Knowledge of anatomy and psychology helps everything but which aspect?

• A. Disease prevention
• B. Client communication
• C. Safety protocols
• D. Record keeping

Answer: (A)

Anatomy knowledge helps you perform precise techniques, avoid damaging structures, and place pigment safely, while awareness of psychology enhances how you communicate with clients, obtain informed consent, and manage their comfort and expectations. These areas boost almost every aspect of practice, including safety protocols and how you document client histories during record keeping.

Disease prevention, however, rests primarily on infection-control practices—sterilization and disinfection procedures, proper use of PPE, single-use instruments, safe sharps handling, hand hygiene, and screening for infectious risks. These are procedural standards that aren’t driven by anatomy or psychology, but by aseptic technique and biosafety protocols. So this aspect is the one least dependent on anatomy or psychology, making it the correct choice.
