Nursing Elites

1. A client with hyperthyroidism is receiving radioactive iodine therapy. The nurse should monitor for which of the following side effects?

• A. Hypothyroidism
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypothyroidism. Radioactive iodine therapy is used to treat hyperthyroidism by destroying thyroid tissue and reducing hormone production. This can lead to an underactive thyroid, resulting in hypothyroidism. Hyperkalemia (choice B) is an elevated potassium level, usually not associated with radioactive iodine therapy. Hyponatremia (choice C) is a low sodium level, which is also not a common side effect of this therapy. Hypercalcemia (choice D) is an elevated calcium level, unrelated to radioactive iodine therapy for hyperthyroidism.

2. A client with terminal pancreatic cancer asks questions about a do not resuscitate order. Which of the following statements should be included in the RN's teaching to the client?

• A. When a heart ceases to beat, the client is pronounced clinically dead.
• B. Physicians must write do not resuscitate (DNR) orders.
• C. A DNR order can be written after the healthcare provider has discussed it with the client and family.
• D. A DNR requires a court decision.

Correct answer: C

Rationale: A DNR order is typically written after the healthcare provider has discussed the implications with the patient and their family. This ensures that the patient and family are fully informed before making such a critical decision. Choice A is incorrect because pronouncing clinical death is a medical determination, not directly related to DNR orders. Choice B is incorrect because while physicians commonly write DNR orders, the discussion with the patient and family is crucial. Choice D is incorrect because a DNR order does not require a court decision; it is a decision made in collaboration with the healthcare team and the patient or family.

3. The healthcare provider is monitoring a client with Cushing's syndrome. Which of the following findings should the healthcare provider report?

• A. Hypotension
• B. Hyperglycemia
• C. Weight loss
• D. Hypokalemia

Correct answer: B

Rationale: In Cushing's syndrome, hyperglycemia is a common finding due to increased cortisol levels leading to insulin resistance. This can have serious implications such as diabetes mellitus and should be promptly reported for appropriate management. Hypotension (choice A) is more commonly associated with Addison's disease, not Cushing's syndrome. Weight gain rather than weight loss (choice C) is typically observed in clients with Cushing's syndrome. While hypokalemia (choice D) can occur in Cushing's syndrome due to excess cortisol affecting potassium levels, it is not as critical as hyperglycemia and may not be the priority for immediate reporting.

4. 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.

5. A client with DM asks a nurse why it is necessary to rotate injection sites when using an insulin pen. The nurse's best response would be:

• A. To prevent scar tissue from forming under the skin.
• B. To make the injections less painful.
• C. To help the insulin absorb better.
• D. To keep the skin looking healthy.

Correct answer: C

Rationale: The correct answer is C: "To help the insulin absorb better." Rotating injection sites is important as it helps to ensure better insulin absorption and reduces the risk of developing lipodystrophy. Option A is incorrect as rotating sites primarily aims to optimize insulin absorption, not prevent scar tissue. Option B is inaccurate because rotating injection sites does not necessarily make the injections less painful. Option D is incorrect as the primary reason for rotating injection sites is not related to the aesthetics of the skin but rather to enhance insulin absorption and prevent complications.
