# NCLEX Diabetes Questions — Insulin Types, DKA, HHNS & Teaching Scenarios

If you're studying for the NCLEX-RN, mastering **nclex diabetes mellitus questions** is essential. This is one of the most heavily tested areas on the exam, and understanding it can make the difference between passing and retaking.

Why This Matters for the NCLEX

The NCSBN test plan allocates significant weight to nclex diabetes mellitus questions. Questions in this area test your ability to apply clinical judgment, recognize cues, and prioritize interventions — all core competencies of the Next Generation NCLEX.

Try This NCLEX Practice Question

**A patient with type 1 diabetes is admitted with nausea, vomiting, abdominal pain, and deep rapid respirations (Kussmaul respirations). Blood glucose is 480 mg/dL, serum pH is 7.1, and serum ketones are large. Which order should the nurse question?**

A. Regular insulin IV bolus 0.1 units/kg

B. 0.9% normal saline IV at 500 mL/hr

C. Potassium chloride 20 mEq IV when K+ < 5.5 mEq/L

D. Sodium bicarbonate IV bolus

**Correct Answer: D**

In DKA, insulin therapy and fluid resuscitation will correct the metabolic acidosis. Sodium bicarbonate is NOT recommended unless pH is < 6.9 because it can cause: (1) paradoxical CNS acidosis as bicarbonate crosses the BBB, (2) hypokalemia as potassium shifts intracellularly, and (3) impaired oxygen delivery as the oxyhemoglobin dissociation curve shifts left.

Key Tips for the NCLEX

When approaching nclex diabetes mellitus questions questions on the NCLEX:

• Remember safety first: airway, breathing, circulation (ABCs)
• Know your lab values — they're often the key differentiator between answer choices
