✍️ Sample CDE Questions & Answers

1. A patient's blood glucose monitoring technique is being evaluated by a diabetes educator by having her do a test. Which of the following behaviors represents poor technique?
✓ Milking the lanced finger at the tip to acquire a sufficient blood sample

Milking or excessively squeezing the lanced finger to obtain a blood sample is considered poor technique. This action can dilute the blood sample with interstitial fluid, leading to an inaccurate, often falsely low, blood glucose reading. It is recommended to allow a natural drop of blood to form or apply gentle pressure from the base of the finger upwards, rather than squeezing the tip.

2. Peer support in diabetes education is effective primarily because it:
✓ Provides lived-experience modeling and reduces feelings of isolation

Peers with shared experiences normalize the challenges of living with diabetes and serve as credible role models, which Social Cognitive Theory identifies as vicarious learning.

3. Which theory of learning and health behavioral change holds that people learn from their own experiences as well as from watching how others behave and experience things?
✓ Social Cognitive Theory (SCT)

Social Cognitive Theory (SCT) posits that learning occurs in a social context through dynamic interactions between a person, their environment, and their behavior. A key tenet of SCT is observational learning, where individuals learn from their own experiences as well as by observing the behaviors of others and the consequences that follow. This theory emphasizes self-efficacy and the role of social support in health behavior change.

4. What is the primary purpose of a 'suspend on low' feature on a sensor-augmented insulin pump?
✓ Suspend insulin delivery when CGM glucose drops below a set threshold

The 'suspend on low' feature automatically pauses insulin delivery when CGM glucose falls below a programmed threshold to prevent or reduce hypoglycemia.

5. Problem-solving training in diabetes education typically follows which sequence?
✓ Define problem → generate solutions → evaluate options → implement and review

Structured problem-solving follows a logical sequence: clearly define the problem, brainstorm solutions, evaluate them, then act and assess results.

6. Which behavioral model is used to assess a patient's readiness to make diabetes self-care changes?
✓ Transtheoretical Model (Stages of Change)

The Transtheoretical Model (Stages of Change) identifies where a patient falls on the spectrum from precontemplation to active maintenance of behavior change.
