A nurse is caring for 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)?
Enoxaparin
Alteplase (tPA)
Warfarin
Clopidogrel
The Correct Answer is A
A. Enoxaparin. Enoxaparin is a low molecular weight heparin used for prophylaxis against DVT. It works by inhibiting clotting factors and is commonly used postoperatively to prevent DVT formation.
B. Alteplase (tPA): Alteplase is a thrombolytic agent used to dissolve clots and is not used for DVT prophylaxis.
C. Warfarin: Warfarin requires monitoring and has a delayed onset, making it less suitable for immediate postoperative DVT prophylaxis.
D. Clopidogrel: Clopidogrel is an antiplatelet agent and is not typically used for DVT prophylaxis postoperatively.

Correct Answer is B
Explanation
A. Tell the client that being in foster care can help with coping: Minimizes the client's emotional needs and may not address the grief adequately.
B. Explain how grief support groups could increase coping and social support. Grief support groups offer peer support and validation, which can be crucial for coping with loss and loneliness. Encouraging participation in support groups helps the client connect with others who have experienced similar losses and facilitates coping.
C. Encourage the client to ask the provider for medication: Not typically the first approach for addressing social support issues.
D. Suggest using the internet as a source for finding supportive friends: Safety and reliability of online friendships can vary, and in-person support is often more beneficial.
Correct Answer is C
Explanation
A. Systemic lupus erythematosus (SLE): SLE is an autoimmune disease but is not directly linked to the pathophysiology of HIT.
B. Placental abruption: Placental abruption is a complication of pregnancy and is not a risk factor for HIT.
C. Heparin therapy for deep-vein thrombosis (DVT): Correct Answer. Heparin therapy itself, especially in the treatment of deep-vein thrombosis, is a significant risk factor for developing HIT due to the exposure to heparin.
D. Warfarin therapy for atrial fibrillation: Warfarin is not associated with the development of HIT.
