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 with a diagnosis of rheumatoid arthritis is experiencing severe pain. Which medication is likely to be prescribed?

• A. Acetaminophen (Tylenol)
• B. Ibuprofen (Advil)
• C. Methotrexate (Rheumatrex)
• D. Prednisone (Deltasone)

Correct answer: C

Rationale: Methotrexate is commonly prescribed for rheumatoid arthritis to reduce inflammation and slow disease progression. It is a disease-modifying antirheumatic drug (DMARD) that helps control symptoms and prevent joint damage in individuals with rheumatoid arthritis. While acetaminophen and ibuprofen are used for pain relief, they are not typically prescribed to address the underlying inflammation and disease progression associated with rheumatoid arthritis. Prednisone may be used for short-term symptom relief or during disease flares, but it is not a first-line treatment for rheumatoid arthritis.

4. A client who is acutely ill has vigilant oral care included in their plan of care. What factor increases this client's risk for dental caries?

• A. Hormonal changes induced by the stress response leading to an acidic oral environment
• B. Systemic infections commonly affecting the teeth
• C. Intravenous hydration lacking fluoride
• D. Inadequate nutrition and reduced saliva production contributing to cavities

Correct answer: D

Rationale: Inadequate nutrition and decreased saliva production can lead to a conducive environment for the development of dental caries. Without proper nutrition and sufficient saliva, the protective mechanisms against cavities are compromised, making the individual more susceptible to tooth decay.

5. When providing dietary instructions to a client with cirrhosis, which dietary restriction is important for the nurse to emphasize?

• A. Low-protein diet
• B. Low-sodium diet
• C. High-fiber diet
• D. High-calcium diet

Correct answer: B

Rationale: A low-sodium diet is crucial for clients with cirrhosis to manage fluid retention and ascites. Excessive sodium intake can worsen fluid accumulation in the body, leading to complications. By restricting sodium intake, the client can help reduce fluid retention and maintain better overall health. Therefore, emphasizing a low-sodium diet is essential in the dietary management of cirrhosis. Choices A, C, and D are not the primary focus for cirrhosis management. While protein restriction may be necessary in advanced stages of liver disease, it is not the main dietary concern in cirrhosis. High-fiber and high-calcium diets are generally beneficial for overall health but are not specifically emphasized in cirrhosis management.
