1. What is the difference between qualitative and quantitative research sampling strategies? Compare and contrast the strategies and describe some of the advantages and disadvantages of each.
2. 2. An inappropriate sample size can call into question an entire research project. How can a researcher determine what is an appropriate sample size? Share your research question for your research proposal assignment. What is an appropriate sample size for your proposal? Why?
3. 3. ESRD (end-stage renal disease) is the last stop in pathology for the kidney, and it is not a place we want a patient to be. However, there are many ways to intervene before a patient gets to this stage. Please visit the National Kidney Foundation website (www.kidney.org) and pick one best practice you can share with your patients to promote kidney health. Please share that practice with the class, and why you chose it.
4. 4. JH is a 12-year-old boy diagnosed several months ago with nephrosis following postinfectious glomerulonephritis secondary to an episode of pneumococcal pneumonia. He has been coming to the clinic to have his condition monitored and therapies adjusted as needed. At his latest clinic visit, a decrease in urine output, increasing lethargy, hyperventilation, and generalized edema are noted. Trace amounts of protein are detected in JH’s urine by dipstick. Blood is drawn for laboratory analysis, and the results are as follows: pH = 7.36 PaCO2 = 33 mm Hg PaO2 = 100 mm Hg HCO3 – = 18 mEq/L Hct = 30% Na+ = 130 mEq/L K+ = 5.4 mEq/L BUN = 58 mg/dl creatinine = 3.9 mg/dl albumin = 2.0 g/dl
A. A. How would a pneumococcal infection lead to glomerulonephritis? How can glomerulonephritis result in nephrosis?
B. B.Use JH’s laboratory values to determine if he is still experiencing nephrosis or if his condition is progressing to renal failure.
C. C. What additional physical or laboratory findings would be helpful in determining JH’s degree of renal impairment?
D. D. How will JH’s therapy change if his condition has progressed from nephrosis to uremia?
