Nursing Elites

1. Which of the following statements should be included in the teaching to a client about a do-not-resuscitate order (DNR)?

• A. When a heart ceases to beat, the client is pronounced clinically dead.
• B. Physicians are required to write DNR orders.
• C. A DNR order can be written after discussion with the client and family.
• D. A court decision is needed for a DNR.

Correct answer: C

Rationale: The correct statement to include in teaching a client about a do-not-resuscitate (DNR) order is that it can be written after discussion with the client and family. This involves ensuring that the client and their family understand the implications and make an informed decision. Choice A is incorrect as pronouncing clinical death is not directly related to discussing a DNR order. Choice B is incorrect as while physicians typically write DNR orders, it is not a strict requirement. Choice D is incorrect as a court decision is not typically required for a DNR order; it is a decision made by the client with input from healthcare providers and family members.

2. A client with Addison's disease is at risk for which of the following complications?

• A. Hypertension
• B. Hypovolemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: B

Rationale: A client with Addison's disease is at risk for hypovolemia. Addison's disease is characterized by adrenal insufficiency, particularly cortisol and aldosterone deficiency. Aldosterone deficiency leads to impaired sodium and water retention, resulting in decreased blood volume and hypovolemia. This condition can cause hypotension, not hypertension (Choice A), as reduced blood volume leads to decreased pressure. Hypernatremia (Choice C) is unlikely in Addison's disease because of the loss of sodium along with water in hypovolemia. Hypokalemia (Choice D) can occur due to aldosterone deficiency, but it is not the primary complication associated with Addison's disease.

3. A client with hypoparathyroidism is at risk for which of the following complications?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: Hypoparathyroidism is characterized by decreased levels of parathyroid hormone, leading to reduced calcium levels in the blood, which results in hypocalcemia. Therefore, the correct answer is B. Choices A, C, and D are incorrect because hypoparathyroidism does not typically lead to hypercalcemia, hyperkalemia, or hypernatremia. Hypercalcemia is more commonly associated with hyperparathyroidism, where there is excess secretion of parathyroid hormone.

4. 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.

5. A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.
