Questions and Answers
What is Diabetes?
Diabetes is a condition where the body has problems with insulin production or use, leading to abnormal blood sugar levels.
Type 1 diabetes can be inherited genetically.

Study Notes
Diabetes Overview
- Diabetes results from the body's inability to regulate blood sugar levels effectively.
- Two main types: Type 1 and Type 2, with a third type known as Gestational diabetes.
- Homeostatic mechanism: Insulin lowers blood sugar after eating, while Glucagon raises it during fasting.
Type 1 and Type 2 Diabetes
-
Type 1 Diabetes:
- Can be genetic or autoimmune.
- Results in little to no insulin production due to pancreatic damage.
-
Type 2 Diabetes:
- Often linked to lifestyle factors such as diet and exercise.
- Characterized by insulin resistance where cells do not respond effectively to insulin.
-
Gestational Diabetes:
- Mimics Type 2 and typically resolves after childbirth.
-
Pre-diabetes:
- Elevated blood sugar levels that may progress to Type 2 if untreated, but can be reversible with lifestyle changes.
Blood Glucose Monitoring
- Normal blood glucose levels:
- Targeted between 4mmol/L and 7mmol/L before meals, and 8-9mmol/L after meals.
- Hypoglycemia: Blood sugar below 4mmol/L.
- Hyperglycemia: Blood sugar above 7mmol/L after fasting or over 11mmol/L during other tests.
Insulin Types and Characteristics
-
Rapid-Acting Insulin (e.g., Lispro, Novolog):
- Onset: 30 minutes
- Peak: 1-2 hours
- Duration: 3-5 hours
-
Short-Acting Insulin (e.g., Actrapid, Humulin):
- Onset: 30-60 minutes
- Peak: 3 hours
- Duration: 8 hours
-
Intermediate-Acting Insulin (e.g., Humulin I):
- Onset: 1-2 hours
- Peak: 10 hours
- Duration: 11-24 hours
-
Long-Acting Insulin (e.g., Detemir, Glargine, Degludec):
- Onset: 30-40 minutes
- No peak; duration of 24 hours.
Hyperglycaemic Episodes
- Symptoms: Excessive urination, fatigue, increased thirst and hunger.
- Common causes: Infections, surgery stress, missed insulin doses, and corticosteroids.
- Treatment: Administer insulin to lower blood glucose levels.
Long-Term Complications
- Chronic high blood sugar can lead to vascular damage, risking strokes and organ failure.
- Increased susceptibility to infections due to excess glucose.
- Potential outcomes include Diabetic Ketoacidosis (DKA) and Hyperglycemic Hyperosmolar State (HHS).
Nursing Interventions
- Monitor blood glucose levels regularly.
- Assess patient symptoms and check for DKA.
- Administer fast-acting insulin (e.g., Novarapid) as per protocol.
- Provide IV fluids and potassium supplements if critically low.
- Encourage hydration if the patient is conscious.
- Evaluate insulin delivery systems for functionality.
- Document all symptoms and nursing actions for team awareness.
