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.

A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:
- A. Increase thyroid hormone production
- B. Decrease thyroid hormone production
- C. Relieve symptoms such as tachycardia and anxiety
- D. Prevent weight loss
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.
The client has been diagnosed with primary aldosteronism. Which of the following clinical findings would the nurse expect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypercalcemia
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).
Why is it important to control blood glucose levels in type 2 DM?
- A. Hypertension and kidney disease.
- B. Weight gain and obesity.
- C. Improved wound healing.
- D. Decreased cholesterol levels.
Correct Answer: A
Rationale: Controlling blood glucose levels in type 2 DM is crucial to prevent complications. High blood glucose levels can lead to hypertension and kidney disease, as seen in diabetic nephropathy and diabetic nephropathy. These are common complications of uncontrolled diabetes. Weight gain and obesity (choice B) are influenced by factors such as diet and physical activity rather than blood glucose levels. Improved wound healing (choice C) is not directly related to blood glucose control but can be affected by it indirectly. Decreased cholesterol levels (choice D) are not a direct consequence of high blood glucose levels and are more related to dietary and lifestyle factors.
