1.
A patient with newly diagnosed type 2 diabetes mellitus asks the nurse what “type 2” means in relation to diabetes. Which statement by the nurse about type 2 diabetes is correct?
Correct Answer
D. Changes in diet and exercise may be sufficient to control blood glucose levels in type 2 diabetes
Explanation
ANS: D
For some patients, changes in lifestyle are sufficient for blood glucose control. Insulin is frequently used for type 2 diabetes, complications are equally severe as for type 1 diabetes, and type 2 diabetes is usually diagnosed with routine laboratory testing or after a patient develops complications such as frequent yeast infections.
2.
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
Correct Answer
C. Lifestyle changes to lower blood glucose.
Explanation
ANS: C
The patient’s impaired fasting glucose indicates prediabetes 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.
3.
Which action by a type 1 diabetic patient indicates that the nurse should implement teaching about exercise and glucose control?
Correct Answer
D. The patient increases daily exercise when ketones are present in the urine.
Explanation
ANS: D
When the patient is ketotic, exercise may result in an increase in blood glucose level. Type 1 diabetic patients should be taught to avoid exercise when ketosis is present. The other statements are correct.
4.
When assessing the patient experiencing the onset of symptoms of type 1 diabetes, which question is most appropriate for the nurse to ask?
Correct Answer
A. “Have you lost any weight lately?”
Explanation
ANS: A
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.
5.
To evaluate the effectiveness of treatment for a patient with type 2 diabetes who is scheduled for a follow-up visit in the clinic, which test will the nurse plan to schedule for the patient?
Correct Answer
D. Glycosylated hemoglobin level
Explanation
ANS: D
The glycosylated hemoglobin (Hb A1C) test shows the overall control of glucose over 90 to 120 days. A fasting blood level indicates only the glucose level at one time. Urine glucose testing is not an accurate reflection of blood glucose level and does not reflect the glucose over a prolonged time. Oral glucose tolerance testing is done to diagnose diabetes, but is not used for monitoring glucose control once diabetes has been diagnosed.
6.
A patient who has just been diagnosed with type 2 diabetes has a nursing diagnosis of imbalanced nutrition: more than body requirements. Which patient goal is most important for this patient?
Correct Answer
A. The patient will have a glycosylated hemoglobin level of less than 7%.
Explanation
ANS: A
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 also are appropriate but are not as high in priority.
7.
A patient who has type 1 diabetes plans to take a swimming class daily at 1:00 PM. The clinic nurse will plan to teach the patient to
Correct Answer
A. Check glucose level before, during, and after swimming.
Explanation
ANS: A
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.
8.
An 18-year-old with newly diagnosed type 1 diabetes has received diet instruction. The nurse determines a need for additional instruction when the patient says,
Correct Answer
C. “I may eat whatever I want, as long as I use enough insulin to cover the calories.”
Explanation
ANS: C
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.
9.
Which action is most important for the nurse to take in order to assist a diabetic patient to engage in moderate daily exercise?
Correct Answer
B. Determine what type of exercise activities the patient enjoys.
Explanation
ANS: B
Since consistency with exercise is important, assessment for the types of exercise that the patient finds enjoyable is the most important action by the nurse in ensuring adherence to an exercise program. The other actions also will be implemented, but are not the most important in improving compliance.
10.
The nurse has been teaching the patient to administer a dose of 10 units of regular insulin and 28 units of NpH insulin. The statement by the patient that indicates a need for additional instruction is,
Correct Answer
A. “I need to rotate injection sites among my arms, legs, and abdomen each day.”
Explanation
ANS: A
Rotating sites is no longer recommended because there is more consistent insulin absorption when the same site is used consistently. The other patient statements are accurate and indicate that no additional instruction is needed.
11.
After the nurse has finished teaching a patient about self-administration of the prescribed aspart (NovoLog) insulin, which patient action indicates good understanding of the teaching?
Correct Answer
B. The patient cleans the skin with soap and water before insulin administration.
Explanation
ANS: B
Cleaning the skin with soap and water or with alcohol is acceptable. Insulin should not be frozen. The patient should leave the syringe in place for about 5 seconds after injection to be sure that all the insulin has been injected. The upper abdominal area is one of the preferred areas for insulin injection.
12.
A patient receives aspart (NovoLog) insulin at 8:00 AM. Which time will it be most important for the nurse to monitor for symptoms of hypoglycemia?
Correct Answer
A. 9:00 AM
Explanation
ANS: A
The rapid-acting insulins peak in 1 to 3 hours. The patient is not at a high risk for hypoglycemia at the other listed times, although hypoglycemia may occur.
13.
Which patient action indicates a good understanding of the nurse’s teaching about the use of an insulin pump?
Correct Answer
B. The patient programs the pump to deliver an insulin bolus after eating.
Explanation
ANS: B
In addition to the basal rate of insulin infusion, the patient will adjust the pump to administer a bolus after each meal, with the dosage depending on the oral intake. The insertion site should be changed every 2 or 3 days. There is more flexibility in diet and exercise when an insulin pump is used. The pump will deliver a basal insulin rate 24 hours a day.
