N403 Ch 51 Diabetes

A nurse is teaching a client recovering from diabetic ketoacidosis (DKA) about management of "sick days." The client asks the nurse why it is important to monitor the urine for ketones. Which statement is the nurse's best response?

"Ketones accumulate in the blood and urine when fat breaks down in the absence of insulin. Ketones signal an insulin deficiency that will cause the body to start breaking down stored fat for energy." Ketones (or ketone bodies) are by-products of fat breakdown in the absence of insulin, and they accumulate in the blood and urine. Ketones in the urine signal an insulin deficiency and that control of type 1 diabetes is deteriorating. When almost no effective insulin is available, the body starts to break down stored fat for energy.

The nurse is administering lispro insulin. Based on the onset of action, how long before breakfast should the nurse administer the injection?

10-15 minutes The onset of action of rapid-acting lispro insulin is within 10 to 15 minutes. It is used to rapidly reduce the glucose level.

The nurse is preparing a presentation for a group of adults at a local community center about diabetes. Which of the following would the nurse include as associated with type 2 diabetes?

15-20g 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.

Which statement is true regarding gestational diabetes?

A Glucose challenge test should be performed between 24-28 weeks A glucose challenge test should be performed between 24 and 48 weeks in women at average risk. It occurs in 2% to 5% of all pregnancies. Onset usually occurs in the second or third trimester. There is an above-normal risk for perinatal complications.

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

Coma, anxiety, headache and cool and moist skin Signs and symptoms of hypoglycemia (indicated by a blood glucose level of 45 mf/dl) include anxiety, restlessness, headache, irritability, confusion, diaphoresis, cool skin, tremors, coma, and seizures. Kussmaul's respirations, dry skin, hypotension, and bradycardia are signs of diabetic ketoacidosis. Excessive thirst, hunger, hypotension, and hypernatremia are symptoms of diabetes insipidus. Polyuria, polydipsia, polyphagia, and weight loss are classic signs and symptoms of diabetes mellitus.

A nurse educates a group of clients with diabetes mellitus on the prevention of diabetic nephropathy. Which of the following suggestions would be most important?

Control blood glucose levels Controlling blood glucose levels and any hypertension can prevent or delay the development of diabetic nephropathy. Drinking plenty of fluids does not prevent diabetic nephropathy. Taking antidiabetic drugs regularly may help to control blood glucose levels, but it is the control of these levels that is most important. A high-fiber diet is unrelated to the development of diabetic nephropathy.

Which of the following would the nurse most likely assess in a client with diabetes who is experiencing autonomic neuropathy?

Erectile dysfunction Autonomic neuropathy affects organ functioning. According the American Diabetes Association, up to 50% of men with diabetes develop erectile dysfunction when nerves that promote erection become impaired. Skeletal deformities and soft tissue ulcers may occur with motor neuropathy. Paresthesias are associated with sensory neuropathy.

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 Because some of the glucose in the bloodstream attaches to some of the hemoglobin and stays attached during the 120-day life span of red blood cells, glycosylated hemoglobin levels provide information about blood glucose levels during the previous 3 months. Fasting blood glucose and urine glucose levels give information only about glucose levels at the point in time when they were obtained. Serum fructosamine levels provide information about blood glucose control over the past 2 to 3 weeks.

A client with diabetes mellitus is receiving an oral antidiabetic agent. The nurse observes for which symptom when caring for this client?

Hypoglycemia The nurse should observe the client receiving an oral antidiabetic agent for signs of hypoglycemia. The time when the reaction might occur is not predictable and could be from 30 to 60 minutes to several hours after the drug is ingested.

The nurse is educating the client with diabetes on setting up a sick plan to manage blood glucose control during times of minor illness such as influenza. Which is the most important teaching item to include?

Increase frequency of glucose self monitoring Minor illnesses such as influenza can present a special challenge to a diabetic client. The body's need for insulin increases during illness. Therefore, the client should take the prescribed insulin dose, increase the frequency of glucose monitoring, and maintain adequate fluid intake to counteract the dehydrating effects of hyperglycemia. Clear liquids and juices are encouraged. Taking less than normal dose of insulin may lead to ketoacidosis.

The client who is managing diabetes through diet and insulin control asks the nurse why exercise is important. Which is the best response by the nurse to support adding exercise to the daily routine?

