Nursing Elites

1. The client with DM is being taught about the signs of hyperglycemia. Which symptom should the nurse include?

• A. Excessive thirst
• B. Sweating
• C. Shaking
• D. Hunger

Correct answer: A

Rationale: Excessive thirst, also known as polydipsia, is a hallmark symptom of hyperglycemia. When blood glucose levels are high, the body tries to eliminate the excess glucose through urine, leading to increased urination and subsequent thirst. Sweating, shaking, and hunger are more commonly associated with hypoglycemia, not hyperglycemia. Sweating can occur when blood sugar levels drop too low, shaking is a sign of hypoglycemia, and hunger is often a result of low blood sugar levels triggering the body to seek fuel.

2. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.

3. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

• A. U waves
• B. Absent P waves
• C. Elevated T waves
• D. Elevated ST segment

Correct answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

4. A client with hypothyroidism is prescribed levothyroxine. The nurse should teach the client to take this medication:

• A. With meals
• B. Before bedtime
• C. On an empty stomach in the morning
• D. With a glass of milk

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.

5. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor for which of the following potential side effects?

• A. Hypoglycemia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hyponatremia

Correct answer: C

Rationale: The correct answer is C, Hyperglycemia. Corticosteroid therapy can lead to hyperglycemia by increasing blood glucose levels. Corticosteroids can induce insulin resistance, decrease glucose uptake by tissues, and promote gluconeogenesis. While corticosteroid therapy can cause hypoglycemia in some cases, it is more commonly associated with hyperglycemia. Hyperkalemia (choice B) is more commonly associated with conditions like renal failure or certain medications. Hyponatremia (choice D) is typically not a common side effect of corticosteroid therapy unless there are other contributing factors present.
