1. The sodium (Na+) sensing cells in the distal tubules are the: - correct answer ✔✔macula
densa
2. Vitamin D is essential for: - correct answer ✔✔The absorption of Ca++ and phosphate from
the GI tract
3. The renal blood flow, and thus GFR, are kept relatively constant by____. - correct answer
✔✔Myogenic (Intrinsic) autoregulation
4. The biggest stimulus (driver) of renin release is: - correct answer ✔✔Decreased Na+
concentration in the distal tubules
5. The most common organism causing urinary tract infection is: - correct answer ✔✔E. coli
6. Acute cystitis is best described as: - correct 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 the following? - correct
answer ✔✔Increased water excretion in the urine
8. A patient presents with flank pain and anuria followed by polyuria after
undergoingcatheterization of the ureters. What is the most likely cause of this condition? -
correct answer ✔✔Postrenal acute renal failure
, 9. The modified smooth muscle that secrete renin are the - correct answer ✔✔Juxtaglomerular
cells
10. Antidiuretic hormone works by - correct answer ✔✔Incorporating aquaporins into the distal
tubule and collecting ducts, making thempermeable to water
11. Enlargement of the renal pelvis and calyces due to upper urinary obstruction would bestbe
termed a(n)? - correct answer ✔✔Hydronephrosis
12. Which of the following is a symptom of chronic kidney disease - correct answer
✔✔Hypocalcemia
13. Which of the following would be expected to trigger a decrease in the secretion of ADH? -
correct answer ✔✔ingestion of a large amount of pure water
14. What is the role of erythropoietin released by the kidney? - correct 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: - correct answer ✔✔Calyx (calyses)
16. Because sweat is essentially a salt solution with an osmolarity lower than that of
plasma,severe sweating leads to a reduction in plasma volume and an increase in
plasmaosmolarity. How do these changes affect the secretion of ADH? - correct answer
✔✔Both the decrease in plasma volume and the increase in plasma osmolarity stimulate ADH
secretion
17. Glucose reabsorption occurs primarily in the - correct answer ✔✔Proximal convoluted
tubule
