What should be administered if a VAD patient's blood glucose is less than 60 mg/dl?

In the scenario of a VAD (Ventricular Assist Device) patient presenting with hypoglycemia, which is indicated by a blood glucose level of less than 60 mg/dl, administering 100 mL of D10 is appropriate because D10, or 10% dextrose solution, effectively raises the blood glucose level quickly compared to lower concentrations.

D10 is specifically chosen because it is concentrated enough to provide a rapid influx of glucose into the bloodstream, which is crucial in managing hypoglycemic episodes. When blood glucose drops below the threshold, immediate correction is necessary to prevent neurological damage and other morbidity associated with low blood sugar. Administering the correct amount helps ensure that the correction is both effective and safe for the patient.

The other options, while they may provide fluids, do not deliver the necessary glucose concentration required for effective treatment of hypoglycemia in this context.
