Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

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

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.

2. The nurse is caring for a client with a history of congestive heart failure (CHF) who is receiving digoxin therapy. The client reports seeing halos around lights. Which action should the nurse take?

• A. Assess the client's digoxin level
• B. Increase the client's fluid intake
• C. Check the client's blood pressure
• D. Administer a dose of potassium

Correct answer: A

Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity. The nurse should assess the client's digoxin level to determine if the dose needs to be adjusted or if the medication should be held. Increasing fluid intake or checking blood pressure would not directly address the symptom of halos around lights. Administering a dose of potassium is not indicated without knowing the digoxin level and could potentially worsen the toxicity.

3. 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.

4. A client with rheumatoid arthritis is prescribed methotrexate. What is the most important teaching point for the nurse to provide?

• A. Take the medication with food to avoid gastrointestinal upset.
• B. Monitor for signs of infection, such as a sore throat.
• C. Increase fluid intake to prevent dehydration.
• D. Avoid direct sunlight to prevent photosensitivity.

Correct answer: D

Rationale: The most important teaching point for a client prescribed methotrexate is to avoid direct sunlight to prevent photosensitivity. Methotrexate can make the skin more sensitive to sunlight, increasing the risk of sunburn and skin damage. Choices A, B, and C are important aspects of client care but are not specifically related to the side effect of photosensitivity caused by methotrexate.

5. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has been experiencing increasing shortness of breath. Which finding requires immediate intervention?

• A. A respiratory rate of 26 breaths per minute
• B. Use of accessory muscles for breathing
• C. Barrel chest appearance
• D. A pulse oximetry reading of 88%

Correct answer: D

Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to improve oxygenation. Hypoxemia can lead to serious complications if not addressed promptly. While a respiratory rate of 26 breaths per minute and the use of accessory muscles for breathing are concerning in COPD, they do not indicate an immediate life-threatening situation. Similarly, a barrel chest appearance is a common finding in COPD and does not require urgent intervention compared to the critical need to address hypoxemia.
