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. A client has a prescription for digoxin. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid taking antacids at the same time as this medication.
• C. Take this medication if your heart rate is above 100/min.
• D. Notify your provider if you experience nausea or visual changes.

Correct answer: D

Rationale: The correct instruction the nurse should include for a client prescribed digoxin is to notify the provider if they experience nausea or visual changes, as these symptoms can indicate digoxin toxicity. Option A is incorrect because digoxin should be taken on an empty stomach for better absorption. Option B is incorrect as antacids can interfere with the absorption of digoxin. Option C is incorrect as taking digoxin based on heart rate alone is not appropriate.

3. A nurse is caring for a client who has pneumonia and is receiving oxygen therapy. Which of the following findings indicates the need for suctioning?

• A. Increased respiratory rate.
• B. Oxygen saturation 96%.
• C. Clear lung sounds.
• D. Productive cough.

Correct answer: A

Rationale: The correct answer is A: Increased respiratory rate. An increased respiratory rate suggests the client is having difficulty clearing secretions and may require suctioning. Oxygen saturation of 96% is within the normal range and indicates adequate oxygenation. Clear lung sounds suggest good air entry without the need for suctioning. A productive cough, although a symptom of pneumonia, does not directly indicate the need for suctioning.

4. A healthcare provider is teaching a client who has a new prescription for levothyroxine. Which of the following instructions should the healthcare provider include?

• A. Take this medication with meals.
• B. Take this medication at the same time every day.
• C. Report any chest pain to your healthcare provider immediately.
• D. Take an antacid if indigestion occurs.

Correct answer: B

Rationale: The correct instruction for a client prescribed levothyroxine is to take the medication at the same time every day. This consistency is important for maintaining stable thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach to ensure proper absorption. Choice C is important but not directly related to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

5. A client is receiving discharge teaching for a new prescription of warfarin. Which statement by the client indicates an understanding of the teaching?

• A. I will need to increase my intake of leafy green vegetables.
• B. I will avoid drinking grapefruit juice while taking warfarin.
• C. I will have my INR checked regularly.
• D. I will take my medication at the same time each day.

Correct answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.
