What are the three cardinal signs for DM? | Polydipsia, polyphagia, and polyuria |
What are the NI and patient teaching aimed at for DM? | Diet & exercise education; medication dosage, type, & route; alternate injection sites to avoid lipodystrophy; notify HCP when glucose is over 250; glucose may be abnormal when ill; and certain meds (cortisone) may increase glucose levels |
What does a glycosylated hemoglobin (HbA1c) do? | Gives an average glucose level over the last 120 days; is an indication if the patient is being compliant with glucose monitoring |
