Eight hours postoperative following a total knee replacement, which intervention should the nurse implement for the client?

Apply cool compresses to the affected limb every six hours.

Place a soft pillow under the affected knee.

Promote bedrest for 24 hours.

Encourage increased fluid intake.

Answer and Explanation

The Correct Answer is D

Choice A Reason
Applying cool compresses to the affected limb can help reduce swelling and provide pain relief. However, it's important to follow the surgeon's specific postoperative orders, as the application of cold can vary depending on the surgical technique and patient's condition.

Choice B Reason
Placing a soft pillow under the knee is not recommended after total knee replacement surgery. This position can lead to decreased range of motion and contractures. The knee should be kept in a more extended position to promote healing and mobility.

Choice C Reason
Promoting bedrest for an extended period is not typically advised following knee replacement surgery. Early mobilization is important to prevent complications such as deep vein thrombosis and to encourage circulation and healing. The duration of bedrest should be as per the surgeon's protocol.

Choice D Reason
Encouraging increased fluid intake is important after surgery to prevent dehydration, promote kidney function, and ensure adequate blood volume and circulation. Proper hydration is essential for healing and can help with the metabolism of medications used during and after surgery.

Correct Answer is C

Explanation

Choice A Reason:
A side-lying position with the head elevated may provide some comfort but is not the most effective position for reducing the work of breathing in emphysema patients. This position does not maximize lung expansion or aid in the optimal use of respiratory muscles.

Choice B Reason:
The Trendelenburg position, where the body is laid flat on the back with the feet higher than the head, is not recommended for emphysema patients as it can increase the pressure on the diaphragm, making breathing more difficult.

Choice C Reason:
Leaning over the bedside table, often referred to as the tripod position, is beneficial for emphysema patients. This position allows for the optimal use of respiratory muscles and helps to reduce the work of breathing by supporting the arms and allowing the shoulder girdle muscles to assist in the breathing process.

Choice D Reason:
Fowler's position, where the patient is seated with the legs either bent or straight out in front, may not be as effective as the tripod position for emphysema patients. While it does allow for better lung expansion than lying flat, it does not provide the same level of support for the respiratory muscles as leaning forward does.

A. Creatinine level is 0.8 mg/dL. B. Potassium level is 4.2 mEq/L. C. White blood cell count is 9,000 mm³. D. Hemoglobin is 7.1 g/dL.

Correct Answer is D

Explanation

Choice A Reason
A creatinine level of 0.8 mg/dL falls within the normal range for adults, which is typically 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females. This indicates normal kidney function and is not a cause for immediate intervention post-operatively.

Choice B Reason
A potassium level of 4.2 mEq/L is within the normal range, which is generally between 3.6 and 5.2 mEq/L. This level indicates a stable electrolyte balance and is not a cause for immediate concern following shoulder replacement surgery.

Choice C Reason
A white blood cell (WBC) count of 9,000 mm³ is within the normal range, which typically spans from 4,500 to 11,000 WBCs per mm³. This suggests there is no active infection or inflammation that requires immediate intervention.

Choice D Reason
A hemoglobin level of 7.1 g/dL is considered low, as the normal range for adult males is generally 13.8 to 17.2 g/dL and for adult females is 12.1 to 15.1 g/dL. Low hemoglobin can indicate anemia, which may be due to blood loss during surgery or other underlying conditions. This requires immediate intervention to address potential oxygenation issues and determine the cause of the anemia.
