CDE Exercise Prescription 2 — Questions and Answers
Question 1: A patient with type 2 diabetes wants to start resistance training. What is the recommended minimum frequency per week?
- Once per week
- 2-3 times per week (Correct answer)
- 5-6 times per week
- Every day
Correct answer: 2-3 times per week
Resistance training is recommended 2-3 non-consecutive days per week for people with diabetes.
Question 2: Which of the following best describes the Borg Rating of Perceived Exertion (RPE) scale range for moderate-intensity exercise?
- 6-9
- 12-14 (Correct answer)
- 15-17
- 18-20
Correct answer: 12-14
Moderate-intensity exercise corresponds to an RPE of 12-14 on the 6-20 Borg scale.
Question 3: A person with diabetes is exercising in cold weather. What is the primary concern regarding insulin absorption?
- Cold increases insulin absorption at injection sites
- Cold decreases insulin absorption at injection sites (Correct answer)
- Cold has no effect on insulin absorption
- Cold only affects oral medication absorption
Correct answer: Cold decreases insulin absorption at injection sites
Cold temperatures cause vasoconstriction, which slows insulin absorption from subcutaneous injection sites.
Question 4: What is the recommended duration of moderate-intensity aerobic exercise per week for adults with diabetes according to ADA guidelines?
- 75 minutes
- 100 minutes
- 150 minutes (Correct answer)
- 200 minutes
Correct answer: 150 minutes
The ADA recommends at least 150 minutes of moderate-intensity aerobic activity per week for adults with diabetes.
Question 5: A patient with proliferative diabetic retinopathy should avoid which type of exercise?
- Walking
- Swimming
- High-intensity weightlifting with Valsalva maneuver (Correct answer)
- Cycling on a stationary bike
Correct answer: High-intensity weightlifting with Valsalva maneuver
Heavy resistance exercise with breath-holding (Valsalva) sharply increases intraocular and blood pressure, risking vitreous hemorrhage in proliferative retinopathy.
Question 6: What blood glucose level is generally recommended as the upper threshold above which a person with type 1 diabetes should postpone vigorous exercise?
- 180 mg/dL
- 240 mg/dL
- 300 mg/dL (Correct answer)
- 350 mg/dL
Correct answer: 300 mg/dL
Exercise is generally not recommended when blood glucose exceeds 300 mg/dL, especially with ketones present, as vigorous activity can worsen hyperglycemia.
Question 7: Which exercise type primarily improves insulin sensitivity by increasing GLUT-4 transporter translocation to muscle cell membranes?
- Flexibility training only
- Aerobic and resistance exercise (Correct answer)
- Balance training only
- Breathing exercises only
Correct answer: Aerobic and resistance exercise
Both aerobic and resistance exercise promote GLUT-4 translocation to the cell surface, enhancing glucose uptake independent of insulin.
