Correct Answer: B

Rationale: Primary aldosteronism involves the overproduction of aldosterone by the adrenal glands. Aldosterone increases potassium excretion, leading to hypokalemia. Therefore, in primary aldosteronism, the nurse would expect to find hypokalemia, not hyperkalemia (choice A), hyponatremia (choice C), or hypercalcemia (choice D).

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.

Correct Answer: C

Rationale: Clients with hyperparathyroidism should avoid high-calcium foods like milk because they already have elevated calcium levels. Bananas and spinach are not high in calcium and can be included in the diet. Processed meats are not specifically contraindicated in hyperparathyroidism, so they are not the correct answer.

Correct Answer: D

Rationale: The correct answer is D: Planning for the future. In this scenario, the nurse manager is engaging in decisional activities related to planning for the future. This involves analyzing potential impacts of policy changes and community shifts on the unit's functioning and making decisions based on predictions and foresight. Option A, resource allocation, focuses on distributing resources effectively. Option B, monitoring, involves observing and assessing current activities. Option C, job analysis and redesign, pertains to evaluating and restructuring roles and responsibilities within the unit, which is not the primary focus of the scenario provided.

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.
