    About the Lecture

    The lecture Regulation of ADH: Significance of Clearance of Water by Carlo Raj, MD is from the course SIADH.


    Included Quiz Questions

    1. 275 mOsm/L
    2. 250 mOsm/L
    3. 290 mOsm/L
    4. 320 mOsm/L
    5. 300 mOsm/L
    1. All are correct
    2. A given plasma osmolality will result in a higher ADH concentration
    3. Plasma ADH concentration will increase
    4. Plasma Angiotensin II concentration will increase
    5. The range of osmolalities that will activate hypothalamic osmoreceptors will decrease
    1. Increased ADH activity
    2. Loop diuretics
    3. Urine is isotonic to plasma
    4. Clearance of free water is zero
    5. All are associated with isosthenuria
    1. Free water must be generated in the thick ascending limb
    2. Urine must be hypertonic compared to plasma
    3. Sodium reabsorption must be impaired
    4. The countercurrent multiplier must be impaired
    5. Diluting ability of the kidney must be impaired
    1. It represents positive free water clearance
    2. It may be induced by elevated plasma ADH concentration
    3. It may be induced by severe hypovolemia
    4. Concentration of the urine relies on the countercurrent multiplier
    5. It may be induced by water deprivation
