A nurse is teaching a client who has diabetes mellitus about diabetic retinopathy.
Which of the following statements should the nurse make to the client?

Choice A rationale:

Secondary prevention involves early detection and intervention to prevent the progression of a disease. In the case of breast cancer, a mammogram is a secondary prevention measure because it aims to detect cancer at an early stage, especially in individuals with a family history of the disease. Early detection can lead to timely treatment and improved outcomes.

Choice B rationale:

Echocardiograms are typically used to assess the function of the heart and diagnose existing heart conditions. While it is a valuable diagnostic tool, it is not an example of secondary prevention, which is focused on early detection and prevention of disease.

Choice C rationale:

Influenza vaccination is an example of primary prevention, as it aims to prevent the initial occurrence of the disease by providing immunity against the influenza virus. It is not considered a form of secondary prevention.

Choice D rationale:

Not scheduling a series of tests for an asymptomatic client does not fit the definition of secondary prevention. Secondary prevention involves screening and early detection in individuals at risk or with early signs of a disease to prevent its progression. An asymptomatic client without known risk factors may not require such testing as a preventive measure.

The correct answer is d. "Seeing spots is a manifestation of diabetic retinopathy."

Choice A rationale:

• Clouding of the lens is not a manifestation of diabetic retinopathy.It is a characteristic of cataracts,a condition that involves a different eye structure and has a different etiology.
• Diabetic retinopathy specifically affects the retina,which is the light-sensitive tissue lining the back of the eye.It does not directly involve the lens.
• It's crucial to clarify this distinction for the client to ensure accurate understanding of their condition and potential symptoms.

Choice B rationale:

• Increased intraocular pressure is not the cause of diabetic retinopathy.It is the primary feature of glaucoma,another eye condition with distinct causes and consequences.
• Diabetic retinopathy is primarily driven by damage to the blood vessels in the retina due to prolonged high blood sugar levels.
• Explaining this difference to the client can help prevent confusion and promote appropriate preventive measures.

Choice C rationale:

• While regular eye exams are essential for early detection and management of diabetic retinopathy,the recommended frequency is more often than every 2 years.
• The American Diabetes Association recommends that individuals with diabetes have a comprehensive dilated eye exam at least annually.
• More frequent exams may be necessary depending on the individual's risk factors and the severity of their diabetes.

Choice D rationale:

• Seeing spots is a common and significant symptom of diabetic retinopathy.It occurs when blood vessels in the retina leak fluid or bleed,causing disruptions in vision.
• Other potential symptoms of diabetic retinopathy include:
  • Blurred vision
  • Floaters (dark specks or strings that move across the visual field)
  • Difficulty seeing at night or in low light
  • Loss of central vision
  • Distortion of colors
  • Blind spots
