Which of the following is NOT a universal precaution recommended for health safety?

The correct answer highlights an important aspect of universal precautions, which is the necessity of hand hygiene in preventing the spread of infections. Universal precautions emphasize the importance of maintaining high standards of hygiene, including regular and thorough handwashing, to protect both healthcare workers and patients from potential pathogens.

Handwashing is a critical measure that effectively reduces the risk of transmitting infectious agents, thereby safeguarding health and promoting overall safety in care environments. Not washing hands contradicts the fundamental principles of universal precautions, which are designed to minimize the risk of infection and maintain a safe environment in healthcare settings.

In contrast, wearing a face mask, using alcohol-based sanitizer, and employing gloves when necessary are all consistent with universal precautions, as they help create barriers against potential infections.
