Final answer:
Doing a blood draw on interrupted or damaged skin can increase the risk of infection.
Step-by-step explanation:
When you do a blood draw on interrupted or damaged skin, it can increase the risk of infection. The skin acts as a protective barrier against pathogens, but when it is damaged, microbes can enter deeper tissues and cause infections. Wound infections can occur if bacteria enter through the broken skin and reach the bloodstream. This can lead to localized infections or even systemic infections.
