¶ … interrelated -- not always completely worked out, but ways to guide research and experimental design. Within each theoretical framework we find cases that are objects in which we study behavior, characteristics, and attributes. Then, we must have dependent and independent variables. The dependent variable is the outcome -- or the variable one is trying to explain or predict; the independent variable is the explanatory factor(s) that explain variation -- the causes.
(a) The literature review is a procedure or body of text that reviews the current and past knowledge of a particular subject; typically designed so the researcher is certain to understand what the field has already said about the research question, what holes may be in the research, and what needs to be answered. One alternative to the literature review is a mixed method study (qualitative and quantitative) method called a meta-analysis...
This helps, too, with a systematic review of the information in the field on a particular method or subject.
(b) Using a literature review is advantageous because it asks the researcher to find and analyze groupings of thought on a particular subject. It allows a greater sense of expertise, and helps to formalize the research question by establishing parameters and reducing the idea of duplication from the research question; and also to enhance directionality of the research. Disadvantages to the process include needing to be at a particularly high level of skill to effectively analyze the sources and the limitation of most of the literature being older and potentially outdated material that may or may not be relevant to the new research question.

Hypertension among African-Americans Nursing Process and Health Promotion of Groups and Community Theory Hypertension is very rampant in African-Americans, and health providers link it with three major chronic diseases, which include; stroke, kidney and heart diseases. This paper examines the incidence of hypertension in African-Americans in the five subsystems of the SDS Assessment Categories. African-Americans suffer high risks of organ damage as well as stroke and heart diseases, caused by hypertension. Health
Hypertension, Hypercholesterolemia, Depression Hypertension, Hypercholesterolemia, and Depression: A Case Scenario Mr. P is a 65-year-old Hispanic male who presents to the clinic with a symptomatology that leads to three broad closely associated diagnoses: hypertension, hypercholesterolemia and depression. A review of the clinical presentation, history, physical examination and lab values indicate the following primary concerns: Total cholesterol of 280mg/dL, high-density lipoprotein (HDL) of 25mg/dL, low-density lipoprotein (LDL) of 189mg/dL, a blood pressure of
Hypertension One of the major health problems that the American society and the whole world experience is the prevalence of hypertension or high- blood pressure- caused illnesses or deaths in many people today. A special report made by the website Lifeclinic.com stated that almost 50 million Americans have hypertension, "1 in every 4 adults" (2002). This statistic illustrates the increasing number of people who are gradually suffering and eventually dying due
M., 2009, p. 1474). IMPACT on the FAMILY: Although hypertension is one of the most prevalent of all disorders in the United States, it does not affect nor impact the family of a person with this disorder as much as other diseases, such as heart disease, stroke, Alzheimer's and other disorders associated with the central nervous system. Overall, hypertension does affect a person's family in one important way, being the build-up of
Other factors include a history of alcohol and tobacco use, and dietary assessment including saturated fat and caffeine. Also certain prescribed and over-the-counter medications, herbal remedies, and illicit drugs may be factors, as well as psychosocial and environmental factors such as family situation, employment status, working conditions, and educational levels (Guidelines). Aside from routine physical examinations, laboratory tests, such as urinalysis, blood cell count and blood chemistry may be used
Hypertension In this text, I concern myself with hypertension. In so doing, I will amongst other things discuss its causes and possible complications. Further, I will also highlight treatment and control options with a particular emphasis on lifestyle changes, exercises, etc. Causes Hypertension could either be secondary or essential (Toth and Cannon, 2010). Unlike secondary hypertension, essential hypertension has no clear or exact cause. For this reason, this category of hypertension is often
