Which of the following is used to monitor fluid balance in patients with fluid volume excess?

• A. Measure I & O's
• B. Increase protein intake
• C. Sleep more
• D. Take vitamin supplements

Answer: (A)

Tracking fluid balance hinges on accurate measurement of all fluids going in and all fluids going out. In fluid volume excess, documenting intake and output provides the most direct, objective picture of fluid accumulation or loss, allowing calculation of net fluid balance and guiding management—such as diuretic adjustments or fluid restrictions—while monitoring trends over time. Daily weights and edema assessment often accompany I&O, but the essential monitoring tool is keeping precise intake and output records. The other options don’t provide data on fluid status: increasing protein affects nutrition status, while sleeping more or taking vitamins don’t monitor or influence fluid balance.
