1. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

2. Which signs or symptoms are characteristic of an adult client diagnosed with Cushing's syndrome?

• A. Husky voice and complaints of hoarseness.
• B. Warm, soft, moist, salmon-colored skin.
• C. Visible swelling of the neck, with no pain.
• D. Central-type obesity, with thin extremities.

Correct answer: D

Rationale: Cushing's syndrome is characterized by central-type obesity with thin extremities, often referred to as 'truncal obesity.' This pattern of weight distribution is a key feature of Cushing's syndrome due to excessive cortisol levels, leading to fat accumulation in the face, neck, and abdomen, while the extremities remain relatively thin. The other options listed, such as husky voice, hoarseness, warm, soft, moist, salmon-colored skin, and visible swelling of the neck, are not typical findings associated with Cushing's syndrome.

3. Which of the following statements is true about ischemic colitis?

• A. Typically requires colonic resection
• B. Affects the watershed areas of the colon, namely, the splenic flexure, right colon, and rectum
• C. Is only seen in the elderly
• D. Requires colonoscopic intervention

Correct answer: B

Rationale: Ischemic colitis most often results from low-flow states associated with hypotension or poor perfusion. As a result, the vascular watershed areas of the colon, including the splenic flexure, right colon, and rectum, are at highest risk of ischemic injury. Therefore, option B is correct as it accurately identifies the areas commonly affected by ischemic colitis.

4. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

5. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?

• A. In most cases, breast cancer is not caused by the BRCA gene.
• B. It depends on how you will feel if the test is positive for the BRCA gene.
• C. There are many things to consider before deciding to have genetic testing.
• D. You should decide first whether you are willing to have a bilateral mastectomy.

Correct answer: C

Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.
