A nurse is calculating a client's fluid intake over the past 8 hr. Which of the following items should the nurse plan to document on the client's intake and output record as 120 mL of fluid?

Choice A rationale Ice chips are documented as half of their frozen volume once they melt into liquid form. Since 1 oz is equivalent to 30 mL, 8 oz of ice chips represents a total frozen volume of 240 mL. When calculating intake, the nurse records 50 percent of this volume, which equals 120 mL. This standard practice ensures accuracy in fluid balance monitoring, as the air pockets in ice reduce the actual liquid yield significantly. Choice B rationale Tea is a liquid at room temperature and is recorded at its full volume. Converting 6 oz to milliliters requires multiplying by the conversion factor of 30 mL per ounce. Therefore, 6 oz of tea equals 180 mL of fluid intake. This exceeds the 120 mL target mentioned in the prompt. Accurate documentation of all oral fluids, including tea, coffee, and water, is essential for clients requiring strict monitoring of their renal or cardiac status. Choice C rationale Standard measuring cups in a clinical setting are typically equivalent to 8 oz or 240 mL. Therefore, 2 cups of soup would equal approximately 16 oz or 480 mL. Since soup is primarily liquid, it is recorded at its full volume in the intake record. This amount is far greater than the 120 mL requested. Nurses must be diligent in converting household measurements to metric units to maintain precise records of a client's total daily intake. Choice D rationale A quart is a large unit of volume measurement equivalent to 32 oz or approximately 4 cups. In the metric system, 1 quart is roughly equal to 946 mL, often rounded to 1000 mL or 1 liter in general clinical estimations. This volume is substantially higher than the 120 mL required for documentation. Monitoring water intake is a critical nursing responsibility, especially for clients at risk for fluid volume overload or those requiring specific hydration protocols.
