Nursing Elites

1. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.

2. Nurse Louie is developing a teaching plan for a male client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus?

• A. Antidiuretic hormone (ADH)
• B. Thyroid-stimulating hormone (TSH)
• C. Follicle-stimulating hormone (FSH)
• D. Luteinizing hormone (LH)

Correct answer: A

Rationale: Diabetes insipidus is a condition characterized by a deficiency of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water balance by controlling the amount of water reabsorbed by the kidneys. Options B, C, and D are incorrect as they are not associated with diabetes insipidus. TSH (thyroid-stimulating hormone) is responsible for regulating thyroid function, while FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in reproductive functions.

3. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

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

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

4. The client with hypothyroidism is being educated by the healthcare provider about taking levothyroxine. Which of the following instructions should be included?

• A. Take the medication with meals
• B. Take the medication at bedtime
• C. Take the medication on an empty stomach in the morning
• D. Take the medication with a glass of milk

Correct answer: C

Rationale: The correct answer is to take levothyroxine on an empty stomach in the morning. This instruction is essential to enhance absorption and efficacy of the medication. Taking levothyroxine with meals, at bedtime, or with a glass of milk can interfere with its absorption and effectiveness, leading to suboptimal treatment outcomes.

5. In a 29-year-old female client who is being successfully treated for Cushing's syndrome, nurse Lyzette would expect a decline in:

• A. Serum glucose level.
• B. Hair loss.
• C. Bone mineralization.
• D. Menstrual flow.

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's syndrome, there is excess cortisol production which can lead to hyperglycemia. Successful treatment of Cushing's syndrome aims to normalize cortisol levels, resulting in a decline in serum glucose levels. Choice B, hair loss, is not specifically associated with Cushing's syndrome or its treatment. Choice C, bone mineralization, is often compromised in Cushing's syndrome due to the effects of excess cortisol on bones; however, successful treatment would aim to improve bone health rather than decline it. Choice D, menstrual flow, is not directly linked to Cushing's syndrome or its treatment, so a decline in menstrual flow would not be an expected outcome of successful treatment.
