A 70-kg (154-lb) man on a fixed NaCl intake
(200 mmol/day) is given daily injections of a
potent mineralocorticoid hormone for 4 days. He
has free access to water and consumes his usual
caloric intake. Excretion of NaCl is as follows:
Day NaCl (mmol)
1 30
2 90
3 180
4 200
Assuming that 1 L of 0.9% saline contains 150
mmol of NaCl and weighs 1 kg, how much will
this patient weigh (in kg) at the end of day 4?
