Answers and Explanations
1. A: Type 1 diabetes is a primary failure of pancreatic beta cells to produce insulin. It primarily affects children and young adults and is unrelated to diet.
2. C: Type 2 diabetes accounts for the overwhelming majority of cases diagnosed in adults. It develops gradually, beginning with insulin resistance and as the requirement for insulin increases, the pancreas becomes progressively less able to produce it.
3. C: Additional risk factors for type 2 diabetes are a family history of diabetes, impaired glucose metabolism, history of gestational diabetes, and race/ethnicity. African-Americans, Hispanics/Latinos, Asian Americans, Native Hawaiians, Pacific Islanders, and Native Americans are at greater risk of developing diabetes than whites.
4. B: African-American, Hispanic/Latina and Native American women are at greater risk of developing gestational diabetes than are white women. Women who experience gestational diabetes are at increased risk of developing diabetes during the decade following pregnancy.
5. D: Untreated diabetes also may result in loss of lower limbs to amputation and death.
6. D: Persons with elevated glucose levels that do not yet meet the criteria for diabetes are considered to have prediabetes and are at increased risk of developing type 2 diabetes. Weight loss and increasing physical activity can help people with prediabetes prevent or postpone the onset of type 2 diabetes.
7. A: Diabetics who smoke are at greater risk of developing heart disease because both diabetes and smoking act to narrow blood vessels. Smoking also is associated with increased risk of eye problems and may compromise circulation to the legs.
8. A: A1c measures the percentage of hemoglobin that is glycated and determines average blood glucose during the two to three months prior to testing. Used as a diagnostic tool, A1C levels of 6.5% or higher on two tests indicate diabetes. A1C of 6% to 6.5% is considered prediabetes.
9. B: Diabetes insipidus is a condition in which the kidneys are unable to conserve water, often because there is insufficient antidiuretic hormone (ADH) or the kidneys are unable to respond to ADH. Although diabetes mellitus may present with similar symptoms, the disorders are different. Diabetes insipidus does not involve hyperglycemia.
10. C: The signs and symptoms that suggest type 1 diabetes include excessive thirst, hunger, urination, weight loss, fatigue, irritability, blurred vision, and infection with candida albicans (also known as yeast infections).
11. B: Excessively high blood sugar or prolonged hyperglycemia can cause diabetic ketoacidosis, the condition in which the body breaks down fat for energy and ketones spill into the urine. Diabetic hyperosmolar syndrome occurs when blood sugar is excessively high and available insulin is ineffective. In this case, the body cannot use glucose or fat for energy and glucose is excreted in the urine. Without immediate medical attention, both conditions may result in coma or death.
12. D: Hyperinsulinemia indicates a difficulty in blood sugar regulation; the pancreas is working to produce enough insulin to regulate blood sugar. Hyperinsulinemia may be cause by a tumor of insulin-producing cells (an insulinoma), excessive numbers of insulin producing cells (nesidioblastosis), or insulin resistance.
13. A: The prevalence of diabetes is increasing dramatically. The CDC reports an increase of more than three million cases in the two years from 2006 to 2008. By 2008, an estimated 8% of the U.S. population had diabetes.
14. B: The CDC reports that adults in the U.S. are at high risk of developing diabetes. Females are at higher risk than males and Hispanics/Latinos are at the greatest risk.
15. C: There is no evidence that eliminating all sugar from the diet benefits people with diabetes. It is more important for diabetics to manage and control total carbohydrate intake so that their blood glucose levels remain on target. Controlling blood glucose, blood pressure, and blood lipid levels can aid in the prevention of complications associated with diabetes.
16. D: Scatter laser treatment is used to shrink abnormal blood vessels in an effort to preserve vision. When there is significant bleeding in the eye, it is removed in a procedure known as vitrectomy. Tonometry is a diagnostic test that measures pressure inside the eye. A fluorescein angiogram is a diagnostic test that traces the flow of dye through the blood vessels in the retina; it is used to detect macular edema.
17. C: Biguanides, such as metformin, lower blood glucose by reducing the amount of glucose produced by the liver. Sulfonylureas and Meglitinides stimulate the beta cells of the pancreas to produce more insulin. Alpha-glucosidase inhibitors block the breakdown of starches and some sugars, which helps to reduce blood glucose levels
18. D: Using an insulin pump has many advantages, including fewer dramatic swings in blood glucose levels, increased flexibility about diet, and improved accuracy of insulin doses and delivery; however, the use of an insulin pump has been associated with weight gain.
19. D: Because persons with type 1 diabetes do not produce insulin, they require insulin and cannot be treated with oral anti-diabetic drugs. Several injections of insulin per day, calibrated to respond to measured blood glucose levels, offer the best blood glucose control and may prevent or postpone the retinal, renal, and neurological complications of diabetes.
20. D: Nerve conduction studies assess transmission of electrical signals through nerves and electromyography evaluates nerve transmission to muscles. Ultrasound can assess the responsivity and function of internal organs that may be compromised by neurological damage. Foot exams help to assess peripheral neuropathy and to ensure the integrity of skin. The MMPI is a psychological test and is not used to assess diabetic neuropathy.
