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 with a pulmonary embolism is being cared for by a nurse. Which of the following interventions should the nurse include in the plan of care?

• A. Encourage the client to ambulate frequently.
• B. Place the client in a prone position.
• C. Administer anticoagulants as prescribed.
• D. Initiate seizure precautions.

Correct answer: C

Rationale: Administering anticoagulants as prescribed is a crucial intervention for clients with pulmonary embolism to prevent further clot formation. Encouraging the client to ambulate frequently may dislodge the clot and lead to worsening symptoms. Placing the client in a prone position can compromise respiratory function. Initiating seizure precautions is not directly related to the management of pulmonary embolism.

3. A nurse is planning care 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 therapy?

• A. Serum calcium level
• B. Platelet count
• C. INR
• D. WBC count

Correct answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

4. A client is being discharged with a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication with meals to avoid stomach upset.
• B. Take this medication at the same time every day.
• C. Notify your provider if you experience chest pain or palpitations.
• D. Take this medication with antacids to reduce indigestion.

Correct answer: B

Rationale: The correct answer is B: 'Take this medication at the same time every day.' It is crucial to take levothyroxine at the same time each day to maintain consistent thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach, usually in the morning. Choice C is important but not specific to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

5. When providing teaching for a child prescribed ferrous sulfate, which of the following instructions should the nurse include?

• A. Take with meals
• B. Take at bedtime
• C. Take with a glass of milk
• D. Take with a glass of orange juice

Correct answer: D

Rationale: The correct answer is D, 'Take with a glass of orange juice.' Ferrous sulfate is best absorbed with vitamin C, making orange juice the preferred choice. Choices A, B, and C are incorrect because taking ferrous sulfate with meals, at bedtime, or with milk can reduce its absorption due to interactions with food components like calcium, inhibiting the iron absorption process.
