The following are lipid abnormalities. Which of the following is a risk factor for the development of atherosclerosis and peripheral vascular disease (PVD)?
High levels of low-density lipid (LDL)
Low concentration triglycerides
Low levels of LDL cholesterol
High levels of high-density lipid (HDL)
The Correct Answer is A
A. LDL cholesterol, often referred to as "bad" cholesterol, is a major risk factor for atherosclerosis and PVD. High levels of LDL contribute to the buildup of plaque in the arteries, which can lead to these conditions.
B. While high triglycerides can be a risk factor, low triglycerides are generally not associated with increased risk of atherosclerosis or PVD.
C. Low LDL cholesterol is actually considered beneficial and can reduce the risk of heart disease.
D. HDL cholesterol, often called "good" cholesterol, helps remove LDL cholesterol from the bloodstream. High levels of HDL are actually protective against heart disease and PVD.

A. Trauma to the eye can lead to retinal detachment. Understanding any history of eye injuries is crucial for assessing the likelihood of detachment.
B. Lifting heavy objects can increase intraocular pressure, which may contribute to retinal detachment, particularly in individuals with existing vulnerabilities. This question is relevant for assessing risk factors.
C. While sodium intake is important for general health, it is not directly related to the risk of retinal detachment. This question is not relevant in this context.
D. This statement is somewhat correct but less directly relevant. While protecting the eyes from UV light is important for overall eye health and can help prevent conditions that might lead to retinal issues, it is not a primary factor associated with retinal detachment.
E. Long-term use of steroids can increase the risk of retinal detachment, particularly in patients with certain conditions (like high myopia). This question is important for identifying potential risk factors.
