✍️ Sample CDCES Questions & Answers

1. Which communication technique is most effective for verifying understanding?

✓ Asking the person to explain the information back in their own words

The teach-back method confirms understanding by having the person explain the information in their own words.

2. Which professional credential held by a CDCES applicant would satisfy the healthcare provider licensure requirement for CDCES eligibility?

✓ Registered Nurse (RN)

CDCES eligibility requires licensure or certification as a healthcare professional; Registered Nurse (RN) is one of the accepted licensed healthcare professions.

3. What is an insulin pump (CSII) used for in diabetes management?

✓ Delivering continuous subcutaneous insulin infusion to replace multiple daily injections

CSII (Continuous Subcutaneous Insulin Infusion) delivers a programmed basal rate of insulin plus patient-activated bolus doses via a small catheter inserted under the skin.

4. A patient using an insulin pump has a glucose of 310 mg/dL and moderate blood ketones, and a correction bolus 2 hours ago did not work. What is the most appropriate next step?

✓ Give correction insulin by pen or syringe and change the infusion set

Persistent hyperglycemia with ketones on a pump suggests insulin delivery failure, so give insulin by injection and replace the infusion set.

5. Written diabetes education materials for the general public should ideally be at what reading level?

✓ 6th grade or lower

Health literacy guidelines recommend writing patient materials at about a 6th-grade level or lower so most adults can understand them.

6. Which of the following best explains the phenomenon of the dawn phenomenon in diabetes?

✓ Early morning hyperglycemia caused by overnight counter-regulatory hormone release (growth hormone, cortisol) that increases insulin resistance

The dawn phenomenon is early morning hyperglycemia caused by physiological surges in growth hormone, cortisol, and catecholamines during the early morning hours that increase hepatic glucose production and insulin resistance.
