What can happen if you do a blood draw on interrupted (damaged) skin?

A. Reduced risk of contamination
B. Increased risk of infection
C. Decreased risk of hematoma
D. Quicker clotting of blood

The correct answer is: B. Increased risk of infection

Performing a blood draw on interrupted or damaged skin significantly increases the risk of infection. When the skin is damaged, the protective barrier it usually provides is compromised, making it easier for pathogens to enter the bloodstream. Proper skin integrity is crucial in medical procedures since intact skin acts as a primary defense mechanism against infections. Therefore, blood draws should always be conducted on healthy, undamaged skin to minimize this risk and promote patient safety. In contrast, the other options would not apply in this scenario. Reduced risk of contamination isn't feasible when the skin barrier is compromised, as it directly invites pathogens. Decreased risk of hematoma is also not relevant because damaged skin could potentially lead to more bruising or hematoma formation, rather than decreasing the risk. Moreover, quicker clotting of blood would not directly relate to the condition of the skin. The healing process and clotting are more contextually tied to the physiological response than the state of the skin at the draw site.
