The nurse has identified the diagnosis Excess Fluid Volume as appropriate for a client with acute glomerulonephritis. What should the nurse assess to learn the most accurate indication of this client's fluid balance?
A) Vital signs
B) Intake and output records
C) Daily weight
D) Serum sodium levels
Answer: C
Daily weight provides the most accurate indication of fluid balance because of the pathophysiology of acute glomerulonephritis. Albumin is lost, causing decreased osmotic pressure and fluid shifting into the interstitial spaces. Accurate weights will provide data to indicate that treatments are effective in pulling fluids from interstitial spaces into the vascular system and then out via kidneys. Intake and output records, serum sodium levels, and vital signs will all provide data indicating fluid balance; however, they are not as accurate as daily weight for determining fluid balance.
