A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?
- A. Administer intravenous insulin
- B. Start an intravenous line and infuse normal saline
- C. Monitor serum potassium levels
- D. Obtain an arterial blood gas (ABG)
Correct Answer: B
Rationale: The correct first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.

The client with newly diagnosed diabetes mellitus is being taught about managing blood glucose levels. Which statement indicates a need for further teaching?
- A. I will rotate my insulin injection sites to avoid tissue damage.
- B. I will monitor my blood glucose levels before each meal.
- C. I can eat unlimited fruit as it is healthy.
- D. I should carry a fast-acting carbohydrate with me at all times.
Correct Answer: C
Rationale: Choice C indicates a need for further teaching because stating 'I can eat unlimited fruit as it is healthy' is incorrect. While fruits are healthy, they also contain natural sugars that can affect blood glucose levels. Portion control is crucial to managing blood glucose levels effectively. Choices A, B, and D demonstrate correct understanding. Rotating insulin injection sites helps prevent tissue damage, monitoring blood glucose levels before meals aids in managing diabetes effectively, and carrying a fast-acting carbohydrate is essential to treat hypoglycemia promptly.
After taking glipizide (Glucotrol) for 9 months, a male client experiences secondary failure. What would the nurse expect the physician to do?
- A. Initiate insulin therapy.
- B. Switch the client to a different oral antidiabetic agent.
- C. Prescribe an additional oral antidiabetic agent.
- D. Restrict carbohydrate intake to less than 30% of the total caloric intake.
Correct Answer: A
Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.
The client with type 2 DM is being instructed by the nurse about the importance of controlling blood glucose levels. The nurse should emphasize that uncontrolled blood glucose can lead to:
- A. Increased risk of heart disease and stroke.
- B. Improved wound healing.
- C. Reduced need for medication.
- D. Decreased risk of infection.
Correct Answer: A
Rationale: Uncontrolled blood glucose levels are associated with an increased risk of cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, leading to atherosclerosis, which can increase the likelihood of heart disease and stroke. Improved wound healing (choice B) is not a consequence of uncontrolled blood glucose levels; in fact, high blood sugar levels can impair wound healing. Reduced need for medication (choice C) is inaccurate because uncontrolled blood glucose usually necessitates more medication to manage the condition. Decreased risk of infection (choice D) is also misleading as high blood glucose levels can compromise the immune system, making individuals more susceptible to infections.
A client with DM is scheduled to have surgery. The nurse should plan to:
- A. Give the client a regular diet as ordered.
- B. Hold the client's insulin on the morning of surgery.
- C. Monitor the client's blood glucose level closely during the perioperative period.
- D. Have the client stop taking insulin 48 hours before surgery.
Correct Answer: C
Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. This is essential to ensure that the client's blood glucose levels remain within the target range and to prevent complications such as hypo- or hyperglycemia. Choices A, B, and D are incorrect because giving a regular diet as ordered, holding insulin on the morning of surgery, or stopping insulin 48 hours before surgery can lead to uncontrolled blood glucose levels, posing risks to the client's safety during the surgical procedure.
A client with DM visits the health care clinic. The client's diabetes has been well controlled with glyburide (Diabeta), 5 mg PO daily, but recently the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?
- A. Atenolol (Tenormin)
- B. Prednisone (Deltasone)
- C. Phenelzine (Nardil)
- D. Allopurinol (Zyloprim)
Correct Answer: B
Rationale: The correct answer is B. Prednisone is a corticosteroid that can cause hyperglycemia by increasing glucose production in the liver. Atenolol (Choice A) is a beta-blocker that typically does not affect blood glucose levels significantly. Phenelzine (Choice C) is a monoamine oxidase inhibitor used for depression and does not directly impact blood glucose levels. Allopurinol (Choice D) is a xanthine oxidase inhibitor used to manage gout and does not contribute to hyperglycemia.
