The nurse assesses a client in the diuretic phase of an acute kidney injury. Which findings should the nurse anticipate? Select all that apply.

Rationale: A. Hypokalemia is expected during the diuretic phase of acute kidney injury. As the kidneys begin to recover and urine output increases, large amounts of potassium are lost in the urine. This can lead to low serum potassium levels, which requires careful monitoring and replacement if necessary. B. Copious amounts of urine output are characteristic of the diuretic phase. After the oliguric phase, the kidneys start to excrete large volumes of urine as they begin to recover, often leading to high urine output that can reach several liters per day. C. Increasing blood urea nitrogen (BUN) is more typical of the oliguric phase of acute kidney injury, when waste products accumulate due to decreased renal excretion. During the diuretic phase, BUN levels usually begin to stabilize or decrease as kidney function improves. D. Dehydration is common in the diuretic phase due to excessive fluid loss from the high urine output. Clients are at risk of hypovolemia and hypotension, making fluid replacement and careful monitoring essential. E. Increasing creatinine level is also associated with the oliguric phase rather than the diuretic phase. During the diuretic phase, creatinine levels generally plateau or begin to decrease as kidney filtration improves.
