Jane, diagnosed with diabetes 10 years ago, develops visual impairment, primarily because of:
Microvascular changes in the eye
Development of exophthalmos
Abnormal metabolism in the lens
Cataract development
The Correct Answer is A
A. Diabetic retinopathy, a common complication of diabetes, is caused by microvascular changes in the eye. Chronic high blood sugar can damage the small blood vessels in the retina, leading to visual impairment. This is the most common cause of visual impairment in people with long-standing diabetes.
B. Exophthalmos is typically associated with thyroid disorders, particularly Graves' disease, not diabetes.
C. Abnormal metabolism in the lens can lead to cataracts, but it is not the primary cause of visual impairment in diabetic patients.
D. Cataracts are more common in people with diabetes, but they are not the primary cause of visual impairment in diabetes. Diabetic retinopathy due to microvascular damage is the leading cause.

Correct Answer is A
Explanation
A. Hyperglycemic hyperosmolar-nonketotic syndrome (HHNS) is more commonly associated with type 2 diabetes. It is characterized by very high blood sugar levels and dehydration, but without significant ketone production. It typically occurs in older adults with type 2 diabetes who experience severe dehydration and illness.
B. Hypoglycemia is more commonly associated with type 1 diabetes due to the frequent need for insulin therapy, which can cause low blood sugar levels. In type 2 diabetes, hypoglycemia is less common unless the patient is on insulin or certain oral medications.
C. Diabetic ketoacidosis (DKA) is primarily a complication of type 1 diabetes. It occurs when there is a severe insulin deficiency, leading to the breakdown of fat for energy and the production of ketones. While DKA can occur in type 2 diabetes, it is far more common in type 1.
D. The Somogyi effect refers to rebound hyperglycemia following an episode of hypoglycemia, typically occurring overnight. It is more commonly seen in type 1 diabetes, especially when insulin doses are too high, causing low blood sugar at night followed by a rebound increase in blood sugar.
Correct Answer is D
Explanation
A. Identifying specific pathogens is important for guiding treatment, but the immediate focus in septic shock is on supporting circulation and treating the source of infection rather than just identification.
B. Improving tissue perfusion through intravenous fluid and blood replacement is part of the treatment but is not the sole focus. It is a supportive measure, and it is done alongside treating the source of infection.
C. Administering antibiotics is critical in septic shock but is only part of the treatment. It should be done alongside efforts to support circulation and treat the source of infection.
D. Treating the source of infection and supporting circulation are the primary goals in managing septic shock. This includes administering fluids, antibiotics, and sometimes vasopressors, in addition to addressing the underlying infection.
