Ideas the questions test most

  1. Hepatitis B carries the highest infection risk after a needlestick; OSHA requires employers to offer the vaccine free within 10 working days.
  2. Alcohol-based hand rub works when hands are not visibly soiled; soiled hands are washed with soap and water.
  3. Put on gown, mask, eyewear, then gloves; take off gloves first.
  4. High-volume evacuation, the dental dam and preprocedural rinses reduce aerosols; they do not replace PPE.
  5. Standard precautions apply to every patient, whatever the medical history says.

Common questions

What order is PPE put on and taken off in?

On: gown, mask, protective eyewear or face shield, then gloves. Off: gloves first, then eyewear or face shield, gown and mask, then hand hygiene.

Does the employer have to pay for the hepatitis B vaccine?

Yes. OSHA’s Bloodborne Pathogens Standard requires employers to offer the hepatitis B vaccine series at no cost to employees with occupational exposure, within 10 working days of their assignment. Employees may decline in writing and accept later.
