Nursing Elites

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. While assessing a 70-year-old female client with Alzheimer's disease, the nurse notes deep inflamed cracks at the corners of her mouth. What intervention should the nurse include in this client's plan of care?

• A. Apply a moisturizing cream to the affected areas.
• B. Encourage the client to consume foods rich in vitamin B.
• C. Notify the healthcare provider for further evaluation.
• D. Ensure that the client gets adequate B vitamins in foods or supplements.

Correct answer: D

Rationale: Cracks at the corners of the mouth, known as angular cheilitis, can be a sign of vitamin B deficiency, specifically B2 (riboflavin) or B3 (niacin). The nurse should ensure that the client receives adequate B vitamins through foods rich in these nutrients or supplements to address the deficiency, which can help improve the condition of the client's mouth.

3. Why is a low-protein diet recommended for a client with hepatic encephalopathy?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Increased ammonia levels
• D. Electrolyte imbalance

Correct answer: C

Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.

4. 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.

5. A client is receiving chemotherapy and is at risk for neutropenia. Which precaution should the nurse implement?

• A. Encourage regular visitors to boost morale.
• B. Ensure the client receives live vaccines.
• C. Place the client in a private room.
• D. Provide a diet high in fresh fruits and vegetables.

Correct answer: C

Rationale: Placing the client in a private room is crucial to protect them from infections due to their compromised immune system. Neutropenia, a common side effect of chemotherapy, decreases white blood cell count, making the client more susceptible to infections. By placing the client in a private room, exposure to pathogens from other individuals is minimized, reducing the risk of infection and helping maintain the client's health during this vulnerable period.
