Mild, Discharge: 

This patient presents with generalized weakness and fatigue likely secondary to dehydration. Suspect acute kidney injury of prerenal origin. Doubt intrinsic renal dysfunction or obstructive nephropathy. Considered alternate etiologies of the patient’s symptoms including infectious processes, severe metabolic derangements or electrolyte abnormalities, ischemia/ACS, heart failure, and intracranial/central processes but think these are unlikely given the history and physical exam.

Plan: labs, ***fluid resuscitation, pain/nausea control, reassessment
