The nurse obtains the following information about a patient before administration of metformin. Which of the following findings indicate a need to contact the health care provider before giving the metformin?
- A. The patient's blood glucose level is 9.2 mmol/L.
- B. The patient's blood urea nitrogen (BUN) level is 21.4 mmol/L.
- C. The patient is scheduled for a chest x-ray in an hour.
- D. The patient has gained 1 kg since yesterday.
Correct Answer: B
Rationale: The BUN indicates impending renal failure and metformin should not be used in patients with renal or hepatic impairment. The other findings are not contraindications to the use of metformin.

A patient with type 2 diabetes that is well-controlled with metformin develops an allergic rash to an antibiotic and the health care provider prescribes prednisone. Which of the following information should the nurse anticipate while the patient is taking the prednisone?
- A. A diet higher in calories
- B. Administration of insulin
- C. Development of acute hypoglycemia
- D. Appearance of a rash caused by metformin-prednisone interactions
Correct Answer: B
Rationale: Glucose levels increase when patients are taking corticosteroids, and insulin may be required to control blood glucose. Hypoglycemia is not an adverse 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.
The nurse is caring for a patient who has just been diagnosed with type 2 diabetes and has a nursing diagnosis of imbalanced nutrition: more than body requirements. Which of the following patient goals is most important?
- A. The patient will have a glycosylated hemoglobin level of less than 7%
- B. The patient will have a diet and exercise plan that results in weight loss.
- C. The patient will choose a diet that distributes calories throughout the day.
- D. The patient will state the reasons for eliminating simple sugars in the diet.
Correct Answer: A
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 also are appropriate but are not as high in priority.
Which of the following questions by the nurse will help identify autonomic neuropathy in a patient with diabetes?
- A. Have you observed any recent skin changes?
- B. Do you notice any bloating feeling after eating?
- C. Do you need to increase your insulin dosage when you are stressed?
- D. Have you noticed any painful new ulcerations or sores on your feet?
Correct Answer: B
Rationale: Autonomic neuropathy can cause delayed gastric emptying, which results in a bloated feeling for the patient. The other questions are also appropriate to ask, but would not help in identifying autonomic neuropathy.
After the nurse has finished teaching a patient about self-administration of the prescribed aspart insulin, which of the following patient actions indicate good understanding of the teaching?
- A. The patient avoids injecting the insulin into the upper abdominal area.
- B. The patient cleans the skin with soap and water before insulin administration.
- C. The patient places the insulin back in the freezer after administering the prescribed insulin dose.
- D. The patient pushes the plunger down and immediately removes the syringe from the injection site.
Correct Answer: B
Rationale: The use of an alcohol swab on the site before self-injection is no longer recommended. Routine hygiene such as washing with soap and rinsing with water is adequate. 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.
Which of the following patient teaching information is most important for the nurse to communicate to a patient with gestational diabetes?
- A. Delivery will not affect blood glucose levels.
- B. Exercise should be avoided in the last month of pregnancy.
- C. Monitoring of blood glucose can stop as soon as the baby is delivered.
- D. A postpartum OGTT will be done at 2 months.
Correct Answer: D
Rationale: Women should be screened postpartum to determine their glucose status. The 2008 CDA guidelines recommend a 75-g oral glucose tolerance test (OGTT) be done between 6 weeks and 6 months postpartum. Delivery may affect blood glucose levels. Exercise is not to be avoided. Monitoring of blood glucose will continue into the postpartum period until levels are within normal limits.
