Nursing Elites

1. A client with hyperthyroidism is being treated with radioactive iodine. The nurse should teach the client to expect which of the following side effects?

• A. Increased heart rate
• B. Hypothyroidism
• C. Hypercalcemia
• D. Weight loss

Correct answer: B

Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.

2. Which of the following statements is true regarding ethical principles and laws?

• A. The government enforces ethics.
• B. Laws establish standards that aid in decision-making.
• C. Ethics are highly specific.
• D. Ethical principles can serve as the foundation for laws.

Correct answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.

3. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

4. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

5. The client has hyperparathyroidism. Which of the following dietary instructions should the nurse provide?

• A. Increase calcium intake
• B. Limit phosphorus intake
• C. Increase fluid intake
• D. Limit vitamin D intake

Correct answer: C

Rationale: The correct answer is to 'Increase fluid intake.' This is because increasing fluid intake helps prevent kidney stones, a common complication of hyperparathyroidism. While calcium is involved in the condition, increasing calcium intake is not recommended as it can exacerbate hypercalcemia, which is commonly present in hyperparathyroidism. Limiting phosphorus intake is not directly related to managing hyperparathyroidism. Limiting vitamin D intake is also not typically necessary in managing hyperparathyroidism, as it is usually a calcium and PTH-related issue.
