CASE 4: (There will be 8 questions on this case) A canine patient presents with a history of polyuria (frequent urination), polydipsia (frequent drinking) and vomiting. Physical findings include a > 5% dehydration, apparent disorientation and Kussmaul respirations (rapid, deep breathing). Blood work reveals elevated blood glucose (> 300 mg/dL), severe ketoacidosis (very high ketone levels and acidosis) and non-detectable insulin levels. You make a diagnosis of severe diabetic ketoacidosis (DKA) secondary to type I diabetes. CASE 4, Q1: In this patient, liver gluconeogenesis is…
