- #163Use 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 correctdigAnsr: 3Ans : ( 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.
