Infection Control, Sterilization, and Occupational Safety
The regulatory web
Infection control in Arkansas dental settings draws on board rules, CDC recommendations, and federal OSHA requirements. Candidates should distinguish clinical infection control (hand hygiene, PPE, asepsis, instrument processing) from occupational safety (bloodborne pathogens standard, exposure control plan, hepatitis B vaccination offer, post-exposure evaluation, hazard communication).
Instrument processing
Know the sequence: cleaning, packaging, sterilization, and storage, with monitoring. Sterilization must be validated - biological indicators, chemical indicators, and mechanical monitoring. Traps include assuming a chemical indicator alone proves sterility, or that a sterilizer may be used without biological monitoring records.
Sharps and waste
Sharps containers must be closable, puncture-resistant, and not overfilled. Regulated medical waste handling follows state and federal rules. Exposure incidents require immediate washing, reporting, and source evaluation.
Worked example
A staff member sustains a needlestick. The correct sequence is wash the site, report immediately, seek source-patient evaluation with consent, and document in the exposure control plan log. Rule of thumb: clinical asepsis protects the patient; the exposure control plan protects the worker - both are required, and questions often test only one.
Trap patterns
Watch for questions that treat CDC guidance as optional, or that confuse disinfection with sterilization. Also watch for single-dose vial and waterline maintenance questions.
