A nurse is teaching a diabetic education class when one of the patients asks, “What can I do to prevent going blind due to my diabetes?” What is the best response by the nurse?
1. “The risk of developing blindness is related to how long you’ve had diabetes, and how well your blood sugar and hypertension are controlled.”
2. “It is due to the small blood vessels in the eye becoming hardened and clogged and not being able to transport oxygen and nutrients to the retina.”
3. “This is only a problem with type 2 diabetes so you won’t have this problem.”
4. “Laser photocoagulation surgery will treat any problems that develop and stop the progression of diabetic retinopathy.”
