Which abbreviation is used to denote the measurement of all fluids entering and leaving the body?

• A. BSC
• B. UO
• C. I&O
• D. BM

Answer: (C)

Tracking fluid balance means noting everything a patient takes in and everything that leaves the body. The abbreviation used for this full measurement is I&O—short for intake and output. Keeping an I&O record helps assess hydration, kidney function, and whether treatment like IV fluids or diuretics is needed. Intake includes oral drinks, IV fluids, tube feedings, and any other fluids the patient receives. Output includes urine, vomiting, drainage from wounds or tubes, and other measurable losses. The other options don’t cover all fluids: urine output alone reflects only urine, not total intake and losses; a bedside commode is a device, not the measurement term; and a bowel movement refers to stool and doesn’t indicate overall fluid balance.
