1. Which lab value is essential for a patient receiving warfarin therapy?

Correct answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

2. A nurse in a mental health facility receives a change of shift report on four clients. Which of the following clients should the nurse plan to assess first?

Correct answer: A

Rationale: The nurse should plan to assess the client placed in restraints due to aggressive behavior first. Clients in restraints require immediate attention and frequent monitoring for safety. While weight loss, medication administration, and ECT treatment are important, the client in restraints is in a critical situation that requires immediate assessment and intervention.

3. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be elevated?

Correct answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.

4. How should a healthcare professional monitor a patient with a central line for infection?

Correct answer: A

Rationale: Monitoring the dressing site daily is crucial for detecting early signs of infection in patients with central lines. Checking for redness and swelling (choice B) is important but may indicate a more advanced stage of infection. Monitoring for fever (choice C) can also be a sign of infection, but it is a later manifestation. Flushing the central line (choice D) is necessary for maintaining patency but does not directly monitor for infection.

5. What is the most appropriate nursing intervention for a patient experiencing hypoglycemia?

Correct answer: B

Rationale: The most appropriate nursing intervention for a patient experiencing hypoglycemia is to administer oral glucose. Oral glucose is usually sufficient for treating mild hypoglycemia and can be administered quickly and easily. Administering IV glucose (Choice A) is reserved for severe cases where the patient is unable to swallow or unconscious. Checking blood sugar in 15 minutes (Choice C) is important but providing glucose should come first. Providing a high-calorie snack (Choice D) may not be as rapidly effective as administering oral glucose in quickly raising blood sugar levels in a patient experiencing hypoglycemia.
