QUESTIONS WITH COMPLETE SOLUTIONS

CDE
1. Pathophysiology (Type 1 Diabetes)
Question:
Which of the following best explains the pathophysiological mechanism of Type 1 Diabetes
Mellitus?
A. Insulin resistance due to adipose inflammation
B. Autoimmune destruction of pancreatic beta cells
C. Decreased incretin hormone secretion
D. Increased hepatic glucose production
Answer:
B. Autoimmune destruction of pancreatic beta cells
Rationale:
Type 1 diabetes results from an autoimmune attack against insulin-producing beta cells in the
pancreas. This leads to absolute insulin deficiency, unlike Type 2 diabetes, which involves
insulin resistance and relative insulin deficiency.
2. Pharmacology (Insulin Regimens)
Question:
A 35-year-old male with Type 1 diabetes is on a basal-bolus insulin regimen. He injects insulin
glargine once daily and insulin aspart before meals. What is the primary purpose of the insulin
glargine?
A. To cover postprandial glucose spikes
B. To prevent nocturnal hypoglycemia
C. To mimic pancreatic basal insulin secretion
D. To enhance incretin effect
Answer:
C. To mimic pancreatic basal insulin secretion
Rationale:
Insulin glargine is a long-acting insulin analogue that provides steady-state insulin coverage over
24 hours, simulating basal insulin secretion.
,3. Nutrition (Carbohydrate Counting)
Question:
A patient is using carbohydrate counting to manage blood glucose. If their insulin-to-carb ratio is
1:10 and they plan to eat a meal with 60g of carbohydrates, how many units of rapid-acting
insulin should they take?
A. 6 units
B. 10 units
C. 60 units
D. 1 unit
Answer:
A. 6 units
Rationale:
Carb ratio 1:10 means 1 unit insulin per 10g carbs. For 60g carbs:
60 ÷ 10 = 6 units
4. Monitoring & Targets
Question:
What is the recommended target A1C for most non-pregnant adults with diabetes, according to
Diabetes Canada guidelines?
A. <8.0%
B. <6.5%
C. ≤7.0%
D. ≤5.6%
Answer:
C. ≤7.0%
Rationale:
Diabetes Canada recommends an A1C target of ≤7.0% for most non-pregnant adults to reduce
microvascular and macrovascular risks.
5. Hypoglycemia Management
Question:
A patient with Type 2 diabetes experiences hypoglycemia with a blood glucose of 3.2 mmol/L.
What is the appropriate initial treatment?
A. Administer 30g protein
B. Inject glucagon
,C. Provide 15g of fast-acting carbohydrate
D. Call 911 immediately
Answer:
C. Provide 15g of fast-acting carbohydrate
Rationale:
Mild to moderate hypoglycemia is treated with 15g of fast-acting carbohydrate (e.g., glucose
tablets, juice). Recheck blood sugar in 15 minutes.
6. Pharmacology (Oral Antihyperglycemics)
Question:
Which of the following oral agents reduces cardiovascular risk and promotes weight loss in
patients with Type 2 diabetes?
A. Sulfonylureas
B. Metformin
C. SGLT2 inhibitors
D. DPP-4 inhibitors
Answer:
C. SGLT2 inhibitors
Rationale:
SGLT2 inhibitors (e.g., empagliflozin) lower blood glucose by promoting urinary glucose
excretion and have demonstrated cardiovascular and renal benefits, as well as modest weight
loss.
7. Professional Practice (Scope & Standards)
Question:
Which of the following is a core responsibility of a Certified Diabetes Educator (CDE) in
Canada?
A. Prescribing insulin adjustments without collaboration
B. Diagnosing diabetes based on lab tests
C. Providing evidence-based education on self-management
D. Conducting lab work independently
Answer:
C. Providing evidence-based education on self-management
, Rationale:
CDEs play an educational and supportive role, empowering individuals through evidence-based
guidance. Prescribing or diagnosing is beyond their scope unless they have additional credentials
(e.g., NP, MD).
8. Counselling (Motivational Interviewing)
Question:
Which of the following is consistent with motivational interviewing techniques?
A. Giving direct orders to change behaviour
B. Emphasizing patient autonomy and evoking personal reasons for change
C. Providing all the answers without patient input
D. Using guilt to promote adherence
Answer:
B. Emphasizing patient autonomy and evoking personal reasons for change
Rationale:
Motivational interviewing is a collaborative, person-centered approach that enhances intrinsic
motivation for change by exploring and resolving ambivalence.
9. Complications (Diabetic Neuropathy)
Question:
A patient reports burning foot pain at night and decreased vibration sensation. What is the most
likely complication?
A. Autonomic neuropathy
B. Retinopathy
C. Peripheral neuropathy
D. Hypoglycemia unawareness
Answer:
C. Peripheral neuropathy
Rationale:
Burning pain and sensory loss are classic signs of distal symmetric polyneuropathy (peripheral
neuropathy), a common complication of diabetes.