14.
When teaching a diabetic patient who has just been started on intensive insulin therapy about mealtime coverage, which type of insulin will the nurse need to discuss?
Correct Answer
B. Lispro (Humalog)
Explanation
ANS: B
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.
15.
Which information will the nurse include when teaching a patient who has type 2 diabetes about glyburide (Micronase, DiaBeta, Glynase)?
Correct Answer
B. Glyburide stimulates insulin production and release from the pancreas.
Explanation
ANS: B
The sulfonylureas stimulate the production and release of insulin from the pancreas. If the glucose level is low, the patient should contact the health care provider before taking the glyburide, because hypoglycemia can occur with this category of medication. Metformin should be held for 48 hours after administration of IV contrast media, but this is not necessary for glyburide. Glucagon secretion is not affected by glyburide.
16.
Which patient statement after the nurse has completed teaching a patient with type 2 diabetes about taking glipizide (Glucotrol) indicates a need for additional teaching?
Correct Answer
D. “My diabetes is not as likely to cause complications as if I needed to take insulin.”
Explanation
ANS: D
The patient should understand that type 2 diabetes places the patient at risk for many complications and that good glucose control is as important when taking oral agents as when using insulin. The other statements are accurate and indicate good understanding of the use of glipizide.
17.
A patient with type 2 diabetes that is well-controlled with metformin (Glucophage) develops an allergic rash to an antibiotic and the health care provider prescribes prednisone (Deltasone). The nurse will anticipate that the patient may
Correct Answer
B. Require administration of insulin while taking prednisone.
Explanation
ANS: B
Glucose levels increase when patients are taking corticosteroids, and insulin may be required to control blood glucose. Hypoglycemia is not a side effect of prednisone. Rashes are not an adverse effect caused by taking metformin and prednisone simultaneously. The patient may have an increased appetite when taking prednisone, but will not need a diet that is higher in calories.
18.
A hospitalized diabetic patient who received 34 U of NpH insulin at 7:00 AM is away from the nursing unit, awaiting diagnostic testing when lunch trays are distributed. To prevent hypoglycemia, the best action by the nurse is to
Correct Answer
D. Request that the patient be returned to the unit to eat lunch if testing will not be completed promptly.
Explanation
ANS: D
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.
19.
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
Correct Answer
B. Chooses a puncture site in the center of the finger pad.
Explanation
ANS: B
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.
20.
Which action should the nurse take first when teaching a patient who is newly diagnosed with type 2 diabetes about home management of the disease?
Correct Answer
B. Assess the patient’s perception of what it means to have diabetes mellitus.
Explanation
ANS: B
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.
21.
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
Correct Answer
B. Insert a large-bore IV catheter.
Explanation
ANS: B
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.
22.
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
Correct Answer
B. Monitor blood glucose every 4 hours and notify the clinic if it continues to rise.
Explanation
ANS: B
Infection and other stressors increase blood glucose levels and the patient will need to test blood glucose frequently, treat elevations appropriately with lispro 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 diabetic ketoacidosis (DKA). Decreasing carbohydrate or caloric intake is not appropriate because the patient will need more calories when ill. Glycosylated hemoglobins are not used to test for short-term alterations in blood glucose.
23.
The health care provider suspects the Somogyi effect in a patient whose 7:00 AM blood glucose is 220 mg/dL. Which action will the nurse plan to take?
Correct Answer
A. Check the patient’s blood glucose at 3:00 AM.
Explanation
ANS: A
If the Somogyi effect is causing the patient’s increased morning glucose level, the patient will experience hypoglycemia between 2 and 4 AM. The dose of insulin will be reduced, rather than increased. A bedtime snack is used to prevent hypoglycemic episodes during the night
24.
Intramuscular glucagon is administered to an unresponsive patient for treatment of hypoglycemia. Which action should the nurse take after the patient regains consciousness?
Correct Answer
B. Give the patient a snack of crackers and peanut butter.
Explanation
ANS: B
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.
25.
Which question by the nurse will help identify autonomic neuropathy in a diabetic patient?
Correct Answer
B. “Do you notice any bloating feeling after eating?”
Explanation
ANS: B
Autonomic neuropathy can cause delayed gastric emptying, which results in a bloated feeling for the patient. The other questions also are appropriate to ask, but would not help in identifying autonomic neuropathy.
26.
A patient with type 2 diabetes has sensory neuropathy of the feet and legs and peripheral arterial disease. Which information will the nurse include in patient teaching?
Correct Answer
A. Choose flat-soled leather shoes.
Explanation
ANS: A
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.
27.
The nurse obtains the following information about a patient before administration of metformin (Glucophage). Which finding indicates a need to contact the health care provider before giving the metformin?
Correct Answer
B. The patient’s blood urea nitrogen (BUN) level is 60 mg/dL.
Explanation
ANS: B
The BUN indicates impending renal failure and metformin should not be used in patients with renal failure. The other findings are not contraindications to the use of metformin.
