A client diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which statement indicates that the client understands his condition and how to control it? "I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual." "If I experience trembling, weakness, and headache, I should drink a glass of soda that contains sugar." "I will have to monitor my blood glucose level closely and notify the physician if it's constantly elevated." "If I begin to feel especially hungry and thirsty, I'll eat a snack high in carbohydrates."

"I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual." The client stating that he'll remain hydrated and pay attention to his eating, drinking, and voiding needs indicates understanding of HHNS. Inadequate fluid intake during hyperglycemic episodes commonly leads to HHNS. By recognizing the signs of hyperglycemia (polyuria, polydipsia, and polyphagia) and increasing fluid intake, the client may prevent HHNS. Drinking a glass of non-diet soda would be appropriate for hypoglycemia. A client whose diabetes is controlled with oral antidiabetic agents usually doesn't need to monitor blood glucose levels. A high-carbohydrate diet would exacerbate the client's condition, particularly if fluid intake is low.

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." 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 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 always carry hard candy to eat in case my blood sugar level drops." "I avoid exposure to the sun as much as possible." "I always wear my medical identification bracelet." "I skip lunch when I don't feel hungry."

"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 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? "Inject insulin into healthy tissue with large blood vessels and nerves." "Rotate injection sites within the same anatomic region, not among different regions." "Administer insulin into areas of scar tissue or hypertrophy whenever possible." "Administer insulin into sites above muscles that you plan to exercise heavily later that day."

"Rotate injection sites within the same anatomic region, not among different regions." The nurse should instruct the client to rotate injection sites within the same anatomic region. Rotating sites among different regions may cause excessive day-to-day variations in the blood glucose level; also, insulin absorption differs from one region to the next. Insulin should be injected only into healthy tissue lacking large blood vessels, nerves, or scar tissue or other deviations. Injecting insulin into areas of hypertrophy may delay absorption. The client shouldn't inject insulin into areas of lipodystrophy (such as hypertrophy or atrophy); to prevent lipodystrophy, the client should rotate injection sites systematically. Exercise speeds drug absorption, so the client shouldn't inject insulin into sites above muscles that will be exercised heavily.

Which instruction should a nurse give to a client with diabetes mellitus when teaching about "sick day rules"? "Don't take your insulin or oral antidiabetic agent if you don't eat." "It's okay for your blood glucose to go above 300 mg/dl while you're sick." "Test your blood glucose every 4 hours." "Follow your regular meal plan, even if you're nauseous."

"Test your blood glucose every 4 hours." The nurse should instruct a client with diabetes mellitus to check his blood glucose levels every 3 to 4 hours and take insulin or an oral antidiabetic agent as usual, even when he's sick. If the client's blood glucose level rises above 300 mg/dl, he should call his physician immediately. If the client is unable to follow the regular meal plan because of nausea, he should substitute soft foods, such as gelatin, soup, and custard.

A patient who is 6 months' pregnant was evaluated for gestational diabetes mellitus. The doctor considered prescribing insulin based on the serum glucose result of: 90 mg/dL before meals. 120 mg/dL, 1 hour postprandial. 80 mg/dL, 1 hour postprandial. 138 mg/dL, 2 hours postprandial.

138 mg/dL, 2 hours postprandial. The goals for a 2-hour, postprandial blood glucose level are less than 120 mg/dL in a patient who might develop gestational diabetes.

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 Client is usually thin at diagnosis Client is prone to ketosis Clients demonstrate islet cell antibodies

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 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 Signs and symptoms of hypoglycemia (indicated by a blood glucose level of 45 mg/dl) include anxiety, restlessness, headache, irritability, confusion, diaphoresis, cool skin, tremors, coma, and seizures. Kussmaul 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 client with diabetes mellitus is receiving an oral antidiabetic agent. When caring for this client, the nurse should observe for signs of: hypoglycemia polyuria blurred vision polydipsia

hypoglycemia The nurse should observe the client receiving an oral antidiabetic agent for the 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.

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 A serum glucose level of 618 mg/dl indicates hyperglycemia, which causes polyuria and fluid volume deficit, making Deficient fluid volume related to osmotic diuresis the highest priority. In this client, tachycardia is more likely to result from fluid volume deficit than from decreased cardiac output because his blood pressure is normal. Although the client's serum glucose is elevated, food isn't a priority because fluids and insulin should be administered to lower the serum glucose level. Therefore, a diagnosis of Imbalanced nutrition: Less than body requirements isn't appropriate. A temperature of 100.6° F isn't life-threatening, eliminating Ineffective thermoregulation as the top priority.

