A nurse is reviewing the medication list for a client who has a new prescription for warfarin. The nurse should recognize which is incompatible with warfarin?
Vitamin A
Alprazolam
Vitamin K
Furosemide
The Correct Answer is C
A) Vitamin A: While vitamin A can affect various bodily functions, it is not known to have a direct interaction with warfarin. Therefore, it is not considered incompatible with warfarin therapy.
B) Alprazolam: This medication, a benzodiazepine, is primarily used to treat anxiety and does not have a significant interaction with warfarin. Thus, it is not incompatible with warfarin therapy.
C) Vitamin K: This vitamin is a critical consideration when a client is on warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, so an increased intake of vitamin K can counteract the effects of warfarin, making this the correct answer. Clients on warfarin should maintain a consistent intake of vitamin K to prevent fluctuations in their INR levels.
D) Furosemide: This loop diuretic is used to manage conditions such as heart failure and edema. While it may affect electrolyte levels, it does not have a direct interaction that would render it incompatible with warfarin. It can be safely used alongside warfarin with appropriate monitoring.

Correct Answer is ["A","B","C","D"]
Explanation
A) "I will apply my compression stockings." Compression stockings are a standard recommendation for clients with peripheral venous disease (PVD). They help improve venous return and reduce symptoms like swelling and discomfort, indicating that the client understands the importance of managing their condition.
B) "I will limit long periods of standing." This statement reflects an understanding of the need to avoid activities that can exacerbate venous stasis and contribute to worsening symptoms in PVD. Limiting long periods of standing helps promote better blood flow and reduces the risk of complications.
C) "I may develop a brownish discoloration to my lower extremities." This statement indicates an awareness of a potential complication of PVD, often caused by venous stasis and pooling of blood. Brownish discoloration, or stasis dermatitis, can occur in the lower extremities, showing the client’s understanding of the condition.
D) "With this problem, I may have lower extremity hair loss." This statement is accurate as well; hair loss on the lower extremities can occur with PVD due to reduced blood flow and oxygen supply to the tissues. This recognition indicates that the client understands the potential effects of their diagnosis.
E) "I will only take my cholesterol lowering medication every other day in the afternoon." This statement reflects a misunderstanding of medication management. Clients with PVD should take prescribed medications as directed to manage their condition effectively, and altering the dosing schedule without consulting a healthcare provider can lead to adverse outcomes.
Correct Answer is C
Explanation
A) Apply cold therapy to the affected leg: Cold therapy may be used for certain conditions to reduce swelling and pain, but in the case of suspected deep vein thrombosis (DVT) indicated by redness, warmth, tenderness, and pain in the calf, cold therapy is not appropriate. Instead, the focus should be on confirming the diagnosis before applying any treatment.
B) Monitor Homan's sign: Homan's sign involves dorsiflexion of the foot to assess for pain in the calf, which can suggest DVT. However, it is no longer considered a reliable diagnostic tool. Instead, confirmation through imaging or other diagnostic measures is preferred, so simply monitoring this sign would not be sufficient in this situation.
C) Obtain a venous duplex ultrasound: A venous duplex ultrasound is the gold standard for
diagnosing DVT. Given the client’s symptoms—redness, warmth, tenderness, and pain in the calf—the appropriate order is to obtain this ultrasound to confirm the presence of a thrombus. This imaging study provides critical information for diagnosis and subsequent management.
D) Obtain impedance plethysmography: While impedance plethysmography can assess venous flow and help diagnose DVT, it is less commonly used than venous duplex ultrasound. The more direct and widely accepted method for diagnosing DVT in this scenario is the ultrasound, making this option less suitable as the initial order.
