What is the purpose of intake and output documentation?

• A. To monitor a resident’s fluid balance and detect dehydration or fluid overload; report significant discrepancies.
• B. To track room temperature and lighting preferences.
• C. To document favorite foods for dietary planning.
• D. To evaluate a resident's activity level.

Answer: (A)

Intake and output documentation focuses on fluid balance—keeping track of how much fluid a resident takes in and how much leaves the body. This helps detect dehydration or fluid overload and highlights discrepancies between what is consumed and what is eliminated. You record all fluids the resident takes (drinks, ice chips, fluids in meals, tube feeds) and all outputs (urine, stool, vomit, wound drainage). The information guides the care team in decisions about hydration, IV fluids, or fluid restrictions, and it’s important for catching problems early. When there are significant differences, the nurse needs to assess and respond promptly. Other tasks like tracking room temperature, noting favorite foods, or evaluating activity levels aren’t about fluid balance, so they aren’t the purpose of I&O documentation.
