Diabetes ?'s

The nurse is teaching a teenage client newly diagnosed with type 1diabetes about complications of the disease. The nurse explains that clients with type 1 diabetes can avoid lipoatrophy by: 1. Rotating injection sites. 2. Checking blood sugars at mealtime and bedtime. 3. Using a sliding scale for additional coverage. 4. Administration of insulin via insulin pump.

1 Lipoatrophy is caused by using the same insulin injection site.

The school nurse has noticed an increase in the number of children in the school being diagnosed with type 2 diabetes. Which changes could the nurse implement at school to help reduce students' risk for developing type 2 diabetes? Standard Text: Select all that apply. 1. Increase the amount of daily physical activity. 2. Meet with all parents and explain the risk that is associated with obesity. 3. Test each child's urine monthly. 4. Teach the parents to avoid administering aspirin to their children. 5. Work with the cafeteria to decrease the amount of fat in the foods served.

1 2 5 Increased physical activity will decrease a child's risk of developing type 2 diabetes. Obese children have an increased risk of type 2 diabetes. Working with the parents, the nurse can reduce the obesity in the school. A diet high in fat is associated with type 2 diabetes.

The nurse is teaching the caregiver of a child who is newly diagnosed with type 1 diabetes mellitus how to minimize pain with insulin injections. Which interventions to minimize pain will the nurse include in the teaching? Standard Text: Select all that apply. 1. Do not reuse needles. 2. Remove all bubbles from the syringe before injecting. 3. Have the child flex the muscle during injection. 4. Inject insulin when it is cold. 5. Do not change the direction of the needle during insertion or withdrawal.

1 2 5 Reusing needles leads to more pain on injection. Removing bubbles from the syringe minimizes pain.Keeping the direction of the syringe constant will minimize pain.

The nurse is providing information to a teenager newly diagnosed with diabetes and his parents. The nurse teaches them that the signs of diabetic ketoacidosis (DKA) include: Standard Text: Select all that apply. 1. Change in mental status. 2. Tachycardia. 3. Fruity breath odor. 4. Rapid, shallow respirations. 5. Abdominal pain.

1 3 5 A change in mental state can be associated with DKA.A fruity breath odor is common when the client is in a state of ketoacidosis.Abdominal pain is commonly seen with DKA.

A 12-year-old has been selected to be a cheerleader for her middle school. This child has been recently diagnosed with type 1 diabetes. In teaching this child's mother about care for her child, the nurse wants the mother to understand that with increased physical activity, the child will need: 1. Decreased food intake. 2. Increased doses of insulin. 3. Increased food intake. 4. Decreased doses of insulin.

3 An increase in physical activity requires an increase in caloric intake to prevent hypoglycemia.

A teenager has arrived in the emergency department (ED) with confusion. The physician suspects diabetic ketoacidosis (DKA). A stat serum glucose is done, and the result is 76l5 mg/dL. The nurse expects that this teen has which symptoms? 1. Tachycardia, dehydration, and abdominal pain 2. Sweating, photophobia, and tremors 3. Dry mucous membranes, blurred vision, and weakness 4. Dry skin, shallow rapid breathing, and dehydration

3 Dry mucous membranes, blurred vision, and weakness are seen with hyperglycemia.

The nurse is caring for a child just admitted with diabetic ketoacidosis (DKA). Which of the physician's orders should the nurse question? 1. Neurological checks hourly 2. Insert urinary catheter and measure output hourly. 3. NPH insulin IV at 0.1 units/kg per hour 4. Stat serum electrolytes

3 NPH insulin is never administered IV. A short-acting insulin needs to be ordered.

A patient with type 2 diabetes that is controlled with diet and metformin (Glucophage) also has severe rheumatoid arthritis (RA). During an acute exacerbation of the patient's arthritis, the health care provider prescribes prednisone (Deltasone) to control inflammation. The nurse will anticipate that the patient may a. require administration of insulin while taking prednisone. b. develop acute hypoglycemia during the RA exacerbation. c. have rashes caused by metformin-prednisone interactions. d. need a diet higher in calories while receiving prednisone.

A Rationale: Glucose levels increase when patients are taking CORTICOsteroids, and insulin may be required to control blood glucose. Hypoglycemia is not a complication of RA exacerbation or prednisone use. Rashes are not an adverse effect caused by taking metformin and prednisone simultaneously. The patient is likely to have an increased appetite when taking prednisone, but it will be important to avoid weight gain for the patient with RA.

3.Analyze the following diagnostic findings for your patient with type 2 diabetes. Which result will need further assessment? a.A1C 9% b.BP 126/80 mm Hg c.FBG 130 mg/dL (7.2 mmol/L) d.LDL cholesterol 100 mg/dL (2.6 mmol/L)

A Rationale: Lowering hemoglobin A1C (to less than 7%) reduces microvascular and neuropathic complications. Tighter glycemic control (normal hemoglobin A1C level, less than 6%) may further reduce complications but increases hypoglycemia risk.

Intramuscular glucagon is administered to an unresponsive patient for treatment of hypoglycemia. Which action should the nurse take after the patient regains consciousness? a. Give the patient a snack of cheese and crackers. b. Have the patient drink a glass of orange juice or nonfat milk. c. Administer a continuous infusion of 5% dextrose for 24 hours. d. Assess the patient for symptoms of hyperglycemia.

A Rationale: Rebound hypoglycemia can occur after glucagon administration, but having a meal containing complex carbohydrates plus protein and fat will help prevent hypoglycemia. Orange juice and nonfat milk will elevate blood sugar rapidly, but the cheese and crackers will stabilize blood sugar. Administration of glucose intravenously might be used in patients who were unable to take in nutrition orally. The patient should be assessed for symptoms of hypoglycemia after glucagon administration.

Cardiac monitoring is initiated for a patient in diabetic ketoacidosis (DKA). The nurse recognizes that this measure is important to identify a. electrocardiographic (ECG) changes and dysrhythmias related to hypokalemia. b. fluid overload resulting from aggressive fluid replacement. c. the presence of hypovolemic shock related to osmotic diuresis. d. cardiovascular collapse resulting from the effects of hyperglycemia.

A Rationale: The hypokalemia associated with metabolic acidosis can lead to potentially fatal dysrhythmias such as ventricular tachycardia and ventricular fibrillation, which would be detected with ECG monitoring. Fluid overload, hypovolemia, and cardiovascular collapse are possible complications of DKA, but cardiac monitoring would not detect theses.

A patient with type 1 diabetes has been using self-monitoring of blood glucose (SMBG) as part of diabetes management. During evaluation of the patient's technique of SMBG, the nurse identifies a need for additional teaching when the patient a. chooses a puncture site in the center of the finger pad. b. washes the puncture site using soap and water. c. says the result of 130 mg indicates good blood sugar control. d. hangs the arm down for a minute before puncturing the site.

A Rationale: The patient is taught to choose a puncture site at the side of the finger pad. The other patient actions indicate that teaching has been effective.

While hospitalized and recovering from an episode of diabetic ketoacidosis, the patient calls the nurse and reports feeling anxious, nervous, and sweaty. Based on the patient's report, the nurse should a. obtain a glucose reading using a finger stick. b. administer 1 mg glucagon subcutaneously. c. have the patient eat a candy bar. d. have the patient drink 4 ounces of orange juice.

