Questions and Answers
  • 1. 
    Both thiazide and loop diuretics mechanism of action are based upon inhibiting the reabsorption of Na+ and Cl- ions.
    • A. 

      True

    • B. 

      False

  • 2. 
    Osmotic diuretics work by _________ osmolarity, preventing water reabsorption, causing a loss of water, Na+, Cl-, and HCO3.
    • A. 

      Increasing

    • B. 

      Decreasing

  • 3. 
    K+ sparing diuretics inhibit Na+, Cl-, and HCO3 reabsorption and K+ secretion in the distal convoluted tubules.
    • A. 

      True

    • B. 

      False

  • 4. 
    _________ antagonists bind to cytoplasmic mineralocorticoid receptors on collecting ducts, inhibiting the reabsorption of Na+ and Cl-, preventing the secretion of K+.
  • 5. 
    Carbonic anhydrase inhibitors bind to carbonic anhydrase in the proximal tubules, retaining H+ ions while excreting HCO3+ ions.  K+ is also excreted in exchange for Na+.  HCO3 excretion causes alkaline urine, the body enters a metabolic acidosis.
    • A. 

      True

    • B. 

      False

  • 6. 
    Renal dopamine-1 receptors mediate vasodilation, _________ RBF and GFR while inhibiting Na+ reabsorption.
    • A. 

      Increasing

    • B. 

      Decreasing
