The state of nature are factors that affect the outcome of a decision but are beyond control of the decision maker, such as rain, inflation, political development etc. 3. Payoff table: A payoff table is the combination for each possible combination of alternative course of action and state of nature...

...2.Decision Theory - Decision Tables and Decision Trees, Game Theory 2.1 Introduction and Basic Terms Decision theory represents a generalized approach to decision making. It enables the decision maker to analyze a set of complex situations with many alternatives and many different possible consequences to identify a course of action consistent with the basic economic and psychological desires of the decision maker Decision theory problems are characterized by the following: a decision criterion a list of alternatives a list of possible future events (states of nature) payoffs associated with each combination of alternatives and events the degree of certainty of possible future events There is a wide range of management decision problems. Among them there are capacity and order planning, product and service design, equipment selection, location planning, and so on. Some examples of alternatives and possible events for these alternatives are shown in Table 2.1. Alternatives To order 10, 11, … units of a product To make or to buy a product To buy or not to buy accident insurance Events Demand for the product may be 0, 1, … units The cost of making may be 20, 22, … $thousands An accident may occur, or may not occur Table 2.1 “Examples of Alternatives and Events” Various properties of decision problems enable a classification of decision problems.

Scientific Inquiry

...Scientific Inquiry Javier Bryon AIU Online Abstract By using the controlled experimental method we can prove or disprove hypothesis in question. During the experiment we can come to a conclusion on whether further experimentation is needed or other hypothesis need to be implemented to solve a question. Introduction Blue porch ceilings are quite prevalent along the east coast, there are many theories as to why, from keeping evil spirits out of the home to fooling spiders and wasps into thinking that the ceilings are actually the sky. Many old houses around the Victorian and Colonial era bear this color in their porches due to the popularity at the time, but even now the popularity of the color is prevalent. Besides keeping evil spirits from entering the homes and fooling bugs, the blue ceiling reminds the owners of the blue skies even on cloudy days. Hypothesis The blue paint used in the painting of porches of the Victorian and Colonial homes contains an ingredient that repels insects, a natural insecticide used in the popular paint color. Prediction If there is an ingredient that naturally repels insects in the blue paint then the results should be obvious. Painting two porches ceilings one with blue paint and another one with white paint should demonstrate that the one with blue paint is bug free during the time of the experiment. Controlled Experimental Method First three enclosures were built; enclosure number one ceiling is painted sky blue. Enclosure...

Testing a Theory

...Testing A Theory PSY/201 May 12, 2013 A couple of years ago, I decided to test a theory on myself by trying to lose fight while gaining more muscle mass. I have heard so many different theories on how to lose fat while gaining muscle mass, but I could not find a good routine that gave me the best results. Before I began my research, I had to think critical about what was causing me to gain fat, and why my workout routine was not as effective on myself as it was for others. I began to search for credible sources on the Internet, so that I can have a better understanding of the relationship between nutrition and the human body. Once my understanding on nutrition was clear, I then began to do research on fat burning and strength conditioning. After my research was complete, I began to test these theories on myself. I created a chart that kept track of each exercise, the amount of repetitions completed, weight loss or gain, and body fat percentage. I used this chart to compare my before and after results within 90 days, and the end results were stunning. I could lower my body fat percentage, and gain more muscle mass, which was exactly what I wanted. The type of informal research that was used to test this theory was experimental research. According to the textbook, Psychology and Your Life, it tells us about experimental research, which states, “Investigator produces a change in one variable to observe the effects of that change on other variables” (Ch. 1, pg. 33)...

Scientific Method

...scientific method was trying to plant roses and trying to keep them alive. I would plant the roses and water them and even planted them in the sun. I would not try to figure out why they would keep dying. If I would have went through and tried fertilizer and tried to figure out why they kept dying then I would have at least came to a conclusion. If I would have found out how to take care of roses and then started to water them the way they are supposed to be watered and gave the roses the fuel they need to live they would not have died. I would have first seen how to take care of roses. Then I would have measured out the water and how much sun they needed and applied that then tested my theory I could have seen if they would have lived. If the roses had died after that then I would have tested other theories to see what works like trying to put fertilizer around the base of the rose bush to see if the ground was not the reason the roses were dying. If the ground does not have enough nutrients then the roses would not have been able to get the food it needed from the...

