A nurse is teaching a diabetic education class. 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. "Diabetic retinopathy is caused by changes in the small blood vessels of the eye.".
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 cure the diabetic retinopathy.".

Rationale 1: The risk of developing diabetic retinopathy is related to the duration of the diabetes and the degree of glycemic control. Hypertension is also a risk factor.
Rationale 2: Although correct, this statement does not answer the patient's question.
Rationale 3: Diabetic retinopathy is seen in both type 1 and type 2 diabetes.
Rationale 4: Laser photocoagulation is used to treat both forms of diabetic retinopathy, but it does not cure the disease.
