Final answer:
In acute renal failure, expect to see a sudden decline in kidney function, leading to waste accumulation, imbalance of fluids and electrolytes, and possible anemia, along with hyperkalemia, metabolic acidosis, uremia, and potential heart rhythm changes.
Step-by-step explanation:
If a patient has acute renal failure, also known as acute kidney injury (AKI), you would expect to see a sudden decrease in kidney function. This condition leads to an accumulation of waste products in the blood, an inability to regulate fluid and electrolyte balances, and a potential impact on the production of red blood cells causing anemia. Some of the common problems or complications associated with acute renal failure include symptoms such as fatigue, confusion, nausea, and edema. Additionally, complications may involve hyperkalemia (elevated potassium levels), metabolic acidosis (an acid-base balance disturbance), uremia (build-up of waste products in the blood), alterations in heart rhythm, and in severe cases, an increase in the risk of mortality.
