BMI above the 85th percentile for age and sex B. Family history of diabetes in first- or second-degree relative C. Hypertension based on criteria for children D. Any of the above -CORRECT ANSWER-D. Any of the above Insulin is used to treat both types of diabetes. It acts by: A. Increasing beta cell response to low blood glucose levels B. Stimulating hepatic glucose production C. Increasing peripheral glucose uptake by skeletal muscle and fat D. Improving the circulation of free fatty acids -CORRECT ANSWER-C. Increasing peripheral glucose uptake by skeletal muscle and fat Adam has Type 1 diabetes and plays tennis for his university. He exhibits a Knowledge deficit about his insulin and his diagnosis. He should be taught that: A. He should increase his CHO intake during times of exercise B. Each brand of insulin is equal in bioavailability, so buy the least expensive C. Alcohol produces hypoglycemia and can help control his diabetes when taken in small amounts D. If he does not want to learn to give himself injections, he may substitute an oral hypoglycemic to control his diabetes -CORRECT ANSWER-A. He should increase his CHO intake during times of exercise Insulin preparations are divided into categories based on onset, duration, and intensity of action following subcutaneous inject. Which of the following insulin preparations has the shortest onset and duration of action? A. Insulin lispro B. Insulin glulisine C. Insulin glargine D. Insulin detemir -CORRECT ANSWER-B. Insulin glulisine The drug of choice for Type 2 diabetics is metformin. Metformin: A. Decreases glycogenolysis by the liver B. Increases the release of insulin from beta cells C. Increases intestinal uptake of glucose D. Prevents weight gain associated with hyperglycemia -CORRECT ANSWER-A. Decreases glycogenolysis by the liver Before prescribing metformin, the provider should: A. Draw a serum creatinine level to assess renal function B. Try the patient on insulin C. Prescribe a thyroid preparation if the patient needs to lose weight D. All of the above -CORRECT ANSWER-A. Draw a serum creatinine level to assess renal function Sulfonylureas may be added to a treatment regimen for Type 2 diabetics when lifestyle modifications and metformin are insufficient to achieve target glucose levels. Sulfonylureas have been moved to Step 2 therapy because they: A. Increase endogenous insulin secretion B. Have a significant risk for hypoglycemia C. Address the insulin resistance found in Type 2 diabetics D. Improve insulin binding to receptors -CORRECT ANSWER-B. Have a significant risk for hypoglycemia Dipeptidyl peptidase-4 inhibitors (gliptins) act on the incretin system to improve glycemic control. Advantages of these drugs include: A. Better reduction in glucose levels than other classes B. Less weight gain than sulfonylureas C. Low risk for hypoglycemia D. Can be given twice daily -CORRECT ANSWER-C. Low risk for hypoglycemia Control targets for patients with diabetes include: A. HbA1C between 7 and 8 B. Fasting blood glucose levels between 100 and 120 mg/dl C. Blood pressure less than 130/80 mm Hg D. LDL lipids less than 130 mg/dl -CORRECT ANSWER-C. Blood pressure less than 130/80 mm Hg Establishing glycemic targets is the first step in treatment of both types of diabetes. For Type 1 diabetes: A. Tight control/intensive therapy can be given to adults who are willing to test their blood glucose at least twice daily B. Tight control is acceptable for older adults if they are without complications C. Plasma glucose levels are the same for children as adults D. Conventional therapy has a fasting plasma glucose target between 120 and 150 mg/dl -CORRECT ANSWER-D. Conventional therapy has a fasting plasma glucose target between 120 and 150 mg/dl Treatment with insulin for Type 1 diabetics: A. Starts with a total daily dose of 0.2 to 0.4 units per kg of body weight B. Divides the total doses into three injections based on meal size C. Uses a total daily dose of insulin glargine given once daily with no other insulin required D. Is based on the level of blood glucose -CORRECT ANSWER-A. Starts with a total daily dose of 0.2 to 0.4 units per kg of body weight When the total daily insulin dose is split and given twice daily, which of the following rules may be followed? A. Give two-thirds of the total dose in the morning and one-third in the evening. B. Give 0.3 units per kg of premixed 70/30 insulin with one-third in the morning and two-thirds in the evening. C. Give 50% of an insulin glargine dose in the morning and 50% in the evening. D. Give long-acting insulin in the morning and short-acting insulin at bedtime. -CORRECT ANSWER-A. Give two-thirds of the total dose in the morning and one-third in the evening. Studies have shown that control targets that reduce the HbA1C to less than 7% are associated with fewer long-term complications of diabetes. Patients who should have such a target include: A. Those with long-standing diabetes B. Older adults C. Those with no significant cardiovascular disease D. Young children who are early in their disease -CORRECT ANSWER-C. Those with no significant cardiovascular disease
