Final answer:
In caring for a patient with acute kidney injury (AKI), the nurse should be aware of the most common cause of death, fluid intake restrictions during the oliguric phase, and the importance of taking accurate daily weights.
Step-by-step explanation:
In caring for a patient with acute kidney injury (AKI), the nurse should be aware of several important factors. Firstly, the most common cause of death in AKI is not irreversible metabolic acidosis, but rather fluid and electrolyte imbalances and complications of organ dysfunction. Secondly, during the oliguric phase of AKI, daily fluid intake is limited to 1000 mL plus the prior day's measured fluid loss in order to prevent fluid overload. Finally, one of the most important nursing measures in managing fluid balance in the patient with AKI is taking accurate daily weights to monitor for changes in fluid status.
