Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. A client with a history of heart failure is admitted with severe dyspnea. Which intervention should the nurse implement first?

• A. Administer oxygen at 2 liters per minute via nasal cannula.
• B. Place the client in a high Fowler's position.
• C. Obtain a 12-lead electrocardiogram (ECG).
• D. Administer intravenous furosemide (Lasix).

Correct answer: B

Rationale: The correct answer is to place the client in a high Fowler's position first. This intervention helps improve breathing and oxygenation in clients with severe dyspnea, including those with heart failure. Elevating the head of the bed reduces the work of breathing and enhances lung expansion. Administering oxygen, obtaining an ECG, and administering furosemide are important interventions in the management of heart failure, but placing the client in a high Fowler's position is the priority to address the immediate need for improved breathing and oxygenation.

3. The nurse is assessing a client with a suspected deep vein thrombosis (DVT). Which finding supports this diagnosis?

• A. Positive Homan's sign.
• B. Unilateral leg swelling.
• C. Bilateral calf pain.
• D. Redness and warmth in the affected leg.

Correct answer: D

Rationale: The correct answer is D: Redness and warmth in the affected leg. These are classic signs of deep vein thrombosis (DVT) and support the diagnosis. Choice A, Positive Homan's sign, is an outdated and unreliable test for DVT, so it is not the best choice. Choice B, Unilateral leg swelling, can be seen in DVT but is less specific compared to redness and warmth. Choice C, Bilateral calf pain, is not a typical finding in DVT, as the pain in DVT is usually unilateral.

4. A graduate nursing student requests information, including laboratory findings and chest x-ray results, about all clients with symptoms of H1N1 who have been seen during the last month in a community health clinic. Which action should the charge nurse take?

• A. Ask if permission has been obtained from the research committee.
• B. Ask the student to sign a standard waiver form.
• C. Obtain written authorization from clients to release the information.
• D. Provide the information for research purposes only.

Correct answer: C

Rationale: The correct action for the charge nurse to take is to obtain written authorization from clients to release the information. This step is crucial to ensure compliance with privacy laws and ethical standards. Asking for permission from the research committee (Choice A) may not address the individual clients' rights to privacy. Asking the student to sign a standard waiver form (Choice B) is not appropriate, as the authorization should come from the clients themselves. Providing the information for research purposes only (Choice D) without proper authorization violates client confidentiality and privacy.

5. The healthcare provider provides teaching to a group of evacuees in a mass casualty center after a natural flooding disaster. Which information should the healthcare provider include in the teaching plan? (select one that does not apply.)

• A. wash all fruits and vegetables thoroughly in running tap water
• B. identify all sexual contacts since the evacuation process
• C. take all doses of prophylactic prescriptions for diarrhea
• D. clean hands using soap, clean water, or waterless antibacterial solutions

Correct answer: B

Rationale: In the aftermath of a flooding disaster, educating evacuees on proper hygiene practices like washing fruits and vegetables, taking prophylactic prescriptions, and practicing hand hygiene is crucial to prevent the spread of diseases. Option B, identifying sexual contacts, is not relevant to preventing post-disaster health risks and should not be included in the teaching plan.
