Nursing Elites

1. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

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

Correct answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

2. What is the most important assessment for a patient with suspected pneumonia?

• A. Monitor lung sounds
• B. Check oxygen saturation
• C. Assess for cough
• D. Assess for fever

Correct answer: A

Rationale: The most important assessment for a patient with suspected pneumonia is to monitor lung sounds. Lung sounds provide crucial information about the severity of pneumonia, such as crackles or decreased air entry. This assessment helps in evaluating the effectiveness of ventilation and oxygenation. While checking oxygen saturation is important, monitoring lung sounds gives more direct information about the lung involvement in pneumonia. Assessing for cough and fever are also relevant but do not provide as direct and critical information as monitoring lung sounds in the context of suspected pneumonia.

3. A nurse is preparing to administer vancomycin IV to a client who has methicillin-resistant Staphylococcus aureus (MRSA). Which of the following actions should the nurse take?

• A. Administer the medication over 60 minutes
• B. Monitor the client's blood glucose level during administration
• C. Infuse the medication rapidly to reduce the risk of infection
• D. Administer the medication using a filter needle

Correct answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

4. A nurse is teaching a prenatal class about infection prevention. Which of the following statements indicates an understanding of the teaching?

• A. I can visit someone with chickenpox 5 days after the sores crust.
• B. I should avoid cleaning my cat's litter box during pregnancy.
• C. I should wash my hands with hot water for 10 seconds after gardening.
• D. I can take antibiotics for viral infections.

Correct answer: B

Rationale: The correct answer is B because avoiding cleaning the cat's litter box during pregnancy reduces the risk of toxoplasmosis, which can be harmful to the developing fetus. Choice A is incorrect because visiting someone with chickenpox should be avoided as it is highly contagious. Choice C is incorrect as handwashing after gardening should involve soap and water, not just hot water, for effective infection prevention. Choice D is incorrect because antibiotics are ineffective against viral infections.

5. A charge nurse is teaching a newly licensed nurse about clients designating a health care proxy. Which of the following information should the charge nurse include?

• A. The proxy should make health care decisions for the client regardless of the client's ability to do so
• B. The proxy can make financial decisions if the need arises
• C. The proxy can make treatment decisions if the client is under anesthesia
• D. The proxy should manage legal issues for the client

Correct answer: C

Rationale: The correct answer is C because the health care proxy can make treatment decisions for the client if the client is under anesthesia. This aligns with the concept of durable power of attorney for health care, where the proxy is authorized to make health care decisions when the client is unable to do so. Choices A, B, and D are incorrect. Choice A is incorrect because the proxy should make health care decisions only when the client is unable to do so. Choice B is incorrect as financial decisions are not typically within the scope of a health care proxy. Choice D is incorrect as managing legal issues is not the primary role of a health care proxy.
