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 client admitted with acute diverticulitis has experienced a sudden increase in temperature and reports a sudden onset of exquisite abdominal tenderness. The nurse's rapid assessment reveals that the client's abdomen is uncharacteristically rigid on palpation. What is the nurse's best response?

• A. Administer a Fleet enema as prescribed and remain with the client
• B. Contact the primary care provider promptly and report these signs of perforation
• C. Position the client supine and insert an NG tube
• D. Page the primary provider and report that the client may be obstructed

Correct answer: B

Rationale: In a client with acute diverticulitis experiencing sudden increase in temperature, exquisite abdominal tenderness, and uncharacteristic abdominal rigidity, these signs suggest a possible perforation. The nurse should promptly contact the primary care provider to report these signs, as perforation requires immediate medical attention to prevent further complications.

4. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.

5. The nurse is caring for a client with a spinal cord injury. Which intervention should the nurse implement to prevent autonomic dysreflexia?

• A. Restrict the client's fluid intake.
• B. Keep the client's room warm.
• C. Ensure the client's bladder is emptied regularly.
• D. Limit the client's intake of high-fiber foods.

Correct answer: C

Rationale: To prevent autonomic dysreflexia in clients with spinal cord injuries, it is crucial to ensure the client's bladder is emptied regularly. Bladder distention is a common trigger for autonomic dysreflexia in these clients. Keeping the bladder empty helps prevent the complications associated with autonomic dysreflexia, such as dangerously high blood pressure. Choices A, B, and D are incorrect. Restricting fluid intake can lead to dehydration, keeping the room warm is not directly related to preventing autonomic dysreflexia, and limiting high-fiber foods is not a primary intervention for this condition.
