Which barrier protections must a medical assistant use when performing skin puncture or venipuncture?

When performing skin puncture or venipuncture, a medical assistant must use appropriate barrier protections to ensure safety and prevent infection. This includes wearing disposable gloves, using a mask if there is a risk of splatter, and employing protective eyewear if necessary. Additionally, it's important to use sterile equipment and to follow proper disposal protocols for sharps and contaminated materials. Adhering to these precautions helps protect both the patient and the healthcare worker.
