An agitated, confused client arrives in the emergency department. The client's history includes type 1 diabetes, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting:

10 to 15 g of a simple carbohydrate

A nurse is teaching a client with type 1 diabetes how to treat adverse reactions to insulin. To reverse hypoglycemia, the client ideally should ingest an oral carbohydrate. However, this treatment isn't always possible or safe. Therefore, the nurse should advise the client to keep which alternate treatment on hand?

Glucagon

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

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 ability for glucose to get into the cell and lowers blood sugar

A client with diabetes is receiving an oral anti diabetic agent that acts to help the tissues use available insulin more efficiently. Which of the following agents would the nurse expect to administer? Metformin Glyburide Repaglinide Glipizide

Metformin

A patient who is diagnosed with type 1 diabetes would be expected to:

Need exogenous insulin. Explanation: Type 1 diabetes is characterized by the destruction of pancreatic beta cells that require exogenous insulin.

Lispro (Humalog) is an example of which type of insulin?

Rapid-acting

A nurse is preparing to administer two types of insulin to a client with diabetes mellitus. What is the correct procedure for preparing this medication?

The short-acting insulin is withdrawn before the intermediate-acting insulin.

Which information should be included in the teaching plan for a client receiving glargine, which is "peakless" basal insulin?

Do not mix with other insulins. Explanation: Because glargine is in a suspension with a pH of 4, it cannot be mixed with other insulins because this would cause precipitation. Glargine is a "peakless" basal insulin that is absorbed very slowly over a 24-hour period and can be given once a day. When administering glargine insulin it is very important to read the label carefully and to avoid mistaking Lantus insulin for Lente insulin and vice versa.

A patient is diagnosed with type 1 diabetes. What clinical characteristics does the nurse expect to see in this patient? Select all that apply. Ketosis-prone Little or no endogenous insulin Obesity at diagnoses Younger than 30 years of age Older than 65 years of age

Ketosis-prone Little or no endogenous insulin Younger than 30 years of age

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

Which clinical characteristic is associated with type 1 diabetes (previously referred to as insulin-dependent diabetes mellitus)?

Presence of islet cell antibodies

What is the only insulin that can be given intravenously?

Regular

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

Insulin is a hormone secreted by the Islets of Langerhans and is essential for the metabolism of carbohydrates, fats, and protein. The nurse understands the physiologic importance of gluconeogenesis, which refers to the:

Synthesis of glucose from noncarbohydrate sources.

Which statement indicates that a client with diabetes mellitus understands proper foot care? "I'll schedule an appointment with my physician if my feet start to ache." "I'll rotate insulin injection sites from my left foot to my right foot." "I'll go barefoot around the house to avoid pressure areas on my feet." "I'll wear cotton socks with well-fitting shoes."

"I'll wear cotton socks with well-fitting shoes."

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.

Serum fructosamine levels provide information about blood glucose control over

the past 2 to 3 weeks.

Fasting blood glucose and urine glucose levels give information only about glucose levels at

the point in time when they were obtained.

Which instruction about insulin administration should a nurse give to a client? "Always follow the same order when drawing the different insulins into the syringe." "Shake the vials before withdrawing the insulin." "Store unopened vials of insulin in the freezer at temperatures well below freezing." "Discard the intermediate-acting insulin if it appears cloudy."

"Always follow the same order when drawing the different insulins into the syringe."

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.

After teaching a client with type 1 diabetes who is scheduled to undergo an islet cell transplant, which client statement indicates successful teaching? "This transplant will provide me with a cure for my diabetes." "I will receive a whole organ with extra cells to produce insulin." "They'll need to create a connection from the pancreas to allow enzymes to drain." "I might need insulin later on but probably not as much or as often."

"I might need insulin later on but probably not as much or as often." Explanation: Transplanted islet cells tend to lose their ability to function over time, and approximately 70% of recipients resume insulin administration in 2 years. However, the amount of insulin and the frequency of its administration are reduced because of improved control of blood glucose levels. Thus, this type of transplant doesn't cure diabetes. It requires the use of two human pancreases to obtain sufficient numbers of islet cells for transplantation. A whole organ transplant requires a means for exocrine enzyme drainage and venous absorption of insulin.

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 Kussmaul respirations, dry skin, hypotension, and bradycardia Polyuria, polydipsia, hypotension, and hypernatremia Polyuria, polydipsia, polyphagia, and weight loss

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

A health care provider prescribes short-acting insulin for a patient, instructing the patient to take the insulin 20 to 30 minutes before a meal. The nurse explains to the patient that Humulin-R taken at 6:30 AM will reach peak effectiveness by:

8:30 a.m. Explanation: Short-acting insulin reaches its peak effectiveness 2 to 3 hours after administration. See Table 30-3 in the text.

Which assessment finding is most important in determining nursing care for a client with diabetes mellitus? Respirations of 12 breaths/minute Cloudy urine Blood sugar 170 mg/dL Fruity breath

Fruity breath

When administering insulin to a client with type 1 diabetes, which of the following would be most important for the nurse to keep in mind?

Accuracy of the dosage

A nurse is caring for a diabetic patient with a diagnosis of nephropathy. What would the nurse expect the urinalysis report to indicate?

