If a patient has edema in her right arm, which location is the best choice for venipuncture?

When a patient exhibits edema in one arm, it is always prudent to avoid that affected area for venipuncture. Edema can create complications, such as difficulty in locating veins and increased risk of hematoma or further swelling due to the trauma of the needle insertion. Therefore, opting for a site in the opposite arm is highly recommended.

In this scenario, choosing the left side dorsal hand represents the most suitable option because it is away from the swollen area. This location generally has accessible superficial veins, making it easier to perform a venipuncture safely and effectively. Moreover, using the left side helps in minimizing any potential discomfort or complications associated with puncturing an edematous area, ensuring better patient outcomes and experiences during the procedure.
