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 70-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Gallstones
• B. Hepatitis
• C. Pancreatic cancer
• D. Primary biliary cirrhosis

Correct answer: C

Rationale: The presentation of a 70-year-old man with weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels is highly suggestive of pancreatic cancer. This clinical scenario, known as Courvoisier's sign, points towards a pancreatic malignancy due to biliary obstruction. Gallstones could cause similar symptoms but would typically not present with a palpable mass. Hepatitis usually does not present with a palpable mass and would have different laboratory findings. Primary biliary cirrhosis typically presents differently with chronic cholestasis without the presence of a palpable mass or a pancreatic lesion.

3. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

4. A client with osteoporosis is being discharged home. Which instruction should the nurse include in the discharge teaching?

• A. Avoid weight-bearing exercises.
• B. Take calcium supplements with meals.
• C. Limit vitamin D intake.
• D. Increase intake of caffeine-containing beverages.

Correct answer: B

Rationale: Taking calcium supplements with meals is a crucial instruction for a client with osteoporosis. Calcium absorption is enhanced when taken with food, and proper calcium intake is essential for managing osteoporosis effectively by promoting bone health and density. Avoiding weight-bearing exercises (Choice A) is incorrect because these exercises help improve bone strength. Limiting vitamin D intake (Choice C) is also incorrect as vitamin D is necessary for calcium absorption. Increasing caffeine intake (Choice D) is not recommended as caffeine can interfere with calcium absorption.

5. A client who participates in a health maintenance organization (HMO) needs a bone marrow transplant for the treatment of breast cancer. The client tells the nurse that she is concerned that her HMO may deny her claim. What action by the nurse best addresses the client's need at this time?

• A. Have the client's healthcare provider write a letter to the HMO explaining the need for the transplant.
• B. Help the client place a call to the HMO to seek information about limitations of coverage.
• C. Encourage the client to contact a lawyer to file a lawsuit against the HMO if necessary.
• D. Have the social worker contact the state board of insurance to register a complaint against the HMO.

Correct answer: B

Rationale: The best action for the nurse to take in this situation is to help the client directly contact the HMO to seek information about limitations of coverage. This approach addresses the client's immediate concerns and clarifies the situation, enabling the client to understand the coverage and potential outcomes regarding the bone marrow transplant. Choice A is not the best option as having the healthcare provider write a letter may not provide immediate clarification on coverage. Choice C is inappropriate as legal action should be considered as a last resort, and choice D involving the state board of insurance is not necessary at this initial stage of addressing the client's concern.
