A nurse is caring for a patient with acute kidney injury (AKI). Which assessment finding would be the MOST concerning and require immediate intervention?
1Blood urea nitrogen (BUN) level of 45 mg/dL
2Serum creatinine level of 2.8 mg/dL
3Serum potassium level of 6.8 mEq/L✓ 정답
4Urine output of 350 mL in 24 hours
해설
Hyperkalemia (serum potassium >5.5 mEq/L) is a life-threatening complication of AKI requiring immediate intervention due to risk of fatal cardiac arrhythmias. Other findings (elevated BUN, creatinine, oliguria) are concerning but less urgent.
