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. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation in the water seal chamber.
• D. Steady bubbling in the suction control chamber.

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.

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. What is the primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT)?

• A. No need for regular INR monitoring
• B. Lower risk of bleeding
• C. Fewer dietary restrictions
• D. Longer half-life

Correct answer: A

Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.

5. Why is a low-protein diet recommended for a patient with renal failure?

• A. To prevent fluid overload
• B. To reduce nitrogenous waste
• C. To maintain electrolyte balance
• D. To prevent hyperglycemia

Correct answer: B

Rationale: A low-protein diet is crucial for patients with renal failure to reduce the generation of nitrogenous waste products like urea and creatinine, which the compromised kidneys struggle to eliminate effectively. By limiting protein intake, the production of these waste products is decreased, lessening the burden on the kidneys and helping to manage the progression of renal failure. Choices A, C, and D are incorrect because a low-protein diet primarily aims to reduce the workload on the kidneys by decreasing the production of nitrogenous waste, not to prevent fluid overload, maintain electrolyte balance, or prevent hyperglycemia.
