A nurse is calculating the fluid intake for a healthy newborn who weighs 3 kg.
How much fluid does the newborn need per day?
Wrong because 300 to 420 mL is too low for a 3 kg newborn.
Wrong because 330 to 462 mL is also too low for a 3 kg newborn.
This is because the fluid intake for a healthy newborn is about 120 to 168 mL/kg/day.
Wrong because 390 to 546 mL is too high for a 3 kg newborn.
360 to 504 mL. This is because the fluid intake for a healthy newborn is about 120 to 168 mL/kg/day.
Since the newborn weighs 3 kg, the fluid intake per day is 3 x 120 to 3 x 168 mL, which equals 360 to 504 mL.
Choice A is wrong because 300 to 420 mL is too low for a 3 kg newborn.
Choice B is wrong because 330 to 462 mL is also too low for a 3 kg newborn.
Choice D is wrong because 390 to 546 mL is too high for a 3 kg newborn.
Normal ranges for fluid intake vary depending on the age and weight of the infant. For example, infants 0–6 months of age need about 700 mL of fluid per day, assumed to be from milk. Infants 7–12 months of age need about 800 mL of fluid per day from milk and complementary foods and beverages. Children 1–3 years of age need about 1300 mL of fluid per day.
