Which is the most reliable method for monitoring fluid balance?
Correct Answer: A
Rationale: Monitoring daily intake and output is the most reliable method for assessing fluid balance in a patient. By accurately measuring the amount of fluids taken in through foods, drinks, and IV fluids, as well as the amount of fluids eliminated through urine, stool, vomit, and other means, healthcare providers can closely track the body's fluid balance. Discrepancies between intake and output can indicate potential issues such as dehydration or fluid overload. This method provides quantitative data that can guide appropriate interventions and treatment adjustments to maintain the patient's fluid balance within normal limits. While vital signs, daily weight, and skin turgor are also important indicators of fluid status, they may not always provide as specific or accurate information as the direct measurement of intake and output.
