BASED ACTUAL WITH QUESTIONS AND
ANSWERS
Which of the following is not an effect of angiotensin II? - ANS-✅Reduced aldosterone release
What is the role of erythropoietin released by the kidney? - ANS-✅It stimulates red blood cell
production
Aldosterone upon secretion by the adrenal cortex will have what effect on solute movement in the
kidneys? - ANS-✅K loss on the urine, Na retention in the plasma
Urodilantin is a naturietic peptide and as such has what effect on kidneys/nephrons? - ANS-✅It
enhances Na secretion and K retention
The pyramids contain the collecting ducts that drain through the papilla and are collected by the - ANS-
✅Calyx
The principal cells function to - ANS-✅Reabsorb Na and secrete K
The creatinine clearance rate is a measure that typically is used to evaluate - ANS-✅The GFR
Which of the following is a symptom of chronic renal failure - ANS-✅Hypocalcemia
The loss of albumin one the urine will produce all of the follow effects except - ANS-✅Reduction of
mesangial cells and increase in podocytes
Which of the following is an inhibitor of stone formation? - ANS-✅Uromodulin (Tamm Horsfall proteins)
The intercalated cells function to - ANS-✅Reabsorb K and secrete H
Antidiuretic hormone works by - ANS-✅Incorporating aquaporins into the distal tubule and collecting
ducts, making them permeable
Which is not associated with chronic kidney disease - ANS-✅Hypercalcemia
The most common organism causing uti is - ANS-✅E. Coli
Which of the following is the most common kidney stone - ANS-✅Calcium oxalate
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 plasma osmolarity. How do these
changes affect the secretion of ADH? - ANS-✅both the decrease in plasma volume and the increase in
osmolarity stimulate ADH secretion
The area where blood is filtered and proteins are generally separated from the plasma is - ANS-
✅Glomerulus
The modified smooth muscle cells that secrete renin are the - ANS-✅Juxtaglomerular cells
Vitamin D is essential for - ANS-✅The absorption of Ca and phosphate from the GI tract
Which of the following does not favor a large glomerular filtration rate - ANS-✅high resistance in the
afferent arteriole
Which signs and symptoms best fit nephritic syndrome - ANS-✅Hematuria with casts, HTN, and mild
proteinuria
Which of the following is a risk factor for post obstructive diuresis - ANS-✅Hypertension
The biggest stimulus (driver) of renin release is - ANS-✅Decreased Na concentration in distal tubules
The low hydrostatic pressure, high oncotic pressure that allow for reabsorbtion of valuable substances
from filtrate are the - ANS-✅Peritubular capillaries
Glucose reabsorption occurs in the _______. - ANS-✅proximal convoluted tubule
An increase in renal vein and thus capillary, hydrostatic pressure is most likely to have what effect of GFR
- ANS-✅Decreased GFR
Urine does not reflux back up into the ureter because - ANS-✅The lower end of the ureter compressed
by the detrusor muscle during micturition
