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.

The client with hyperthyroidism is receiving propylthiouracil (PTU). The nurse should monitor for which of the following potential side effects?
- A. Leukopenia
- B. Hyperglycemia
- C. Hypertension
- D. Weight gain
Correct Answer: A
Rationale: The correct answer is A: Leukopenia. Propylthiouracil can lead to bone marrow suppression, resulting in leukopenia. Monitoring white blood cell counts is crucial to detect this potential side effect early. Choice B, hyperglycemia, is not typically associated with propylthiouracil use. Choice C, hypertension, is not a common side effect of propylthiouracil. Choice D, weight gain, is also not a typical side effect of propylthiouracil therapy.
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 Addison's disease is experiencing an Addisonian crisis. The nurse should expect to administer which of the following medication?
- A. Insulin
- B. Hydrocortisone
- C. Levothyroxine
- D. Methimazole
Correct Answer: B
Rationale: During an Addisonian crisis, the adrenal glands are not producing enough cortisol, leading to a life-threatening situation. Hydrocortisone, a glucocorticoid, is the medication of choice in managing an Addisonian crisis. It helps replace deficient cortisol levels, stabilize blood pressure, and prevent further complications. Insulin (Choice A) is not indicated in Addison's disease unless specifically needed for diabetes management. Levothyroxine (Choice C) is used in hypothyroidism, not in Addison's disease. Methimazole (Choice D) is used to manage hyperthyroidism, which is not related to Addison's disease or its crisis.
A client is admitted to the ER with DKA. In the acute phase, the priority nursing action is to prepare to:
- A. Administer regular insulin intravenously
- B. Administer 5% dextrose intravenously
- C. Correct the acidosis
- D. Apply an electrocardiogram monitor
Correct Answer: A
Rationale: Administering regular insulin intravenously is the priority nursing action in the acute phase of DKA. Insulin helps to lower blood glucose levels by promoting cellular uptake of glucose and inhibiting ketone production. Administering dextrose would be counterproductive as it can worsen hyperglycemia. Correcting acidosis is important but usually follows insulin administration. Applying an electrocardiogram monitor is not the priority action in the acute management of DKA.
A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a potassium level of 5.5 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a potassium value at this level?
- A. The client with colitis
- B. The client with Cushing's syndrome
- C. The client who has been overusing laxatives
- D. The client who has sustained a traumatic burn
Correct Answer: D
Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.
