Final answer:
To achieve a fluid requirement of 60 mL/kg/day for a 2 kg baby, 5 mL/hr are needed.
Step-by-step explanation:
To calculate the mL/hr needed to achieve a fluid requirement, we can use the formula: (Fluid requirement in mL/kg/day) x (Baby's weight in kg) / 24 hours.
In this case, the fluid requirement is 60 mL/kg/day and the baby weighs 2 kg. So, the calculation would be: (60 mL/kg/day) x (2 kg) / 24 hours = 5 mL/hr.
Therefore, the correct option is A. 5 mL/hr.
