Place the phases of the autoimmune reaction in the order in which it occurs. 1. Glucose is unable to enter the cells 2. The individual develops hyperglycemia 3. Beta cells are destroyed by islet cell autoantibodies 4. The individual experiences an altered metabolism of protein, fat, and carbohydrates 5. The body is unable to produce insulin
3, 5, 1, 2, 4 Islet cell autoantibodies destroy beta cells. This creates a reduction of 80%-90% of normal pancreatic functioning. The destroyed beta cells result in a lack of insulin. The lack of insulin means no glucose enters the cells. Without glucose entering the cells, the individual develops hyperglycemia. Once hyperglycemia sets in, there is altered metabolism of protein, fat, and carbohydrates.

Which is an accurate description of insulin resistance? A. Insulin is made by the body B. Insulin is added to the body from an external source C. Cellular insulin receptors have a decreased sensitivity D. Amounts of insulin are insufficient for the body's needs
C. Cellular insulin receptors have a decreased sensitivity This describes insulin resistance. Insulin resistance is when the cells of the body do not react appropriately to the insulin that is present, and it takes more insulin to get the glucose into the cells.
Which is accurate regarding the clinical manifestation of increased hunger in a person with type 1 diabetes? A. Increased hunger is a direct result of increased thirst B. Increased hunger is due to the osmotic pressure of glucose on the filtrate C. Increased hunger is a result of the cells in the body being unable to use glucose D. Increased hunger is due to immune system impairment caused by glucose in the blood
C. Increased hunger is a result of the cells in the body being unable to use glucose The cells in the body are starved of nutrients when a person has diabetes, which makes the cells hungry and stimulates the individual's appetite. Increased appetite is known as polyphagia.
Which degenerative condition is associated with impaired sensation in the form of numbness and tingling in the legs and feet in a person with diabetes? A. Microangiopathy B. Macroangiopathy C. Peripheral neuropathy D. Autonomic neuropathy
C. Peripheral neuropathy Peripheral neuropathy results in impaired sensation such as numbness and tingling, burning pain, or reduced perception of pain.
Which is a clinical manifestation of type 2 diabetes? A. Weight loss B. Hearing changes C. Recurrent yeast infections D. Negative for blood glucose
C. Recurrent yeast infections Recurrent infections, particularly yeast infections, is a clinical manifestation of type 2 diabetes because the excess glucose in the blood reduces the body's immunity and makes it a good breeding ground for yeast.
Which is the rationale for the lack of ketones in the urine of a person with hyperosmotic hyperglycemic nonketotic state (HHNS)? A. Neurologic complications affect the kidneys B. Blood flow decreases and depresses the nervous system C. The body still produces enough insulin to stop lipids from breaking down D. Fats and proteins are catabolized as a result of insufficient glucose in the cells
C. The body still produces enough insulin to stop lipids from breaking down A person with HHNS would test negative for serum and urine ketones. This is because the body produces just enough endogenous (self-made) insulin to prevent the breakdown of lipids and fats.
Which statement is accurate regarding the difference between type 1 and type 2 diabetes? A. Type 1 diabetes can be prevented, and type 2 cannot B. Type 1 diabetes is more prevalent than type 2 diabetes C. Type 1 diabetes is a more severe form of the disease than type 2 D. Type 1 diabetes is more likely to develop later in life than type 2
C. Type 1 diabetes is a more severe form of the disease than type 2 Type 1 diabetes is more severe than type 2 diabetes, because with type 1 diabetes, the body does not produce any insulin, which is required for regulating blood glucose. Type 2 diabetes produces some insulin.
