Which type of barrier is most appropriate for covering the tubehead and position-indicating device (PID) during dental radiography?
Answer: Disposable plastic barrier sleeve
Impervious plastic barriers prevent contamination of surfaces that are touched during exposure.
After exposing a patient, the operator should remove contaminated gloves and then do what before touching the computer mouse or chart?
Answer: Perform hand hygiene
Hand hygiene is required after glove removal because gloves can have undetected defects.
Which item used in intraoral radiography is classified as semicritical and must be heat-sterilized or discarded after use?
Answer: Reusable film-holding device
Holders contact oral mucosa and saliva, so they are semicritical and require heat sterilization.
How should a lead apron with visible saliva contamination be handled?
Answer: Clean and disinfect it with an EPA-registered disinfectant
Lead aprons cannot be heat sterilized, so surface disinfection is used.
The Standard Precautions approach assumes that:
Answer: All patients' blood and body fluids are potentially infectious
Standard Precautions apply to all patients regardless of known infection status.
Which personal protective equipment is generally required for the operator when taking intraoral radiographs?
Answer: Gloves, mask, protective eyewear and gown
Saliva and blood exposure risk calls for full PPE during patient care.
Which disposal method is correct for a contaminated lead foil sheet from a film packet?
Answer: Place it in a designated recycling or lead disposal container
Lead foil is a hazardous material and must be recycled or disposed of according to regulations.
