The kidneys are highly vascular organs that filter the blood, removing wastes for excretion and returning the rest of the blood to the vascular system. The functional units of the kidneys are nephrons, each composed of a glomerulus and a tubule. How is the GFR measured? What are the strengths and limitations of methods of determining GFR? Often … Read more
Emphysema, a hallmark of chronic obstructive pulmonary disease, is primarily caused by prolonged exposure to cigarette smoke, which leads to irreversible alveolar damage. Smoking initiates an inflammatory response characterized by increased neutrophils and macrophages, which release proteolytic enzymes such as elastase and matrix metalloproteinases (Barnes et al., 2020). These enzymes degrade elastin, an essential component … Read more
Case 1: Cardiovascular disease is the most common cause of adult morbidity and mortality, accounting for 31% of deaths worldwide. The most common vascular system disorder is hypertension, defined by the American College of Cardiology and the American Heart Association (AHA) as blood pressure >130/80 mm Hg. A) How do antihypertensive medications interact with determinants of … Read more
Self-Reliance and Cultural Competence From the chapter, the selected research study is the theory of self-reliance. The theory was developed by John Lowe and established within the Cherokee cultural values. Specifically, Lowe used the theory to create an understanding of the healthcare system within the Native Indian Americans (Im & Lee, 2023). The theory was first discussed in the original … Read more

It emphasizes the importance of being “true to self” by fostering responsibility, discipline, and confidence while maintaining a strong connection to one’s … Read more
Select a research study identified in chapter 13 and go to the literature to find its original source. Describe: a) how the theory of self-reliance is presented in the manuscript, b) what concepts are being studied and c) how the findings guide practice.
Write about a nursing theory. Introduction (Brief background of the theorist) Basic Concept Analysis (Briefly discuss the theory’s core concepts) Relevance (Discuss how the theorist connects to the theory, connect the theory to healthcare, connect the theory to current research/practice today) Use at least two peer-reviewed/research articles that detail the nursing theory being applied in clinical practice/research … Read more
Compare properties of the anterior pituitary hormones with the posterior pituitary hormones. How are they similar or different relative to regulation and mechanism of secretion, vulnerability to brain trauma and inflammation, and long-term consequences of dysfunction?
A tumor is an abnormal growth that be benign or malignant and can harm or even kill the host if proper interventions do not occur on a timely manner. A tumor is made up of tissue which serves no purpose to the host other than introducing a pathogen to the immune system. Benign tumors are … Read more
What is the “big picture” of the immune system’s role in maintaining homeostasis? The immune system is fundamental to the maintenance of homeostasis, as it ensures the internal stability of the organism in response to external threats and environmental fluctuations. This system functions as a sophisticated defense apparatus that identifies foreign entities, such as pathogens … Read more
