Final answer:
To maintain accurate I&O's when administering a diuretic, you should closely monitor and record the patient's fluid intake and urine output.
Step-by-step explanation:
When administering a diuretic to a patient and maintaining accurate I&O's, it is important to implement the intervention of closely monitoring and recording the patient's intake and output of fluids. This includes measuring the amount of fluid intake, such as oral or intravenous fluids, as well as measuring and documenting the amount of urine output. By carefully tracking these values, healthcare professionals can determine if the diuretic is effectively increasing urination and reducing fluid retention. This intervention helps to ensure that the patient is responding to the diuretic appropriately and can guide adjustments to the medication if necessary
