A 65-year-old man presents to the hospital with complaints of fatigue, nausea, vomiting, and diarrhea for the past five days. He also states numbness and tingling of the legs, joint pain, and decreased urination that developed around the same time. He was recently diagnosed with non-Hodgkin lymphoma and started on chemotherapy two weeks ago. Vital signs show a blood pressure of 95/65 mm Hg, a pulse of 98/min, a respiratory rate of 19/min, and a temperature of 100˚F. Physical examination reveals a pale and cachectic man. Laboratory investigations reveal serum potassium 6.0 mEq/L (normal: 3.5-5.0 mEq/L), serum creatinine 3.2 mg/dL (normal: 0.6-1.2 mg/dL), serum calcium 7.0 mg/dL (normal: 8.6-10.2 mg/dL), and serum uric acid 9 mg/dL (normal: 2.4-6.5 mg/dL).
