When a patient is described as having oliguria, it signifies that they are producing a significantly reduced amount of urine, specifically less than 400 milliliters per day in adults. This condition can indicate various underlying health issues, such as dehydration, kidney problems, or urinary tract obstructions. Recognizing oliguria is crucial in a clinical setting as it may require further investigation and intervention to address the patient’s condition and overall fluid balance.
The other options do not align with the definition of oliguria. Excessive urine production is referred to as polyuria, while foul-smelling urine could indicate an infection or other issues, and discolored urine may suggest various conditions but does not reflect the quantity of urine produced. Thus, understanding the term aligns directly with the patient’s reduced urine output.
