    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.

About This Quiz

The Otterbein\/Grant CRNA Diuretics Review quiz focuses on the mechanisms and effects of various diuretics. It assesses understanding of their action on different parts of the renal tubule, the impact on electrolyte balance, and the specific uses in clinical practice, essential for anesthesia-related pharmacology.

  • 2. 

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

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Thiazide and loop diuretics are both types of diuretic medications that work by inhibiting the reabsorption of sodium (Na+) and chloride (Cl-) ions in the kidneys. This leads to increased excretion of these ions in the urine, which in turn promotes water excretion and reduces fluid volume in the body. Therefore, the statement that both thiazide and loop diuretics mechanism of action are based upon inhibiting the reabsorption of Na+ and Cl- ions is true.

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

    • Increasing

    • Decreasing

    Correct Answer
    A. Increasing
    Explanation
    Osmotic diuretics work by increasing osmolarity. This means that they increase the concentration of solutes in the filtrate, which prevents water reabsorption in the kidneys. As a result, more water remains in the urine, leading to increased urine output. Additionally, the increased osmolarity also prevents the reabsorption of sodium (Na+), chloride (Cl-), and bicarbonate (HCO3-) ions, further contributing to the loss of water and electrolytes.

    Rate this question:

  • 4. 

    _________ antagonists bind to cytoplasmic mineralocorticoid receptors on collecting ducts, inhibiting the reabsorption of Na+ and Cl-, preventing the secretion of K+.

    Correct Answer
    Aldosterone
    Explanation
    Aldosterone antagonists are drugs that bind to cytoplasmic mineralocorticoid receptors on collecting ducts. By doing so, they inhibit the reabsorption of Na+ and Cl-, which leads to increased excretion of these ions. Additionally, they prevent the secretion of K+, further contributing to increased excretion of this ion. This mechanism of action helps to reduce fluid retention and lower blood pressure. Therefore, the given correct answer, Aldosterone, is the hormone that these antagonists target to produce their effects.

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

    • Increasing

    • Decreasing

    Correct Answer
    A. Increasing
    Explanation
    Work at dopamine receptors throughout renal tubules

    Rate this question:

  • 6. 

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

    • True

    • False

    Correct Answer
    A. True
    Explanation
    K+ sparing diuretics are a type of medication that work by inhibiting the reabsorption of sodium (Na+), chloride (Cl-), and bicarbonate (HCO3) in the distal convoluted tubules of the kidneys. By doing so, these diuretics prevent the excretion of potassium (K+), hence the term "K+ sparing." Therefore, the statement that K+ sparing diuretics inhibit Na+, Cl-, and HCO3 reabsorption and K+ secretion in the distal convoluted tubules is true.