A Rationale: The patient's clinical manifestations are consistent with hypoglycemia and the initial action should be to check the patient's glucose with a finger stick or order a stat blood glucose. If the glucose is low, the patient should ingest a rapid-acting carbohydrate, such as orange juice. Glucagon might be given if the patient's symptoms become worse or if the patient is unconscious. Candy bars contain fat, which would slow down the absorption of sugar and delay the response to treatment.

When assessing the patient experiencing the onset of symptoms 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-colored?"

A Rationale: Weight loss occurs because the body is no longer able to absorb glucose and starts to break down protein and fat for energy. The patient is thirsty but does not necessarily crave sugar- containing fluids. Increased appetite is a classic symptom of type 1 diabetes. With the classic symptom of polyuria, urine will be very dilute.

A client has recently been diagnosed with Type I diabetes and asks the nurse for help formulating a nutrition plan. Which of the following recommendations would the nurse make to help the client increase calorie consumption to offset absorption problems? a. Eating small meals with two or three snacks may be more helpful in maintaining blood glucose levels than three large meals. b. Eat small meals with two or three snacks throughout the day to keep blood glucose levels steady c. Increase consumption of simple carbohydrates d. Skip meals to help lose weight

A Eating small meals with two or three snacks may be more helpful in maintaining blood glucose levels than three large meals.

After the home health nurse has taught a patient and family about how to use glargine and regular insulin safely, which action by the patient indicates that the teaching has been successful? a. The patient disposes of the open insulin vials after 4 weeks. b. The patient draws up the regular insulin in the syringe and then draws up the glargine. c. The patient stores extra vials of both types of insulin in the freezer until needed. d. The patient's family prefills the syringes weekly and stores them in the refrigerator.

A Rationale: Insulin can be stored at room temperature for 4 weeks. Glargine should not be mixed with other insulins or prefilled and stored. Freezing alters the insulin molecule and should not be done.

A patient using a split mixed-dose insulin regimen asks the nurse about the use of intensive insulin therapy to achieve tighter glucose control. The nurse should teach the patient that a. intensive insulin therapy requires three or more injections a day in addition to an injection of a basal long-acting insulin. b. intensive insulin therapy is indicated only for newly diagnosed type 1 diabetics who have never experienced ketoacidosis. c. studies have shown that intensive insulin therapy is most effective in preventing the macrovascular complications characteristic of type 2 diabetes. d. an insulin pump provides the best glucose control and requires about the same amount of attention as intensive insulin therapy.

A Rationale: Patients using intensive insulin therapy must check their glucose level four to six times daily and administer insulin accordingly. A previous episode of ketoacidosis is not a contraindication for intensive insulin therapy. Intensive insulin therapy is not confined to type 2 diabetics and would prevent microvascular changes as well as macrovascular changes. Intensive insulin therapy and an insulin pump are comparable in glucose control.

Amitriptyline (Elavil) is prescribed for a diabetic patient with peripheral neuropathy who has burning foot pain occurring mostly at night. Which information should the nurse include when teaching the patient about the new medication? a. Amitriptyline will help prevent the transmission of pain impulses to the brain. b. Amitriptyline will improve sleep and make you less aware of nighttime pain. c. Amitriptyline will decrease the depression caused by the pain. d. Amitriptyline will correct some of the blood vessel changes that cause pain.

A Rationale: Tricyclic antidepressants decrease the transmission of pain impulses to the spinal cord and brain. Tricyclics also improve sleep quality and are used for depression, but that is not the major purpose for their use in diabetic neuropathy. The blood vessel changes that contribute to neuropathy are not affected by tricyclics.

When a client learned that the symptoms of diabetes were caused by high levels of blood glucose the client decided to stop eating carbohydrates. In this instance, the nurse would be concerned that the client would develop what complication? a. acidosis b. atherosclerosis c. glycosuria d. retinopathy

A When a client's carbohydrate consumption is inadequate ketones are produced from the breakdown of fat. These ketones lower the pH of the blood, potentially causing acidosis that can lead to a diabetic coma.

8.Which are appropriate therapies for patients with diabetes mellitus (select all that apply)? a.Use of statins to treat dyslipidemia b.Use of diuretics to treat nephropathy c.Use of ACE inhibitors to treat nephropathy d.Use of serotonin agonists to decrease appetite e.Use of laser photocoagulation to treat retinopathy

A C E Rationale: In patients with diabetes who have microalbuminuria or macroalbuminuria, angiotensin-converting enzyme (ACE) inhibitors (e.g., lisinopril [Prinivil, Zestril]) or angiotensin II receptor antagonists (ARBs) (e.g., losartan [Cozaar]) should be used. Both classes of drugs are used to treat hypertension and have been found to delay the progression of nephropathy in patients with diabetes. The statin drugs are the most widely used lipid-lowering agents. Laser photocoagulation therapy is indicated to reduce the risk of vision loss in patients with proliferative retinopathy, in those with macular edema, and in some cases of nonproliferative retinopathy.

5.You are caring for a patient with newly diagnosed type 1 diabetes. What information is essential to include in your patient teaching before discharge from the hospital (select all that apply)? a.Insulin administration b.Elimination of sugar from diet c.Need to reduce physical activity d.Use of a portable blood glucose monitor e.Hypoglycemia prevention, symptoms, and treatment

A D E Rationale: The nurse ensures that the patient understands the proper use of insulin. The nurse teaches the patient how to use the portable blood glucose monitor and how to recognize and treat signs and symptoms of hypoglycemia and hyperglycemia.

A nurse is reviewing the health record of the client Who has HHS. Which of the following data confirms the diagnosis? Select all that apply. A. Evidence of recent myocardial infarction B. BUN 35 mg/dL C. Takes a calcium channel blocker D. Age of 77 years E. No insulin production

A, B, C, D

A nurse is providing discharge teaching to a client who experienced DKA. Which of the following should the nurse include in the teaching? Select all that apply. A. Drink 3 L of fluid daily B. Monitor blood glucose every 4 hrs when ill C. Administer insulin as prescribed when ill D. Notify provider when BG is 200 mg/dL E. Report ketones in the urine after 24 hours of illness

A, B, C, E

A nurse is presenting information to a group of clients about nutrition habits that prevent type 2 diabetes mellitus. Which of the following should the nurse include in the information? Select all that apply. A. Eat less meat and processed foods. B. Decreased intake of saturated fat. C. Increase daily fiber intake. D. Limit saturated fat intake to 15% of daily caloric intake. E. Include omega-3 fatty acid in the diet

A, B, C, E Healthy nutrition should include decreasing consumption of meats and processed foods, which can prevent diabetes and hyperlipidemia. Healthy nutrition should include lowering LDL by decreasing intake of saturated fats. Healthy nutrition should include increasing dietary fiber to control weight gain and decrease the risk of diabetes and hyperlipidemia. Healthy nutrition should include omega-3 fatty acid for secondary prevention of diabetes and heart disease.

