NCLEX Must-Know: Diabetes Type 1&2!
If you’re studying for the NCLEX or in nursing school, you will see diabetes-related questions. Here are the key takeaways:
Diabetes Type 1:
• Autoimmune disorder → NO insulin production
• Requires lifelong insulin therapy
• Risk for DKA (Diabetic Ketoacidosis) → High blood sugar, ketones in urine, fruity breath, Kussmaul breathing
• Symptoms: Polyuria, polydipsia, polyphagia, weight loss
Diabetes Type 2:
• Insulin resistance → Body still produces insulin but can’t use it effectively
• Managed with lifestyle changes, oral meds, and sometimes insulin
• Risk for HHNS (Hyperosmolar Hyperglycemic Nonketotic Syndrome) → Extremely high blood sugar, dehydration, NO ketones
• Symptoms: Fatigue, slow wound healing, recurrent infections
Key Labs:
• Normal fasting glucose: 70-100 mg/dL
• Diabetes diagnosis: A1C ≥ 6.5%, Fasting glucose ≥ 126 mg/dL
NCLEX Tips:
• Know the difference between DKA & HHNS
• Watch for hypoglycemia symptoms: Shaky, sweaty, confused → Give 15g fast-acting carbs
• Sick day rules: Take insulin even if not eating, monitor glucose every 2-4 hours
You will see this on the NCLEX, so be prepared!

Diabetes is a crucial topic for nursing students, especially those preparing for the NCLEX. Understanding the nuances between Type 1 and Type 2 is essential. Type 1 diabetes is primarily an autoimmune disorder, meaning the body's immune system attacks insulin-producing cells, leading to a complete lack of insulin production. This condition necessitates lifelong insulin therapy to manage blood glucose levels. Patients may encounter ketones in urine due to Diabetic Ketoacidosis (DKA), presenting with serious symptoms like high blood sugar and fruity breath. Conversely, Type 2 diabetes involves insulin resistance, wherein the body continues to produce insulin but cannot utilize it effectively. This type can often be managed through lifestyle adjustments, oral medications, and sometimes insulin, especially when hyperosmolar hyperglycemic nonketotic syndrome (HHNS) occurs, indicated by very high blood sugar but without ketones. Key lab values to remember include a normal fasting glucose range of 70-100 mg/dL, with diabetes diagnosed through an A1C of 6.5% or greater or fasting glucose of 126 mg/dL or higher. It is vital to recognize and differentiate symptoms associated with these two types of diabetes for both patient safety and exam readiness. Furthermore, mastery of glucose regulation is invaluable in nursing practice, ensuring effective patient care and preparation for the NCLEX.
I’m type two I feel awesome if I walk in the morning and before bed (purchased a walking pad) also a grapefruit right after each. … (also on Metformin) I don’t want to be so for now I have to get up and move and not consume bad starches.
