Visual impairment may develop in people with diabetes, primarily because of:
Cataract development.
Development of exophthalmos
Abnormal metabolism in the lens.
Microvascular changes in the eye.
The Correct Answer is D
Choice A reason: Cataract development is a common issue in people with diabetes due to the high blood sugar levels that affect the lens of the eye. However, it is not the primary cause of visual impairment. Cataracts cause the lens to become cloudy, leading to blurred vision, but the impact is generally less severe compared to the microvascular complications of diabetes.
Choice B reason: Exophthalmos, or bulging of the eye, is not typically associated with diabetes. It is more commonly seen in conditions like Graves' disease, an autoimmune disorder affecting the thyroid. Therefore, while it is important to be aware of various conditions that can impact eye health, exophthalmos is not a primary complication of diabetes.
Choice C reason: Abnormal metabolism in the lens can contribute to the formation of cataracts, but it is not the main reason for diabetic visual impairment. The primary issue in diabetes-related visual impairment is damage to the small blood vessels in the retina, not just changes in the lens metabolism.
Choice D reason: Microvascular changes in the eye, particularly diabetic retinopathy, are the primary cause of visual impairment in people with diabetes. High blood sugar levels can damage the blood vessels in the retina, leading to leakage, swelling, and the formation of new, abnormal blood vessels. This can result in significant vision loss and even blindness if not properly managed. Regular eye examinations and control of blood glucose levels are crucial in preventing and managing diabetic retinopathy.

Correct Answer is D
Explanation
Choice A reason: Fever is not typically the first clinical manifestation of tumors in these areas. Fever may occur as a systemic response to cancer, but it is not usually the initial sign.
Choice B reason: Swelling can be a symptom of tumors, but it is not as specific or as commonly the first clinical manifestation as a palpable mass.
Choice C reason: Pain can be associated with tumors, but it is not usually the first clinical manifestation. Pain may develop as the tumor grows and affects surrounding tissues.
Choice D reason: A palpable mass is often the first clinical manifestation of tumors in the breast, testicle, and lymph nodes. In the breast, it may present as a new lump or mass that can be felt during a physical examination. In the testicle, it may present as a lump or swelling. In the lymph nodes, it may present as enlarged or firm lymph nodes that can be felt under the skin.
Correct Answer is B
Explanation
Choice A reason: The overall goal of treatment for both type 1 and type 2 diabetes is to maintain blood glucose levels within a normal range and prevent complications. While the strategies to achieve these goals may differ, the ultimate objectives are similar for both types of diabetes.
Choice B reason: The treatment for type 1 diabetes primarily involves insulin therapy, as the body cannot produce insulin. In contrast, type 2 diabetes treatment often starts with lifestyle changes and oral medications to improve insulin sensitivity and control blood glucose levels. Insulin therapy may be required later in the course of type 2 diabetes if other treatments are insufficient.
Choice C reason: Both types of diabetes are diagnosed using similar criteria, including measuring blood glucose levels through fasting blood glucose tests, oral glucose tolerance tests, and HbA1c levels. The diagnosis process itself is not a major differentiating factor between the two types.
Choice D reason: The potential long-term complications of both type 1 and type 2 diabetes are similar and include cardiovascular disease, neuropathy, nephropathy, retinopathy, and other complications related to prolonged high blood glucose levels. While the risk factors and progression may vary, the types of complications are not significantly different between the two conditions.