The patient is prescribed 30 units regular insulin and 70 units NPH insulin subcutaneously every morning. The nurse will provide which instruction to the patient? A. "Draw up the regular insulin into the syringe first, followed by the cloudy NPH insulin." B. "Mixing insulins will help increase insulin production." C. "Rotate sites at least once weekly." D. "Use a 23- to 25-gauge syringe with a 1-inch needle for maximum absorption."

A. "Draw up the regular insulin into the syringe first, followed by the cloudy NPH insulin."

The nurse teaches a 38-year-old man who was recently diagnosed with type 1 diabetes mellitus about insulin administration. Which statement by the patient requires an intervention by the nurse? A. "I will discard any insulin bottle that is cloudy in appearance." B. "The best injection site for insulin administration is in my abdomen." C. "I can wash the site with soap and water before insulin administration." D. "I may keep my insulin at room temperature (75o F) for up to a month."

A. "I will discard any insulin bottle that is cloudy in appearance." Intermediate-acting insulin and combination premixed insulin will be cloudy in appearance. Routine hygiene such as washing with soap and rinsing with water is adequate for skin preparation for the patient during self-injections. Insulin vials that the patient is currently using may be left at room temperature for up to 4 weeks unless the room temperature is higher than 86° F (30° C) or below freezing (less than 32° F [0° C]). Rotating sites to different anatomic sites is no longer recommended. Patients should rotate the injection within one particular site, such as the abdomen

The nurse is reviewing laboratory results for the clinic patients to be seen today. Which patient meets the diagnostic criteria for diabetes mellitus? A. A 48-year-old woman with a hemoglobin A1C of 8.4% B. A 58-year-old man with a fasting blood glucose of 111 mg/dL C. A 68-year-old woman with a random plasma glucose of 190 mg/dL D. A 78-year-old man with a 2-hour glucose tolerance plasma glucose of 184 mg/dL

A. A 48-year-old woman with a hemoglobin A1C of 8.4% Criteria for a diagnosis of diabetes mellitus include a hemoglobin A1C ≥ 6.5%, fasting plasma glucose level =126 mg/dL, 2-hour plasma glucose level =200 mg/dL during an oral glucose tolerance test, or classic symptoms of hyperglycemia or hyperglycemic crisis with a random plasma glucose =200 mg/dL.

Which information should be included in a teaching plan for patients taking oral hypoglycemic drugs? (Select all that apply.) A. Limit your alcohol consumption. B. Report symptoms of anorexia and fatigue. C. Take your medication only as needed. D. Notify your physician if blood glucose levels rise above the level set for you.

A. Limit your alcohol consumption. B. Report symptoms of anorexia and fatigue. D. Notify your physician if blood glucose levels rise above the level set for you.

Which actions describe the beneficial effects produced by sulfonylurea oral hypoglycemics? (Select all that apply.) A. Stimulate insulin secretion from beta cells B. Increase hepatic glucose production C. Enhance action of insulin in various tissues D. Inhibit breakdown of insulin by liver

A. Stimulate insulin secretion from beta cells B. Enhance action of insulin in various tissues D. Inhibit breakdown of insulin by liver

Which long-acting insulin mimics natural, basal insulin with no peak action and a duration of 24 hours? A. insulin glargine (Lantus) B. insulin glulisine (Apidra) C. regular insulin (Humulin R) D. NPH insulin

A. insulin glargine (Lantus)

The nurse is educating a pregnant client who has gestational diabetes. Which of the following statements should the nurse make to the client? Select all that apply. a. Cakes, candies, cookies, and regular soft drinks should be avoided. b. Gestational diabetes increases the risk that the mother will develop diabetes later in life. c. Gestational diabetes usually resolves after the baby is born. d. Insulin injections may be necessary. e. The baby will likely be born with diabetes f. The mother should strive to gain no more weight during the pregnancy.

ANS: A, B, C, D Gestational diabetes can occur between the 16th and 28th week of pregnancy. If not responsive to diet and exercise, insulin injections may be necessary. Concentrated sugars should be avoided. Weight gain should continue, but not in excessive amounts. Usually, gestational diabetes disappears after the infant is born. However, diabetes can develop 5 to 10 years after the pregnancy.

The nurse is reviewing laboratory reports of a client who has HHS. Which of the following is an expected finding? A. Serum pH 7.2 B. Serum osmolarity 350 mOsm/L C. Serum potassium 3.8 mg/dL D. Serum creatinine 0.8 mg/dL

B

1.Polydipsia and polyuria related to diabetes mellitus are primarily due to a.the release of ketones from cells during fat metabolism. b.fluid shifts resulting from the osmotic effect of hyperglycemia. c.damage to the kidneys from exposure to high levels of glucose. d.changes in RBCs resulting from attachment of excessive glucose to hemoglobin.

B Rationale: The osmotic effect of glucose produces the manifestations of polydipsia and polyuria

A newly diagnosed type 1 diabetic patient likes to run 3 miles several mornings a week. Which teaching will the nurse implement about exercise for this patient? a. "You should not take the morning NPH insulin before you run." b. "Plan to eat breakfast about an hour before your run." c. "Afternoon running is less likely to cause hypoglycemia." d. "You may want to run a little farther if your glucose is very high."

B Rationale: Blood sugar increases after meals, so this will be the best time to exercise. NPH insulin will not peak until mid-afternoon and is safe to take before a morning run. Running can be done in either the morning or afternoon. If the glucose is very elevated, the patient should postpone the run.

A patient with type 1 diabetes who uses glargine (Lantus) and lispro (Humalog) insulin develops a sore throat, cough, and fever. When the patient calls the clinic to report the symptoms and a blood glucose level of 210 mg/dl, the nurse advises the patient to a. use only the lispro insulin until the symptoms of infection are resolved. b. monitor blood glucose every 4 hours and notify the clinic if it continues to rise. c. decrease intake of carbohydrates until glycosylated hemoglobin is less than 7%. d. limit intake to non-calorie-containing liquids until the glucose is within the usual range.

B Rationale: Infection and other stressors increase blood glucose levels and the patient will need to test blood glucose frequently, treat elevations appropriately with insulin, and call the health care provider if glucose levels continue to be elevated. Discontinuing the glargine will contribute to hyperglycemia and may lead to DKA. Decreasing carbohydrate or caloric intake is not appropriate as the patient will need more calories when ill. Glycosylated hemoglobins are not used to test for short-term alterations in blood glucose.

A patient with type 2 diabetes has sensory neuropathy of the feet and legs and peripheral vascular disease evidenced by decreased peripheral pulses and dependent rubor. The nurse teaches the patient that a. the feet should be soaked in warm water on a daily basis. b. flat-soled leather shoes are the best choice to protect the feet from injury. c. heating pads should always be set at a very low temperature. d. over-the-counter (OTC) callus remover may be used to remove callus and prevent pressure.

B Rationale: The patient is taught to avoid high heels and that leather shoes are preferred. The feet should be washed, but not soaked, in warm water daily. Heating pad use should be avoided. Commercial callus and corn removers should be avoided; the patient should see a specialist to treat these problems.

A diabetic patient is started on intensive insulin therapy. The nurse will plan to teach the patient about mealtime coverage using _____ insulin. a. NPH b. lispro c. detemir d. glargine

B Rationale: Rapid or short acting insulin is used for mealtime coverage for patients receiving intensive insulin therapy. NPH, glargine, or detemir will be used as the basal insulin.

