Nursing Elites

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 patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

3. A client is being treated with an antidepressant for major depressive disorder. Which statement by the client indicates a need for further teaching?

• A. I know it may take several weeks before I start feeling better.
• B. I should avoid drinking alcohol while taking this medication.
• C. I will stop taking the medication as soon as I feel better.
• D. I should take the medication at the same time every day.

Correct answer: C

Rationale: Choice C indicates a need for further teaching because stopping antidepressants abruptly can lead to withdrawal symptoms. It is essential for the client to follow the healthcare provider's instructions and complete the full course of medication even if they start feeling better to prevent potential relapse or withdrawal effects.

4. A client is receiving chemotherapy and is at risk for neutropenia. Which precaution should the nurse implement?

• A. Encourage regular visitors to boost morale.
• B. Ensure the client receives live vaccines.
• C. Place the client in a private room.
• D. Provide a diet high in fresh fruits and vegetables.

Correct answer: C

Rationale: Placing the client in a private room is crucial to protect them from infections due to their compromised immune system. Neutropenia, a common side effect of chemotherapy, decreases white blood cell count, making the client more susceptible to infections. By placing the client in a private room, exposure to pathogens from other individuals is minimized, reducing the risk of infection and helping maintain the client's health during this vulnerable period.

5. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?

• A. Asterixis.
• B. Jaundice.
• C. Ascites.
• D. Splenomegaly.

Correct answer: A

Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.
