Why is daily weight monitoring recommended during IV therapy?

• A. To evaluate fluid balance
• B. To monitor electrolyte concentration
• C. To assess infection risk
• D. To measure blood glucose

Answer: (A)

Tracking fluid status is the key idea. Daily weight reflects net changes in body water, so when IV fluids are given (or removed through diuretics or output), weight helps show whether the patient is gaining or losing fluid. A steady increase suggests fluid overload or edema risk, while a decrease can indicate dehydration or insufficient fluid intake. Keeping track under consistent conditions (same scale, same time of day, similar clothing) makes the changes meaningful and helps guide adjustments to the IV fluid rate or type to maintain balanced fluid status and prevent complications. Electrolyte levels need lab tests, infection risk is assessed by signs and labs, and blood glucose is measured separately, so they aren’t indicated by daily weight in the same direct way.
