Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

2. A client with a urinary tract infection is prescribed ciprofloxacin. What is the most important teaching the nurse should provide?

• A. Take the medication with milk to prevent stomach upset.
• B. Increase fluid intake to 2-3 liters per day.
• C. Avoid taking the medication with dairy products.
• D. Continue taking the medication even if symptoms improve.

Correct answer: B

Rationale: Ciprofloxacin can cause crystalluria, so increasing fluid intake to 2-3 liters per day helps flush out the medication and prevent crystal formation in the kidneys. This also ensures adequate hydration, which supports the body's ability to fight the infection. Choice A is incorrect because ciprofloxacin should not be taken with dairy products as they can interfere with the absorption of the medication. Choice D is incorrect because although it's important to complete the full course of antibiotics, it's equally crucial to report any improvement in symptoms to the healthcare provider.

3. A client with Parkinson's disease is prescribed levodopa/carbidopa. The nurse instructs the client to take the medication with meals. Which rationale should the nurse provide for taking the medication with food?

• A. It enhances the effectiveness of the medication
• B. It helps to improve absorption
• C. It prevents orthostatic hypotension
• D. It reduces gastrointestinal upset

Correct answer: D

Rationale: The correct answer is D: 'It reduces gastrointestinal upset.' Levodopa/carbidopa can cause nausea and other gastrointestinal side effects. Taking the medication with food can help reduce these side effects and improve the client's comfort. Choices A, B, and C are incorrect because taking the medication with food does not primarily enhance effectiveness, improve absorption, or prevent orthostatic hypotension. The main reason for advising to take the medication with meals is to minimize gastrointestinal upset.

4. A client is experiencing angina at rest. Which statement indicates a good understanding of the care required?

• A. I will notify the nurse if my chest pain is not relieved in 30 minutes.
• B. I will use nitroglycerin as needed, every 5 minutes, up to 3 doses.
• C. I will avoid physical activity until the pain subsides completely.
• D. I will take nitroglycerin 30 minutes before any physical activity.

Correct answer: B

Rationale: The correct answer is B. Using nitroglycerin as needed, every 5 minutes, up to 3 doses, is the appropriate management for angina at rest. This helps dilate blood vessels, improving blood flow to the heart. Choice A is incorrect because chest pain that persists at rest should be addressed immediately, not waiting for 30 minutes. Choice C is incorrect as avoiding physical activity is not a recommended approach during an angina episode. Choice D is incorrect because nitroglycerin should be used during chest pain episodes, not as a preventive measure before physical activity.

5. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