A patient with type 2 diabetes is scheduled for an outpatient coronary arteriogram. Which information obtained by the nurse when admitting the patient indicates a need for a change in the patient's regimen? a. The patient's most recent hemoglobin A1C was 6%. b. The patient takes metformin (Glucophage) every morning. c. The patient uses captopril (Capoten) for hypertension. d. The patient's admission blood glucose is 128 mg/dl.

B Rationale: To avoid lactic acidosis, metformin should not be used for 48 hours after IV contrast media are administered. The other patient data indicate that the patient is managing the diabetes appropriately.

A nurse is assessing a client who has DKA and ketones in the urine. Which of the following are expected findings? Select all that apply. A. Weight gain B. Fruity odor or breath C. Abdominal pain D. Kussmaul respirations E. Metabolic acidosis

B, C, D, E

A client asks the nurse why the provider bases his medication regimen on his HbA1C instead of his log of morning fasting blood glucose results. Which of the following is an appropriate response by the nurse? A. HB A1C measures how well insulin is regulating your blood glucose between meals. B. HB A1 C indicates how well your blood glucose has been regulated over the past three months. C. A test of HB A1C is the first test to determine if an individual has diabetes. D. A test of HB A1C determines if the dosage of insulin needs to be adjusted.

B. HB A1C measures the client's BC control over the past 2 to 4 months.

The nurse is teaching a 60-year-old woman with type 2 diabetes mellitus how to prevent diabetic nephropathy. Which statement made by the patient indicates that teaching has been successful? A. "Smokeless tobacco products decrease the risk of kidney damage." B. "I can help control my blood pressure by avoiding foods high in salt." C. "I should have yearly dilated eye examinations by an ophthalmologist." D. "I will avoid hypoglycemia by keeping my blood sugar above 180 mg/dL."

B. "I can help control my blood pressure by avoiding foods high in salt." Diabetic nephropathy is a microvascular complication associated with damage to the small blood vessels that supply the glomeruli of the kidney. Risk factors for the development of diabetic nephropathy include hypertension, genetic predisposition, smoking, and chronic hyperglycemia. Patients with diabetes are screened for nephropathy annually with a measurement of the albumin-to-creatinine ratio in urine; a serum creatinine is also needed.

The nurse instructs a 22-year-old female patient with diabetes mellitus about a healthy eating plan. Which statement made by the patient indicates that teaching was successful? A. "I plan to lose 25 pounds this year by following a high-protein diet." B. "I may have a hypoglycemic reaction if I drink alcohol on an empty stomach." C. "I should include more fiber in my diet than a person who does not have diabetes." D. "If I use an insulin pump, I will not need to limit the amount of saturated fat in my diet."

B. "I may have a hypoglycemic reaction if I drink alcohol on an empty stomach." The risk for alcohol-induced hypoglycemia is reduced by eating carbohydrates when drinking alcohol. Intensified insulin therapy, such as the use of an insulin pump, allows considerable flexibility in food selection and can be adjusted for alterations from usual eating and exercise habits. However, saturated fat intake should still be limited to less than 7% of total daily calories. Daily fiber intake of 14 g/1000 kcal is recommended for the general population and for patients with diabetes mellitus. High-protein diets are not recommended for weight loss.

Which patient with type 1 diabetes mellitus would be at the highest risk for developing hypoglycemic unawareness? A. A 58-year-old patient with diabetic retinopathy B. A 73-year-old patient who takes propranolol (Inderal) C. A 19-year-old patient who is on the school track team D. A 24-year-old patient with a hemoglobin A1C of 8.9%

B. A 73-year-old patient who takes propranolol (Inderal) Hypoglycemic unawareness is a condition in which a person does not experience the warning signs and symptoms of hypoglycemia until the person becomes incoherent and combative or loses consciousness. Hypoglycemic awareness is related to autonomic neuropathy of diabetes that interferes with the secretion of counterregulatory hormones that produce these symptoms. Older patients and patients who use â-adrenergic blockers (e.g., propranolol) are at risk for hypoglycemic unawareness.

Which of the following things must the nurse working with diabetic clients keep in mind about Hyperglycemic Hyperosmolar Nonketotic Syndrome (HHNS)? A. This syndrome occurs mainly in people with Type I Diabetes B. It has a higher mortality rate than Diabetic Ketoacidosis C. The client with HHNS is in a state of overhydration D. This condition develops very rapidly

B. It has a higher mortality rate than Diabetic Ketoacidosis HHNS occurs only in people with Type II Diabetes. It is a medical emergency and has a higher mortality rate than Diabetic Ketoacidosis. This condition develops very slowly over hours or days.

When caring for a patient newly diagnosed with gestational diabetes, the nurse would question an order for which drug? A. insulin glargine (Lantus) B. glipizide (Glucotrol) C. insulin glulisine (Apidra) D. NPH insulin

B. glipizide (Glucotrol)

The nurse will advise the patient to treat hypoglycemia with which drug? A. propranolol (Inderal) B. glucagon C. acarbose (Precose) D. bumetanide (Bumex)

B. glucagon

Which is a rapid-acting insulin with an onset of action of less than 15 minutes? A. insulin glargine (Lantus) B. insulin aspart (NovoLog) C. regular insulin (Humulin R) D. insulin detemir (Levemir)

B. insulin aspart (NovoLog)

A nurse is preparing to administer IV fluids to client who has DKA. Which of the following is an appropriate nursing action? A. Administering IV infusion of regular insulin at 0.3 units per kilogram per hour B. Administer and IV infusion of 0.45% sodium chloride C. Rapidly administering IV infusion of 0.9% sodium chloride D. Add glucose to the IV infusion when serum glucose is 350 mg/dL

C

6.What is the priority action for the nurse to take if the patient with type 2 diabetes complains of blurred vision and irritability? a.Call the physician. b.Administer insulin as ordered. c.Check the patient's blood glucose level. d.Assess for other neurologic symptoms.

C Rationale: Blood glucose testing should be performed whenever hypoglycemia is suspected so that immediate action can be taken if necessary.

7.A diabetic patient has a serum glucose level of 824 mg/dL (45.7 mmol/L) and is unresponsive. After assessing the patient, the nurse suspects diabetic ketoacidosis rather than hyperosmolar hyperglycemic syndrome based on the finding of a.polyuria. b.severe dehydration. c.rapid, deep respirations. d.decreased serum potassium.

C Rationale: Signs and symptoms of DKA include manifestations of dehydration, such as poor skin turgor, dry mucous membranes, tachycardia, and orthostatic hypotension. Early symptoms may include lethargy and weakness. As the patient becomes severely dehydrated, the skin becomes dry and loose, and the eyeballs become soft and sunken. Abdominal pain is another symptom of DKA that may be accompanied by anorexia and vomiting. Kussmaul respirations (i.e., rapid, deep breathing associated with dyspnea) are the body's attempt to reverse metabolic acidosis through the exhalation of excess carbon dioxide. Acetone is identified on the breath as a sweet, fruity odor. Laboratory findings include a blood glucose level greater than 250 mg/dL, arterial blood pH less than 7.30, serum bicarbonate level less than 15 mEq/L, and moderate to high ketone levels in the urine or blood.

