The Nurse Caring for an Older Adult Client Diagnosed with Both

The nurse caring for an older adult client diagnosed with both chronic cardiac and renal disorders best minimizes the client's risk of developing dehydration as a result of being hypovolemic by:

A) identifying the client's oral fluid preferences and offering them to him regularly.
B) carefully monitoring the effects of daily diuretic therapy via blood sodium levels.
C) minimizing the client's reliance on laxatives by increasing his dietary fiber intake.
D) careful monitoring of the rate of infusion of all intravenous fluids prescribed.
