Identify the characteristic that DOES NOT describe the glomerulus. Select one: a. Fenestrated capillary endothelium b. Incomplete basement membrane c. Positively charged basement membrane d. Podocytes and slit pores in the tubule epithelial cells Feedback The correct answer is: Positively charged basement membrane. Q 3 Question 3 Patients with renal failure may Select one: a. suffer from anemia because they are unable to produce sufficient levels of renin. b. require calcium supplementation because the kidneys normally activate vitamin D, which is required for the absorption of calcium from dietary sources. c. experience both a decrease in hydrostatic pressure as well as an increase in osmotic pressure, which would account for the edema they experience. d. have an increased GFR that would account for the elevated creatinine and blood urea nitrogen (BUN) levels. Feedback The correct answer is: require calcium supplementation because the kidneys normally activate vitamin D, which is required for the absorption of calcium from dietary sources.. Q 4 Question 4 A patient with renal failure is likely to also have hyperalbuminemia. Select one: a. True b. False Feedback The correct answer is: False. Q 5 Question 5 The following three questions pertain to Case Study 8.B: Diabetes Insipidus. Diabetes insipidus Select one: a. is due to a lack of insulin secretion by the pancreas. b. may be caused by a lack of Anti-Diuretic Hormone (ADH, or vasopressin) secretion from the anterior pituitary. c. may be caused by a decreased ability of the kidney to respond to available ADH. d. is characterized by an elevated fasting blood glucose level. Feedback The correct answer is: may be caused by a decreased ability of the kidney to respond to available ADH.. Q 6 Question 6 Which of the following statements is about diabetes insipidus is CORRECT? Select one: a. Central diabetes insipidus may be treated by dDAVP, which is a synthetic replacement for vasopressin (or ADH). b. Nephrogenic diabetes insipidus may be treated with dDAVP, which is a synthetic replacement for vasopressin (or ADH). c. A person with central diabetes insipidus would have a normal level of ADH. d. Central diabetes insipidus is most often caused by chronic lithium ingestion. Feedback The correct answer is: Central diabetes insipidus may be treated by dDAVP, which is a synthetic replacement for vasopressin (or ADH).. Q 7 Question 7 Excessive urination associated with diabetes insipidus can cause dehydration and potassium losses. Select one: a. True b. False Feedback The correct answer is: True. Q 8 Question 8 The following three questions pertain to Case Study 8.C: Glomerulonephritis.

Alkalosis Feedback The correct answer is: Hyperkalemia. Q 13 Question 13 Blood transfusion reaction can cause acute tubular necrosis (ATN). Select one: a. True b. False Feedback The correct answer is: True. Q 14 Question 14 Which of the following statements about nephritic and/or nephrotic syndromes is correct? Select one: a. In nephrotic syndrome there is significant basement membrane damage that allows massive protein losses into the urine. b. In nephrotic syndrome there is massive red blood cell loss without significant protein loss into the urine. c. Nephrotic syndrome, but not nephritic syndrome, is characterized by hematuria. d. Nephrotic syndrome, but not nephritic syndrome, is characterized by fluid retention and edema. Feedback The correct answer is: In nephrotic syndrome there is significant basement membrane damage that allows massive protein losses into the urine..
