1. 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.
2. A client with heart failure is receiving digoxin (Lanoxin). Which finding indicates that the medication is effective?
- A. Increased heart rate.
- B. Decreased pedal edema.
- C. Elevated blood pressure.
- D. Improved urine output.
Correct answer: B
Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.
3. 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.
4. A client in acute renal failure has a serum potassium level of 6.3 mEq/L. What intervention can the nurse expect the healthcare provider to prescribe?
- A. Nitrofurantoin (Macrodantin) orally.
- B. Erythropoietin (Epogen) intravenously.
- C. Kayexalate retention enema.
- D. Azathioprine (Imuran) orally.
Correct answer: C
Rationale: In acute renal failure with high serum potassium levels, the healthcare provider is likely to prescribe a Kayexalate retention enema. Kayexalate is a medication used to lower elevated potassium levels by promoting potassium excretion through the gastrointestinal tract, thus aiding in the management of hyperkalemia in clients with renal failure.
5. The healthcare provider is caring for a client who has just undergone a thyroidectomy. Which assessment finding requires immediate intervention?
- A. Hoarse voice.
- B. Difficulty swallowing.
- C. Numbness and tingling around the mouth.
- D. Sore throat.
Correct answer: C
Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a potential complication after thyroidectomy. Hypocalcemia can occur due to inadvertent injury or removal of the parathyroid glands during the thyroidectomy, leading to decreased calcium levels. As a result, the client may experience symptoms such as numbness, tingling, muscle cramps, or spasms. Prompt intervention is necessary to prevent severe complications like tetany or seizures. Therefore, the healthcare provider should address numbness and tingling around the mouth immediately to prevent further deterioration of calcium levels and potential serious outcomes. Choices A, B, and D are not typically associated with immediate post-thyroidectomy complications and can be addressed after ensuring the client's calcium levels are stable.
