In clinical settings, some of the most common questions that patients ask are Why do I have this? What caused this disorder? Will it ever go away? These emotional questions can be difficult to ask and to answer. However, for patients to come to terms with their diagnoses and adhere to treatment plans, they must have an understanding of factors that might have caused, or continue to impact, their disorders. As an advanced practice nurse, it is important that you are able to explain disorders, associated alterations and symptoms, and changes that might occur within your patients’ bodies.

NURS 6501 Week 1 Discussion

To prepare FOR NURS 6501 Week 1 Discussion:

Review this week’s media presentation with Dr. Terry Buttaro. Reflect on the importance of developing an in-depth understanding of pathophysiology.

Select a disorder from the following list:

Adrenal insufficiency (Addison’s disease)
Atherosclerosis
Cholelithiasis (gallstones)
Colon cancer
Cystic fibrosis
Hemophilia
Nephrolithiasis (kidney stones)
Osteoporosis
Parkinson’s disease
Tuberculosis

Select one of the following patient factors: genetics, gender, ethnicity, age, or behavior. Reflect on how that factor might impact your selected disorder, as well as potential associated alterations and symptoms.

Identify the pathophysiology of the associated alterations, including the normal and altered cellular function. Consider both intra- and extra-cellular changes that occur.

By Day 3 OF NURS 6501 Week 1 Discussion

Post a brief description of a patient scenario involving the disorder and the factor you selected. Explain how the factor might impact your selected disorder, as well as potential associated alterations and symptoms. Finally, explain the pathophysiology of the associated alterations, including changes in cellular function.
Read a selection of your colleagues’ responses.

By Day 6 OF NURS 6501 Week 1 Discussion

Respond to at least two of your colleagues on two different days who selected different disorders and factors than you, in the following ways:

Share insights on how the factor you selected impacts the pathophysiology of the disorder your colleague selected.
Expand on your colleague’s posting by providing additional insights or contrasting perspectives based on readings and evidence.

Walden NURS 6501 Week 1 Quiz

Question Question 1 How are potassium and sodium transported across plasma membranes? a. By passive electrolyte channels b. By coupled channels c. By adenosine triphosphate enzyme (ATPase) d. By diffusion Question 2 1 out of 1 points What causes the rapid change in the resting membrane potential that initiates an action potential? a. Potassium gates open, and potassium rushes into the cell, changing the membrane potential from negative to positive. b. Sodium gates open, and sodium rushes into the cell, changing the membrane potential from negative to positive. c. Sodium gates close, allowing potassium into the cell to change the membrane potential from positive to negative. d. Potassium gates close, allowing sodium into the cell to change the membrane potential from positive to negative. Question 3 1 out of 1 points A patient wants to know the risk factors for Down syndrome. What is the nurse’s best response? a. Fetal exposure to mutagens in the uterus b. Increased paternal age c. Family history of Down syndrome d. Pregnancy in women over age 35 Question 4 In teaching a patient with cirrhosis, which information should the nurse include regarding cholesterol? a. Cholesterol decreases the membrane fluidity of the erythrocyte, which reduces its ability to carry oxygen. b. Cholesterol decreases the membrane fluidity of erythrocytes, which reduces its ability to carry hemoglobin. c. Cholesterol increases the membrane fluidity of erythrocytes, which allows binding of excess glucose. d. Cholesterol increases the membrane fluidity of erythrocytes, which prolongs its life span beyond 120 days Question 5 1 out of 1 points During childhood, the thymus decreases in size, and this is referred to as _____ atrophy. a. Physiologic b. Pathologic c. Disuse d. Neurogenic Question 6 1 out of 1 points A nurse is reviewing the pedigree chart. When checking for a proband, what is the nurse looking for? a. The person who is first diagnosed with a genetic disease b. The individual who has a disease gene but is phenotypically normal c. The phenotype of genetic material d. The codominance Question 7 A cell is isolated, and electrophysiology studies reveal that the resting membrane potential is –70 millivolts. The predominant intracellular ion is Na , and the predominant extracellular ion is K . With voltage change, which of the following would result in an action potential? a. K rushing into the cell b. Na rushing into the cell c. Na rushing out of the cell d. K rushing out of the cell Question 8 1 out of 1 points A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would reveal which of the following? a. XY b. XX c. XYY d. XXY Question 9 1 out of 1 points When a patient asks what causes cystic fibrosis, how should the nurse respond? Cystic fibrosis is caused by an _____ gene. a. X-linked dominant b. X-linked recessive c. Autosomal dominant d. Autosomal recessive Question 10 1 out of 1 points A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? a. Electron-transport chain b. Aerobic glycolysis c. Anaerobic glycolysis d. Oxidative phosphorylation Question 11 1 out of 1 points Why is potassium able to diffuse easily in and out of cells? a. Because potassium has a greater concentration in the intracellular fluid (ICF) b. Because sodium has a greater concentration in the extracellular fluid (ECF) c. Because the resting plasma membrane is more permeable to potassium d. Because there is an excess of anions inside the cell Question 12 1 out of 1 points What is the role of cytokines in cell reproduction? a. Provide growth factor for tissue growth and development b. Block progress of cell reproduction through the cell cycle c. Restrain cell growth and development d. Provide nutrients for cell growth and development Question 13 0 out of 1 points A nurse is teaching a patient with diabetes how glucose is transported from the blood to the cell. What type of transport system should the nurse discuss with the patient? a. Active-mediated transport (active transport) b. Active diffusion c. Passive osmosis d. Passive-mediated transport (facilitated diffusion) Question 14 1 out of 1 points A 50-year-old male was recently diagnosed with Huntington disease. Transmission of this disease is associated with: a. Penetrance b. Recurrence risk c. Expressivity d. Delayed age of onset Question 15 1 out of 1 points The nurse is teaching staff about the most common cause of Down syndrome. What is the nurse describing? a. Paternal nondisjunction b. Maternal translocations c. Maternal nondisjunction d.
