Nursing Elites

1. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.

2. Acarbose (Precose), an alpha-glucosidase inhibitor, is prescribed for a female client with type 2 diabetes mellitus. During discharge planning, nurse Pauleen would be aware of the client's need for additional teaching when the client states:

• A. If I have hypoglycemia, I should eat some sugar, not dextrose.
• B. The drug makes my pancreas release more insulin.
• C. I should never take insulin while I'm taking this drug.
• D. It's best if I take the drug with the first bite of a meal.

Correct answer: B

Rationale: The correct answer is B. Acarbose (Precose) is an alpha-glucosidase inhibitor that works by slowing carbohydrate absorption in the intestine, not by stimulating insulin release. Therefore, the client would need additional teaching if they state that the drug makes their pancreas release more insulin (Choice B). Choices A, C, and D are incorrect. Choice A is incorrect because during hypoglycemia, it is recommended to consume glucose or dextrose to rapidly raise blood sugar levels. Choice C is incorrect because insulin therapy may still be needed in some cases, even when taking acarbose. Choice D is incorrect because acarbose should be taken at the start of a meal to help reduce postprandial blood glucose levels.

3. The nurse is caring for a client with myxedema coma. Which of the following interventions should the nurse prioritize?

• A. Administer intravenous fluids
• B. Provide a warming blanket
• C. Administer levothyroxine intravenously
• D. Place the client in Trendelenburg position

Correct answer: C

Rationale: In myxedema coma, the priority intervention is to administer levothyroxine intravenously. Myxedema coma is a severe form of hypothyroidism, and intravenous levothyroxine is crucial to rapidly replace deficient thyroid hormones. Administering intravenous fluids (choice A) may be necessary, but levothyroxine takes precedence. Providing a warming blanket (choice B) can help maintain the client's body temperature, but it does not address the underlying thyroid hormone deficiency. Placing the client in Trendelenburg position (choice D) is not indicated and can potentially worsen the client's condition.

4. An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting:

• A. 2 to 5 g of a simple carbohydrate.
• B. 10 to 15 g of a simple carbohydrate.
• C. 18 to 20 g of a simple carbohydrate.
• D. 25 to 30 g of a simple carbohydrate.

Correct answer: B

Rationale: The correct answer is B: 10 to 15 g of a simple carbohydrate. In the treatment of hypoglycemia, it is important to administer a specific amount of simple carbohydrates to raise blood glucose levels effectively without causing hyperglycemia. 10 to 15 g of simple carbohydrates, such as glucose tablets, fruit juice, or regular soft drinks, is recommended to rapidly increase blood sugar levels in clients experiencing hypoglycemia. Choices A, C, and D are incorrect as they either provide too little or too much glucose, which may not effectively treat the hypoglycemic episode or may lead to rebound hyperglycemia.

5. 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.