Biology Scientific Method

...Scientific Method Sharon Childers Unit 1 Individual Project May 5, 2013 Biology American Intercontinental University Biology is the study of life. When studying Biology one will study the way organisms live and their lives. How are humans created? How are cell formed? What is DNA made of? All of these questions are some form of Biology. Even the color of certain birds is a part of Biology. When dealing with the Sciences you will come across the Scientific Method. This method consists of: Question, Hypothesis, Research, Experiment, Analysis and Conclusion. Below we will discuss a question and complete the steps of the Scientific Method to come up with an answer to the question. Question Do ruby-throated hummingbirds prefer some colors more than others when visiting flowers? Hypothesis In my opinion I believe hummingbirds prefer bright colors opposed to darker colors. The hummingbird has a red throat so considering that I would think they prefer red or something similar to red when it comes to picking flowers to visit. Research Ruby-throated Hummingbirds are primarily in the United States. These small birds are hard to find in the sky because they are only 2-3 in and can flap their wings 53 times in one second. That’s kind of hard to believe or even imagine. When it comes to the type of feeder a hummingbird feeds on doesn’t really matter. They tend to eat from any kind of feeder. When it comes to flowers they prefer, red and yellow are their preference...

Atonement

...Fuller, Morris, Elwell, W H Kent, and Kohler. There were also many different views on the atonement expressed. One particular author who’s work that stuck out to me was L Morris. Within Morris’ writing it seamed that several views on the atonement were touched. The thing that struck me about all the different viewpoints is while some of the views could seem as if to build off of each other, other views contradicted each other. For instance the Moral Influence theory insists that man’s sin is taken away when he answers in love to Christ’s sacrifice. This Moral Influence theory shares some similarities with the Sacrifice theory, which states that Christ’s sacrifice is the important component in atonement. Another theory that Morris discusses, Atonement as Victory, takes the Sacrifice theory even further and states that God’s strength is the driving force behind the atonement. There were many more theories discussed my Morris and the other authors that can be discussed but it seems to me that none of theses ideas or theories seem to present a solid model that can be steadily applied to the teachings of Scripture. When it comes to Dr. Elmer Towns view of the...

Personality Paper

...personality, most definitions refer to a person’s mental system. This accumulation of psychological collections will include emotions, motives, and thoughts. ”Personality includes all those relatively permanent traits or characteristics that render some consistency to a person’s behavior” (Fiest & Fiest, 2009). Traits among individuals may be unique, mutual with few, or common among an entire species; however, the pattern will always be different for each and every person. People may share similar thoughts, views, etc; but they are still very much unique. The Scientific Approach to Studying Personality When examining theoretical approaches to the study of personality, “people confuse theory with philosophy, speculation, hypothesis, or taxonomy (Fiest & Fiest, 2009. Scientists use theories and detective reasoning to formulate hypothesis that...

Optionally, the author may raise objections to other views on the subject before presenting his or her own view. 2. Proposal of a theory (or principle) which can be used to analyze the case All case analyses must have some theoretical framework on which they are based. Without a framework that illustrates clear behavior-guiding principles, any case analysis will lack compelling support and risk incoherence. 3. Critical analysis of the theory and explanation of why it is superior to alternative theories or principles If the theory has unacceptable flaws, then any case analysis based on that theory or principle will inherit related flaws. Consequently, the author must defend the theory against opposing viewpoints by offering supporting arguments and responding to objections. Any mysterious or puzzling concepts must also be clarified. 4. Application of the theory to the case in question Once the theory or principle has been established and defended, the author analyzes the case using the theory and its core principles as a guide and explains the conclusions that are reached. 5. Critical analysis of the theory’s application to the case in question After analyzing the case using the theory, the author evaluates the...

Associationism Learning Theory

...Associationism Learning Theory Psychology is a very complex idea to study. With so many different theories written by many different theorists it is almost impossible to say when and how psychology was started. One of the earliest theories is the associationism learning theory which is known as the beginnings of a cognitive theory. Associationism is a theory that explains how items combine in the mind to produce thoughts and learning. Tracing all the way back to Aristotle, this learning theory is quite easy to understand and has a great history of great minds associated with it. The basis of associationism is quite easy to understand. Items are associated in the mind through a person’s experience. These items then form a thought. For example, we know not to touch a pan coming out of the oven because the pan will be hot, and we know that touching something hot will cause pain, therefore we do not touch the pan. Typically there are four principles of associationism which were assumed to hold true for 2000 years; the law of contiguity, the law of frequency, the law of similarity, and the law of contrast. The law of contiguity states that items that are contiguous in time or space are lined by associations (Lucas, 2002). In other words, things or events that occur close to one another tend to get linked together in the mind. If you see a coffee cup you may think of drinking coffee. Psychologists Edwin Ray Guthrie is remembered for his theory of learning based on association...