A diagnosis of hyperglycemic hyperosmolar nonketotic coma (HHNC) is made for a patient with type 2 diabetes who is brought to the emergency department in an unresponsive state. The nurse will anticipate the need to a. administer glargine (Lantus) insulin. b. initiate oxygen by nasal cannula. c. insert a large-bore IV catheter. d. give 50% dextrose as a bolus.

C Rationale: HHNC is initially treated with large volumes of IV fluids to correct hypovolemia. Regular insulin is administered, not a long-acting insulin. There is no indication that the patient requires oxygen. Dextrose solutions will increase the patient's blood glucose and would be contraindicated.

The client tells the nurse that the client really misses having sugar with tea in the morning. What is an alternative that the nurse could advise them to help sweeten their drink. a. Oatrim b. Olestra c. sucralose d. tannin

C Aspartame is the generic name for a sweetener composed of two amino acids, phenylalanine and aspartic acid. Olestra and Oatrim are fat replacers and tannin is an acid found in some foods such as tea.

A type 1 diabetic patient who was admitted with severe hypoglycemia and treated tells the nurse, "I did not have any of the usual symptoms of hypoglycemia." Which question by the nurse will help identify a possible reason for the patient's hypoglycemic unawareness? a. "Do you use any calcium-channel blocking drugs for blood pressure?" b. "Have you observed any recent skin changes?" c. "Do you notice any bloating feeling after eating?" d. "Have you noticed any painful new ulcerations or sores on your feet?"

C Rationale: Hypoglycemic unawareness is caused by autonomic neuropathy, which would also cause delayed gastric emptying. Calcium-channel blockers are not associated with hypoglycemic unawareness, although -adrenergic blockers can prevent patients from having symptoms of hypoglycemia. Skin changes can occur with diabetes, but these are not associated with autonomic neuropathy. If the patient can feel painful areas on the feet, neuropathy has not occurred.

A patient who has just been diagnosed with type 2 diabetes is 5 ft 4 in (160 cm) tall and weighs 182 pounds (82 kg). A nursing diagnosis of imbalanced nutrition: more than body requirements is developed. Which patient outcome is most important for this patient? a. The patient will have a diet and exercise plan that results in weight loss. b. The patient will state the reasons for eliminating simple sugars in the diet. c. The patient will have a glycosylated hemoglobin level of less than 7%. d. The patient will choose a diet that distributes calories throughout the day.

C Rationale: The complications of diabetes are related to elevated blood glucose, and the most important patient outcome is the reduction of glucose to near-normal levels. The other outcomes are also appropriate but are not as high in priority.

A diabetic patient is admitted with ketoacidosis and the health care provider writes all of the following orders. Which order should the nurse implement first? a. Start an infusion of regular insulin at 50 U/hr. b. Give sodium bicarbonate 50 mEq IV push. c. Infuse 1 liter of normal saline per hour. d. Administer regular IV insulin 30 U.

C Rationale: The most urgent patient problem is the hypovolemia associated with DKA, and the priority is to infuse IV fluids. The other actions can be accomplished after the infusion of normal saline is initiated.

The nurse is teaching care to client who has DM. Which of the following information should the nurse include in the teaching? Select all that apply. A. Remove calluses using over-the-counter remedies B. Apply lotion between toes C. Perform nail care after bathing D. Trim toenails straight across E. Wear closed-toe shoes

C, D, E perform nail care after bathing, when toenails are softer and easier to trim Trim toenails straight across to prevent injury to soft tissues of the toes. Wear closed-toe shoes to prevent injury to soft tissue the toes and feet.

Assuming the patient eats breakfast at 8:30 AM, lunch at noon, and dinner at 6:00 PM, he or she is at highest risk of hypoglycemia following an 8:00 AM dose of NPH insulin at what time? A. 10:00 AM B. 2:00 PM C. 5:00 PM D. 8:00 PM

C. 5:00 PM

The nurse is working with an overweight client who has a high-stress job and smokes. This client has just received a diagnosis of Type II Diabetes and has just been started on an oral hypoglycemic agent. Which of the following goals for the client which if met, would be most likely to lead to an improvement in insulin efficiency to the point the client would no longer require oral hypoglycemic agents? a. Comply with medication regimen 100% for 6 months b. Quit the use of any tobacco products by the end of three months c. Lose a pound a week until weight is in normal range for height and exercise 30 minutes daily d. Practice relaxation techniques for at least five minutes five times a day for at least five months

C. Lose a pound a week until weight is in normal range for height and exercise 30 minutes daily When type II diabetics lose weight through diet and exercise they sometimes have an improvement in insulin efficiency sufficient to the degree they no longer require oral hypoglycemic agents.

A thirty five year old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect? A: Atherosclerosis B: Diabetic nephropathy C: Autonomic neuropathy D: Somatic neuropathy

C: Autonomic neuropathy

Risk factors for type 2 diabetes include all of the following except: a. Advanced age b. Obesity c. Smoking d. Physical inactivity

C: smoking Additional risk factors for type 2 diabetes are a family history of diabetes, impaired glucose metabolism, history of gestational diabetes, and race/ethnicity. African-Americans, Hispanics/Latinos, Asian Americans, Native Hawaiians, Pacific Islanders, and Native Americans are at greater risk of developing diabetes than whites.

A 37-year-old forklift operator presents with shakiness, sweating, anxiety, and palpitations and tells the nurse he has type 1 diabetes mellitus. Which of the follow actions should the nurse do first? A. Inject 1 mg of glucagon subcutaneously. B. Administer 50 mL of 50% glucose I.V. C. Give 4 to 6 oz (118 to 177 mL) of orange juice. D. Give the client four to six glucose tablets.

Correct answer: C Because the client is awake and complaining of symptoms, the nurse should first give him 15 grams of carbohydrate to treat hypoglycemia. This could be 4 to 6 oz of fruit juice, five to six hard candies such as Lifesavers, or 1 tablespoon of sugar. When a client has worsening symptoms of hypoglycemia or is unconscious, treatment includes 1 mg of glucagon subcutaneously or intramuscularly, or 50 mL of 50% glucose I.V. The nurse may also give two to three glucose tablets for a hypoglycemic reaction.

2.Which statement would be correct for a patient with type 2 diabetes who was admitted to the hospital with pneumonia? a.The patient must receive insulin therapy to prevent ketoacidosis. b.The patient has islet cell antibodies that have destroyed the pancreas's ability to produce insulin. c.The patient has minimal or absent endogenous insulin secretion and requires daily insulin injections. d.The patient may have sufficient endogenous insulin to prevent ketosis but is at risk for hyperosmolar hyperglycemic syndrome.

D Rationale: Hyperosmolar hyperglycemic syndrome (HHS) is a life-threatening syndrome that can occur in a patient with diabetes who is able to produce enough insulin to prevent diabetic ketoacidosis (DKA) but not enough to prevent severe hyperglycemia, osmotic diuresis, and extracellular fluid depletion

During a teaching session, the nurse tells the client that 50% to 60% of daily calories should come from carbohydrates. What should the nurse say about the types of carbohydrates that can be eaten? a. Simple carbohydrates are absorbed more rapidly than complex carbohydrates. b. Simple sugars cause a rapid spike in glucose levels and should be avoided c. Simple sugars should never be consumed by someone with diabetes. d. Try to limit simple sugars to between 10% and 20% of daily calories.

