Aron, a 12-year-old male, is admitted with type 1 diabetes mellitus. For this diagnosis to have been made, Aron had all of the following pathophysiological characteristics except:
Enlarged pancreas.
Hyperglycemia and hyper ketonuria.
A combination of environmental and genetic factors as the cause.
Peak occurrence between ages 7 and 15 years.
The Correct Answer is A
Choice A reason: An enlarged pancreas is not a characteristic of type 1 diabetes. In type 1 diabetes, the immune system attacks and destroys the insulin-producing beta cells in the pancreas, leading to a decrease in insulin production. This does not cause the pancreas to become enlarged.
Choice B reason: Hyperglycemia and hyper ketonuria are characteristic findings in type 1 diabetes. Hyperglycemia, or high blood sugar, occurs due to the lack of insulin. Hyper ketonuria, or high levels of ketones in the urine, occurs because the body breaks down fats for energy in the absence of insulin, leading to the production of ketones.
Choice C reason: A combination of environmental and genetic factors is considered to be the cause of type 1 diabetes. Genetic predisposition and environmental triggers such as viral infections can lead to the development of the disease.
Choice D reason: Type 1 diabetes most commonly occurs in children and adolescents, with a peak occurrence between the ages of 7 and 15 years. This age range is when the majority of cases are diagnosed.

Correct Answer is D
Explanation
Choice A reason: The neck is the most common site where individuals with Hodgkin Lymphoma (HL) present with nontender enlarged lymph nodes. These lymph nodes are typically firm and rubbery in texture. The cervical lymph nodes are often affected first in HL, making the neck a primary area of concern for this type of lymphoma. Early detection and biopsy of these lymph nodes can help in diagnosing HL.
Choice B reason: While the abdomen can be involved in Hodgkin Lymphoma, it is not the most common initial presentation site. Involvement of the abdominal lymph nodes typically occurs at later stages of the disease. Enlarged lymph nodes in the abdomen can be detected through imaging studies but are less accessible for physical examination compared to those in the neck.
Choice C reason: The kidney is not a typical site for lymph node involvement in Hodgkin Lymphoma. HL primarily affects the lymphatic system, including lymph nodes, spleen, and other lymphoid tissues. Direct involvement of the kidney is rare and usually occurs in advanced stages of the disease.
Choice D reason: The spleen is a lymphoid organ that can be involved in Hodgkin Lymphoma, especially in more advanced stages. However, it is not the primary site where nontender enlarged lymph nodes are first detected. Enlargement of the spleen (splenomegaly) can occur due to the spread of HL, but the initial presentation is usually in the lymph nodes of the neck.
Correct Answer is A
Explanation
Choice A reason: Type 2 diabetes is primarily characterized by insulin resistance, where the body's cells do not respond effectively to insulin. This means that glucose cannot enter the cells efficiently, leading to high blood sugar levels. Additionally, there may be a suboptimal amount of insulin produced by the pancreas. Together, these factors contribute to the development and progression of type 2 diabetes.
Choice B reason: While individuals with type 2 diabetes are at a higher risk for infections due to high blood sugar levels affecting immune function, infection itself is not the root cause of type 2 diabetes. The primary issue in type 2 diabetes is insulin resistance or insufficient insulin production.
Choice C reason: White blood cells (WBC) play a key role in the immune system. Type 2 diabetes does not primarily arise from issues with WBCs. However, high blood sugar levels can impair the function of WBCs, increasing the risk of infections in diabetic individuals.
Choice D reason: Red blood cells (RBC) are responsible for carrying oxygen throughout the body. Type 2 diabetes is not directly related to problems with RBCs. Instead, it is an issue with insulin and blood sugar regulation. While high blood sugar can affect various body functions, the primary problem lies in insulin resistance or insufficient insulin production.
