At least one of the required CE hours must cover

• A. Ethics
• B. Anatomy
• C. Sanitation
• D. Marketing

Answer: (C)

The main idea is that continuing education for license renewal must include topics that directly affect client health and safety. Sanitation fits this need because it covers keeping tools, surfaces, and workspaces clean; using proper disinfection and sterilization methods; preventing infection and cross-contamination; and safe waste handling. These practices protect clients and are typically required by licensing boards as the health and safety component of CE requirements. While ethics, anatomy, or marketing may be part of CE in some programs, sanitation is the topic most consistently mandated to ensure safe, professional care.
