Which of the following procedures may estheticians perform that could involve contact with infected body fluids?

The correct answer identifies procedures like extractions, microdermabrasion, manicures/pedicures, and waxing as those that may be performed by estheticians and could involve contact with infected body fluids.

Extractions, for example, entail the removal of blackheads or whiteheads, which can lead to exposure to sebum and other fluids when skin is broken. Microdermabrasion involves the abrasion of the skin's surface, which can also result in minor skin wounds where fluids could be present. It's important for estheticians to practice sanitation and hygiene protocols to minimize any risk of infection or contamination during these procedures. Additionally, manicures and pedicures can involve contact with bodily fluids in cases where there are cuts or abrasions on the hands or feet.

This highlights the importance of training in hygiene and safety protocols related to these treatments to prevent the transmission of infections. Understanding how these procedures can expose estheticians to body fluids reinforces the necessity for protective measures and proper training.
