o some people that may have bladder control problems may be purposely dehydrated and drink less
water but we are hoping that they can clear waste product because if not the body will pull from its
other sources to excrete and cause consequential dehydration.
• How much waste product is a normal healthy adult able to excrete per liter? - Ans:✔✔-o Kidneys of
normal healthy adults can concentrate 1200 to 1400 milliosmole per liter (obligatory).
o If the renal solute load is 600 milliosmole:
600 milliosmole divided by 1200 milliosmole per liter = .5 liters
600 milliosmole divided by 1400 milliosmole per liter = .428 liters
So, 430 to 500 milliliters is the minimal amount of fluid needed to accommodate a renal solute load of
600 milliosmole.
