Physical exam reveals a distended abdomen that is non-tender. Neurological exam is notable for a confused patient and asterixis. Laboratory values are ordered as seen below.  Serum: Na+: 139 mEq/L Cl-: 100 mEq/L K+: 3.3 mEq/L HCO3-: 22 mEq/L BUN: 20 mg/dL Glucose: 59 mg/dL Creatinine: 1.1 mg/dL Ca2+: 10.2 mg/dL  Which of the following is the best next treatment for this patient?   (A) Dextrose   (B) Lactulose   (C) Potassium   (D) Rifaximin
