  7. Urodilantin is a natriuretic peptide and as such has what effect on the kidneys/nephrons? - Correct Ans : It enhances Na+ secretion and K+ retention
  1. Aldosterone, upon secretion by the adrenal cortex, will have what effect on solute movement in the kidneys? - Correct Ans : K+ loss in the urine, Na+ retention in the plasma
  2. What is the role of erythropoietin released by the kidney? - Correct Ans : It stimulates red blood cell production in the bone marrow
  3. The renal blood flow and this GFR are kept relatively consistent by: - Correct Ans : Myogenic (intrinsic) autoregulation
  4. Which of the following is NOT a consistent finding in nephrotic syndrome? - Correct Ans : Hypertension and vasoconstriction
  5. Which of the following does not stimulate aldosterone release?
    • Correct Ans : Arterial natriuretic peptide
  6. Assume that fluid enters the distal tubule with an osmolarity of 100 mOsm, and that the maximum osmolarity of medullary interstitial fluid is 1100 mOsm. As plasma ADH levels rise, the osmolarity of the urine: - Correct Ans : Approaches 1100 mOsm as an upper limit
  7. The outer capillary epithelium is composed of __________ which fit with others to form filtration slits. - Correct Ans : Podocytes
  1. The osmolarity of tubular fluid increases as it flows through the descending loop of Henle because: - Correct Ans : Water moves passively out of the descending limb
  2. A patient presents with flank pain an anuria followed by poly iris after undergoing catheterization of the ureters. What is most likely the cause of this condition? - Correct Ans : Post renal acute failure
  3. Which of the following would be expected to trigger a decrease in the secretion of ADH? - Correct Ans : Ingestion of a large amount of pure water
  4. Enlargement of the renal pelvis and calyces due to an upper urinary tract obstruction would best be termed a(n): - Correct Ans : Hydronephrosis
  5. The nephrons best able to concentrate urine are the __________ nephrons. - Correct Ans : Juxtamedullary
  6. Urine does not reflux (flow back up ) into the ureter because: - Correct Ans : The lower end of the ureter compressed by the detrusor muscle during micturition
  7. An increase in renal vein and thus capillary, hydrostatic pressure is most likely to have what effect on GFR? - Correct Ans : Decreased GFR
  1. Glucose reabsorption occurs primarily in the: - Correct Ans : Proximal convoluted tubule
  2. The low hydrostatic pressure, high oncotic (osmotic) pressure that allow for reabsorption of valuable substances form the filtrate are the: - Correct Ans : Peritubular capillaries
  3. The biggest stimulus (driver) of renin release is: - Correct Ans : Decreased Na+ concentration in the distal tubules
  4. Which of the following is a risk factor for post obstructive diuresis? - Correct Ans : Hypertension
  5. Which signs and symptoms best fit nephrotic syndrome? - Correct Ans : Hematuria with casts, HTN, and mild proteinuria
  6. Which of the following does not favor a large glomerular filtration rate? - Correct Ans : High resistance in the afferent arterioles
  7. Vitamin D is essential for: - Correct Ans : The absorption of Ca++ and phosphate from the GI tract
  8. The modified smooth muscle cells that secrete renin are the: - Correct Ans : Juxtaglomerular cells
  1. Which of the following is NOT an effect of angiotensin II? - Correct Ans :
