1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Serum glucose level
- C. White blood cell count
- D. Prothrombin time (PT)
Correct answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.
2. The nurse needs to add a medication to a liter of 5% Dextrose in Water (D5W) that is already infusing into a client. At what location should the nurse inject the medication?
- A. Medication port
- B. IV drip chamber
- C. Y-site connector
- D. At the hub of the IV catheter
Correct answer: A
Rationale: The correct answer is the medication port. When adding medication to an already infusing IV solution, it should be done through the medication port to ensure direct delivery into the bloodstream without interrupting the primary IV line. Injecting the medication into the IV drip chamber, Y-site connector, or at the hub of the IV catheter can lead to dilution, inaccurate dosing, or potential blockages in the IV line, which can compromise the effectiveness of the medication and patient safety.
3. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. Which action should the nurse take?
- A. Encourage the UAP to remain in the client's room until the procedure is completed.
- B. Explain that the hand rub can be completed in less than 2 minutes.
- C. Inform the UAP that handwashing helps to promote better asepsis.
- D. Determine why the UAP was not wearing gloves in the client's room.
Correct answer: B
Rationale: The correct answer is B. Explaining that hand rubs can be effective with less time allows the UAP to perform the procedure more efficiently while maintaining asepsis. Choice A is incorrect because the UAP does not need to remain in the client's room until the procedure is completed. Choice C is incorrect as the UAP was using an alcohol-based gel hand cleaner, not handwashing. Choice D is incorrect as the scenario does not mention any issue with glove usage, so it is not relevant to the situation at hand.
4. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Hemoglobin level
- C. White blood cell count
- D. Serum sodium level of 135 mEq/L
Correct answer: A
Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.
5. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Muscle weakness
- D. Decreased deep tendon reflexes
Correct answer: A
Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.
