1. Which of the following laboratory values should the nurse monitor in a client with Cushing's syndrome?

• A. Blood glucose levels
• B. Serum calcium levels
• C. Serum potassium levels
• D. Serum sodium levels

Correct answer: A

Rationale: The correct answer is A: Blood glucose levels. In Cushing's syndrome, there is excess cortisol in the body which leads to increased blood glucose levels due to its effect on glucose metabolism. Elevated blood glucose levels are a common finding in individuals with Cushing's syndrome. Monitoring blood glucose levels is crucial as it helps in assessing and managing hyperglycemia in these patients. Choice B, serum calcium levels, is not typically a priority in monitoring for Cushing's syndrome. While abnormalities in calcium levels can occur in some endocrine disorders, hypercalcemia is not a hallmark of Cushing's syndrome. Choice C, serum potassium levels, and Choice D, serum sodium levels, are not directly associated with Cushing's syndrome. While electrolyte imbalances can occur in various conditions, they are not specifically linked to Cushing's syndrome as blood glucose levels are.

2. A female client with a history of pheochromocytoma is admitted to the hospital in an acute hypertensive crisis. To reverse the hypertensive crisis caused by pheochromocytoma, nurse Lyka expects to administer:

• A. Phentolamine (Regitine)
• B. Methyldopa (Aldomet)
• C. Mannitol (Osmitrol)
• D. Felodipine (Plendil)

Correct answer: A

Rationale: In a hypertensive crisis due to pheochromocytoma, the appropriate medication to administer is Phentolamine (Regitine), an alpha-adrenergic blocker. Phentolamine acts quickly to block the effects of excess catecholamines that are released in pheochromocytoma, helping to rapidly lower blood pressure. Methyldopa (Aldomet) is an alpha-2 adrenergic agonist used for chronic hypertension, not for acute crises like pheochromocytoma. Mannitol (Osmitrol) is an osmotic diuretic used to reduce intracranial pressure and treat cerebral edema, not indicated for hypertensive crises. Felodipine (Plendil) is a calcium channel blocker used for chronic management of hypertension, not for acute hypertensive crises like those seen in pheochromocytoma.

3. 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.

4. For a male client with hyperglycemia, which assessment finding best supports a nursing diagnosis of Deficient fluid volume?

• A. Cool, clammy skin
• B. Distended neck veins
• C. Increased urine osmolarity
• D. Decreased serum sodium level

Correct answer: C

Rationale: Increased urine osmolarity is the best assessment finding supporting a nursing diagnosis of Deficient fluid volume in a male client with hyperglycemia. In hyperglycemia, there is increased glucose in the blood, which leads to osmotic diuresis. This results in the excretion of large amounts of urine that is concentrated (high osmolarity), leading to dehydration and fluid volume deficit. Cool, clammy skin (Choice A) is more indicative of poor perfusion, distended neck veins (Choice B) are associated with fluid volume excess, and decreased serum sodium level (Choice D) could be a result of dilutional hyponatremia due to fluid overload rather than deficient fluid volume.

5. The nurse is caring for a client with myxedema coma. Which of the following interventions should the nurse prioritize?

• A. Administer intravenous fluids
• B. Provide a warming blanket
• C. Administer levothyroxine intravenously
• D. Place the client in Trendelenburg position

Correct answer: C

Rationale: In myxedema coma, the priority intervention is to administer levothyroxine intravenously. Myxedema coma is a severe form of hypothyroidism, and intravenous levothyroxine is crucial to rapidly replace deficient thyroid hormones. Administering intravenous fluids (choice A) may be necessary, but levothyroxine takes precedence. Providing a warming blanket (choice B) can help maintain the client's body temperature, but it does not address the underlying thyroid hormone deficiency. Placing the client in Trendelenburg position (choice D) is not indicated and can potentially worsen the client's condition.
