Diabetes Daily Management

Your patient's A1C is 9.2% despite taking insulin — the problem isn't the medication, it's what happens between doses. Daily management decisions determine whether diabetes stays controlled or spirals.

Daily diabetes management centers on blood glucose monitoring, insulin administration technique, and sick-day rules. Fasting blood glucose target is 80–130 mg/dL; postprandial (1–2 hours after eating) target is less than 180 mg/dL. A1C reflects a 2–3 month average and should be below 7% for most adults. Self-monitoring of blood glucose (SMBG) guides real-time insulin and meal adjustments. Insulin must be stored properly — unopened vials refrigerated, opened vials at room temperature up to 28 days. Injection sites rotate within the same anatomic region (e.g., abdomen) to prevent lipodystrophy, and the abdomen provides the fastest, most consistent absorption. When mixing insulins in one syringe, draw clear (regular) before cloudy (NPH) — 'clear before cloudy.' During illness, the client never skips insulin even if not eating, because stress hormones drive hyperglycemia. Sick-day rules include checking glucose every 4 hours, maintaining hydration, testing urine for ketones when glucose exceeds 240 mg/dL, and contacting the provider if vomiting persists or ketones are moderate to large.

Key Distinctions

Don't confuse fasting glucose targets (80–130 mg/dL) with random or postprandial targets (<180 mg/dL) — NCLEX questions test which threshold applies to which timing. Students commonly think insulin should be held when a sick client isn't eating — the opposite is true; illness raises glucose. Rotating injection sites means rotating within one region (different spots on the abdomen), not jumping between abdomen and thigh daily, which causes unpredictable absorption.

Clinical Pearl

Clear before cloudy, never skip insulin when sick, and always rotate within — not between — body regions. These three rules cover the most-missed NCLEX items on daily management.
