A nurse is providing teaching to a group of clients about the changes that occur when clients experience cataracts. Which of the following statements should the nurse include in the teaching?
"Vision changes occur when pressure in the eye is increased due to a decrease of aqueous humor."
"Vision changes occur when blood vessels leak fluid or blood under a portion of the retina."
"Vision changes occur when the cloudy lens alters the passage of light through the eye."
"Vision changes occur when retinal tissue pulls away from the blood vessels in the eye."
The Correct Answer is C
A) "Vision changes occur when pressure in the eye is increased due to a decrease of aqueous humor." This statement describes a mechanism associated with glaucoma, not cataracts. In cataracts, vision changes occur due to the opacity or cloudiness of the lens, not changes in intraocular pressure.
B) "Vision changes occur when blood vessels leak fluid or blood under a portion of the retina." This statement describes a mechanism associated with retinal diseases like diabetic retinopathy, not cataracts. In cataracts, the lens becomes cloudy, affecting the passage of light through the eye.
C) "Vision changes occur when the cloudy lens alters the passage of light through the eye." This statement is correct. Cataracts cause the lens of the eye to become cloudy, which interferes with the passage of light through the eye. This results in vision changes such as blurred vision, glare, and difficulty seeing in low light conditions.
D) "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye." This statement describes a mechanism associated with retinal detachment, not cataracts. In cataracts, the lens becomes opaque, but the retinal tissue remains intact.

Correct Answer is D
Explanation
A. Diminished hair growth on the lower extremities: Diminished hair growth on the lower extremities is not typically a manifestation of peripheral venous disease. Instead, it may suggest poor circulation or arterial insufficiency.
B. Loss of pigmentation over the shin area: Loss of pigmentation over the shin area can occur in conditions such as chronic venous insufficiency, which is a form of peripheral venous disease. However, it is not the most characteristic manifestation.
C. Shiny appearance to the lower extremities: A shiny appearance to the lower extremities is often associated with arterial insufficiency rather than peripheral venous disease. It can indicate thinning of the skin due to poor circulation and oxygenation.
D. Swollen and enlarged veins: Swollen and enlarged veins, also known as varicose veins, are classic manifestations of peripheral venous disease. These veins result from venous insufficiency, which leads to blood pooling and increased pressure in the veins, causing them to dilate and become visibly enlarged.
Correct Answer is A
Explanation
A. "I need to walk slowly as I lose my balance often": This statement indicates a potential safety concern related to balance issues while walking. Loss of balance can increase the risk of falls, especially in individuals with peripheral artery disease (PAD) who may already have compromised circulation and reduced sensation in their legs. The nurse should report this statement to the provider for further evaluation and intervention to prevent falls and promote safety.
B. "I don't go out much because of the pain in my legs" : While this statement suggests that the client experiences pain in their legs, it does not directly indicate a safety concern that requires immediate reporting to the provider. Pain management strategies may be discussed with the provider to address this issue.
C. "It makes me sad that I can't keep up with my grandchildren" : While this statement reflects emotional distress related to the client's inability to participate fully in activities with their grandchildren, it does not indicate a specific safety concern that requires reporting to the provider. However, addressing the client's emotional well-being is important for overall holistic care.
D. "I have a small-healed area on my spine that is painful" : This statement describes a painful area on the client's spine but does not directly relate to potential safety concerns associated with PAD. The nurse may further assess this issue and include it in the client's overall assessment, but it does not require immediate reporting to the provider for safety concerns related to PAD.
