Nursing Elites

1. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

2. A patient with hyperlipidemia is prescribed atorvastatin. What lab test should be monitored periodically to assess for adverse effects?

• A. Liver function tests
• B. Complete blood count
• C. Blood glucose levels
• D. Serum potassium

Correct answer: A

Rationale: The correct answer is A: Liver function tests. Patients on atorvastatin should have their liver function tests monitored periodically to detect any potential liver damage. Atorvastatin, a statin medication used to lower cholesterol levels, can rarely cause liver enzyme abnormalities, so regular monitoring is essential to identify any adverse effects early on. Monitoring the complete blood count (choice B), blood glucose levels (choice C), or serum potassium (choice D) is not typically required specifically for atorvastatin therapy. While these tests may be important for other conditions or medications, liver function tests are the most relevant for monitoring the adverse effects of atorvastatin.

3. A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: Patients prescribed methotrexate should be advised to take folic acid supplements as prescribed. Methotrexate can deplete folic acid levels, leading to side effects. By taking folic acid supplements as directed, the patient can reduce the risk of experiencing adverse effects associated with methotrexate therapy. It is important to note that the effects of methotrexate may not be immediate, so realistic expectations should be set with the patient. Alcohol should be avoided while taking methotrexate due to potential interactions and increased risk of liver toxicity. There is no specific recommendation to limit fluid intake to 1 liter per day in relation to methotrexate therapy.

4. A 56-year-old white male complains of intermittent dysphagia for the past three months, particularly with the ingestion of meat. He has no difficulties swallowing liquids. He has no history of smoking, uses no medications, and has had no weight loss. What test would be best to evaluate him?

• A. Upper endoscopy
• B. Chest/abdominal CT scan
• C. Barium swallow
• D. Esophageal manometry

Correct answer: C

Rationale: For a patient presenting with intermittent dysphagia, especially with solids like meat, a barium swallow is the most appropriate initial test. In this case, the classic presentation suggests a Schatzki’s ring, which is best visualized through a barium study. Upper endoscopy may not always visualize Schatzki’s rings effectively. Chest/abdominal CT scan and esophageal manometry are not the preferred tests for diagnosing Schatzki’s rings. Treatment for Schatzki’s rings often involves bougie dilatation, and no further therapy may be necessary.

5. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.
