Nevada State Board of Cosmetology Practice Exam

Using an improper disinfectant can lead to a possible spread of infection, which is why this is the correct answer. Disinfectants are specifically designed to eliminate or reduce harmful microorganisms on surfaces and tools used in cosmetology. If a product does not meet the necessary standards for killing bacteria, viruses, and fungi, it may not adequately clean the tools, allowing pathogens to survive.

This could result in cross-contamination when tools are reused on clients. The improper disinfectant might not be effective against specific types of germs, which means that tools that appear clean could actually harbor infectious agents. Therefore, utilizing the correct disinfectant is essential for maintaining a safe environment for both clients and practitioners by reducing the risk of transmitting infections.

The other choices do not reflect the consequences of using an improper disinfectant. For instance, claiming that there is no effect on tools ignores the health risks involved, while suggesting effective sanitation would not be realistic if the wrong disinfectant is used. Similarly, stating that there would be an improved longevity of tools does not consider that improper cleaning can actually damage tools over time.
