Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

2. The charge nurse of the critical care unit informed at the beginning of the shift that a less than optimal number of registered nurses would be working that shift. In planning assignments, which client should receive the most care hours by a registered nurse?

• A. A 34-year-old admitted today after an emergency appendectomy who has a peripheral intravenous catheter and a Foley catheter.
• B. A 48-year-old marathon runner with a central venous catheter experiencing nausea and vomiting due to electrolyte disturbance following a race.
• C. A 63-year-old chain smoker with chronic bronchitis receiving oxygen via nasal cannula and a saline-locked peripheral intravenous catheter.
• D. An 82-year-old client with Alzheimer's disease and a newly fractured femur with a Foley catheter and soft wrist restraints applied.

Correct answer: D

Rationale: The 82-year-old client with Alzheimer's disease and a newly fractured femur should receive the most care hours by a registered nurse because they are at the highest risk for injury and complications. The client's age, diagnosis of Alzheimer's disease, and the presence of a newly fractured femur along with the Foley catheter and wrist restraints indicate a need for close monitoring and care. Choice A is less critical as the client is stable post-appendectomy. Choice B, though experiencing symptoms, is not at the same level of risk as the client in Choice D. Choice C, while requiring oxygen support, does not have the same level of acuity and complexity as the client in Choice D.

3. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

• A. Anuria for the last 12 hours.
• B. Tachycardia and hypotension.
• C. Decreased urine output.
• D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

4. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

5. An unlicensed assistive personnel (UAP) assigned to obtain client vital signs reports to the charge nurse that a client has a weak pulse with a rate of 44 beats/minute. What action should the charge nurse implement?

• A. Instruct the UAP to count the client's apical pulse rate for sixty seconds.
• B. Determine if the UAP also measured the client's capillary refill time.
• C. Assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present.
• D. Notify the healthcare provider of the abnormal pulse rate and pulse volume.

Correct answer: C

Rationale: The correct action for the charge nurse to implement in this situation is to assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present. This helps to confirm the accuracy of the reported weak pulse. In this scenario, it is crucial to involve a licensed nurse to further assess the situation and provide a more comprehensive evaluation. Inaccurate pulse readings can lead to inappropriate interventions or unnecessary alarm. Instructing the UAP to count the apical pulse may not address the accuracy issue. Checking capillary refill time is not directly related to confirming the weak pulse rate. Notifying the healthcare provider immediately may be premature without confirming the accuracy of the pulse reading first.
