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.
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 C
Explanation
A. A hematocrit of 40% is within the normal range for females, which is typically around 37-47%. This result is not concerning and does not typically require immediate notification to the surgeon.
B. A creatinine level of 0.9 mg/dL is within the normal range for adults (normal range varies slightly among laboratories but is generally around 0.5-1.1 mg/dL). This result indicates normal kidney function and does not require immediate notification.
C. A white blood cell (WBC) count of 20,000/mm3 is elevated above the normal range, which is typically between 4,500-11,000/mm3. An elevated WBC count could indicate infection or inflammation. Given the client is preoperative, an elevated WBC count may suggest an underlying infection that needs to be addressed before proceeding with surgery. The nurse should notify the surgeon promptly so appropriate evaluation and management can be initiated.
D. A potassium level of 3.8 mEq/L is within the normal range (normal range is generally 3.5-5.0 mEq/L). This result is not concerning and does not require immediate notification to the surgeon.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"E"}
Explanation
Correct choices are; Metabolic acidosis:
This can occur due to the client's diarrhea, leading to loss of bicarbonate (HCO3-) through the gastrointestinal tract. The ABG results show a pH slightly below normal (7.33) and a decreased bicarbonate level (19 mEq/L), indicative of metabolic acidosis.
Hypernatremia:
The client's sodium level is elevated at 149 mEq/L (normal range is 136-145 mEq/L). This indicates hypernatremia, which could be due to dehydration from diarrhea and possibly inadequate fluid intake.
