Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?

• A. Hemoglobin
• B. White blood cell count
• C. Platelet count
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.

2. The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?

• A. Irrigate the catheter daily
• B. Ensure the catheter bag is always below bladder level
• C. Change the catheter every 48 hours
• D. Administer prophylactic antibiotics

Correct answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.

3. The nurse assigns an unlicensed assistive personnel (UAP) to feed a client who is at risk for aspiration. What action should the nurse take to ensure safety?

• A. Inform the UAP that suction is available at the bedside.
• B. Instruct the UAP to notify the nurse if the client chokes.
• C. Observe the UAP's ability to implement precautions during feeding.
• D. Ask the UAP about previous experience in performing this skill.

Correct answer: C

Rationale: Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.

4. When preparing to administer blood to a client, what is the most important action to ensure client safety during this procedure?

• A. Check the client’s blood type compatibility
• B. Monitor the client for signs of transfusion reaction
• C. Verify the correct client and blood product with another healthcare professional
• D. All of the above

Correct answer: D

Rationale: The most important action to ensure client safety during a blood transfusion is to implement multiple safety checks. Checking the client’s blood type compatibility is crucial as it helps prevent major transfusion reactions. Monitoring the client for signs of transfusion reaction is essential to detect any adverse reactions early. Verifying the correct client and blood product with another healthcare professional adds an extra layer of safety by ensuring the right blood is administered to the right patient. Choosing 'All of the above' (Option D) is the correct answer because each action plays a vital role in ensuring the safety and well-being of the client during a blood transfusion. Options A, B, and C are not exclusive; they complement each other to provide comprehensive safety measures.

5. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
