Correct Answer is D

Explanation

A. Increasing dietary intake of vitamin K would decrease the effectiveness of warfarin, as vitamin K is involved in clotting factor synthesis.

B. St. John's wort decreases the effects of warfarin, so it should be avoided.

C. Protamine sulfate is the antidote for heparin, not warfarin. The antidote for warfarin overdose is vitamin K.

D. Monitoring prothrombin time (PT) and INR is essential to assess the effectiveness and safety of warfarin therapy.

A. A vein in the client's dominant arm B. A vein proximal to the previous site C. A vein that feels hard to the touch D. A vein on the client's wrist

Correct Answer is B

Explanation

A. A vein in the dominant arm can be used, but it is not necessarily the best choice for a re-insertion.

B. A vein proximal to the previous site is the best option to avoid using the same vein where complications (e.g., infiltration, thrombosis) have occurred.

C. A vein that feels hard to the touch may indicate previous injury or sclerosis, making it unsuitable for insertion.

D. The wrist vein is less ideal because it is smaller and more difficult to access compared to veins in the forearm.
