Due to author error, the bolded information in the paragraph below should have stated: “creatinine 3.6 mg/dl” but incorrectly stated “creatinine 3.6 mEq/L”. The authors regret any confusion this may have caused to readers.

Patient A

A 72-year-old woman with hypertension and stage 4 CKD (baseline creatinine 2.4–2.8 mg/dl) is admitted to the hospital with malaise and confusion. Approximately 10 days before, her primary care practitioner had increased enalapril to 20 mg twice daily (from 10 mg twice daily) and added furosemide 20 mg twice daily to get better control of BP. At that visit, her serum sodium was 124 mEq/L, and creatinine was 3.0 mg/dl. Over the next week, she has become lethargic with decreased urine output and confused. At the urging of her daughter, she has been drinking excessive amounts of fluid (>2 L/d) over the past week. On presentation, she was not oriented to person or place, and her vital signs were notable for an elevated respiratory rate and an oxygen saturation of 82% on room air but otherwise normal. Physical examination revealed jugular venous distention, bibasilar rales, and an S4 on cardiac examination. Blood chemistries were notable for the following: sodium 112 mEq/L, potassium 6.8 mEq/L, chloride 80 mEq/L, bicarbonate 16 mEq/L, BUN 93 mg/dl, and creatinine 3.6 mEq/L.
