  1. Body weight normal is ____ Body weight current before patient was volume depleted
  2. what are potential causes of Euvolemic Hypotonic Hyponatremia?
  3. what is normal solute concentration?
  4. IVNa = sodium concentration of infusate 3% is how much mEq?
  5. IVNa = sodium concentration of infusate 0.9% is how much mEq?
  1. a 15%
  2. b 513mEq
  3. c 154mEq
  4. d -SIADH (UOsm > 100 mOsm/kg) = [ADH] is high, and hang on to water and this dilutes Na+
    -Diseases: Tumors, CNS disorders, pulmonary disease
    Medications: desmopressin = vasopressin analog, carbamazepine, cyclophosphamide, SSRI's, TCA's, NSAIDs, "ecstasy"
  5. e - (275 - 290 mOsm/kg)

5 Multiple choice questions

  1. -ADH is suppressed: UOsm < 100 mOsm/kg VERY DILUTE URINE
    -Euvolemic Hypotonic Hyponatremia
  2. -Ability of combined effect of all solutes to generate osmotic driving force that causes H2O movement from one compartment to another (if osmolality is high in EC-compartment, compared to what's inside cells, will be hypertonic)
  3. -↓ serum Na+ concentration, ↑ measured ECF osmolality & tonicity
    -Severe hyperglycemia in uncontrolled diabetes mellitus
  4. -Restriction of water < 1 - 1.2 L/day
    -Restrict Na+ < 1 - 2 g/day
    -Improve circulating blood volume: to ↓ ADH release
  5. -there are substances in the blood that aren't being measured, there are exogenous compounds that aren't in the equation (Mannitol=hyperosmolol diuretic, sorbitol=induce diarrhea, ethanol, methanol=blindness cheap alcohol, ethylene glycol=antifreeze poisoning)

5 True/False questions

  1. Extracellular fluid volume (ECFV= outside cells) ?2/3 TBW


  2. Treatment of Diabetes Insipidus, Nephrogenic DI is done by giving what?-Correct hypercalcemia and hypokalemia
    -Create mild ECFVd with thiazide diuretic and dietary Na+ restriction ↓ urine volume
    -Indomethacin 50 mg po tid (increase sensitivity to ADH)
    -Amiloride 5 - 10 mg po daily (lithium induced DI, antagonizes Li effects on kidney tubules)


  3. Hypertonic, can be defined as?-more solutes inside cells and less outside-more water outside and cell lysis-cerebral edema


  4. Syndrome of inappropriate ADH release (SIADH) can be defined as?-↓ serum Na+ concentration, ↑ measured ECF osmolality & tonicity
    -Severe hyperglycemia in uncontrolled diabetes mellitus


  5. a Crystalloids can be defined as?-Packed red blood cells, albumin 5%, albumin 25%, dextrans and hetastarch
    -Saved for certain things, typical hydration correction is done before colloids are initiated, more expensive only used with a compelling indication