Albumin Explanation: Nephropathy, or kidney disease secondary to diabetic microvascular changes in the kidney, is a common complication of diabetes. Consistent elevation of blood glucose levels stresses the kidney's filtration mechanism, allowing blood proteins to leak into the urine and thus increasing the pressure in the blood vessels of the kidney. Albumin is one of the most important blood proteins that leak into the urine, and its leakage is among the earliest signs that can be detected. Clinical nephropathy eventually develops in more than 85% of people with microalbuminuria but in fewer than 5% of people without microalbuminuria. The urine should be checked annually for the presence of proteins, which would include microalbumin.

A client with a serum glucose level of 618 mg/dl is admitted to the facility. He's awake and oriented, has hot dry skin, and has the following vital signs: temperature of 100.6° F (38.1° C), heart rate of 116 beats/minute, and blood pressure of 108/70 mm Hg. Based on these assessment findings, which nursing diagnosis takes highest priority? Deficient fluid volume related to osmotic diuresis Decreased cardiac output related to elevated heart rate Imbalanced nutrition: Less than body requirements related to insulin deficiency Ineffective thermoregulation related to dehydration

Deficient fluid volume related to osmotic diuresis

The nurse instructs the client with diabetes on self-care during days of illness. Which client statement indicates that teaching has been effective? Select all that apply. "I will increase my intake of fluids." "I will skip my diabetes medication for the day." "I will test my blood sugar level every 3 to 4 hours." "I will call the doctor if I have vomiting or diarrhea." "I will eat soft foods if I cannot tolerate regular food."

"I will increase my intake of fluids." "I will test my blood sugar level every 3 to 4 hours." "I will call the doctor if I have vomiting or diarrhea." "I will eat soft foods if I cannot tolerate regular food."

A nurse is preparing a continuous insulin infusion for a child with diabetic ketoacidosis and a blood glucose level of 800 mg/dl. Which solution is the most appropriate at the beginning of therapy? 100 units of regular insulin in normal saline solution 100 units of neutral protamine Hagedorn (NPH) insulin in normal saline solution 100 units of regular insulin in dextrose 5% in water 100 units of NPH insulin in dextrose 5% in water

100 units of regular insulin in normal saline solution

A client with diabetes comes to the clinic for a follow-up visit. The nurse reviews the client's glycosylated hemoglobin test results. Which result would indicate to the nurse that the client's blood glucose level has been well controlled?

6.5%

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

Hypokalemia and hypoglycemia Explanation: Blood glucose needs to be monitored in clients receiving IV insulin because of the risk of hyperglycemia or hypoglycemia. Hypoglycemia might occur if too much insulin is administered. Hypokalemia, not hyperkalemia, might occur because I.V. insulin forces potassium into cells, thereby lowering the plasma level of potassium. Calcium and sodium levels aren't affected by IV insulin administration.

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

A young adult client with type 1 diabetes does not want to have to self-administer insulin injections several times a day. Which medication approach would the nurse recommend that best controls the condition and meets the client's needs? Insulin pump 1 injection per day 2 injections premixed Injection before each meal

Insulin pump Explanation: The insulin pump most closely mimics regular pancreas function and increases meal and exercise flexibility. The use of the pump would meet the client's needs of not wanting to self-administer several injections of insulin every day. With one injection per day, there is difficulty controlling fasting blood glucose if the type of insulin does not last. The client could also develop afternoon hypoglycemia if the single dose is increased in order to control the morning fasting glucose level. Two injections per day might meet the client's needs of minimal self-injections; however, for this regimen, there needs to be a fixed schedule of meals and exercise and it is difficult to adjust the dose if premixed insulin is used. Self-administering insulin before each meal will not meet the client's needs since this requires more injections than any other regimen.

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

NPH

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 Explanation: 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.

A client who was diagnosed with type 1 diabetes 14 years ago is admitted to the medical-surgical unit with abdominal pain. On admission, the client's blood glucose level is 470 mg/dl. Which finding is most likely to accompany this blood glucose level? Cool, moist skin Rapid, thready pulse Arm and leg trembling Slow, shallow respirations

Rapid, thready pulse Explanation: This client's abnormally high blood glucose level indicates hyperglycemia, which typically causes polyuria, polyphagia, and polydipsia. Because polyuria leads to fluid loss, the nurse should expect to assess signs of deficient fluid volume, such as a rapid, thready pulse; decreased blood pressure; and rapid respirations.

A patient has been newly diagnosed with type 2 diabetes, and the nurse is assisting with the development of a meal plan. What step should be taken into consideration prior to making the meal plan?

Reviewing the patient's diet history to identify eating habits and lifestyle and cultural eating patterns

A client with diabetes mellitus develops sinusitis and otitis media accompanied by a temperature of 100.8° F (38.2° C). What effect do these findings have on his need for insulin?

They increase his need for insulin

A client with type 2 diabetes asks the nurse why he can't have a pancreatic transplant. Which of the following would the nurse include as a possible reason?

Underlying problem of insulin resistance Explanation: Clients with type 2 diabetes are not offered the option of a pancreas transplant because their problem is insulin resistance, which does not improve with a transplant.

During a class on exercise for clients with diabetes mellitus, a client asks the nurse educator how often to exercise. To meet the goals of planned exercise, the nurse educator should advise the client to exercise:

at least three times per week.

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. Explanation: 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.
