PREP U ch 51 Caring for Clients with Diabetes Mellitus

Which clinical manifestation of type 2 diabetes occurs if glucose levels are very high?

Blurred vision Blurred vision occurs when blood glucose levels are very high. The other clinical manifestations are not consistent with type 2 diabetes.

A client's blood glucose level is 45 mg/dl. The nurse should be alert for which signs and symptoms?

Coma, anxiety, confusion, headache, and cool, moist skin

A nurse is preparing a client with type 1 diabetes for discharge. The client can care for himself; however, he's had a problem with unstable blood glucose levels in the past. Based on the client's history, he should be referred to which health care worker?

Dietitian

Which combination of adverse effects should a nurse monitor for when administering IV insulin to a client with diabetic ketoacidosis?

Hypokalemia and hypoglycemia

NPH is an example of which type of insulin?

Intermediate-acting NPH is an intermediate-acting insulin.

A school nurse is teaching a group of high school students about risk factors for diabetes. What action has the greatest potential to reduce an individual's risk for developing diabetes?

Lose weight, if obese

The nurse is preparing to administer intermediate-acting insulin to a patient with diabetes. Which insulin will the nurse administer?

NPH

A client tells the nurse that she has been working hard for the past 3 months to control her type 2 diabetes with diet and exercise. To determine the effectiveness of the client's efforts, the nurse should check:

glycosylated hemoglobin level.

A client has been recently diagnosed with type 2 diabetes, and reports continued weight loss despite increased hunger and food consumption. This condition is called:

polyphagia. While the needed glucose is being wasted, the body's requirement for fuel continues. The person with diabetes feels hungry and eats more (polyphagia). Despite eating more, he or she loses weight as the body uses fat and protein to substitute for glucose.

A client newly diagnosed with diabetes mellitus asks why he needs ketone testing when the disease affects his blood glucose levels. How should the nurse respond?

"Ketones will tell us if your body is using other tissues for energy."

The nurse expects that a type 1 diabetic patient may receive what percentage of his or her usual morning dose of insulin preoperatively?

50% to 60%

A 60-year-old client comes to the ED reporting weakness, vision problems, increased thirst, increased urination, and frequent infections that do not seem to heal easily. The physician suspects that the client has diabetes. Which classic symptom should the nurse watch for to confirm the diagnosis of diabetes?

Increased hunger

A client is taking glyburide (DiaBeta), 1.25 mg P.O. daily, to treat type 2 diabetes. Which statement indicates the need for further client teaching about managing this disease?

"I skip lunch when I don't feel hungry." The client requires further teaching if he states that he skips meals. A client who is receiving an oral antidiabetic agent should eat meals on a regular schedule because skipping a meal increases the risk of hypoglycemia. Carrying hard candy, avoiding exposure to the sun, and always wearing a medical identification bracelet indicate effective teaching.

A diabetes educator is teaching a client about type 2 diabetes. The educator recognizes that the client understands the primary treatment for type 2 diabetes when the client states what?

"I will make sure to follow the weight loss plan designed by the dietitian."

A client with diabetes mellitus must learn how to self-administer insulin. The physician has ordered 10 units of U-100 regular insulin and 35 units of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?

"Rotate injection sites within the same anatomic region, not among different regions."

A 16-year-old client newly diagnosed with type 1 diabetes has a very low body weight despite eating regular meals. The client is upset because friends frequently state, "You look anorexic." Which statement by the nurse would be the best response to help this client understand the cause of weight loss due to this condition?

"Your body is using protein and fat for energy instead of glucose." Persons with type 1 diabetes, particularly those in poor control of the condition, tend to be thin because when the body cannot effectively utilize glucose for energy (no insulin supply), it begins to break down protein and fat as an alternate energy source. Patients may be underweight at the onset of type 1 diabetes because of rapid weight loss from severe hyperglycemia. The goal initially may be to provide a higher-calorie diet to regain lost weight and blood glucose control.

