A nurse is assisting with the care of a postoperative client following a total knee replacement. Which of the following medications should the nurse anticipate the provider to prescribe to prevent the formulation of a deep vein thrombosis (DVT)?
Warfarin
Alteplase (PA)
Clopidogrel
Enoxaparin
The Correct Answer is D
A. Warfarin. Warfarin (Coumadin) is an anticoagulant used to prevent blood clots, but it typically requires several days to achieve a therapeutic effect and needs close monitoring of INR (International Normalized Ratio) levels. While it can be used for long-term prevention of DVT, it's not the immediate choice for post-operative prophylaxis.
B. Alteplase (tPA). Alteplase is a thrombolytic agent, used to break down existing clots, not prevent their formation. It is typically used in emergency situations, such as for treating ischemic stroke.
C. Clopidogrel. Clopidogrel is an antiplatelet agent, often used to prevent arterial clots, not DVTs. It is more commonly used in conditions like stroke and heart disease.
D. Enoxaparin. Enoxaparin, a low molecular weight heparin, is commonly used to prevent DVT after surgery by inhibiting specific clotting factors. It’s frequently prescribed for DVT prevention in orthopedic surgery patients.

Correct Answer is A
Explanation
A. Reposition the client at least every two hours. Regular repositioning reduces prolonged pressure on specific areas of the body, which helps prevent the formation of pressure injuries.
B. Encourage the client to limit fluid intake. Adequate hydration is important for skin integrity. Limiting fluid intake could lead to dehydration, increasing the risk for skin breakdown.
C. Use a donut-shaped cushion under the client's hips. Donut-shaped cushions can actually increase pressure around the edges of the cushion and restrict blood flow, which could worsen pressure injury risk.
D. Apply a heating pad to the client's back every four hours. Heat can cause skin damage and may increase the risk of burns. Temperature regulation is important, but heating pads are not recommended for pressure injury prevention.
Correct Answer is C
Explanation
A. Frequent urination: Frequent urination is not associated with osteomyelitis, a bone infection.
B. Increased range of motion: Osteomyelitis typically causes pain and restricted movement, not increased range of motion.
C. Localized bone pain and tenderness: Osteomyelitis commonly presents with localized bone pain, tenderness, and possibly swelling due to infection.
D. Hyperpigmentation of the skin: Hyperpigmentation is not a typical sign of osteomyelitis.
