Q

fluid rebound

A

occurs with patients on diuretics do not take in adequate water (decrease fluid intake to decrease trips to the bathroom)
results in concentrated plasma of smaller volume
decreases volume is sensed by nephrons, which activates RAAs cycle
concentrated blood is sensed by osmotic center in brain, ADH is released to hold water and dilute the blood
results in rebound edema as fluid is retained

weigh daily on same scale, clothes, and time of day, monitor BP, take potassium supplements or avoid potassium as ordered, maintain fluid intake to prevent fluid rebound or dehydration, teach s/s of fluid loss and aggravating factors (d/v/excessive heat and sweating), take diuretics in AM, change positions slowly, AE and when to notify PCP
