A nurse is caring for a client who had IV fluids initiated at 0330. The IV fluids are infusing at 120 mL/hr. The nurse should record how many mL of IV fluids on the intake record at 0600?

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.

A. Metabolic acidosis is characterized by a decrease in bicarbonate or an increase in acids, which can be caused by conditions like kidney failure or diabetic ketoacidosis, but it is not typically associated with numbness and tingling.
B. Respiratory alkalosis is characterized by a high pH (>7.45) and a decreased PaCO2 (<35 mm Hg). It typically results from hyperventilation, which leads to excessive elimination of CO2 and subsequent alkalosis. This condition is less likely to occur in gastroenteritis unless there are other complicating factors such as anxiety or pain causing increased respiratory rate.
C. In the context of gastroenteritis, where there may be a loss of stomach acids through vomiting or diarrhea, the most likely acid-base imbalance would be metabolic alkalosis.
D. Respiratory acidosis is characterized by a low pH and an elevated PaCO2 (>45 mm Hg). It results from hypoventilation, leading to retention of CO2 and subsequent acidosis. Respiratory acidosis would not typically present with numbness and tingling in the extremities in the context of gastroenteritis.