Increases the ability of glucose to get into the cell and decreases blood sugar Exercise increases trans membrane glucose transporter levels in the skeletal muscles. This allows the glucose to leave the blood and enter into the cells where it can be used as fuel. Exercise can provide an overall feeling of well-being but is not the primary purpose of including in the daily routine of diabetic clients. Exercise does not stimulate the pancreas to produce more cells. Exercise can promote weight loss and decrease risk of insulin resistance but not the primary reason for adding to daily routine.

The nurse is preparing a presentation for a group of adults at a local community center about diabetes. Which of the following would the nurse include as associated with type 2 diabetes?

Insulin production insufficient Type 2 diabetes is characterized by insulin resistance or insufficient insulin production. It is more common in aging adults, and now accounts for 20% of all newly diagnosed cases. Type 1 diabetes is more likely in childhood and adolescence although it can occur at any age. It accounts for approximately 5% to 10% of all diagnosed cases of diabetes. Pre-diabetes can lead to type 2 diabetes.

A client with type 1 diabetes is experiencing polyphagia. The nurse knows to assess for which additional clinical manifestation(s) associated with this classic symptom?

Muscle waisting and tissue loss Polyphagia results from the catabolic state induced by insulin deficiency and the breakdown of proteins and fats. Although clients with type 1 diabetes may experience polyphagia (increased hunger), they may also exhibit muscle wasting, subcutaneous tissue loss, and weight loss due to impaired glucose and protein metabolism and impaired fatty acid storage.

An older adult patient that has type 2 diabetes comes to the emergency department with second-degree burns to the bottom of both feet and states, "I didn't feel too hot but my feet must have been too close to the heater." What does the nurse understand is most likely the reason for the decreasonane in temperature sensation?

Peripheral neuropathy As the neuropathy progresses, the feet become numb. In addition, a decrease in proprioception (awareness of posture and movement of the body and of position and weight of objects in relation to the body) and a decreased sensation of light touch may lead to an unsteady gait. Decreased sensations of pain and temperature place patients with neuropathy at increased risk for injury and undetected foot infections.

A nurse is teaching a diabetic support group about the causes of type 1 diabetes. The teaching is determined to be effective when the group is able to attribute which factor as a cause of type 1 diabetes?

Presence of autoantibodies against islet cells. There is evidence of an autoimmune response in type 1 diabetes. This is an abnormal response in which antibodies are directed against normal tissues of the body, responding to these tissues as if they were foreign. Autoantibodies against islet cells and against endogenous (internal) insulin have been detected in people at the time of diagnosis and even several years before the development of clinical signs of type 1 diabetes.

What is the only insulin that can be given intravenously?

Regular

A client is admitted to the unit with diabetic ketoacidosis (DKA). Which insulin would the nurse expect to administer intravenously?

Regular Regular insulin is administered intravenously to treat DKA. It is added to an IV solution and infused continuously. Glargine, NPH, and Lente are only administered subcutaneously.

A client with status asthmaticus requires endotracheal intubation and mechanical ventilation. Twenty-four hours after intubation, the client is started on the insulin infusion protocol. The nurse must monitor the client's blood glucose levels hourly and watch for which early signs and symptoms associated with hypoglycemia?

Sweating, tremors, and tachycardia Sweating, tremors, and tachycardia, thirst, and anxiety are early signs of hypoglycemia. Dry skin, bradycardia, and somnolence are signs and symptoms associated with hypothyroidism. Polyuria, polydipsia, and polyphagia are signs and symptoms of diabetes mellitus.

The nurse is teaching a client about self-administration of insulin and about mixing regular and neutral protamine Hagedorn (NPH) insulin. Which information is important to include in the teaching plan?

When mixing insulin, the regular insulin is drawn up into the syringe first. When rapid-acting or short-acting insulins are to be given simultaneously with longer-acting insulins, they are usually mixed together in the same syringe; the longer-acting insulins must be mixed thoroughly before being drawn into the syringe. The American Diabetic Association recommends that the regular insulin be drawn up first. The most important issues are that patients (1) are consistent in technique, so the wrong dose is not drawn in error or the wrong type of insulin, and (2) do not inject one type of insulin into the bottle containing a different type of insulin. Injecting cloudy insulin into a vial of clear insulin contaminates the entire vial of clear insulin and alters its action.