28.
Amitriptyline (Elavil) is prescribed for a diabetic patient who has burning foot pain at night. Which information should the nurse include when teaching the patient about the new medication?
Correct Answer
D. Amitriptyline will help prevent the transmission of pain impulses to the brain
Explanation
ANS: D
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.
29.
A patient with type 2 diabetes is admitted for an outpatient coronary arteriogram. Which information obtained by the nurse is most important to report to the health care provider before the procedure?
Correct Answer
C. The patient took the prescribed metformin (GlucopHage) today.
Explanation
ANS: C
To avoid lactic acidosis, metformin should be discontinued a day or 2 before the coronary arteriogram and should not be used for 48 hours after IV contrast media are administered. The other patient data also will be reported but do not indicate any need to reschedule the procedure.
30.
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?
Correct Answer
D. The patient disposes of the open vials of glargine and regular insulin after 4 weeks.
Explanation
ANS: D
Insulin can be stored at room temperature for 4 weeks. Glargine should not be mixed with other insulins or prefilled and stored. Short-acting regular insulin is administered before meals, while glargine is given once daily.
31.
The nurse teaches the diabetic patient who rides a bicycle to work every day to administer morning insulin into the
Correct Answer
D. Abdomen.
Explanation
ANS: D
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.
32.
Which information about a patient who receives rosiglitazone (Avandia) is most important for the nurse to report immediately to the health care provider?
Correct Answer
D. The patient has chest pressure when ambulating.
Explanation
ANS: D
Rosiglitazone can cause myocardial ischemia. The nurse should immediately notify the health care provider and expect orders to discontinue the medication. There is no urgent need to discuss the other data with the health care provider.
33.
A pregnant patient who has no personal history of diabetes, but does have a parent who is diabetic is scheduled for the first prenatal visit. Which action will the nurse plan to take on this initial visit?
Correct Answer
B. Discuss the need for a fasting blood glucose level.
Explanation
ANS: B
Patients at high risk for gestational diabetes should be screened for diabetes on the initial prenatal visit. An oral glucose tolerance test also may be used to check for diabetes, but it would be done before the twenty fourth week. The other actions also may be needed (depending on whether the patient develops gestational diabetes), but they are not the first actions that the nurse should take.
34.
A patient is admitted with diabetic ketoacidosis (DKA) and has a serum potassium level of 2.9 mEq/L. Which action prescribed by the health care provider should the nurse take first?
Correct Answer
B. Place the patient on a cardiac monitor.
Explanation
ANS: B
Hypokalemia can lead to potentially fatal dysrhythmias such as ventricular tachycardia and ventricular fibrillation, which would be detected with ECG monitoring. Since potassium must be infused over at least 1 hour, the nurse should initiate cardiac monitoring before infusion of potassium. Insulin should not be administered without cardiac monitoring, since insulin infusion will further decrease potassium levels. Urine glucose and ketone levels are not urgently needed to manage the patient’s care.
35.
A diabetic patient is admitted with ketoacidosis and the health care provider writes these orders. Which order should the nurse implement first?
Correct Answer
B. Infuse 1 liter of normal saline per hour.
Explanation
ANS: B
The most urgent patient problem is the hypovolemia associated with diabetic ketoacidosis (DKA), and the priority is to infuse IV fluids. The other actions can be accomplished after the infusion of normal saline is initiated.
36.
When the nurse is assessing a patient who is recovering from an episode of diabetic ketoacidosis, the patient reports feeling anxious, nervous, and sweaty. Which action should the nurse take first?
Correct Answer
B. Obtain a glucose reading using a finger stick.
Explanation
ANS: B
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. Administration of lispro would drop the patient’s glucose further.
37.
Which information from the patient’s health history is most important for the nurse to communicate to the health care provider when a patient has an order for an oral glucose tolerance test?
Correct Answer
A. The patient uses oral contraceptives.
Explanation
ANS: A
Oral contraceptive use may falsely elevate oral glucose tolerance test (OGTT) values. A viral illness 2 months previously may be associated with the onset of type 1 diabetes but will not falsely affect the OGTT. Exercise and a family history of diabetes both can affect blood glucose but will not lead to misleading information from the OGTT.
38.
Which of these laboratory values, noted by the nurse when reviewing the chart of a hospitalized diabetic patient, indicates the need for rapid assessment of the patient?
Correct Answer
B. Noon blood glucose of 52 mg/dL
Explanation
ANS: B
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.
39.
The nurse and LPN/LVN are caring for a type 2 diabetic patient who is admitted for gallbladder surgery. Which nursing action can the nurse delegate to the LPN/LVN?
Correct Answer
C. Administer the prescribed lispro (Humalog) insulin before transferring the patient to surgery.
Explanation
ANS: C
LPN/LVN education and scope of practice includes administration of insulin. Communication about patient status with other departments, planning, and patient teaching are skills that require RN education and scope of practice.
