A 24-hour urine collection with a volume of 1550 mL has a sodium concentration of 97 mg/dl, what is the sodium excretion per 24 hours in units of mg/day?

Solution

Solution:

1 ml=0.01 dl

1550 mL volume of sodium =?

=15.5 dl of Sodium

Concentration in dl*volume in dl= weight of sodium excreted

Weight of sodium=97 * 15.5

=1503.5 mg /day
