The nurse assesses a client with an acute kidney injury and suspects the client is in the recovery phase. Which findings support the nurse's conclusion? Select all that apply.

Rationale: A. This is not expected in the recovery phase. During recovery, kidney function improves, leading to a gradual decrease in serum creatinine and BUN. Persistent elevation indicates ongoing renal impairment rather than recovery. B. Gastrointestinal symptoms like nausea and vomiting are common during the oliguric phase due to uremia. Resolution of these symptoms indicates improving kidney function and supports the recovery phase. C. Electrolyte imbalances such as hyperkalemia or hypocalcemia during AKI can cause muscle twitching or cramps. Resolution of these neuromuscular symptoms indicates stabilization of electrolytes and kidney recovery. D. This is usually seen during the oliguric phase or when the kidneys are not able to concentrate urine properly. In the recovery phase, urine output normalizes and the kidney begins to regain the ability to concentrate or dilute urine, so urine specific gravity tends to normalize, not remain elevated. E. Hyperkalemia is common during the oliguric phase of AKI. During recovery, urine output increases, allowing the kidneys to excrete excess potassium, leading to a gradual decrease toward normal levels.