D It is recommended that carbohydrates provide 50% to 60% of the daily calories. Approximately 40% to 50% should be from complex carbohydrates. The remaining 10% to 20% of carbohydrates could be from simple sugars. Research provides no evidence that carbohydrates from simple sugars are digested and absorbed more rapidly than are complex carbohydrates, and they do not appear to affect blood sugar control.

A hospitalized diabetic patient receives 12 U of regular insulin mixed with 34 U of NPH insulin at 7:00 AM. The patient is away from the nursing unit for diagnostic testing at noon, when lunch trays are distributed. The most appropriate action by the nurse is to a. save the lunch tray to be provided upon the patient's return to the unit. b. call the diagnostic testing area and ask that a 5% dextrose IV be started. c. ensure that the patient drinks a glass of milk or orange juice at noon in the diagnostic testing area. d. request that the patient be returned to the unit to eat lunch if testing will not be completed promptly.

D Rationale: Consistency for mealtimes assists with regulation of blood glucose, so the best option is for the patient to have lunch at the usual time. Waiting to eat until after the procedure is likely to cause hypoglycemia. Administration of an IV solution is unnecessarily invasive for the patient. A glass of milk or juice will keep the patient from becoming hypoglycemic but will cause a rapid rise in blood glucose because of the rapid absorption of the simple carbohydrate in these items.

A patient recovering from DKA asks the nurse how acidosis occurs. The best response by the nurse is that a. insufficient insulin leads to cellular starvation, and as cells rupture they release organic acids into the blood. b. when an insulin deficit causes hyperglycemia, then proteins are deaminated by the liver, causing acidic by-products. c. excess glucose in the blood is metabolized by the liver into acetone, which is acidic. d. an insulin deficit promotes metabolism of fat stores, which produces large amounts of acidic ketones.

D Rationale: Ketoacidosis is caused by the breakdown of fat stores when glucose is not available for intracellular metabolism. The other responses are inaccurate.

A patient with type 1 diabetes has received diet instruction as part of the treatment plan. The nurse determines a need for additional instruction when the patient says, a. "I may have an occasional alcoholic drink if I include it in my meal plan." b. "I will need a bedtime snack because I take an evening dose of NPH insulin." c. "I will eat meals as scheduled, even if I am not hungry, to prevent hypoglycemia." d. "I may eat whatever I want, as long as I use enough insulin to cover the calories."

D Rationale: Most patients with type 1 diabetes need to plan diet choices very carefully. Patients who are using intensified insulin therapy have considerable flexibility in diet choices but still should restrict dietary intake of items such as fat, protein, and alcohol. The other patient statements are correct and indicate good understanding of the diet instruction.

The nurse teaches the diabetic patient who rides a bicycle to work every day to administer morning insulin into the a. thigh. b. buttock. c. arm. d. abdomen.

D Rationale: Patients should be taught not to administer insulin into a site that will be exercised because exercise will increase the rate of absorption. The thigh, buttock, and arm are all exercised by riding a bicycle.

A program of weight loss and exercise is recommended for a patient with impaired fasting glucose (IFG). When teaching the patient about the reason for these lifestyle changes, the nurse will tell the patient that a. the high insulin levels associated with this syndrome damage the lining of blood vessels, leading to vascular disease. b. although the fasting plasma glucose levels do not currently indicate diabetes, the glycosylated hemoglobin will be elevated. c. the liver is producing excessive glucose, which will eventually exhaust the ability of the pancreas to produce insulin, and exercise will normalize glucose production. d. the onset of diabetes and the associated cardiovascular risks can be delayed or prevented by weight loss and exercise.

D Rationale: The patient with IFG is at risk for developing type 2 diabetes, but this risk can be decreased with lifestyle changes. Glycosylated hemoglobin levels will not be elevated in IFG and the Hb A1C test is not included in prediabetes testing. Elevated insulin levels do not cause the damage to blood vessels that can occur with IFG. The liver does not produce increased levels of glucose in IFG

A patient screened for diabetes at a clinic has a fasting plasma glucose level of 120 mg/dl (6.7 mmol/L). The nurse will plan to teach the patient about a. use of low doses of regular insulin. b. self-monitoring of blood glucose. c. oral hypoglycemic medications. d. maintenance of a healthy weight.

D Rationale: The patient's impaired fasting glucose indicates pre-diabetes and the patient should be counseled about LIFESTYLE CHANGES to prevent the development of type 2 diabetes. The patient with prediabetes does not require insulin or the oral hypoglycemics for glucose control and does not need to self-monitor blood glucose.

The nurse would include which statement when teaching a patient about insulin glargine? A. "You should inject this insulin just before meals because it is very fast acting." B. "The duration of action for this insulin is approximately 8 to10 hours, so you will need to take it twice a day." C. "You can mix this insulin with NPH insulin to enhance its effects." D. "You cannot mix this insulin with regular insulin and thus will have to take two injections."

D. "You cannot mix this insulin with regular insulin and thus will have to take two injections."

When taking a health history, the nurse screens for manifestations suggestive of diabetes type I. Which of the following manifestations are considered the primary manifestations of diabetes type I and would be most suggestive of diabetes type I and require follow-up investigation? a. Excessive intake of calories, rapid weight gain, and difficulty losing weight b. Poor circulation, wound healing, and leg ulcers, c. Lack of energy, weight gain, and depression d. An increase in three areas: thirst, intake of fluids, and hunger

D. An increase in three areas: thirst, intake of fluids, and hunger The primary manifestations of diabetes type I are polyuria (increased urine output), polydipsia (increased thirst), polyphagia (increased hunger).

You are doing some teaching with a client who is starting on a sulfonylurea antidiabetic agent. The client mentions that he usually has a couple of beers each night and takes an aspirin each day to prevent heart attack and/or strokes. Which of the following responses would be best on the part of the nurse? a. As long as you only drink two beers and take one aspirin, this should not be a problem b. The aspirin is alright but you need to give up drinking any alcoholic beverages c. Aspirin and alcohol will cause the stomach to bleed more when on a sulfonylurea drug d. Taking alcohol and/or aspirin with a sulfonylurea drug can cause development of hypoglycemia

D. Taking alcohol and/or aspirin with a sulfonylurea drug can cause development of hypoglycemia Alcohol and/or aspirin taken with a sulfonylurea can cause development of hypoglycemia.

An external insulin pump is prescribed for a client with diabetes mellitus and the client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump: a) is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals b) continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels c) is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream d) gives a small continuously dose of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dose form the pump before each meal

D.) gives a small continuously dose of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dose form the pump before each meal An insulin pump provides a small continuous dose of regular insulin subcutaneously throughout the day and night, and the client can self-administer a bolus with an additional dose from the pump before each meal as needed. Regular insulin is used in an insulin pump. An external pump is not attached surgically to the pancreas.

