Nursing Elites

1. 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.

2. When should a new nurse graduate consider applying for a position as a nurse manager?

• A. When she is comfortable in her current position
• B. When she begins mentoring other new nurses
• C. As soon as a position opens
• D. When she has developed leadership and clinical expertise

Correct answer: D

Rationale: A new nurse graduate should consider applying for a nurse manager position when they have developed both leadership and clinical expertise. This ensures that they are well-prepared for the responsibilities of the role. Choice A is incorrect because being comfortable in the current position does not necessarily equate to having the required skills for a nurse manager role. Choice B is incorrect as mentoring other new nurses, while valuable, may not directly align with the skills needed for a managerial position. Choice C is incorrect as applying for a nurse manager position solely because a position is available does not guarantee readiness for the role.

3. A healthcare professional is preparing to care for a client with a potassium deficit. The healthcare professional reviews the client's record and determines that the client was at risk for developing the potassium deficit because the client:

• A. Has renal failure.
• B. Requires nasogastric suction.
• C. Has a history of Addison's disease.
• D. Is taking a potassium-sparing diuretic.

Correct answer: B

Rationale: Nasogastric suction can lead to significant potassium loss due to the continuous drainage of gastric contents, increasing the risk of a potassium deficit. Choices A, C, and D do not directly result in the significant loss of potassium. Renal failure may lead to potassium retention rather than a deficit. Addison's disease is associated with adrenal insufficiency, not potassium depletion. Potassium-sparing diuretics, as the name suggests, typically help retain potassium rather than cause a deficit.

4. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical manifestations should the nurse expect?

• A. Hypernatremia
• B. Hypotension
• C. Decreased urine output
• D. Polyuria

Correct answer: C

Rationale: The correct answer is C: 'Decreased urine output.' Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone, leading to water retention and decreased urine output. Therefore, the nurse should expect the client to have decreased urine output. Choices A, B, and D are incorrect. Hypernatremia (Choice A) is not typically associated with SIADH as it usually leads to dilutional hyponatremia. Hypotension (Choice B) is not a common clinical manifestation of SIADH. Polyuria (Choice D) is the opposite of what is expected in a client with SIADH, who typically presents with decreased urine output.

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.
