A 45-year-old homeless man is brought to the emergency department by the police. He was found intoxicated. The patient has a medical history of IV drug abuse, diabetes, alcohol abuse, and malnutrition. The patient has been hospitalized previously for multiple episodes of pancreatitis and sepsis. Currently, the patient is minimally responsive and only withdraws his extremities in response to painful stimuli. His temperature is 99.5°F (37.5°C), blood pressure is 90/48 mmHg, pulse is 150/min, respirations are 17/min, and oxygen saturation is 95% on room air. A physical exam is notable for tachycardia, a diastolic murmur at the left lower sternal border, and bilateral crackles on a pulmonary exam. The patient is started on IV fluids, vancomycin, and piperacillin-tazobactam. Laboratory values are ordered as seen below:

Hemoglobin: 9 g/dL
Hematocrit: 30%
Leukocyte count: 11,500/mm^3 with normal differential
Platelet count: 297,000/mm^3

Na+: 139 mEq/L
Cl-: 100 mEq/L
K+: 4.0 mEq/L
HCO3-: 28 mEq/L
BUN: 33 mg/dL
Glucose: 60 mg/dL
Creatinine: 1.7 mg/dL
Ca2+: 9.7 mg/dL
PT: 20 seconds

The patient is admitted to the medical floor. Five days later, the patient's neurological status has improved. His temperature is 99.5°F (37.5°C), blood pressure is 130/90 mmHg, pulse is 90/min, respirations are 11/min, and oxygen saturation is 99% on room air. Laboratory values are repeated as seen below:

Hemoglobin: 10 g/dL
Hematocrit: 32%
Leukocyte count: 9,500/mm^3 with normal differential
Platelet count: 199,000/mm^3

Serum:
Na+: 140 mEq/L
Cl-: 102 mEq/L
K+: 4.3 mEq/L
HCO3-: 24 mEq/L
BUN: 31 mg/dL
Glucose: 100 mg/dL
Creatinine: 1.6 mg/dL
Ca2+: 9.0 mg/dL
PT: 50 seconds
aPTT: 110 seconds
AST: 150 U/L
ALT: 90 U/L
