62
A program of weight loss and exercise is recommended for a patient with insulin resistance syndrome. When the patient asks why these measures are necessary when she really does not have diabetes, what should the nurse explain?
a. The high insulin levels associated with this syndrome damage the lining of blood vessels and cause osmotic diuresis.
b. Although her fasting plasma glucose levels do not indicate diabetes, she has impaired glucose tolerance, which is characteristic of the syndrome.
c. The liver is inappropriately producing glucose, which will eventually exhaust the ability of the pancreas to produce insulin, and exercise will normalize glucose production.
d. She has a variety of abnormalities associated with diabetes, which indicate a very high risk for cardiovascular disease, and the onset of diabetes can be delayed or prevented by weight loss and exercise.
ANS: D
The patient with impaired fasting glucose is at risk for developing type 2 diabetes, but this risk can be decreased with lifestyle changes.
63
When assessing the patient experiencing the onset of type 1 diabetes, which question should the nurse ask?
a. “Have you lost any weight lately?”
b. “Do you crave fluids containing sugar?”
c. “How long have you felt anorexic?”
d. “Is your urine unusually dark-coloured?”
ANS: A
Weight loss occurs because the body is no longer able to absorb glucose and starts to break down protein and fat for energy.
64
During a clinic visit 3 months following a diagnosis of type 2 diabetes, the patient reports that she has been following her reduced-calorie diet, but she has not lost any weight, and she has neglected to bring her record of glucose monitoring results.

Patients using intensive insulin therapy must check their glucose level four to six times daily and administer insulin accordingly.
73
When intensive insulin therapy is used for control of diabetes, the nurse recognizes that which of the following types of insulin is preferred for mealtime coverage?
a. NPH insulin
b. Lispro insulin
c. Lente insulin
d. Insulin glargine
ANS: B
| Rapid- or short-acting insulin is used for mealtime coverage for patients receiving intensive insulin therapy.
74
Glyburide (Diabeta) is prescribed for a patient when her type 2 diabetes has not been controlled with diet and exercise. When teaching the patient about glyburide, what should the nurse explain?
a. Glyburide is thought to stimulate insulin production and release from the pancreas.
b. Glyburide is a substitute for insulin and acts by directly stimulating glucose uptake into the cell.
c. Glyburide, like all oral antidiabetes agents, does not cause the hypoglycemic reactions that may occur with insulin use.
d. Glyburide and other sulphonylureas lower blood sugar by decreasing the rate of hepatic glucose production, preventing gluconeogenesis.
ANS: A
| The sulphonylureas stimulate the production and release of insulin from the pancreas.
75
When teaching a patient with type 2 diabetes about taking an oral antihyperglycemic medication, the nurse determines that additional teaching about the medication is needed when the patient gives which of the following responses?
a. “If I overeat at a meal, I should not take an extra dose of my medication.”
b. “If I become ill or especially stressed, I may have to take insulin to control my blood sugar.”
c. “Given that I can take oral drugs rather than insulin, my diabetes is not serious and won’t cause many complications.”
d. “I should check with my doctor before taking any other medications because there are many that will affect glucose levels.”
ANS: C
The patient should understand that type 2 diabetes places the patient at risk for many complications and that good glucose control is as important when taking oral agents, as when using insulin.

86
A patient recovering from diabetic ketoacidosis asks the nurse how acidosis occurs. What is the best response?
a. Excess glucose in the blood is metabolized by the liver into acetone, which is acidic in nature.
b. An insulin deficit promotes metabolism of fat stores, which produces large amounts of acidic ketones.
c. Insufficient insulin leads to cellular starvation, and as cells rupture, they release organic acids into the blood.
d. When an insulin deficit causes hyperglycemia, then proteins are deaminated by the liver, causing acidic by-products.
ANS: B
| Ketoacidosis is caused by the breakdown of fat stores when glucose is not available for intracellular metabolism.
