Question 1

What temperature must a gravity-displacement autoclave reach to achieve sterilization of unwrapped instruments?

Accepted Answer

250°F (121°C) for 15–30 minutes

Answer

Gravity-displacement autoclaves typically sterilize at 121°C (250°F) for 15–30 minutes depending on load configuration.

Question 2

Which of the following best describes the purpose of a biological indicator (spore test) in autoclave monitoring?

Accepted Answer

It verifies that the sterilization process actually killed the most resistant bacterial spores

Answer

Biological indicators use heat-resistant spores (e.g., Geobacillus stearothermophilus) to confirm that lethal conditions were actually achieved inside the load.

Question 3

In an electrology setting, which surface would be classified as a clinical contact surface requiring disinfection between clients?

Accepted Answer

The treatment table and lamp handles touched during the procedure

Answer

Clinical contact surfaces are those touched during treatment (treatment table, lamp, equipment controls) and must be disinfected between each client.

Question 4

A client presents with an active cold sore (herpes labialis) near the upper lip treatment area. What is the appropriate course of action?

Accepted Answer

Postpone treatment to that area until the lesion has fully healed

Answer

Active herpes lesions are highly contagious and electrology treatment over or near the site could spread the virus; the area must be avoided until fully healed.

Question 5

Which personal protective equipment (PPE) is considered mandatory for electrologists during all hair removal procedures?

Accepted Answer

Gloves and eye protection

Answer

At minimum, gloves and eye protection are required during electrology procedures to protect against bloodborne pathogen exposure from splatter.
