Q

Which processing method benefits the most from using film packets with a protective barrier?

A

C) Daylight loaders

Film packets with barriers are recommended due to the complexity of the infection protocol for their use.

23
Q

After removing barriers, how can film packets be processed?

A

Film packets that were packaged inside barrier envelopes may be processed with clean, dry hands because they are not contaminated.

24
Q

Is a pathosis a microorganism capable of causing disease?

A

FALSE

A pathogen is a microorganism capable of causing disease. Pathosis refers to the disease itself.

25
Q

Are infection control protocols carried out only if the patient is known to be infectious?

A

FALSE

Infection control protocols are applied to all patients to prevent risk.

26
Q

Should the lead apron be sterilized after use?

A

FALSE

The lead apron should be disinfected after use, as it is a noncritical object.

27
Q

What does sterilization refer to?

A

Sterilization refers to total destruction of spores and disease-causing microorganisms.

28
Q

Should powdered gloves be used when placing intraoral radiographs?

A

FALSE

Powdered gloves should be avoided as they can cause radiographic artifacts.

29
Q

Is sterilization the use of a procedure to reduce pathogens to an acceptable level?

A

FALSE

Disinfection reduces pathogens; sterilization is total destruction of microorganisms.

30
Q

Must semicritical objects be sterilized after use?

A

TRUE

Semicritical objects touch but do not penetrate soft tissue or bone.

31
Q

Should barrier materials be placed over surfaces likely to be contaminated?

A

TRUE

Barrier wrap is recommended to prevent contamination during procedures.

32
Q

What are noncritical objects?

A

Noncritical objects are those that do not come into contact with mucous membranes.

33
Q

Should the radiographer open all film packets in a timely manner?

A

TRUE

Prolonged exposure to light increases the risk of fogging the film.

34
Q

Should protective clothing be in place before putting on treatment gloves?

A

TRUE

Protective clothing, mask, and eyewear should be worn prior to handwashing.

35
Q

Must darkroom counter surfaces touched by gloved hands be cleaned?

A

FALSE

They must be disinfected.

36
Q

What is the goal of infection control?

A

The goal is the prevention and reduction of disease-causing microorganisms.

37
Q

Does occupational exposure refer to an infection a patient might be exposed to?

A

FALSE

Occupational exposure refers to a worker coming in contact with infectious materials.

38
Q

Should radiographers be vaccinated against certain diseases?

A

TRUE

The CDC recommends vaccination for dental personnel working with blood.

39
Q

Is spatter a suspension of microorganisms produced during normal breathing?

A

FALSE

Microbial aerosols are the suspension in air of microorganisms produced during breathing.

40
Q

Have universal precautions replaced standard precautions?

A

FALSE

Standard precautions have replaced the universal precautions concept.

41

Can taking a medical history identify potential infected patients?

A

TRUE

Some patients may be reluctant to admit their infectious condition.

42
Q

Does the CDC enforce infection control regulations?

A

TRUE

The CDC does not enforce regulations but influences guidelines.

43
Q

Is the lead apron considered part of personal protective equipment (PPE)?

A

FALSE

PPE includes clothing, masks, eyewear, and gloves, but not the lead apron.

44
Q

What is an antiseptic?

A

An agent used on living tissues to destroy bacteria or halt their growth.

45
Q

How often should protective clothing be changed?

A

Daily, or more frequently if soiled or wet.

46
Q

Why should the radiographer open all film packets in a timely manner?

A

Prolonged exposure to light increases the risk of film fog.

47
Q

How should films secured in barrier envelopes be handled?

A

They may be handled with clean, dry hands or new treatment gloves.

48
Q

What are infectious diseases?

A

Diseases that occur through transmission of microorganisms between patients and personnel.

Q

How can the chain of infection be broken?

A

By immunization, removal of pathogens, or blocking the portal of entry.

What is asepsis?

A

Absence of septic matter or freedom from infection.
