5 Matching questions

  1. when treating Non-Emergent Hypovolemic Hypotonic Hyponatremia what is done?
  2. Isovolemic Hypernatremia can cause Diabetes Insipidus Nephrogenic (make ADH but kidneys arent responding to it), how?
  3. Intracellular fluid volume (ICFV = inside cells)?
  4. Serum sodium concentration [Na+] is indicative of the amount of water relative to sodium. T/F?
  5. Syndrome of inappropriate ADH release (SIADH) can be defined as?
  1. a -Lithium toxicity
    -Hypercalcemia (reduce response to ADH and K+)
    -Hypokalemia
    -Demeclocycline (antagonizes ADH receptor, and can induce Isovolemic Hypernatremia, when trying to treat SIADH
  2. b -Nonosmotic ADH release leading to water retention & hyponatremia (go down because hanging on to more water diluting [Na+]
    -Hanging on to more water than Na+, serum Na goes down!
  3. c 2/3 TBW
  4. d -true, Total amount of sodium in ECF is major determinant of size of ECFV
    -Amount of Na+ in ECF (& ECFV size) determined by balance between Na+ intake and Na+ excretion by kidneys
  5. e -Administer 0.9% NaCl at 200 - 400 ml/h until symptoms of hypovolemia improve, then lower to 100 - 150 ml/h (calculate volume deficit)
    -No greater than 12 mEq/L/day increase in serum Na+
    -Monitor serum Na+ q2-4h, signs of hypovolemia, volume overload

5 Multiple choice questions

  1. -Absence or deficiency of ADH leading to excessive renal water loss and hypernatremia, urinate a lot = causing high [Na] hypernatremia
    -TCA-antidepressants = cause SIADH commonly
  2. -solutes outside-more water inside cells and cells shrink-brain can shrink and cause damage
  3. -Restriction of water < 1 - 1.2 L/day
    -Restrict Na+ < 1 - 2 g/day
    -Improve circulating blood volume: to ↓ ADH release
  4. -2 x [Na+ concentration] + [glucose concentration]/18 + [Blood Urea Nitrogen]/2.8 = solutes used to calculate serum osmolality
  5. -Indicated for hypervolemic or euvolemic hyponatremia
    -Conivaptan (Vaprisol®): Non-selective V1A and V2 receptor antagonist; IV only
    -Tolvaptan (Samsca®): Selective V2 receptor antagonist; oral only also approved in patients with SIADH (but not first line option)

5 True/False questions

  1. Nephrogenic diabetes insipidus (have ADH, but no kidney response) can be caused by?-Absence or deficiency of ADH leading to excessive renal water loss and hypernatremia, urinate a lot = causing high [Na] hypernatremia
    -TCA-antidepressants = cause SIADH commonly

          

  2. total ECF sodium, are related to what abnormality?-Cases of abnormal ECFV size (hypervolemia vs. hypovolemia) are due to problems with the sodium control mechanism

          

  3. Hypertonic Hyponatremia, can be defined as?-solutes outside-more water inside cells and cells shrink-brain can shrink and cause damage

          

  4. Primary or psychogenic polydipsia (drinking a lot of water= psychological condition); Intake of more water than kidneys can excrete (> 20L/day) what does this cause?-ECF sodium concentration (hypernatremia vs. hyponatremia) are due to problems with water control mechanisms

          

  5. IVNa = sodium concentration of infusate 3% is how much mEq?154mEq
