CBDCE content outline and where to practise each area

The content areas below are copied from the official CBDCE content outline published by Certification Board for Diabetes Care and Education. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through CBDCE questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: When using the plate method for diabetes meal planning, what fraction of the plate should be filled with non-starchy vegetables?

1. One-quarter
2. One-half
3. One-third
4. Three-quarters

Answer: B. One-half

Explanation:

The correct answer is One-half. The plate method is a simple visual tool: non-starchy vegetables take up the largest share of the plate, which adds fiber and nutrients while keeping the carbohydrate load modest.

One-quarter is wrong because that is the share usually given to starchy foods or protein, not to vegetables. One-third is wrong because it understates how much of the plate vegetables should fill. Three-quarters is wrong because it would crowd out the protein and carbohydrate portions the method still includes.

Rule to remember: the plate method works by proportion, not by weighing or counting. Vegetables get the biggest portion, and the remaining space is shared between protein and carbohydrate foods.

Example 2

Question: Which evidence-based approach is most important when applying patient safety protocols principles?

1. Following personal clinical intuition only
2. Using the most expensive available treatment
3. Integrating current research with clinical expertise and patient values
4. Relying solely on textbook guidelines from any era

Answer: C. Integrating current research with clinical expertise and patient values

Explanation:

The correct answer is integrating current research with clinical expertise and patient values. Evidence-based practice is a three-part balance, and safety work depends on all of its parts being used together.

Following personal clinical intuition only is wrong because it ignores research and can repeat past mistakes. Using the most expensive available treatment is wrong because cost is not evidence of benefit or safety. Relying solely on textbook guidelines from any era is wrong because guidance ages, and it also leaves out the individual person's situation and preferences.

Rule to remember: when an option leans on a single source, whether intuition, price or a fixed reference, it is usually wrong. The best answer combines evidence, experience and the person's values.

Example 3

Question: Which feature of a CGM system alerts patients to act before glucose levels reach a dangerous threshold?

1. Retrospective download
2. Predictive low alert
3. Calibration reminder
4. Sensor warm-up notification

Answer: B. Predictive low alert

Explanation:

The correct answer is Predictive low alert. This feature uses the recent glucose trend to estimate where levels are heading and warns the person before a dangerous threshold is reached, which leaves time to act.

Retrospective download is wrong because it reviews data after the fact, which helps with pattern review but not with immediate action. Calibration reminder is wrong because it prompts the user to enter a reference value to keep readings accurate; it says nothing about where glucose is heading. Sensor warm-up notification is wrong because it only tells the user when a new sensor is ready to give readings.

Rule to remember: look for the feature that is forward-looking and tied to a threshold. Reports and maintenance prompts are not alerts about danger ahead.

How to use these practice tests

Start with the official material. Read the exam outline and the handbook on cbdce.org so you know the format, the eligibility rules and the three content areas. Then take the general practice test at /cbdce-test as a baseline, without looking anything up, and note which topics felt slow or uncertain.

Use that result to choose your sets. Work on the weakest topics first, such as nutrition and meal planning, diabetes technology and monitoring, or pharmacology basics, and go through them in short sessions rather than one long sitting. After each set, read every explanation, including those for questions you got right, and write a one-line rule for each mistake.

Spend a session on the education, assessment and follow-up sets so you can practise matching an intervention to an individual person. Add the documentation, ethics and safety sets to cover the standards side of the outline.

In the last stretch, return to the full practice test under timed conditions that match your exam format, then review only the rules you wrote down. Our questions are written by us and are not real exam questions, so treat them as practice for reasoning, not as a preview of the exam.
