A client with hyperthyroidism is being treated with radioactive iodine. The nurse should teach the client to expect which of the following side effects?

Correct Answer: B

Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.

Correct Answer: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

Correct Answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.

Correct Answer: C

Rationale: Cold intolerance is a classic symptom of hypothyroidism. In hypothyroidism, the body's metabolic rate is decreased, leading to a decreased ability to regulate body temperature. This results in a feeling of being cold most of the time. Tachycardia (Choice A) is more commonly associated with hyperthyroidism, not hypothyroidism. Weight loss (Choice B) and diaphoresis (Choice D) are also more characteristic of hyperthyroidism, where there is an increased metabolic rate and excess heat production.

Correct Answer: A

Rationale: In hyperparathyroidism, there are already elevated calcium levels in the body. Therefore, clients should avoid high-calcium foods like milk to prevent further increase in calcium levels. Bananas, spinach, and processed meats do not have significant calcium content and do not need to be avoided specifically in hyperparathyroidism.