Prediabetes is associated with all of the following except: a. Increased risk of developing type 2 diabetes b. Impaired glucose tolerance c. Increased risk of heart disease and stroke d. Increased risk of developing type 1 diabetes

D: Increased risk of developing type 1 diabetes Persons with elevated glucose levels that do not yet meet the criteria for diabetes are considered to have prediabetes and are at increased risk of developing type 2 diabetes. Weight loss and increasing physical activity can help people with prediabetes prevent or postpone the onset of type 2 diabetes.

The nurse assisting in the admission of a client with diabetic ketoacidosis will anticipate the physician ordering which of the following types of intravenous solution if the client cannot take fluids orally? a. 0.45% normal saline solution b. Lactated Ringer's solution c. 0.9 normal saline solution d. 5% dextrose in water (D5W)

a. 0.45% normal saline solution

Which of the following factors are risks for the development of diabetes mellitus? (Select all that apply.) a. Age over 45 years b. Overweight with a waist/hip ratio >1 c. Having a consistent HDL level above 40 mg/dl d. Maintaining a sedentary lifestyle

a. Age over 45 years b. Overweight with a waist/hip ratio >1 d. Maintaining a sedentary lifestyle Aging results in reduced ability of beta cells to respond with insulin effectively. Overweight with waist/hip ratio increase is part of the metabolic syndrome of DM II. There is an increase in atherosclerosis with DM due to the metabolic syndrome and sedentary lifestyle.

Blood sugar is well controlled when Hemoglobin A1C is: a. Below 7% b. Between 12%-15% c. Less than 180 mg/dL d. Between 90 and 130 mg/dL

a. Below 7% A1c measures the percentage of hemoglobin that is glycated and determines average blood glucose during the 2 to 3 months prior to testing. Used as a diagnostic tool, A1C levels of 6.5% or higher on two tests indicate diabetes. A1C of 6% to 6.5% is considered prediabetes.

Which laboratory test should a nurse anticipate a physician would order when an older person is identified as high-risk for diabetes mellitus? (Select all that apply.) a. Fasting Plasma Glucose (FPG) b. Two-hour Oral Glucose Tolerance Test (OGTT) c. Glycosylated hemoglobin (HbA1C) d. Finger stick glucose three times daily

a. Fasting Plasma Glucose (FPG) b. Two-hour Oral Glucose Tolerance Test (OGTT) When an older person is identified as high-risk for diabetes, appropriate testing would include FPG and OGTT. A FPG greater than 140 mg/dL usually indicates diabetes. The OGTT is to determine how the body responds to the ingestion of carbohydrates in a meal. HbA1C evaluates long-term glucose control. A finger stick glucose three times daily spot-checks blood glucose levels.

Which of the following is accurate pertaining to physical exercise and type 1 diabetes mellitus? a. Physical exercise can slow the progression of diabetes mellitus. b. Strenuous exercise is beneficial when the blood glucose is high. c. Patients who take insulin and engage in strenuous physical exercise might experience hyperglycemia. d. Adjusting insulin regimen allows for safe participation in all forms of exercise.

a. Physical exercise can slow the progression of diabetes mellitus. Physical exercise slows the progression of diabetes mellitus, because exercise has beneficial effects on carbohydrate metabolism and insulin sensitivity. Strenuous exercise can cause retinal damage, and can cause hypoglycemia. Insulin and foods both must be adjusted to allow safe participation in exercise.

Which one of the following methods/techniques will the nurse use when giving insulin to a thin person? [Hint] A. Pinch the skin up and use a 90 degree angle B. Use a 45 degree angle with the skin pinched up C. Massage the area of injection after injecting the insulin D. Warm the skin with a warmed towel or washcloth prior to the injection

a. Pinch the skin up and use a 90 degree angle The best angle for a thin person is 90 degrees with the skin pinched up. The area is not massaged and it is not necessary to warm it.

A patient newly diagnosed with Type I DM is being seen by the home health nurse. The doctors orders include: 1200 calorie ADA diet, 15 units NPH insulin before breakfast, and check blood sugar qid. When the nurse visits the patient at 5 pm, the nurse observes the man performing blood sugar analysis. The result is 50 mg/dL. The nurse would expect the patient to be a. confused with cold, clammy skin an pulse of 110 b. lethargic with hot dry dkin and rapid deep respirations c. alert and cooperative with BP of 130/80 and respirations of 12 d. short of breath, with distended neck veins and bounding pulse of 96.

a. confused with cold, clammy skin an pulse of 110 hypoglycemia

he goal for pre-prandial blood glucose for those with Type 1 diabetes mellitus is: a. <80 mg/dl b. < 130 mg/dl c. <180 mg/dl d. <6%

b. < 130 mg/dl

Which of these laboratory values noted by the nurse when reviewing the chart of a diabetic patient indicates the need for further assessment of the patient? a. Fasting blood glucose of 130 mg/dl b. Noon blood glucose of 52 mg/dl c. Glycosylated hemoglobin of 6.9% d. Hemoglobin A1C of 5.8%

b. Noon blood glucose of 52 mg/dl The nurse should assess the patient with a blood glucose level of 52 mg/dl for symptoms of hypoglycemia, and give the patient some carbohydrate-containing beverage such as orange juice. The other values are within an acceptable range for a diabetic patient.

One of the benefits of Glargine (Lantus) insulin is its ability to: a. Release insulin rapidly throughout the day to help control basal glucose. b. Release insulin evenly throughout the day and control basal glucose levels. c. Simplify the dosing and better control blood glucose levels during the day. d. Cause hypoglycemia with other manifestation of other adverse reactions.

b. Release insulin evenly throughout the day and control basal glucose levels. Glargine (Lantus) insulin is designed to release insulin evenly throughout the day and control basal glucose levels.

The guidelines for Carbohydrate Counting as medical nutrition therapy for diabetes mellitus includes all of the following EXCEPT: a. Flexibility in types and amounts of foods consumed b. Unlimited intake of total fat, saturated fat and cholesterol c. Including adequate servings of fruits, vegetables and the dairy group d. Applicable to with either Type 1 or Type 2 diabetes mellitus

b. Unlimited intake of total fat, saturated fat and cholesterol

A 1200-calorie diet and exercise are prescribed for a patient with newly diagnosed type 2 diabetes. The patient tells the nurse, "I hate to exercise! Can't I just follow the diet to keep my glucose under control?" The nurse teaches the patient that the major purpose of exercise for diabetics is to a. increase energy and sense of well-being, which will help with body image. b. facilitate weight loss, which will decrease peripheral insulin resistance. c. improve cardiovascular endurance, which is important for diabetics. d. set a successful pattern, which will help in making other needed changes.

b. facilitate weight loss, which will decrease peripheral insulin resistance. Rationale: Exercise is essential to decrease insulin resistance and improve blood glucose control. Increased energy, improved cardiovascular endurance, and setting a pattern of success are secondary benefits of exercise, but they are not the major reason.

A client is brought to the emergency room in an unresponsive state, and a diagnosis of hyperglycemic hyperosmolar nonketotic syndrome is made. The nurse would immediately prepare to initiate which of the following anticipated physician's orders? a) endotracheal intubation b) 100 units of NPH insulin c) intravenous infusion of normal saline d) intravenous infusion of sodium bicarbonate

c) intravenous infusion of normal saline The primary goal of treatment in hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is to rehydrate the client to restore fluid volume and to correct electrolyte deficiency. Intravenous fluid replacement is similar to that administered in diabetic ketoacidosis (DKA) and begins with IV infusion of normal saline. Regular insulin, not NPH insulin, would be administered. The use of sodium bicarbonate to correct acidosis is avoided because it can precipitate a further drop in serum potassium levels. Intubation and mechanical ventilation are not required to treat HHNS.

