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. A client with hyperparathyroidism is being assessed. Which of the following symptoms is the nurse likely to find?

• A. Tetany
• B. Hypocalcemia
• C. Bone pain
• D. Hypotension

Correct answer: C

Rationale: In hyperparathyroidism, there is excessive production of parathyroid hormone, leading to increased calcium resorption from the bones. This process causes bone pain, making choice C the correct answer. Tetany (choice A) is associated with hypocalcemia, not hyperparathyroidism. Hypocalcemia (choice B) is the opposite condition of hyperparathyroidism, where blood calcium levels are elevated. Hypotension (choice D) is not a typical symptom of hyperparathyroidism.

3. A client with hypothyroidism is being treated with levothyroxine. Which of the following symptoms would indicate that the client may be receiving too much medication?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: Tachycardia is a sign of excessive thyroid hormone replacement. Levothyroxine is used to treat hypothyroidism by supplementing thyroid hormone levels. If a client with hypothyroidism experiences symptoms of tachycardia, it suggests that they may be receiving an excessive amount of levothyroxine, causing hyperthyroidism. Bradycardia (Choice A) is more commonly associated with hypothyroidism, not excessive levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also typical symptoms of hypothyroidism and would not typically indicate overmedication.

4. A client with Addison's disease is being educated on managing the condition. Which of the following statements indicates a need for further teaching?

• A. I should carry an emergency kit with hydrocortisone at all times.
• B. I need to increase my sodium intake during hot weather.
• C. I can skip my medication if I feel well.
• D. I should avoid stress as much as possible.

Correct answer: C

Rationale: The correct answer is C. Clients with Addison's disease should not skip their medication, even if they feel well, as consistent medication is necessary to manage the condition. Choice A is correct as carrying an emergency kit with hydrocortisone is essential for managing potential adrenal crises. Choice B is correct as increasing sodium intake during hot weather helps prevent electrolyte imbalances. Choice D is correct as stress can trigger adrenal crisis in individuals with Addison's disease, so stress management is crucial.

5. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?

• A. Serum potassium level
• B. Serum sodium level
• C. Arterial blood gas (ABG) values
• D. Serum osmolarity

Correct answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.
