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 D
Explanation
A. PaCO2 (partial pressure of carbon dioxide) reflects the respiratory component of acid-base balance. In metabolic acidosis, the respiratory system compensates by increasing ventilation to decrease PaCO2 (hyperventilation). Therefore, PaCO2 is typically below normal (less than 35-45 mm Hg) in metabolic acidosis, not above 45 mm Hg.
B. HCO3 (bicarbonate) is a buffer that helps regulate pH in the body. In metabolic acidosis, there is a primary decrease in HCO3 due to either increased acid production (e.g., lactic acidosis, ketoacidosis) or decreased acid elimination (e.g., renal failure). Therefore, HCO3 is typically below normal (< 22-26 mEq/L) in metabolic acidosis, not above 26 mEq/L.
C. PaO2 (partial pressure of oxygen) measures the oxygen level in the blood. It is not directly related to the diagnosis of metabolic acidosis. Low PaO2 levels may indicate respiratory dysfunction or impaired gas exchange but are not specific to metabolic acidosis.
D. pH below 7.35 indicates acidosis. In metabolic acidosis, the primary defect is a decrease in blood pH due to an excess of acids or a loss of bases. The pH typically decreases below the normal range of 7.35-7.45 in metabolic acidosis.
Correct Answer is D
Explanation
A. Applying a warm compress can help dilate the blood vessels, potentially improving circulation around the IV site. This can sometimes alleviate discomfort caused by irritation or infiltration. However, if there is significant pain or swelling, warm compresses may not be sufficient.
B. Applying firm pressure on the syringe plunger during the flush is not recommended. Excessive force could potentially cause damage to the vein or exacerbate pain and discomfort. It's important to flush gently to maintain patency and avoid causing further irritation or complications.
C. If the client reports pain above the IV saline lock and there are signs of infiltration (such as swelling, coolness, or blanching of the skin around the site), removing the IV saline lock may be necessary. Infiltration occurs when IV fluid leaks into the surrounding tissue instead of flowing into the vein, which can lead to discomfort and complications.
D. Injecting the solution more slowly during the flush can help minimize discomfort and reduce the risk of causing further damage. Slower infusion allows for better tolerance by the vein and surrounding tissues, decreasing the likelihood of pain or infiltration.
