Individuals with diabetes, a minor injury to the foot can cause major complications due to:
Increased WBC in the blood.
Edema to the tissues
Increase blood flow by giving more oxygen to the tissues.
Decreased blood flow to the tissues causing gangrene.
The Correct Answer is D
Choice A reason: While white blood cells (WBC) are essential for fighting infections, increased WBCs in the blood is not the reason why a minor injury can cause major complications in individuals with diabetes. In fact, diabetes can impair the function of WBCs, making it harder to fight infections.
Choice B reason: Edema, or swelling, can occur in individuals with diabetes, especially in the lower extremities. However, it is not the primary reason why minor injuries can lead to severe complications. Edema can contribute to discomfort and further complications, but it is not the root cause.
Choice C reason: Increased blood flow and oxygen delivery to tissues would generally be beneficial for healing. However, individuals with diabetes often have impaired blood flow, not increased blood flow. This impairment can hinder the healing process and lead to complications.
Choice D reason: The major reason why a minor injury can cause significant complications in individuals with diabetes is due to decreased blood flow to the tissues. Diabetes can cause damage to blood vessels and nerves (peripheral neuropathy), leading to poor circulation and a reduced ability to sense injuries. This decreased blood flow can prevent adequate delivery of oxygen and nutrients to the tissues, leading to slow healing, increased risk of infection, and in severe cases, gangrene (tissue death). Without proper blood flow, even minor injuries can become serious and may require medical intervention, including possible amputation to prevent the spread of infection.

Correct Answer is D
Explanation
Choice A reason: Increased lipid breakdown does not directly cause the release of insulin. Insulin is a hormone that facilitates glucose uptake by cells and helps regulate blood sugar levels. Lipid metabolism is primarily regulated by other mechanisms and hormones, such as glucagon and epinephrine.
Choice B reason: Decreased blood glucose level would not stimulate insulin release. In fact, low blood glucose levels would signal the pancreas to reduce insulin secretion. Instead, glucagon would be released to increase blood glucose levels by stimulating the conversion of glycogen to glucose in the liver.
Choice C reason: Increased protein breakdown does not directly trigger the release of insulin. Protein metabolism involves amino acids and other metabolic pathways, but insulin release is primarily regulated by blood glucose levels.
Choice D reason: The release of insulin is caused by increased blood glucose levels. When blood glucose levels rise, such as after eating a meal, the beta cells in the pancreas secrete insulin to help cells absorb glucose from the bloodstream, thereby lowering blood glucose levels and maintaining homeostasis.
Correct Answer is A
Explanation
Choice A reason: The primary distinction between ALL and AML is the type of cell that becomes cancerous. Acute Lymphocytic Leukemia (ALL) affects the lymphoid cell line. Lymphoid cells, or lymphocytes, are a type of white blood cell that plays a crucial role in the immune system, helping the body to fight infections. There are three types of lymphocytes: B cells, T cells, and natural killer (NK) cells. In ALL, the malignant transformation of these lymphocytes occurs, leading to an overproduction of immature lymphoid cells, or lymphoblasts. These lymphoblasts crowd out normal blood cells in the bone marrow, leading to symptoms such as anemia, susceptibility to infections, and easy bruising or bleeding.
Choice B reason: While it is true that ALL is more prevalent in children and AML is more common in adults, this age distribution is not the primary distinguishing feature between the two types of leukemia. ALL represents about 75% of pediatric leukemia cases, typically affecting children between 2 and 5 years old, while AML is more commonly diagnosed in adults, with the incidence increasing with age. However, both types can occur at any age, and the age of onset alone is not sufficient to distinguish between them. The differentiation based on cell type remains the most significant factor.
Choice C reason: Clinical manifestations of ALL and AML can be very similar because both involve the proliferation of immature white blood cells in the bone marrow, which disrupts normal blood cell production. Common symptoms include fatigue, frequent infections, fever, weight loss, easy bruising or bleeding, and bone pain. These symptoms result from the overproduction of immature leukemic cells and the subsequent suppression of normal hematopoiesis. Although there may be some differences in presentation based on the specific cell types involved, clinical manifestations are not the primary basis for differentiating between ALL and AML.
Choice D reason: The diagnostic tests used for ALL and AML are quite similar and typically include complete blood counts (CBC), bone marrow biopsy, and flow cytometry to identify the types of cells involved. Cytogenetic and molecular studies are also used to detect specific genetic abnormalities associated with each type of leukemia. While certain markers and genetic mutations may differ between ALL and AML, the overall approach to diagnosis involves similar testing methods. Therefore, the primary difference between the two leukemias lies in the cell type affected rather than the specific diagnostic tests used.
