BIO 669 RENAL
1. The distal tubule sodium (Na+) sensing cells are the: - ANSWER>>macula densa
2. Vitamin D is necessary for: - ANSWER>>The absorption of Ca++ and phosphate from
the GI tract
3. Renal blood flow, and hence GFR, remains relatively constant due to____. -
ANSWER>>Myogenic (Intrinsic) autoregulation
4. The most potent stimulus (driver) for renin release is: - ANSWER>>Decreased Na+
concentration in the distal tubules
5. Most common organism causing urinary tract infection is: - ANSWER>>E. coli
6. Acute cystitis is best described as: - ANSWER>>Inflammation of the bladder
presenting with frequency, dysuria and lower abdominaland/or suprapubic, low back
pain
,7. An increase in mean arterial pressure MAP stimulates which of following? -
ANSWER>>Increased water excretion in the urine
8. A patient has flank pain and anuria followed by polyuria after
undergoingcatheterization of the ureters. What is the most likely cause of this
condition? - ANSWER>>Postrenal acute renal failure
9. The modified smooth muscle that secrete renin are the - ANSWER>>Juxtaglomerular
cells
10. Antidiuretic hormone works by - ANSWER>>Incorporating aquaporins into the
distal tubule and collecting ducts, making thempermeable to water
11. Dilatation of the renal pelvis and calyces due to obstruction of the upper urinary
tract would most appropriately be termed a? - ANS>>Hydronephrosis
12. The following is a symptom of chronic kidney disease - ANS>>Hypocalcemia
13. Which of the following would tend to decrease the secretion of ADH? -
ANS>>ingestion of a large volume of pure water
14. What is the role of erythropoietin released by the kidney? - ANSWER>>It stimulates
red blood cell production in the bone marrow
15. The pyramids contain the collecting ducts that drain through the papilla and are
collected by the: - ANSWER>>Calyx (calyses)
16. Because sweat is essentially a salt solution whose osmolarity is less than that of
plasma, profuse sweating decreases plasma volume and increases plasma osmolarity.
What effect do these changes have on the secretion of ADH? - ANSWER>>Both the
decrease in plasma volume and the increase in plasma osmolarity stimulate ADH
,secretion
17. Glucose reabsorption takes place primarily in the - ANSWER>>Proximal convoluted
tubule
18. Aldosterone, when released from the adrenal cortex, will stimulate what type of
solute movement in the kidneys? - ANSWER>>K+ loss to the urine, Na+ retention in the
plasma
19. Each of the following is a risk factor for postobstructive diuresis EXCEPT -
ANSWER>>hypertension
20. Each of the following is a constant finding in nephrotic syndrome EXCEPT -
ANSWER>>Hypertension and vasoconstriction
21. Which one of the following inhibits the formation of stones? -
ANSWER>>Uromodulin (Tamm Horsfall proteins)
22. Which vessels have low hydrostatic pressure, high oncotic (osmotic) pressure,
allowing for the reabsorption of valuable substances from the filtrate? -
ANSWER>>Peritubular capillaries
23. Which of the following is not a condition to favor a large glomerular filtration rate? -
ANSWER>>High resistance in afferent arterioles
24. The creatinine clearance test is a measure that usually is used to estimate: -
ANSWER>>The GFR-glomerular filtration rate
25. Which of the following does NOT occur as a result of angiotensin II? -
ANSWER>>Decreased aldosterone release
, 26. Urine does not reflux (back up) into the ureter because: - ANSWER>>the lower end
of the ureter is compressed by the detrusor muscle during micturition
27. The outer capillary epithelium is composed of _____which fit with others to
formfiltration slits. - ANSWER>>Podocytes
28. The intercalated cells function to: - ANSWER>>Reabsorb K+ and secrete H+
29. The normal fasting glucose concentration is 100 mg/dL, and the renal threshold is
300mg/dl. If the plasma concentration doubles to 200 mg/dl, then: - ANSWER>>The
rate at which glucose is reabsorbed will double
40. Which of the following statements is CORRECT? - ANSWER>>Hypertrophy of the
opposite kidney compensates for loss of function of the kidney with obstructive disease.
41. __________, secreted from the adrenal gland, facilitates tubular reabsorption of fluid
bycontrolling sodium retention and the excretion of potassium via epithelial cells in
therenal tubules. - ANSWER>>Aldosterone
42. Hallmark signs of nephritic syndrome include all of the following
except_____________. - ANSWER>>Hypotension
43. The ___________ is sensitive to changes in __________ - ANSWER>>Juxtaglomerular
cell, pressure
44. Which of the following nephron function is/are performed by both the Loop of Henle
and the distal tubule? - ANSWER>>Both C & D
45. The nephrons best able to concentrate the urine are the ________ nephrons. -
ANSWER>>Juxtamedullary
