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 B
Explanation
A. Deferasirox is a medication used to treat chronic iron overload due to blood transfusions. It is not used as an antidote for heparin.
B. Protamine sulfate is the antidote for heparin. It works by binding to heparin, neutralizing its anticoagulant effects. Protamine sulfate is typically used in cases of heparin overdose or when rapid reversal of heparin's effects is necessary, such as during surgery or if there is active bleeding.
C. Acetylcysteine is used as an antidote for acetaminophen (paracetamol) overdose due to its ability to replenish glutathione stores in the liver and protect against liver damage. It has no role in reversing heparin's effects.
D. Vitamin K is the antidote for warfarin, not heparin. It promotes the synthesis of clotting factors in the liver that are inhibited by warfarin, thus reversing its anticoagulant effects.
Correct Answer is D
Explanation
A. Metabolic alkalosis is characterized by an increase in bicarbonate (HCO3-) levels in the blood, resulting in an elevated pH (>7.45). Shallow respirations are less likely to cause metabolic alkalosis directly.
B. This is not likely the initial risk. Respiratory alkalosis occurs due to hyperventilation, leading to excessive elimination of CO2 (carbon dioxide), which raises the blood pH (>7.45). Shallow respirations typically result in retention of CO2, leading to respiratory acidosis rather than alkalosis.
C. Metabolic acidosis occurs when there is an increase in acid (decreased pH <7.35) or a decrease in bicarbonate levels in the blood. Shallow respirations can lead to hypoventilation and retention of CO2, resulting in respiratory acidosis initially.
D. Shallow respirations at a rate of 9 breaths per minute reduce the elimination of CO2, leading to its accumulation in the blood. This accumulation lowers the blood pH (<7.35), causing respiratory acidosis. Therefore, the client is initially at risk for developing respiratory acidosis due to ineffective ventilation.
