A patient diagnosed with macular degeneration asks the nurse to explain his condition. Which statement by the nurse best describes macular degeneration?
"The pressure in the anterior cavity of your eye became elevated, shifting the position of your lens.
"There's an irregular curvature of your cornea, causing your blurred vision'
The portion of your eye call the macula, which is responsible for the central vision, is damaged"
"Your lens became cloudy, causing blurred vision. This cloudiness will increase over time
The Correct Answer is C
A. This statement describes glaucoma, not macular degeneration. Glaucoma is characterized by increased intraocular pressure that can lead to optic nerve damage and vision loss. It does not specifically pertain to damage of the macula or central vision.
B. This statement refers to conditions like astigmatism, where the cornea has an irregular shape, leading to blurred vision. It is not relevant to macular degeneration, which involves damage to the retina rather than the curvature of the cornea.
C. This statement accurately describes macular degeneration. The macula is the part of the retina responsible for sharp central vision, which is crucial for tasks like reading and recognizing faces. In macular degeneration, this area deteriorates, leading to loss of central vision.
D. This statement describes cataracts, where the lens of the eye becomes cloudy, leading to blurred vision. Cataracts and macular degeneration are distinct conditions, with different causes and impacts on vision.

Correct Answer is B
Explanation
A. The area should be cleansed gently before applying the cream to remove any irritants and allow for better absorption of the medication. Proper cleansing can help enhance the effectiveness of the corticosteroid.
B. Topical corticosteroids should be applied in a thin layer to the affected area and gently rubbed in. Applying too much can increase the risk of side effects, and a thin application ensures better absorption without overwhelming the skin.
C. The corticosteroid should be applied only to the affected areas of the skin, not the entire body. Overuse can lead to systemic absorption and potential side effects, particularly in children, whose skin is more permeable.
D. While it is important to cover the affected areas, applying a thick layer is not recommended. A thin layer is usually sufficient and minimizes the risk of side effects from excessive corticosteroid use.
