What can result from a blood draw performed too aggressively?

Performing a blood draw too aggressively can lead to excessive bruising or damage to the vein. When the venipuncture site is subjected to too much force or if the needle is manipulated roughly within the vein, it can cause trauma to the surrounding tissues. This trauma results in blood leaking from the vessel into the surrounding area, forming a bruise, which is also known as a hematoma. Additionally, aggressive techniques can injure the vein itself, potentially leading to complications such as phlebitis or even the formation of blood clots.

In contrast, the other options do not hold true in the context of a forceful blood draw. Increased patient satisfaction is unlikely to result from discomfort and potential injury. Faster lab results are dependent on various factors related to the laboratory process, not the technique used to collect the blood. Lastly, improved blood flow is not a realistic outcome of an aggressive draw; in fact, it can lead to complications that might decrease blood flow to the affected area. Overall, managing the blood draw with care is essential to avoid these adverse effects.
