If a patient’s urine output is too low, what is the appropriate action?

When a patient's urine output is too low, increasing fluid intake by 25% can be the appropriate action. This is because low urine output may indicate dehydration or an inadequate fluid volume, leading to decreased kidney perfusion. By increasing fluid intake, you can help restore hydration status, improve kidney perfusion, and promote urine production.

Monitoring urine output is crucial in assessing a patient's fluid balance and renal function. If the underlying cause of low urine output is related to dehydration, administering more fluids can help address the deficiency, allowing the kidneys to function more effectively. It's essential to continuously monitor the patient’s response to the increased fluid intake to ensure it results in improved urine output.

Other options, while they might seem plausible in different contexts, would not typically address the immediate concern of low urine output effectively in a straightforward situation. For instance, decreasing fluid could exacerbate the issue, while changing the diet may not impact fluid levels directly, and administering diuretics could further reduce urine output or lead to dehydration if the patient's fluid status is not adequately addressed first.
