A nurse is caring for a client 8 hr postoperative following a total knee replacement. Which of the following actions should the nurse take?

Encourage increased fluid take.

Promote bed rest for 5-7 days.

Place a pillow under the affected limb.

Apply cool compresses to the affected limb every 6 hr.

Answer and Explanation

The Correct Answer is D

A.   Encouraging adequate fluid intake is important postoperatively to maintain hydration and support normal physiological functions. However, the amount of fluid intake should be within the client's tolerance and as prescribed by the healthcare provider. It helps prevent complications such as dehydration and promotes circulation, which is beneficial for wound healing.

B.   While some rest and limited mobility are initially recommended after knee replacement surgery to allow for healing and to prevent complications, prolonged bed rest for 5-7 days is not typically necessary or recommended. Early mobilization and gradual increase in activity are encouraged to prevent complications such as deep vein thrombosis and to promote recovery.
C.   Placing a pillow directly under the knee is not recommended as it can lead to decreased range of motion and potential contractures.
D.   Cold therapy, such as applying cool compresses, is often used to reduce swelling and pain in the initial postoperative period. It can help manage pain and discomfort and promote comfort for the client.

Correct Answer is ["A","B","C","E"]

Explanation

A. Postoperative patients often experience muscle tension and discomfort due to lying in one position for an extended period. A gentle back massage can help relieve muscle stiffness, promote relaxation, and improve circulation. It is a non-invasive comfort measure that can enhance the client's overall well- being.
B. Teaching relaxation techniques such as deep breathing exercises, guided imagery, or progressive muscle relaxation can help the client manage pain, reduce anxiety, and promote faster recovery. These techniques are beneficial postoperatively as they encourage relaxation and improve overall comfort.
C. Postoperative clients are at risk of developing respiratory complications such as atelectasis (partial lung collapse) or pneumonia due to shallow breathing or inadequate lung expansion. Coughing and deep breathing exercises help to clear secretions, improve lung function, and prevent respiratory complications. It is typically recommended to perform these exercises every hour to maintain lung expansion and prevent complications.
D. Encouraging the client to turn every 2 hours (D), not every 4 hours, is essential to prevent pressure ulcers and promote circulation.
E. Postoperative pain management is essential for the client's comfort and recovery. Pain can interfere with the client's ability to cough, deep breathe, and move effectively, which may increase the risk of complications. Administering analgesics as needed helps to control pain, improve overall comfort, and promote participation in necessary activities such as coughing, deep breathing, and turning.

A. Hemoglobin B. Creatinine C. Blood urea nitrogen D. Potassium

Correct Answer is A

Explanation

A. Hemoglobin levels are important for assessing oxygen-carrying capacity of the blood. While anemia can affect tissue oxygenation and exacerbate symptoms in heart failure, it is not directly related to the risk of digoxin toxicity.
B. Creatinine levels are used to assess kidney function. Impaired kidney function can affect the clearance of digoxin from the body, potentially increasing the risk of toxicity. However, potassium levels have a more direct impact on the risk of digoxin toxicity.
C. BUN levels are also used to assess kidney function. Similar to creatinine, impaired kidney function can affect digoxin clearance, but potassium levels are more directly related to the risk of digoxin toxicity.
D. Potassium levels are critical because hypokalemia (low potassium) can predispose the client to digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in cardiac cells. When potassium levels are low, digoxin can bind more readily to these pumps, leading to increased toxicity and potentially life-threatening arrhythmias such as ventricular tachycardia or ventricular fibrillation.