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? Epinephrine Glucagon 50% dextrose Hydrocortisone

Glucagon During a hypoglycemic reaction, a layperson may administer glucagon, an antihypoglycemic agent, to raise the blood glucose level quickly in a client who can't ingest an oral carbohydrate. Epinephrine isn't a treatment for hypoglycemia. Although 50% dextrose is used to treat hypoglycemia, it must be administered I.V. by a skilled health care professional. Hydrocortisone takes a relatively long time to raise the blood glucose level and therefore isn't effective in reversing hypoglycemia.

A client with diabetes mellitus is receiving an oral antidiabetic agent. The nurse observes for which condition when caring for this client? Polyuria Hypoglycemia Blurred vision Polydipsia

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. Polyuria, polydipsia, and blurred vision are symptoms of diabetes mellitus.

Which combination of adverse effects should a nurse monitor for when administering IV insulin to a client with diabetic ketoacidosis? Hypokalemia and hypoglycemia Hypocalcemia and hyperkalemia Hyperkalemia and hyperglycemia Hypernatremia and hypercalcemia

Hypokalemia and hypoglycemia 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.

A nurse explains to a client that she will administer his first insulin dose in his abdomen. How does absorption at the abdominal site compare with absorption at other sites? Insulin is absorbed more slowly at abdominal injection sites than at other sites. Insulin is absorbed rapidly regardless of the injection site. Insulin is absorbed more rapidly at abdominal injection sites than at other sites. Insulin is absorbed unpredictably at all injection sites.

Insulin is absorbed more rapidly at abdominal injection sites than at other sites. Subcutaneous insulin is absorbed most rapidly at abdominal injection sites, more slowly at sites on the arms, and slowest at sites on the anterior thigh. Absorption after injection in the buttocks is less predictable.

A client with diabetes is receiving an oral antidiabetic 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 Metformin is a biguanide and along with the thiazolidinediones (rosiglitazone and pioglitazone) are categorized as insulin sensitizers; they help tissues use available insulin more efficiently. Glyburide and glipizide which are sulfonylureas, and repaglinide, a meglitinide, are described as being insulin releasers because they stimulate the pancreas to secrete more insulin.

A group of students are reviewing the various types of drugs that are used to treat diabetes mellitus. The students demonstrate understanding of the material when they identify which of the following as an example of an alpha-glucosidase inhibitor? Metformin Glyburide Miglitol Rosiglitazone

Miglitol Alpha-glucosidase inhibitors include drugs such as miglitol and acarbose. Metformin is a biguanide. Glyburide is a sulfonylurea. Rosiglitazone is a thiazolidinedione.

A nurse expects to find which signs and symptoms in a client experiencing hypoglycemia? Polyuria, headache, and fatigue Polyphagia and flushed, dry skin Polydipsia, pallor, and irritability Nervousness, diaphoresis, and confusion

Nervousness, diaphoresis, and confusion Signs and symptoms associated with hypoglycemia include nervousness, diaphoresis, weakness, light-headedness, confusion, paresthesia, irritability, headache, hunger, tachycardia, and changes in speech, hearing, or vision. If untreated, signs and symptoms may progress to unconsciousness, seizures, coma, and death. Polydipsia, polyuria, and polyphagia are symptoms associated with hyperglycemia.

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 Obesity Rare ketosis Altered glucose metabolism

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.

Lispro (Humalog) is an example of which type of insulin? Rapid-acting Intermediate-acting Short-acting Long-acting

Rapid-acting Humalog is a rapid-acting insulin. NPH is an intermediate-acting insulin. A short-acting insulin is Humulin-R. An example of a long-acting insulin is Glargine (Lantus).

