Nursing Elites

1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

2. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?

• A. White blood cell count
• B. Liver function tests
• C. Kidney function tests
• D. Complete blood count

Correct answer: B

Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.

3. While auscultating a client's heart sounds, which description should the nurse use to document a swishing sound related to blood turbulence or valvular defect?

• A. S1 S2
• B. S1 S2 S3
• C. Murmur
• D. Pericardial friction rub

Correct answer: C

Rationale: The correct answer is 'C: Murmur.' A murmur is auscultated as a swishing sound associated with blood turbulence caused by the heart or a valvular defect. Choices 'A: S1 S2' and 'B: S1 S2 S3' refer to normal heart sounds, specifically the closure of heart valves. 'D: Pericardial friction rub' is a dry, rubbing or grating sound caused by inflammation of the pericardial sac and is not associated with blood flow or valvular issues.

4. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

5. Which statement by the client indicates an understanding of the dietary modifications required with Cushing syndrome?

• A. I should increase my intake of foods high in calcium.
• B. I should avoid foods with high sodium content.
• C. I need to decrease my intake of vitamin D.
• D. I should consume more potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'I should avoid foods with high sodium content.' Clients with Cushing syndrome need to limit their sodium intake to help reduce fluid retention and manage hypertension, which are common complications of the syndrome. Increasing calcium intake (choice A) is not specifically indicated for Cushing syndrome. Decreasing vitamin D intake (choice C) is not a typical dietary modification for this condition. Consuming more potassium-rich foods (choice D) is not a primary focus of dietary modifications for Cushing syndrome.
