NHA Phlebotomy Certification Practice Exam

What do aseptic techniques aim to prevent?

1. Unintentional injury to staff

2. Infection and contamination by microorganisms

3. Accidental exposure to hazardous materials

4. Errors in patient medication administration

The correct answer is: Infection and contamination by microorganisms

Aseptic techniques are foundational practices in health care that focus on preventing infections and contamination by microorganisms. This involves methods aimed at maintaining a sterile environment and minimizing the risk of introducing pathogens during medical procedures such as phlebotomy. By employing aseptic techniques, healthcare professionals ensure that instruments, materials, and the area surrounding the procedure are free from harmful microbes, protecting both the patient and the staff from potential infections. The other choices address different concerns in healthcare. Unintentional injury to staff relates to safety protocols that minimize physical harm, while accidental exposure to hazardous materials pertains to handling chemicals or biohazards safely. Errors in patient medication administration focus on ensuring correct dosing and delivering the right medication. Although these are essential aspects of patient safety and care, they do not directly pertain to the primary goal of aseptic techniques, which is to combat infection and contamination.
