Nursing Elites

1. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.

2. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

3. A nurse is assessing a client who is receiving a blood transfusion. Which of the following findings should the nurse identify as an indication of a hemolytic transfusion reaction?

• A. Low back pain.
• B. Bradycardia.
• C. Chills.
• D. Distended neck veins.

Correct answer: A

Rationale: The correct answer is A: Low back pain. Low back pain is a common sign of a hemolytic transfusion reaction, indicating the destruction of red blood cells. This finding requires immediate intervention as it can lead to serious complications such as renal failure. Bradycardia (choice B) is not typically associated with a hemolytic transfusion reaction. Chills (choice C) can be seen in febrile non-hemolytic transfusion reactions. Distended neck veins (choice D) are more indicative of fluid overload rather than a hemolytic reaction.

4. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be decreased?

• A. Bilirubin.
• B. Albumin.
• C. Ammonia.
• D. Prothrombin time.

Correct answer: B

Rationale: In clients with cirrhosis, albumin levels are typically decreased due to impaired liver function. Bilirubin levels are often increased in cirrhosis due to the liver's inability to process bilirubin efficiently. Ammonia levels may be elevated in cirrhosis due to impaired ammonia metabolism by the liver. Prothrombin time is usually prolonged in cirrhosis because the liver's ability to synthesize clotting factors is impaired.

5. A nurse is caring for a client who has a chest tube following thoracic surgery. Which of the following actions should the nurse take?

• A. Clamp the chest tube when assisting the client out of bed.
• B. Empty the drainage system every 8 hours.
• C. Keep the collection device below the client's chest.
• D. Strip the chest tube every 4 hours.

Correct answer: C

Rationale: The correct action for the nurse to take is to keep the collection device below the client's chest. This positioning ensures proper drainage of fluid from the chest, preventing backflow of fluids. Clamping the chest tube when assisting the client out of bed is incorrect as it can lead to fluid accumulation and potential complications. Emptying the drainage system every 8 hours is necessary but not the priority over maintaining proper positioning. Stripping the chest tube every 4 hours is an outdated practice and can cause damage to the tissue and should be avoided.