A client with diabetes mellitus has a prescription for 5 units of U-100 regular insulin and 25 units of U-100 isophane insulin suspension (NPH) to be taken before breakfast. At about 4:30 p.m., the client experiences headache, sweating, tremor, pallor, and nervousness. What is the most probable cause of these signs and symptoms? Serum glucose level of 450 mg/dl Serum glucose level of 52 mg/dl Serum calcium level of 8.9 mg/dl Serum calcium level of 10.2 mg/dl

Serum glucose level of 52 mg/dl Headache, sweating, tremor, pallor, and nervousness typically result from hypoglycemia, an insulin reaction in which serum glucose level drops below 70 mg/dl. Hypoglycemia may occur 4 to 18 hours after admnistration of isophane insulin suspension or insulin zinc suspension (Lente), which are intermediate-acting insulins. Although hypoglycemia may occur at any time, it usually precedes meals. Hyperglycemia, in which serum glucose level is above 180 mg/dl, causes such early manifestations as fatigue, malaise, drowsiness, polyuria, and polydipsia. A serum calcium level of 8.9 mg/dl or 10.2 mg/dl is within normal range and wouldn't cause the client's symptoms.

After being sick for 3 days, a client with a history of diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should evaluate which diagnostic test results to prevent dysrhythmias? Serum potassium level Serum calcium level Serum sodium level Serum chloride level

Serum potassium level The nurse should monitor the client's potassium level because during periods of acidosis, potassium leaves the cell, causing hyperkalemia. As blood glucose levels normalize with treatment, potassium reenters the cell, causing hypokalemia if levels aren't monitored closely. Hypokalemia places the client at risk for cardiac arrhythmias such as ventricular tachycardia. DKA has a lesser affect on serum calcium, sodium, and chloride levels. Changes in these levels don't typically cause cardiac arrhythmias.

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 Dry skin, bradycardia, and somnolence Bradycardia, thirst, and anxiety Polyuria, polydipsia, and polyphagia

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 pancreas continues to release a small amount of basal insulin overnight, while a person is sleeping. The nurse knows that if the body needs more sugar: The pancreatic hormone glucagon will stimulate the liver to release stored glucose. Insulin will be released to facilitate the transport of sugar. Glycogenesis will be decreased by the liver. The process of gluconeogenesis will be inhibited.

The pancreatic hormone glucagon will stimulate the liver to release stored glucose. When sugar levels are low, glucagon promotes hyperglycemia by stimulating the release of stored glucose. Glycogenolysis and gluconeogenesis will both be increased. Insulin secretion would promote hypoglycemia.

A client receives a daily injection of glargine insulin at 7:00 a.m. When should the nurse monitor this client for a hypoglycemic reaction? Between 8:00 and 10:00 a.m. Between 4:00 and 6:00 p.m. Between 7:00 and 9:00 p.m. This insulin has no peak action and does not cause a hypoglycemic reaction.

This insulin has no peak action and does not cause a hypoglycemic reaction. "Peakless" basal or very long-acting insulins are approved by the U.S. Food and Drug Administration for use as a basal insulin; that is, the insulin is absorbed very slowly over 24 hours and can be given once a day. It has is no peak action.

A client with a history of type 1 diabetes is demonstrating fast, deep, labored breathing and has fruity odored breath. What could be the cause of the client's current serious condition? ketoacidosis hyperosmolar hyperglycemic nonketotic syndrome hepatic disorder All options are correct.

ketoacidosis Kussmaul respirations (fast, deep, labored breathing) are common in ketoacidosis. Acetone, which is volatile, can be detected on the breath by its characteristic fruity odor. If treatment is not initiated, the outcome of ketoacidosis is circulatory collapse, renal shutdown, and death. Ketoacidosis is more common in people with diabetes who no longer produce insulin, such as those with type 1 diabetes. People with type 2 diabetes are more likely to develop hyperosmolar hyperglycemic nonketotic syndrome because with limited insulin, they can use enough glucose to prevent ketosis but not enough to maintain a normal blood glucose level.

A client with type 1 diabetes has been on a regimen of multiple daily injection therapy. He's being converted to continuous subcutaneous insulin therapy via an insulin pump. While teaching the client about continuous subcutaneous insulin therapy, the nurse should tell him that the regimen includes the use of: intermediate- and long-acting insulins. short- and long-acting insulins. rapid-acting insulin only. short- and intermediate-acting insulins.

rapid-acting insulin only. A continuous subcutaneous insulin regimen uses a basal rate and boluses of rapid-acting insulin. Multiple daily injection therapy uses a combination of rapid-acting and intermediate- or long-acting insulins.
