Infection Control · single question

All of the following help prevent transmission of mumps in the dental office EXCEPT:

  1. Verifying MMR vaccination status of every patient and staff member
  2. Ensuring adequate room ventilation and surface disinfection
  3. Using standard precautions with all patients
  4. Deferring elective care for symptomatic patients
Show answer and explanation

Correct answer: A. Verifying MMR vaccination status of every patient and staff member

  • A. Correct. Requiring proof of MMR from every patient is not a practical or standard infection-control measure. Staff immunization is recommended; screening every patient is not the control strategy.
  • B. Environmental controls reduce droplet and fomite transmission.
  • C. Mumps spreads by respiratory droplets and saliva — standard precautions are the foundation of prevention.
  • D. Deferring elective treatment for a symptomatic or infectious patient is a core control measure.
