A normal blood glucose level in dogs is 3.3 - 6.1 mmol/L. This dog shows a blood glucose level of 1.6 mmol/L and is depressed, ataxic, and disoriented. Treatment of acute hypoglycemia consists of an IV bolus of 1 - 2 mL/kg of 50% dextrose (D-glucose) via central venous line or 2 - 4 mL/kg of 25% dextrose via peripheral vein over three minutes.
What is the molarity of glucose in the blood at normal levels?
