Correct Answer: B

Rationale: The correct answer is B. Clients with type 2 diabetes mellitus should not stop taking their medication even if blood sugar levels are normal. This is because ongoing management is necessary to control blood sugar levels and prevent complications. Choice A is correct as rotating injection sites helps prevent skin damage and improves insulin absorption. Choice C is correct as regular monitoring of blood sugar levels is vital for managing diabetes effectively. Choice D is correct as following a healthy diet and exercising regularly are key components of diabetes management.

Correct Answer: B

Rationale: The correct answer is B: Propylthiouracil. Propylthiouracil is an antithyroid medication used to manage hyperthyroidism by inhibiting the synthesis of thyroid hormones. Levothyroxine (Choice A) is typically used to treat hypothyroidism, the opposite of hyperthyroidism. Lithium (Choice C) is not used to treat hyperthyroidism but is commonly used to manage bipolar disorder. Metoprolol (Choice D) is a beta-blocker that may be used to manage symptoms like tachycardia associated with hyperthyroidism, but it is not the primary treatment for the condition.

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.

Correct Answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.