Which of the following persons would most likely be diagnosed with diabetes mellitus? A 44-year-old: a. Caucasian woman. b. Asian woman. c. African-American woman. d. Hispanic male.

c. African-American woman. Age-specific prevalence of diagnosed diabetes mellitus (DM) is higher for African-Americans and Hispanics than for Caucasians. Among those younger than 75, black women had the highest incidence.

Which of the following diabetes drugs acts by decreasing the amount of glucose produced by the liver? a. Sulfonylureas b. Meglitinides c. Biguanides d. Alpha-glucosidase inhibitors

c. Biguanides Biguanides, such as metformin, lower blood glucose by reducing the amount of glucose produced by the liver. Sulfonylureas and Meglitinides stimulate the beta cells of the pancreas to produce more insulin. Alpha-glucosidase inhibitors block the breakdown of starches and some sugars, which helps to reduce blood glucose levels

The nurse is having difficulty obtaining a capillary blood sample from a client's finger to measure blood glucose using a blood glucose monitor. Which procedure will increase the blood flow to the area to ensure an adequate specimen? a. Raise the hand on a pillow to increase venous flow. b. Pierce the skin with the lancet in the middle of the finger pad. c. Wrap the finger in a warm cloth for 30-60 seconds. d. Pierce the skin at a 45-degree angle.

c. Wrap the finger in a warm cloth for 30-60 seconds. The hand is lowered to increase venous flow. The finger is pierced lateral to the middle of the pad perpendicular to the skin surface.

A patient received 6 units of REGULAR INSULIN 3 hours ago. The nurse would be MOST concerned if which of the following was observed? a. kussmaul respirations and diaphoresis b. anorexia and lethargy c. diaphoresis and trembling d. headache and polyuria

c. diaphoresis and trembling indicates hypoglycemia

client newly diagnosed with diabetes mellitus has been stabilized with daily insulin injections. A nurse prepares a discharge teaching plan regarding the insulin and plans to reinforce which of the following concepts? a) always keep insulin vials refrigerated b) ketones in the urine signify a need for less insulin c) increase the amount of insulin before unusual exercise d) systematically rotate insulin injections within one anatomic site

d) systematically rotate insulin injections within one anatomic site Insulin doses should not be adjusted nor increased before unusual exercise. If ketones are found in the urine, it possibly may indicate the need for additional insulin. To minimize the discomfort associated with insulin injections, insulin should be administered at room temperature. Injection sites should be rotated systematically within one anatomic site.

When working in the community, the nurse will recommend routine screening for diabetes when the person has one or more of seven risk criteria. Which of the following persons that the nurse comes in contact with most needs to be screened for diabetes based on the seven risk criteria? a. A woman who is at 90% of standard body weight after delivering an eight-pound baby b. A middle-aged Caucasian male c. An older client who is hypotensive d. A client with an HDL cholesterol level of 40 mg/dl and a triglyceride level of 300 mg/dl

d. A client with an HDL cholesterol level of 40 mg/dl and a triglyceride level of 300 mg/dl The seven risk criteria include: greater than 120% of standard body weight, Certain races but not including Caucasian, delivery of a baby weighing more than 9 pounds or a diagnosis of gestational diabetes, hypertensive, HDL greater than 35 mg/dl or triglyceride level greater than 250 or a triglyceride level of greater than 250 mg/dl, and, lastly, impaired glucose tolerance or impaired fasting glucose on prior testing.

The nurse is providing education to a client recently diagnosed with type 1 diabetes mellitus. What information will the nurse include when teaching about the characteristics of this​ disease? a. Hyperosmolar hyperglycemia state b. Insulin resistance c. Rapid onset of disease d. Breakdown of fats and proteins

d. Breakdown of fats and proteins

A frail elderly patient with a diagnosis of type 2 diabetes mellitus has been ill with pneumonia. The client's intake has been very poor, and she is admitted to the hospital for observation and management as needed. What is the most likely problem with this patient? a. Insulin resistance has developed. b. Diabetic ketoacidosis is occurring. c. Hypoglycemia unawareness is developing. d. Hyperglycemic hyperosmolar non-ketotic coma

d. Hyperglycemic hyperosmolar non-ketotic coma Illness, especially with the frail elderly patient whose appetite is poor, can result in dehydration and HHNC. Insulin resistance usually is indicated by a daily insulin requirement of 200 units or more. Diabetic ketoacidosis, an acute metabolic condition, usually is caused by absent or markedly decreased amounts of insulin.

Proliferative retinopathy is often treated using: a. Tonometry b. Fluorescein angiogram c. Antibiotics d. Laser surgery

d. Laser surgery Scatter laser treatment is used to shrink abnormal blood vessels in an effort to preserve vision. When there is significant bleeding in the eye, it is removed in a procedure known as vitrectomy. Tonometry is a diagnostic test that measures pressure inside the eye. A fluorescein angiogram is a diagnostic test that traces the flow of dye through the blood vessels in the retina; it is used to detect macular edema.

Of which of the following symptoms might an older woman with diabetes mellitus complain? a. Anorexia b. Pain intolerance c. Weight loss d. Perineal itching

d. Perineal itching

A college student who has type 1 diabetes normally walks each evening as part of an exercise regimen. The student now plans to take a swimming class every day at 1:00 PM. The clinic nurse teaches the patient to a. delay eating the noon meal until after the swimming class. b. increase the morning dose of neutral protamine Hagedorn (NPH) insulin on days of the swimming class. c. time the morning insulin injection so that the peak occurs while swimming. d. check glucose level before, during, and after swimming.

d. check glucose level before, during, and after swimming. Rationale: The change in exercise will affect blood glucose, and the patient will need to monitor glucose carefully to determine the need for changes in diet and insulin administration. Because exercise tends to decrease blood glucose, patients are advised to eat before exercising. Increasing the morning NPH or timing the insulin to peak during exercise may lead to hypoglycemia, especially with the increased exercise.

A 63-year-old patient is newly diagnosed with type 2 diabetes. When developing an education plan, the nurse's first action should be to a. assess the patient's perception of what it means to have type 2 diabetes. b. demonstrate how to check glucose using capillary blood glucose monitoring. c. ask the patient's family to participate in the diabetes education program. d. discuss the need for the patient to actively participate in diabetes management.

A Rationale: Before planning education, the nurse should assess the patient's interest in and ability to self-manage the diabetes. After assessing the patient, the other nursing actions may be appropriate, but planning needs to be individualized to each patient.

4.Which statement by the patient with type 2 diabetes is accurate? a."I am supposed to have a meal or snack if I drink alcohol." b."I am not allowed to eat any sweets because of my diabetes." c."I do not need to watch what I eat because my diabetes is not the bad kind." d."The amount of fat in my diet is not important. Only carbohydrates raise my blood sugar."

A Rationale: Alcohol should be consumed with food to reduce the risk of hypoglycemia.
