Question 73

Dorsal hand veins are the best choice for venipuncture in patients with scarring on forearms.

In cases where forearm veins are compromised due to scarring or injury, the dorsal hand veins provide an accessible alternative for venipuncture procedures.

A) Axillary

The axillary vein is located in the upper arm and is not typically used for venipuncture due to its deep position and the proximity to major nerves and arteries. Additionally, the risk of complications is higher when accessing this vein, making it an unsuitable choice for routine blood draws.

B) Median cubital

The median cubital vein is often the preferred vein for venipuncture; however, it is likely to be affected by the bilateral scarring on the forearms in this patient. Using this vein could lead to complications or failure to obtain a sample, and therefore, it is not the best option in this scenario.

C) Basilic

While the basilic vein can be used for venipuncture, it is located near major nerves and arteries, which increases the risk of injury during the procedure. Furthermore, the scarring on the forearms may also impact access to this vein, making it a less favorable choice compared to the dorsal hand.

D) Dorsal hand

The dorsal hand veins are generally more visible and accessible for venipuncture, especially in patients with compromised forearm veins. Since the forearms are scarred, opting for the veins in the dorsal hand minimizes complications and enhances the likelihood of a successful blood draw.

Conclusion

Dorsal hand veins are the most appropriate choice for venipuncture in patients with bilateral scarring on their forearms. Other options, such as the axillary, median cubital, and basilic veins, either present higher risks or are likely inaccessible due to the patient's condition. Thus, using the dorsal hand ensures a safer and more effective procedure.