A nurse is caring for a client with type 1 diabetes who exhibits confusion, light-headedness, and aberrant behavior. The client is conscious. The nurse should first administer:

15 to 20 g of a fast-acting carbohydrate such as orange juice. This client is experiencing hypoglycemia. Because the client is conscious, the nurse should first administer a fast-acting carbohydrate, such as orange juice, hard candy, or honey. If the client has lost consciousness, the nurse should administer I.M. or subcutaneous glucagon or an I.V. bolus of dextrose 50%. The nurse shouldn't administer insulin to a client who's hypoglycemic; this action will further compromise the client's condition.

A client is admitted with hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Which laboratory finding should the nurse expect in this client?

Blood glucose level 1,100 mg/dl HHNS occurs most frequently in older clients. It can occur in clients with either type 1 or type 2 diabetes mellitus but occurs most commonly in those with type 2. The blood glucose level rises to above 600 mg/dl in response to illness or infection. As the blood glucose level rises, the body attempts to rid itself of the excess glucose by producing urine. Initially, the client produces large quantities of urine. If fluid intake isn't increased at this time, the client becomes dehydrated, causing BUN levels to rise. Arterial pH and plasma bicarbonate levels typically remain within normal limits.

Laboratory studies indicate a client's blood glucose level is 185 mg/dl. Two hours have passed since the client ate breakfast. Which test would yield the most conclusive diagnostic information about the client's glucose use?

Serum glycosylated hemoglobin (Hb A1c) Hb A1c is the most reliable indicator of glucose use because it reflects blood glucose levels for the prior 3 months. Although a fasting blood glucose test and a 6-hour glucose tolerance test yield information about a client's use of glucose, the results are influenced by such factors as whether the client recently ate breakfast. Presence of ketones in the urine also provides information about glucose use but is limited in its diagnostic significance.

A client with type 1 diabetes has a highly elevated glycosylated hemoglobin (Hb) test result. In discussing the result with the client, the nurse is most accurate in stating:

"It tells us about your sugar control for the last 3 months." The nurse is providing accurate information to the client when she states that the glycosylated Hb test provides an objective measure of glycemic control over a 3-month period. The test helps identify trends or practices that impair glycemic control, and it doesn't require a fasting period before blood is drawn. The nurse can't conclude that the result occurs from poor dietary management or inadequate insulin coverage.

Which clinical characteristic is associated with type 2 diabetes (previously referred to as non-insulin-dependent diabetes mellitus)?

Blood glucose can be controlled through diet and exercise Oral hypoglycemic agents may improve blood glucose concentrations if dietary modification and exercise are unsuccessful. Individuals with type 2 diabetes are usually obese at diagnosis. Individuals with type 2 diabetes rarely demonstrate ketosis, except with stress or infection. Individuals with type 2 diabetes do not demonstrate islet cell antibodies.

A 15-year-old child is brought to the emergency department with symptoms of hyperglycemia. Based on the fact that the child's pancreatic beta cells are being destroyed, the client would be diagnosed with what type of diabetes?

Type 1 diabetes

Which may be a potential cause of hypoglycemia in the client diagnosed with diabetes mellitus?

The client has not eaten but continues to take insulin or oral antidiabetic medications. Hypoglycemia occurs when a client with diabetes is not eating and continues to take insulin or oral antidiabetic medications. Hypoglycemia does not occur when the client has not been compliant with the prescribed treatment regimen. If the client has eaten and has not taken or received insulin, diabetic ketoacidosis is more likely to develop.

A client with diabetes mellitus has a blood glucose level of 40 mg/dL. Which rapidly absorbed carbohydrate would be most effective?

1/2 cup fruit juice or regular soft drink In a client with hypoglycemia, the nurse uses the rule of 15: give 15 g of rapidly absorbed carbohydrate, wait 15 minutes, recheck the blood sugar, and administer another 15 g of glucose if the blood sugar is not above 70 mg/dL. One-half cup fruit juice or regular soft drink is equivalent to the recommended 15 g of rapidly absorbed carbohydrate. Eight ounces of skim milk is equivalent to the recommended 15 g of rapidly absorbed carbohydrate. One tablespoon of honey or syrup is equivalent to the recommended 15 g of rapidly absorbed carbohydrate. Six to eight LifeSavers candies is equivalent to the recommended 15 g of rapidly absorbed carbohydrate.
