Nursing Elites

1. The nurse is caring for a client with a history of adrenal insufficiency. The nurse should monitor for which of the following signs of an Addisonian crisis?

• A. Hypertension
• B. Hyperglycemia
• C. Severe hypotension
• D. Tachycardia

Correct answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

2. A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:

• A. Treat the underlying cause of the disease
• B. Reduce thyroid hormone production
• C. Alleviate symptoms such as tachycardia and tremors
• D. Increase energy levels

Correct answer: C

Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.

3. A nursing student needs to administer potassium chloride intravenously as prescribed to a client with hypokalemia. The nursing instructor determines that the student is unprepared for this procedure if the student states that which of the following is part of the plan for preparation and administration of the potassium?

• A. Obtaining a controlled IV infusion pump
• B. Monitoring urine output during administration
• C. Diluting an appropriate amount of normal saline
• D. Preparing the medication for bolus administration

Correct answer: D

Rationale: The correct answer is preparing the medication for bolus administration (Choice D). Potassium should never be administered as a bolus because it can cause cardiac arrest. It must always be diluted and given slowly. Obtaining a controlled IV infusion pump (Choice A) is essential for accurate delivery, monitoring urine output during administration (Choice B) helps assess the client's response, and diluting an appropriate amount of normal saline (Choice C) is necessary to prevent irritation and ensure safe administration.

4. The nurse is caring for a client with Addison's disease. The client exhibits signs of hypotension, dehydration, and confusion. The nurse should anticipate administering which of the following medications?

• A. Insulin
• B. Hydrocortisone
• C. Levothyroxine
• D. Methimazole

Correct answer: B

Rationale: In Addison's disease, the adrenal glands do not produce enough cortisol. Hydrocortisone is a glucocorticoid medication that is used to replace deficient cortisol levels in patients with Addison's disease. It helps stabilize blood pressure and fluid balance. Insulin (Choice A) is used to manage diabetes, not Addison's disease. Levothyroxine (Choice C) is a thyroid hormone replacement used to treat hypothyroidism, not Addison's disease. Methimazole (Choice D) is used in the treatment of hyperthyroidism, not Addison's disease.

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.
