Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A client is hospitalized 3 days prior to a total hip arthroplasty and reports a high level of pain with ambulation. The client has been taking warfarin at home, which is now discontinued. To prevent the formation of blood clots, which action should the nurse take?
A
Have the client limit physical activity.
B
Monitor partial thromboplastin (PTT) time.
C
Administer the prescribed enoxaparin (Lovenox).
D
Encourage a diet high in vitamin K.
Explanation: 

Detailed explanation-1: -International normalized ratio (INR) Rationale: The INR is used to monitor clients who are taking warfarin.

Detailed explanation-2: -Anticoagulants are the medications most commonly used to treat DVT or PE. Bleeding can be a complication of anticoagulant therapy. The most frequently used injectable anticoagulants are unfractionated heparin, low molecular weight heparin (LMWH), and fondaparinux.

Detailed explanation-3: -What are the complications of a DVT? The biggest problem we worry about with a DVT is that the clot will dislodge (go from being a thrombus to being an embolus) and block vessels in the lung, becoming a pulmonary embolism (also called a PE).

Detailed explanation-4: -Walking and exercises that increase blood circulation are effective measures to keep the blood flow steady. Wearing compress stockings are often used as a prevention method for patients who are at a higher risk of developing thrombosis.
