Show Answers:

  1. The loss of cholride, potassium, and fluid volume may cause?
    Metabolic Alkalosis
  2. Its this organ's job to reabsorb sodium because sodium has a major role in maintaing fluid balance.
    The kidneys.
  3. is a mothod in which sodium is reasbsorbed out from the renal tubule cell into the blood.
    Primary Active Transport
  4. Done by the kidney, allows for exchange of Na+(reabsorption of Na+)
    Secondary active secretions of H+ and K+
  5. Compensaory responce is hypoventilation (CO2 retained) when this is happening.
    Metabolic Alkalosis
  6. The correction of this disorder is restoring normal fluid volume and electolyte % (esp. K+ and Cl- levels). Treat w/KCL(hypokalemia), dilute HCl- or NH4Cl- in sever cases
    Metabolic Alkalosis
  7. is defined as the plasma concentration of HCO3 in mEq/L that would exist ( at body temperature) with a normal PCO2 od 40mmHg.
    Standard Bicarbonate
  8. Standard Bicarbonate eliminates the effect of dissolved ____________ levels (hydration RXN) thereby allows one to assess strictly the metabolis component of acid-base balance.
    CO2 on HCO3-
  9. indicator of metabolic acid-base disturbances. Helps fine tune analysis when compensation or mixed disorders occur. done by equilibrating blood sample in the las to a PCO2 of 40mmHg at BT 37 degrees
    Base Excess ( Base Deficit)
  10. Positive BE > +2 indicates?
    gain of base or loss of acid
  11. Negative BE < -2 indicates?
    a loos of base or gain of acid
  12. A change in BE/BD shows __________, it could be primary or it could be compensation.
    metabolic involvement
  13. In acute respiratory acidosis, the BE/BD would be ________. This idicates that the pH change is purely respiratory.
  14. In compensated respiratory acidosis, the BE will ________.
  15. This is determined by multiplying the extracellular fluid volume by the base deficit in mEq/L from ABG
    Total Body deficit
  16. To estimate an individual's extracellular fluid volume in leters you need to?
    Take 1/4 of the body weight in kg.
  17. Normally NaHCO3- is administered only in the case of severe__________.
    Metabolic acidosis.
  18. This is defined as a base deficit of a 10mEq/L and one of the follow inf exist: a pH <7.20 or a pH between 7.20 and 7.25 with an unstable cardiovascular system.
    Severe metabolic acidosis
  19. if the base deficit is 10mEq/L and the pH is > 7.25 do you give NaHCO3-?
    Not normally
  20. This is due to a change in both metabolic and respiratory parameters changing in opposite directions.
    Mixed acid-Base (ex. Acidosis: CO2 increases HCO3 decreases)
  21. both resp. and meta. exist. both promoting the same acid-base disturbance.
    Combined disturbance.
