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. Which lab value is critical for patients on warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor sodium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

3. When should healthcare professionals perform hand hygiene?

• A. Before and after patient contact
• B. Before and after performing procedures
• C. After using the restroom
• D. After touching contaminated surfaces

Correct answer: A

Rationale: Healthcare professionals should perform hand hygiene before and after patient contact to prevent the spread of infections. While choices B, C, and D are also important times to practice hand hygiene, they are not as crucial as before and after patient contact because patient contact poses a higher risk of transmitting infections.

4. A client is receiving discharge instructions following a stroke. Which of the following client statements indicates an understanding of the teaching?

• A. I will avoid using aspirin for pain.
• B. I will consume dairy products to increase my calcium intake.
• C. I will drink 1.5 to 2 liters of fluid each day.
• D. I will need to limit my intake of fiber.

Correct answer: A

Rationale: The correct answer is A. Avoiding aspirin is crucial for this client as it can increase the risk of bleeding after a stroke. Choice B about consuming dairy products for calcium intake is not directly related to stroke management. Choice C regarding fluid intake is a good practice for overall health but not specifically related to stroke care. Choice D about limiting fiber intake is not typically a concern after a stroke unless there are specific complications that warrant it.

5. Which medication is used to reverse the effects of opioid overdose?

• A. Naloxone
• B. Epinephrine
• C. Atropine
• D. Lidocaine

Correct answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.
