In motivational interviewing for exercise behavior change, a diabetes educator reflects back ambivalence to a patient who says 'I know I should exercise but I just don't have time.' What is the most therapeutic response?
Answer: Explore the discrepancy between the patient's health goals and current behavior without judgment
Motivational interviewing uses reflective listening and exploring discrepancy between values and behavior to elicit intrinsic motivation for change.
A patient with diabetes who exercises outdoors in summer reports dizziness and fatigue during afternoon workouts. What is the most likely contributing factor and recommended adjustment?
Answer: Heat-induced vasodilation compounding dehydration; shift workouts to early morning or evening
Heat and dehydration cause vasodilation and reduced plasma volume, impairing cardiovascular response to exercise; shifting timing to cooler parts of the day mitigates this.
Which statement best describes the additive benefit of combining aerobic and resistance training ('combined training') compared to either alone in type 2 diabetes?
Answer: Combined training lowers HbA1c more than either modality alone
Meta-analyses show combined aerobic plus resistance training produces greater HbA1c reductions than either modality alone in type 2 diabetes.
A patient with well-controlled type 2 diabetes on metformin only asks whether exercise could ever lower blood glucose too much. What is the most accurate response?
Answer: Hypoglycemia risk is very low with metformin monotherapy, but blood glucose monitoring is still encouraged during new exercise programs
Metformin does not stimulate insulin secretion, so hypoglycemia risk during exercise is minimal; however, monitoring during a new program is prudent practice.
Which SGLT-2 inhibitor-specific consideration is most important when counseling a patient about exercise?
Answer: SGLT-2 inhibitors may increase risk of euglycemic DKA, particularly with prolonged endurance exercise
Prolonged exercise combined with SGLT-2 inhibitor use can precipitate euglycemic DKA due to increased glucagon:insulin ratio and enhanced ketogenesis even when blood glucose appears normal.
A diabetes educator is designing a group exercise program for older adults with type 2 diabetes. Which additional exercise component is most important to include beyond aerobic and resistance training?
Answer: Balance and flexibility training to reduce fall risk
Older adults with diabetes have elevated fall risk due to neuropathy and reduced proprioception; balance and flexibility exercises are a critical third component of their exercise prescription.
What is the recommended post-exercise blood glucose check time for a patient with type 1 diabetes who completed a 45-minute moderate-intensity run, to screen for delayed hypoglycemia?
Answer: At 30 minutes and again at 2 hours post-exercise
Checking glucose at 30 minutes post-exercise captures early drops, and a 2-hour check identifies ongoing decline as muscles continue glycogen resynthesis.
