    Use of an artificial kidney during hemodialysis
    may result in :
    (a ) Nitrogenous waste build-up in the body
    (b) Non-elimination of excess potassium ions
    (c) Reduced absorption of calcium ions from
    gastro-intestinal tract
    (d) Reduced RBC production
    Which of the following options is the most
    appropriate?
    (1) (a) and (b) are correct
    (2) (b) and (c) are correct
    (3) (c) and (d) are correct
    (4) (a) and (d) are correct
    digAnsr:   3
    Ans : ( 3 )
    Sol. a and b statements are incorrect because
    dialysis eliminates urea and potassium from
    the body whereas, c and d are correct. As
    phosphate ions are eliminated during dialysis,
    along with that calcium ions are also
    eliminated. So, there will be reduced
    absorption of calcium ions from
    gastrointestinal tract. RBC production will be
    reduced, due to reduced erythropoietin
    hormone.
