You are getting handoff report from the previous RN and he tells you that your patient has Acute Kidney Injury and is oliguric. What does this tell you about the patient?

A. They have no urine output is incorrect because anuria refers to virtually no urine output (less than 50 mL/day), whereas oliguric AKI indicates reduced, but not absent, urine output. B. They have decreased urine output is correct. In the oliguric phase of acute kidney injury, urine output is less than 400 mL per day in adults. This reflects impaired kidney function, leading to fluid retention, electrolyte imbalances, and accumulation of waste products. Monitoring fluid status, electrolytes, and daily weights is crucial during this phase. C. They have bone disease is incorrect because oliguric AKI is not directly associated with bone disease. Bone disease is more commonly seen in chronic kidney disease due to disturbances in calcium, phosphate, and vitamin D metabolism. D. They have elevated K+ levels is incorrect because although hyperkalemia is common in oliguric AKI, it is a potential consequence, not the definition of oliguric AKI. The defining feature is reduced urine output, not the presence of high potassium.
