Nursing Elites

1. A client with type 1 DM calls the nurse to report recurrent episodes of hypoglycemia with exercise. Which statement by the client indicates an inadequate understanding of the peak action of NPH insulin and exercise?

• A. The best time for me to exercise is every afternoon.
• B. The best time for me to exercise is right after I eat.
• C. The best time for me to exercise is after breakfast.
• D. The best time for me to exercise is after my morning snack.

Correct answer: A

Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.

2. The client with 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: The correct answer is A: Increased risk of heart disease and stroke. Uncontrolled blood glucose levels in clients with diabetes mellitus (DM) can lead to cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, increasing the risk of atherosclerosis and cardiovascular events. Choices B, C, and D are incorrect because uncontrolled blood glucose levels do not improve wound healing, reduce the need for medication, or decrease the risk of infection. In fact, uncontrolled blood glucose levels can impair wound healing, require more medications to manage symptoms, and increase the risk of infections due to compromised immune function.

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. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.
