Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. What is the initial action a healthcare provider should take when a patient presents with chest pain?

• A. Administer aspirin
• B. Give oxygen therapy
• C. Obtain ECG
• D. Prepare for surgery

Correct answer: C

Rationale: The correct initial action when a patient presents with chest pain is to obtain an ECG. This helps assess the heart's electrical activity and determine the cause of chest pain. Administering aspirin or oxygen therapy may be necessary later based on the ECG findings, but obtaining an ECG is the priority to evaluate the cardiac status. Surgery preparation is not the initial action for chest pain and should only be considered after a thorough assessment.

3. Which lab value should be monitored for a patient on warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.

4. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

5. A nurse is preparing to administer packed RBCs to a client. Which of the following actions should the nurse take first?

• A. Prime the IV tubing with dextrose 5% in water
• B. Ensure the client's consent is on file
• C. Check the client's identification using two identifiers
• D. Administer the blood through a 22-gauge catheter

Correct answer: C

Rationale: The correct first action for the nurse to take when preparing to administer packed RBCs is to check the client's identification using two identifiers. This step is crucial to ensure that the right blood is given to the right client, preventing any transfusion errors. Priming the IV tubing with dextrose 5% in water and administering the blood through a 22-gauge catheter are important steps but should come after confirming the client's identity. Ensuring the client's consent is on file is also important but is not the immediate priority when preparing to administer packed RBCs.
