Nursing Elites

1. 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.

2. A client with type 2 DM is being taught about the importance of foot care. Which instruction should the nurse include?

• A. Wear comfortable shoes that allow air circulation.
• B. Walk barefoot whenever possible.
• C. Use a heating pad to warm your feet.
• D. Soak your feet in hot water every night.

Correct answer: A

Rationale: The correct instruction for a client with type 2 diabetes mellitus (DM) regarding foot care is to wear comfortable shoes that allow air circulation. This recommendation helps prevent foot injuries and infections, which are common concerns for individuals with diabetes. Choice B, walking barefoot, can increase the risk of injuries and wounds due to reduced sensation in the feet often seen in diabetes. Choice C, using a heating pad, can lead to burns or skin damage if the temperature is not carefully monitored, making it an unsafe practice. Choice D, soaking feet in hot water every night, can also be harmful as it can cause burns and dry out the skin, leading to further complications for individuals with diabetes. Therefore, the most appropriate and safe advice is to wear comfortable shoes that promote air circulation to maintain foot health and prevent complications.

3. When instructing the female client diagnosed with hyperparathyroidism about diet, Nurse Gina should stress the importance of which of the following?

• A. Restricting fluids
• B. Restricting sodium
• C. Forcing fluids
• D. Restricting potassium

Correct answer: C

Rationale: The correct answer is C: Forcing fluids. Nurse Gina should stress the importance of forcing fluids to help prevent kidney stones and hypercalcemia in clients with hyperparathyroidism. Restricting fluids (choice A) is not recommended as dehydration can worsen the condition. Restricting sodium (choice B) is not directly related to the management of hyperparathyroidism. Restricting potassium (choice D) is not typically necessary in hyperparathyroidism unless hyperkalemia is present.

4. After undergoing a subtotal thyroidectomy, a female client develops hypothyroidism. Dr. Smith prescribes levothyroxine (Levothroid), 25 mcg P.O. daily. For which condition is levothyroxine the preferred agent?

• A. Primary hypothyroidism
• B. Graves' disease
• C. Thyrotoxicosis
• D. Euthyroidism

Correct answer: A

Rationale: Levothyroxine is the preferred agent for primary hypothyroidism because it provides the necessary replacement of thyroid hormone in patients with deficient thyroid function. Choice B, Graves' disease, is an autoimmune disorder that causes hyperthyroidism and is typically treated with antithyroid medications or radioactive iodine. Choice C, thyrotoxicosis, refers to the clinical state resulting from excessive thyroid hormone action and is not typically treated with levothyroxine. Choice D, euthyroidism, describes a normal thyroid function and would not require treatment with levothyroxine.

5. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.
