North Dakota Barber Practice Exam 2025 – Comprehensive Prep Guide

Question: 1 / 400

What does the term "bactericidal" mean regarding disinfectants?

Substances that inhibit bacterial growth

Substances that kill bacteria

The term "bactericidal" specifically refers to substances that kill bacteria. In the context of disinfectants, when a product is described as bactericidal, it is designed to effectively eliminate or destroy bacterial cells rather than simply inhibiting their growth or reproduction.

This characteristic is crucial in settings such as barbershops, where sanitation is important to prevent the spread of infections and ensure client safety. Understanding this term helps professionals select the right products for effective disinfection and hygiene practices.

While other terms may describe disinfectants that impede bacterial growth, promote it, or sterilize surfaces, none capture the essential function of a bactericidal agent in actively killing bacteria.
